It should be understood that, in the various embodiments of the present application, the size of the serial numbers of each implementation process does not mean the sequence of execution, and the execution sequence of each process should be determined by its functions and internal logic, and should not be dealt with in the embodiments of the present application. implementation constitutes any limitation.

The privacy document in the embodiments of the present application has a narrow definition and a broad definition. Among them, the narrow definition: privacy documents include any documents, documents, etc. that are reasonably required for privacy protection in practical applications. For example, ID cards, social security cards, driver's licenses, passes, passports, etc. Also, for example, contracts, agreements, etc., in which confidential information is written. In a broad sense, privacy files include not only the aforementioned certificates, documents, etc., but also images, files, videos and other contents with any privacy information.

Compared with the solution in the related art in which the display of the privacy file cannot guarantee the privacy of the user, the technical solution of the embodiment of the present application - realizing the display of the target privacy data in the privacy file based on the target parameter, is to display the usage according to the usage scenario. The privacy data required in the scenario provides a technical support. Reasonable display of the private data in the privacy file is realized according to the usage scenario of the electronic device, thereby ensuring the privacy of the private data that is not required in the usage scenario, and improving the protection security of the private data.

The processing logic of the method for displaying data according to the embodiment of the present application may be deployed in any reasonable electronic device. The electronic device may be a terminal or a server. The terminals include but are not limited to tablet computers, all-in-one computers, desktop computers, mobile phones, smart speakers, smart watches, and the like. Servers include ordinary servers, cloud servers, and the like.

An implementation process of the method for displaying data according to the embodiment of the present application, as shown in FIG. 1 , the method includes:

S101: Acquire a target parameter, where the target parameter represents a usage scenario in which the electronic device is located; the electronic device includes a privacy file, and the privacy file includes at least two privacy data;

In this step, the private data may be data related to user personal information, company or unit personal information. Wherein, the user's personal information includes but is not limited to the user's name, gender, address, ID number, passport number, user photo, etc. The personal information of a company or unit includes, but is not limited to, the name of the legal person, the name of the shareholder, the place of registration, the registered capital, etc.

The privacy file may be a file that embodies the above privacy data in the form of text, or may be a file that embodies the privacy data in the form of an image, that is, a privacy file as an image. Usually, one privacy file includes two or more privacy data.

In practical applications, privacy documents such as ID cards and medical insurance cards are usually used in different usage scenarios. For example, ID cards will be used in banks, real estate trading halls, nucleic acid sampling offices and other usage scenarios. Medical insurance cards will be used in hospitals, insurance companies and other usage scenarios.

S102: Determine target privacy data from the at least two privacy data based on target parameters;

In this step, the target privacy data is the privacy data that needs to be displayed in the usage scenario represented by the target parameter. It can be one, or two or more private data matching the target parameter in all the private data of the private file. The private data matching the target parameter is the private data that needs to be displayed in the usage scenario represented by the target parameter.

Exemplarily, if the target parameter represents the current usage scenario of the electronic device in a bank, the target privacy data matching the target parameter may be the user's name, ID number, etc. on the ID card. When displaying, the user name and ID number on the ID card can be displayed.

If the target parameter indicates that the current electronic device is used in a hospital, the target privacy data matching the target parameter may be the patient's name, medical insurance card number, etc. on the medical insurance card. When displaying, the patient's name and medical insurance card number on the medical insurance card can be displayed.

The correspondence between the target parameters in different usage scenarios and the privacy data in the privacy files to be used in the usage scenarios may be preset as the first correspondence. When in use, the private data corresponding to the target parameter can be read from the first correspondence relationship as the target private data under the target parameter.

It can be understood that if the usage scenarios are different, the target privacy data determined based on the target parameters may be different. Based on this, the display of the private data that needs to be displayed in each usage scenario can be realized according to different usage scenarios.

S103: Display the target privacy data.

In this step, the target privacy data can be displayed in any reasonable manner. For example, taking a privacy document as an ID card as an example, the target privacy data is displayed in the form of an ID card. In this case, it can be understood as: the ID card is displayed, the information on the ID card as the target privacy data such as the user name and ID number can be displayed, and the information that is not used as the target privacy data is not displayed or in the form of mosaic to display. For another example, the target privacy data that needs to be displayed is displayed on the display screen according to a certain arrangement format, such as the format of the user's name in the front and the ID number in the back. Alternatively, it is displayed in a random arrangement format, as long as all the private data that needs to be displayed in the usage scenario are displayed.

In S101-S103, for the privacy file, the privacy data (target privacy data) that needs to be displayed in the usage scene among all the privacy data of the privacy file may be determined based on the target parameter representing the usage scene of the electronic device, and Display the private data that needs to be displayed in the usage scenario. Provides a technical support for the privacy file to display the privacy data required in the usage scenario according to the usage scenario. Reasonable display of the private data in the privacy file is realized according to the usage scenario of the electronic device, thereby ensuring the privacy of the private data that is not required in the usage scenario, and improving the protection security of the private data.

It should be noted that, for the same privacy file, the privacy data that needs to be displayed in different usage scenarios may be different. In response to this situation, a correspondence relationship between target parameters in different usage scenarios and privacy data to be used in the usage scenario for the same privacy file may be preset as the first correspondence relationship. When it is used, the privacy data corresponding to the acquired target parameter can be read from the first correspondence relationship as the target privacy data under the target parameter. It can be seen that, in the embodiment of the present application, the same privacy file can display different privacy data according to different usage scenarios.

In the embodiment of the present application, when the privacy file is saved, the privacy data may be saved in the form of plaintext data. That is, the private data in the private file is plaintext data, that is, data that is not encrypted. The target privacy data determined based on the target parameter in this embodiment of the present application may be one or more privacy data in the privacy file, or may also be plaintext data. For example, the target privacy data in S101 to S103 is plaintext data. The display of the target private data is directly performed when the target private data is determined based on the target parameters.

In addition, considering the (saving) security and privacy of the data, the target privacy data determined based on the target parameters may also be ciphertext data. That is, the target privacy data may be data obtained by encrypting the privacy data matching the target parameter among all the privacy data in the privacy file (as shown in S1021 in FIG. 2 ).

In response to this situation, it is necessary to encrypt the private data that will be used in each usage scenario, and then record the correspondence between the target parameters in different usage scenarios and the encrypted private data that will be used in the usage scenario, as The second correspondence. When it is used, the encrypted privacy data corresponding to the target parameter can be read from the second correspondence relationship as the target privacy data under the target parameter.

Based on this, as shown in Figure 2, S103 includes:

S1031: Decrypt the target privacy data;

S1032: Display the decrypted data.

In S101 , S1021 , S1031 and S1032 , in order to improve the protection security of private data, it is necessary to encrypt the private data to realize safe storage. In order to realize the normal display of the private data, when the encrypted private data (target private data) is determined based on the target parameters, the target private data is decrypted and then displayed. Thereby, not only the protection security of private data is improved, but also the normal display of private data is realized. The normal display of private data here may include at least one of the following two meanings: the private data is successfully displayed; the encrypted private data is displayed in the form of the original data (private data itself, unencrypted), that is Restore encrypted private data.

It can be understood that the encryption of the privacy data in the embodiment of the present application is to realize the safe preservation of the privacy data in the electronic device, so that the privacy file can be used normally, so that the privacy caused by the malicious cracking of the unscrupulous person can be effectively avoided. The problem of data leakage.

In the above solution, the decryption of the target privacy data can be implemented by one of the following implementation methods:

Implementation mode 1: Decrypt the target privacy data based on the collected physiological characteristic information of the preset user and/or the input character information.

In implementation manner 1, the preset user may be a reasonable user of the electronic device, such as the owner himself. The character information may be character information such as numbers, characters, underscores, and asterisks input by the user. The physiological feature information includes, but is not limited to, the following: at least one of a fingerprint, a voiceprint, and an eye mask. The target private data is decrypted by using at least one physiological feature information of the owner's own fingerprint, voiceprint and eye mask. In this case, the physiological characteristic information of the owner can be regarded as a decryption password for decrypting the target private data. The physiological feature information is obtained based on the fingerprint recognition module, voiceprint recognition module, and eye mask recognition module of the electronic device collecting fingerprints, voiceprints, and eye masks. The inputted character information and biometric information here are used as decryption keys.

Compared with the following implementation mode 2, in the implementation mode 1, the decryption of the encrypted privacy data based on the character information and/or physiological characteristic information input by the user is realized, that is, the decryption of the encrypted privacy data is realized based on the participation of the user, Thus, the normal display of private data is realized.

Implementation mode 2: Based on the encryption key of the private data matching the target parameter, obtain the target decryption key; based on the target decryption key, decrypt the target private data.

In the second implementation, different key pairs are randomly generated. Usually, the number of generated key pairs is consistent with the amount of private data in the private file. Assign a key pair to each private data. Each key pair includes an encryption key and a decryption key. That is, each private data is assigned an encryption key and a decryption key that forms a key pair with the encryption key. The encryption key is used to encrypt the private data to which the encryption key is allocated. The decryption key is used to decrypt the encrypted private data.

Here, it can be understood that the private data matching the target parameter is encrypted by using the encryption key allocated for the private data matching the target parameter. The decryption key that forms a key pair with the encryption key is used as the target decryption key, and the target decryption key is used to decrypt the private data encrypted by the encryption key. Generally speaking, for a certain privacy data and the key pair allocated for the privacy data, use the encryption key of the key pair to encrypt the privacy data, and then use the decryption key of the key pair to encrypt the encrypted data. decrypt the private data.

Among them, using the encryption key for encryption can improve the security protection of the private data, and effectively avoid unnecessary leakage of the private data. The decryption based on the decryption key realizes the normal display of the private data that needs to be displayed in different usage scenarios, and improves the user experience.

It can be understood that in the same usage scenario, the private data matching the target parameters in all the private data of the privacy file can be encrypted data, and the remaining private data in all the private data except the private data matching the target parameters can be. It is plaintext data, that is, data that is not encrypted. All the private data in the private file except the private data matching the target parameter may also be encrypted.

Exemplarily, in the usage scenario of a bank, for the privacy document of the ID card, assuming that the privacy data matching the target parameters are the user name, ID number and user photo, then the user name, ID number and user photo on the ID card are Photos, etc. can be encrypted, and the remaining private data on the ID card, such as gender, date of birth, and home address, may not be encrypted, but can be used as plaintext data or encrypted. The scheme in which the remaining private data on the ID card is encrypted, on the one hand, can improve the security of the protection of private data, and on the other hand, it can be adapted to the privacy data that needs to be displayed such as gender, date of birth, and home address. The usage scenario is more practical, and the solution is easy to promote in engineering.

For the scheme in which the private data matching the target parameters in the privacy file and the other private data except the private data matching the target parameters need to be encrypted, the private data matching the target parameters can be encrypted by using a certain encryption algorithm , and the rest of the private data can also be encrypted by a certain encryption algorithm. The encryption algorithm used for the privacy data matching the target parameter and the encryption algorithm used for the other privacy data may be the same or different.

Encryption algorithms include but are not limited to the following: Hash algorithm, Symmetric Cryptosystem Encryption (DES) algorithm, RSA encryption algorithm, Advanced Encryption Standard (AES) algorithm and the like.

The number of private data matching the target parameters can be two or more. The number of the remaining private data except the private data matching the target parameter among all the private data of the private file may be two or more. The private data matching the target parameters and/or the remaining private data may be encrypted by using the same encryption algorithm, or encrypted by using different encryption algorithms.

The encryption of the private data in the embodiment of the present application realizes the security protection of the private data, and effectively avoids malicious tampering.

As an optional solution, each of the private data matching the target parameter and the remaining private data is encrypted with its own encryption key. That is, all private data of the private file are encrypted with their respective encryption keys. Each privacy data in the privacy file is encrypted with different encryption keys, which can improve the security protection of the privacy data and avoid malicious cracking of the privacy data.

The encryption key may be a different key randomly generated for each private data, or an encryption key used to encrypt each private data in a different key pair randomly generated for each private data.

In the case where the encryption key is an encryption key used to encrypt each private data in a different key pair randomly generated for each private data, the decryption of the private data matching the target parameters can be performed by assigning the private data to the private data. The decryption key in the key pair decrypts the encrypted private data.

In the case where the encryption key is a different key randomly generated for each private data, the decryption of the private data matching the target parameters can be realized by the way based on the host's own physiological characteristic information to realize the decryption of the encrypted private data.

When the remaining private data is encrypted, when displaying the decrypted private data matching the target parameters, the remaining private data may not be displayed, or displayed in the form of mosaic, or displayed as encrypted data. In order to realize the normal display of private data required in different usage scenarios.

As an optional solution, the privacy file may be an image including privacy data, such as an image obtained by taking a photo or scanning an ID card or a medical insurance card. Or, take pictures with private data for everyday life. The image includes two or two private data, such as the user's name, gender, ID number, date of birth, user photo, home address, etc. on the ID card. For example, everyday images that include your own license plate number, include everyday images of landmarks near your home address. If the above privacy data is all the content of the image, the target privacy data that needs to be displayed is a part of all the content in the privacy image. In the case where the aforementioned image is regarded as a privacy image, this solution can realize the display of part of the privacy content in the privacy image according to the usage scenario of the electronic device. A technical support is provided for the privacy image to display the privacy content required in the usage scenario according to the usage scenario.

In this embodiment of the present application, the location and/or time of the electronic device may be acquired, and the target parameter may be determined based on the location and/or time of the electronic device. The location of the electronic device can be known through a positioning module of the electronic device, such as a global positioning system (GPS). If the GPS shows that the current location of the electronic device is a bank, target parameters representing the usage scenario of being in a bank are generated. If the GPS shows that the current location of the electronic device is a hospital, target parameters representing the usage scenario of being in a hospital are generated. The electronic device can know the time of itself based on the time synchronization with the network side. The electronic device finds out that the user usually does nucleic acid sampling between 7:00 and 8:00 on Tuesday through statistics of the user's behavioral trajectory and/or behavioral habits for a period of time. . If the electronic device knows the current time, such as 7:00-8:00 on Tuesday, it generates target parameters representing the usage scenario of being at the nucleic acid sampling point. In this way, the accurate acquisition of the target parameters is achieved, thereby realizing accurate determination and display of the target privacy data based on the accurately acquired target parameters.

Because there are many privacy documents in practical applications, such as ID cards, social security cards, driver's licenses, etc. Different privacy files need to be used in different usage scenarios. The privacy files that need to be used in different usage scenarios need to be preset. For example, in the usage scenarios of banks or nucleic acid sampling sites, set the ID card as the privacy document in this usage scenario. For example, in the usage scenario of a hospital, set the medical insurance card as a privacy file in this usage scenario.

The technical solution of the present application will be further described below with reference to FIGS. 3 to 6 .

First, the storage process of the privacy file in the technical solution of the present application will be described.

Taking the private document as an ID card as an example, the private image of the ID card is obtained by taking a photo or scanning it. Usually, the ID card includes several basic elements such as name, gender, ethnicity, date of birth, address, photo and ID number. Treat each basic element as a piece of private data.

The electronic device randomly generates N different key pairs. N is a positive integer greater than 1, and the value of N is the same as the number of basic elements on the ID card. Assign each key pair to each base element. As shown in Figure 3, key pair 1 is assigned to the basic element of name, key pair 2 is assigned to the basic element of gender, key pair 3 is assigned to the basic element of ethnicity, and key pair 4 is assigned to the basic element of photo. A basic element, key pair 5 is assigned to the basic element of ID number, and so on, until all basic elements are assigned key pairs.

Each key pair includes an encryption key and a decryption key. Each basic element on the ID card is encrypted using the encryption key in each key pair. For example, the basic element of name is encrypted with the encryption key in key pair 1, the basic element of gender is encrypted with the encryption key in key pair 2, and so on, until the basic element of key pair N is encrypted The encryption key in encrypts the last base element.

Save or store the encrypted basic elements in the electronic device. Specifically, the storage or storage may be that each basic element is stored in the private image of the ID card in an encrypted form, thereby realizing the encrypted storage of the private data for subsequent use. In subsequent use, the privacy image of the same privacy document, such as an ID card, can display different privacy data according to different usage scenarios.

It can be understood that the basic elements on the ID card are stored in encrypted form in the privacy image of the ID card. FIG. 4 is a schematic diagram of the preservation effect of each encrypted basic element in a private image. As shown in Figure 4, XXX, YYY, ZZZ, etc. in Figure 4 represent the presentation effect after encrypting each basic element on the ID card, and the electronic device saves the privacy image of the ID card in this form.

As shown in FIG. 3, M usage scenarios of the ID card file are provided, where M is a positive integer greater than 1. For example, ID cards can be used in different usage scenarios such as banks, police stations, real estate trading halls, and nucleic acid sampling points. Based on this, in the application scenario shown in FIG. 5 , the current location of the electronic device displayed by GPS is taken as an example of a bank. In the case where the current location is a bank, the electronic device generates a usage scenario that represents the usage scenario of the bank. target parameter. The electronic device calls the ID card files in the multiple privacy files as the privacy files that need to be used in the usage scenario of the bank.

The electronic device reads the preset second correspondence, if the second correspondence states that the private data to be displayed on the ID card corresponding to the target parameter representing the usage scenario of the bank is the user's name, ID number, photo, etc. For several basic elements (target privacy data), the encrypted basic elements are decrypted by using the decryption key in the key pair allocated for these basic elements.

For example, decrypt the encrypted user name with the decryption key in key pair 1; decrypt the encrypted photo with the decryption key in key pair 4; decrypt the encrypted identity with the decryption key in key pair 5 The certificate number is decrypted.

In the case of decrypting the basic elements that need to be displayed in the usage scenario of the bank, the ID card is displayed. As shown in Figure 6, on the displayed ID card, the decrypted basic elements such as user name, ID number and photo are displayed in plaintext, and the remaining basic elements are displayed in ciphertext. The rest of the basic elements can also be displayed in the form of mosaic, or the basic elements without decryption are not displayed on the ID card.

When the ID card is regarded as a privacy image, and the basic elements on the ID card are regarded as all the content of the privacy image, the above scheme realizes the display of part of all the content of the privacy image. It can be seen that the technical solution of the present application can realize the display of part of the privacy content in the privacy image according to the usage scenario of the electronic device.

For the privacy document of the ID card, if the usage scenario is different, such as the real estate transaction hall, assuming that the name and ID number on the ID card file need to be used in this usage scenario, the name and ID number are determined as the target privacy data, the name and ID number need to be decrypted and displayed, and the rest of the basic elements do not need to be decrypted. It can be seen that the embodiments of the present application provide a technical support for the private image to display different private data according to different usage scenarios.

The above decryption adopts the decryption performed by the decryption key in the key pair. In addition, each basic element that needs to be decrypted can also be decrypted based on the collected physiological characteristic information of the owner. That is, the physiological characteristic information of the owner himself can be regarded as a decryption password.

Exemplarily, when a fingerprint of the owner himself is collected, the decryption of each basic element that needs to be decrypted is implemented. That is, the fingerprint is the decryption password for decrypting all basic elements that need to be decrypted.

Alternatively, when different fingerprints of the owner himself are collected, decryption of each basic element that needs to be decrypted is implemented one by one. For example, when the fingerprint of the index finger is collected, the encrypted name is decrypted; when the fingerprint of the middle finger is collected, the encrypted ID number is decrypted. Different fingerprints can be regarded as decryption passwords for different basic elements.

Alternatively, the decryption fingerprints of two or more different basic elements that need to be decrypted are preset as the same fingerprint, and the decryption fingerprints of the other basic elements that need to be decrypted are another fingerprint.

The above situation is that all basic elements that need to be decrypted use the decryption key in the key pair to decrypt the physiological characteristic information as an example. In addition, it can also be preset that some encrypted basic elements are decrypted by means of a decryption key, and some encrypted basic elements are decrypted by means of physiological characteristic information. Please refer to understanding.

It can be understood that, in the foregoing solution, using an encryption key for encryption can improve the security protection of private data, and effectively avoid unnecessary leakage of private data. Decryption based on the decryption key or physiological feature information realizes the normal display of private data that needs to be displayed in different usage scenarios, and improves user experience.

Generally speaking, in this application, the privacy file is divided into different elements (basic elements), then encrypted and saved with different keys (such as encryption keys), and only decrypted according to different usage scenarios when needed. The privacy data required by the user is displayed.

Different from the display of the entire privacy file, that is, all the privacy data in the privacy file in the related art, there is a risk of privacy leakage. In this solution, only the privacy data required by the user is decrypted and displayed according to different usage scenarios, which can reduce the risk of privacy leakage. Avoid unreasonable users' privacy snooping.

The aforementioned solution is a solution in which the electronic device automatically generates target parameters based on its own location and/or time; and determines target privacy data based on the target parameters. In addition, considering that in practical applications, there may be private documents such as ID cards, medical insurance cards, and driver's licenses that are used in unexpected situations. In this case, the present application also supports manual invocation of the privacy file, manual selection and automatic display of the privacy data that the user desires to display in the privacy file. It can improve the user experience.

Exemplarily, each basic element in privacy documents such as ID cards, medical insurance cards, and driver's licenses is stored in an electronic device in an encrypted form. In a sudden usage scenario, the user manually selects the privacy document he needs, such as an ID card, and displays it. Because the basic elements on the ID card displayed on the display screen of the electronic device are encrypted data, the user can select the basic elements he needs on the display screen, and then input the specified physiological characteristic information into the electronic device. For example, in response to the user's selection operation, the electronic device regards the selected basic elements on the display as private data that needs to be decrypted, and realizes the basic elements that need to be decrypted when the designated fingerprint of the owner is collected. decryption, and display the decrypted basic elements, that is, the restored basic elements will be displayed.

Alternatively, each time the user selects a basic element on the display screen, a fingerprint that can decrypt the basic element is input to the electronic device. The basic elements are decrypted and displayed. It realizes the one-by-one selection, one-by-one decryption and one-by-one display of the basic elements it needs.

Of course, in the scheme of selecting and decrypting one by one, the decrypted basic elements can also be displayed at the same time. For example, in the case where the last basic element is decrypted, the basic element and its previous decrypted basic elements are simultaneously displayed on the display screen.

When there are two or more basic elements to be decrypted, the fingerprint of the same finger or the fingerprints of different fingers can be used between different basic elements to be decrypted. It is also possible to use fingerprints of the same finger for some basic elements, and fingerprints of different fingers for some basic elements. In this embodiment of the present application, in addition to using a fingerprint for decryption, a voiceprint or an eye mask can also be used for decryption.

When decrypting two or more basic elements that need to be decrypted, one of fingerprint, voiceprint and eye mask can be used for decryption, or at least two of the three can be mixed for decryption.

To sum up, the technical solutions of the embodiments of the present application can also realize decryption and normal display of basic elements required by the user in the privacy file based on the user's participation. It can be seen that the technical solutions of the embodiments of the present application have high practicability and wide application range.

The above scheme is to save the basic elements in the privacy file in the form of ciphertext. In practical applications, each basic element in the privacy file can also be stored in plaintext. When the target parameter is acquired, the first correspondence is read, and the privacy data corresponding to the target parameter is read from the first correspondence as the target privacy data. At this time, the target privacy data is plaintext data, and the display screen of the electronic device can directly display the target privacy data. For the private data that is not required in the usage scenario represented by the target parameter, it may not be displayed, or it may be displayed in the form of a mosaic. In this way, only the private data required by the user is displayed according to the usage scenario, and the risk of leakage of unnecessary private data is reduced.

The technical solution of the present application will be further described below by taking the example shown in FIG. 7 .

The privacy file is divided into basic elements, as shown in Figure 7. There are two kinds of labels (labels) available for each basic element, one of which is the default label (Defaultlabel) and the other is the private label (privacylabel). The user can select a label for each basic element. The basic element selected as the default label needs to be encrypted and decrypted with the default key (Default key). The basic elements selected as private labels need to be encrypted and decrypted with a private key (Privacy key). Alternatively, the selected basic elements among all the basic elements are encrypted and decrypted by using the private key, and the remaining non-selected basic elements are encrypted and decrypted by default using the default key. Labels can be selected for each basic element according to actual usage requirements. In some scenarios, all base elements may be selected as default labels, or all base elements may be selected as private labels.

For the scenario where the privacy document is an ID card, among all the basic elements of the ID card, the name and ID number can be used as elements with default labels. The rest of the base elements can be considered as elements with private tags.

Create a secure space or private space for the electronic device, and save the default key and/or the private key in the secure space. The default key and/or the private key can be read from the secure space until the base element is decrypted if required for use. The base element with the default label is decrypted with the default key, and the base element with the private label is decrypted with the private key.

It can be understood that since the safe space or private space has certain confidentiality and security, using the safe space to save the default key and private key can improve the security and confidentiality of key storage and avoid malicious keys. tamper.

In addition, in order to strengthen the access security of the safe space, an access password can be set for the access to the safe space in advance, and the key stored in the safe space can be read only when the access password input by the user is authenticated and passed. This further enhances security.

In this application scenario, the origin of the default key is: in the secure space, a random number is generated for each basic element selected as the default label, and each generated random number is encrypted using the elliptic encryption (ECC) algorithm to obtain each default key. key. Each selected basic element of the default label is encrypted correspondingly using each default key to obtain each encrypted default element (the basic element of the default label).

Exemplarily, the basic elements of the default label include element 1 and element 2, the random numbers generated for element 1 and element 2 are random number 1 and random number 2, and ECC encryption is performed on random number 1 and random number 2 to obtain the default password. Key 1, Default Key 2. Element 1 is encrypted with default key 1, and element 2 is encrypted with default key 2 to obtain encrypted data of element 1 and element 2.

When it is used, for the default element in the privacy file, if the operation of unlocking the electronic device, such as inputting the power-on password, is used as the access password for entering the safe space, and the electronic device recognizes that the access password entered by the user is correct, the user can enter the safe space. Read default key 1, default key 2 from the secure space. Use the default key 1 and the default key 2 to decrypt the encrypted element 1 and element 2 respectively, and display the decrypted data. The Default documentation (default element file) in Figure 7 is directly presented to the user, and the elements that are defaultlabel in the Default documentation are displayed in plain text.

It can be seen from the foregoing that the default key in this application scenario is obtained based on a random number automatically generated by the electronic device. The private key can be obtained based on the input password collected by the electronic device. The origin of the private key is: collect the password entered by the user, encrypt the password entered by the user with the ECC algorithm, and obtain each private key. Each selected basic element of the private label is correspondingly encrypted using each private key to obtain each encrypted private element (the basic element of the private label).

The password input by the user may be characters such as numbers, letters, and underscores, and may also be physiological characteristic information, such as fingerprints, voiceprints, and eye masks. In terms of implementation, when the number of private elements is two or more, each private element can be encrypted by using a private key obtained based on a password entered by the same user. It is also possible that each private element corresponds to a user-input password, and each private element is encrypted with a private key obtained based on the corresponding user-input password. Alternatively, some of the private elements correspond to the same user's input password, and some of the private elements are encrypted with a private key obtained based on the same user's input of the password. This is not specifically limited.

Exemplarily, the basic elements of the private label include element 3, element 4, and element 5. The user input password corresponding to element 3 is the fingerprint of finger 1, the user input password corresponding to element 4 is the fingerprint of finger 2, and the user input password corresponding to element 5 is the fingerprint of finger 2. The input password is the fingerprint of finger 3, and the fingerprints of finger 1, finger 2, and finger 3 are encrypted by ECC respectively to obtain private key 1, private key 2, and private key 3. Element 3 is encrypted with private key 1, element 4 is encrypted with private key 2, and element 5 is encrypted with private key 3 to obtain encrypted data of element 3, element 4, and element 5.

When it is in use, for the private element in the privacy file, if the operation of unlocking the electronic device, such as inputting the power-on password as the access password for entering the safe space, enters the safe space when the electronic device recognizes that the access password entered by the user is correct, Read Private Key 1, Private Key 2, and Private Key 3 from the secure space. Use private key 1, private key 2, and private key 3 to decrypt encrypted element 3, element 4, and element 5, respectively, and display the decrypted data.

In the above solution, the private elements to be displayed can be preset, and based on the settings, the private elements to be displayed are automatically selected and decrypted. In addition, for the private element, the user can manually select the desired private element in a usage scenario, and decrypt the selected private element after the manual selection.

In terms of specific implementation, the electronic device can present the identifiers of private elements that can be manually selected by the user (such as words such as "gender", "name family", etc. on the ID card) in the form of a menu, and the user selects from the menu to be displayed or the basic element to be displayed, click the logo of the basic element that needs to be displayed or displayed. The electronic device identifies the private element selected by the user and needs to be displayed, collects the access password, and reads the private key from the secure space that can decrypt this or these selected private elements when the access password authentication passes, and uses the private key Decrypt and display the decrypted data. If the electronic device presents the Privacy documentation (private element file) in FIG. 7 to the user, the Privacy documentation may contain both default elements and private elements selected by the user. Default elements and user-selected private elements are shown in clear text in the Privacy documentation.

The collected access password may be the collected password for each selected private element and input by the user after selection. When the access code is passed, the private key of the selected private element is read from the secure space and decrypted and displayed.

The access password may be additionally collected numbers, letters and other characters input by the user, or fingerprints, voiceprints, eye masks, etc. as the access password. It is also possible to use the user input password that needs to be encrypted with the ECC algorithm to obtain the private key in the private key origin scheme as the access password to the secure space without additional collection. One or more of the user input passwords that need to be encrypted with the ECC algorithm to obtain the private key in the private key origin scheme are selected as the access password.

The number of access passwords for the safe space may be one, and after all the selected private elements are selected, the user inputs the selected access password. Alternatively, there are multiple access passwords for the safe space, for example, one access password is input after each private element is selected, or one access password is input after each two or more private elements are selected. It depends on the actual application.

In the scheme of entering an access password after each selected private element, the access password entered after each selected private element must be the origin of the private key of each selected private element. In the scheme, the ECC algorithm needs to be encrypted to obtain the private key The user of the key enters the password.

Exemplarily, if in the private key origin scheme, element 3 is used as a private element, and its private key is obtained by encrypting user fingerprint 1 using the ECC algorithm. If the user selects element 3 in the manual selection of private elements to be displayed, after selecting element 3, the user needs to input fingerprint 1 as the access password for accessing the private key of element 3 in the secure space.

That is, in the scheme of inputting an access password after each selection of a private element, the access password input after each selection of a private element can be used as the password for accessing the private key of the private element.

In the aforementioned solution, only when the correct access password is input, the private key of the private element to be displayed can be successfully accessed. It provides a security line of defense for the decryption of private elements, realizes the secure decryption of private elements, and can effectively reduce the risk of private data being leaked.

The above input scheme for the access password is not limited to the process of manually selecting the private element to be displayed, but also applies to the scheme of automatically selecting and decrypting the private element to be displayed.

It can be understood that, in the foregoing solution, the location and/or time where the electronic device is located is used to determine the usage scene where the electronic device is located. For example, the location and/or time of the electronic device can be used to distinguish which usage scenarios the electronic device is in, such as a bank, a school, a real estate transaction hall, or a police station. In this way, different privacy data can be displayed according to different usage scenarios.

In practical applications, in addition to differentiating usage scenarios where the electronic device is located according to the location and/or time of the electronic device, different usage scenarios can also be differentiated according to different objects for viewing images, videos, and texts. The object here mainly refers to people. Different objects mainly refer to people in different roles. For example, adults, children, acquaintances, strangers, close acquaintances, non-close acquaintances, etc. Since each person may have more than one role in practical applications, any reasonable role object may be within the protection scope of the embodiments of the present application.

The technical solution of the present application can distinguish different usage scenarios according to different objects of viewing images, videos and texts, determine the content to be displayed from the privacy file according to different objects, and display the content to be displayed. That is, the display of different contents in the privacy file is realized according to different usage scenarios. In short, different contents in the privacy file can be displayed according to different objects.

In the technical solution of the present application, the privacy file may be an image, a video, a text, or the like. If the private file is a video, the video contains private content. Based on the role of the viewing object, the nursing content in the video that matches the viewing object can be intercepted and displayed to the viewing object.

Exemplarily, for video A that includes nursing of the private parts of the body of children, nursing of the private parts of the body of adults, nursing of the private parts of the elderly, etc., the electronic device can be viewed based on the recognition of the face of the viewing object. The target is children, adults, or the elderly. If it is identified that the viewing object is a child, the nursing content of the child's private part in video A is determined as the target privacy data, the video part of the nursing content of the child's private part is intercepted from video A, and the intercepted video part is displayed. If it is recognized that the viewing object is an adult, the nursing content of the adult's private part in the video A is determined as the target privacy data, the video part of the nursing content of the adult's private part is cut out from the video A, and the intercepted video part is displayed.

Among them, it is necessary to bind the different roles of the viewing objects in advance with the video content parts that the viewing objects belonging to different roles should watch in video A, so that the content that the viewing objects should watch can be determined based on the roles of the viewing objects. , and then realize the accurate interception of the video part to be displayed from the video A.

If the private file is an image, the image contains private content. Based on the roles of the viewing objects for the image, the electronic device may provide different image content in the same image for viewing by different viewing objects.

Exemplarily, the owner of the electronic device stands in front of the newly purchased private car and takes a photo, which contains the license plate number and logo of the car (the license plate number and logo can be regarded as the owner's own). privacy information). The owner himself can publish the photo on the Internet through an electronic device, such as publishing it on the Internet by sending it to a circle of friends. For this photo published by the owner himself on the Internet, using the technical solutions of the embodiments of the present application, friends with different relationships in the circle of friends see different content. According to the degree of intimacy of the friends, the friends in the owner's own circle of friends are divided into family members, relatively close friends, ordinary friends, and unfamiliar friends. The electronic device can learn the roles of each friend in the circle of friends based on the setting of the intimacy of the owner to the friend. If a family member clicks the photo through the circle of friends and wants to watch it, the electronic device will know the role of the person who clicked the photo in the owner's circle of friends, which is a family member, and can display the entire photo to the family member. If a friend with a general relationship clicks on the photo through a circle of friends and wants to watch it, the electronic device will know the role of the person who clicked the photo in the owner's circle of friends. The rest of the image in the entire photo, except for the license plate number and emblem, is shown to the friend.

Wherein, different roles of the viewing object need to be bound in advance correspondingly to the content parts that the viewing objects belonging to different roles should watch in the photo, so that the image content that the viewing object should watch can be determined based on the role of the viewing object.

The photos published in the circle of friends can be face photos. As a special kind of private photos, face photos can also display different image content according to the intimacy of the person who wants to view the face photos in the circle of friends and the owner. Exemplarily, if a family member clicks a face photo through a circle of friends and wants to watch it, the electronic device learns the role of the person who clicked the face photo in the owner's own circle of friends, who is a family member, and can then The face photo is displayed to the family in the display effect of the original photo (without beauty treatment). If a friend clicks a face photo through a circle of friends and wants to watch it, the electronic device will know the role of the person who clicked the face photo in the owner's circle of friends. The face photo is displayed to friends in general relationship as a beautified photo. Wherein, different characters of the viewing object may be bound in advance correspondingly to the images of the display effect when viewing objects belonging to different roles in the photo are viewing the photo. Wherein, different roles may be role identifiers set by the user of the electronic device or the user of the application program for different user IDs (identifications), such as family members, friends, and the like.

As can be seen from the foregoing, for privacy files, the technical solutions of the embodiments of the present application are used to display different contents of the privacy files according to the identity of the viewing object, or realize the display of the privacy files according to the location and/or time of the electronic device. Display of different content.
