Specifically, fig. 2 is a flowchart illustrating a method for protecting a multimedia file according to an embodiment of the present invention. As shown in fig. 2, the multimedia file protection method is applied to an electronic device, wherein the multimedia file protection method includes:
step 020, receiving a multimedia file protection instruction when the multimedia file is in a browsing state;
the multimedia file comprises audio, video, photos, notebooks, notes, short messages and the like, and the electronic equipment can present the multimedia file on a screen, so that the multimedia function corresponding to the multimedia file is realized. For example, the electronic device presents a specific photo on the screen according to the selection of the user on the specific photo in the photo application program, and the electronic device presents a specific short message on the screen according to the selection of the user on the specific short message in the short message application program.
When the electronic equipment presents the multimedia file on the screen, the multimedia file is in a browsing state, and a user can browse a plurality of multimedia files based on the fact that the multimedia file is in the browsing state. In some states of freely browsing the multimedia file, when sharing the multimedia file, other users can freely select the multimedia file of the electronic device for viewing.
And when the electronic equipment detects that the multimedia application program corresponding to the multimedia file is in foreground operation, determining that the multimedia file is in a browsing state. For example, when the electronic device detects that the multimedia application running in the foreground is a photo application, the electronic device determines that the photo application is in a browsing state, and the user can browse photos in the photo application.
The multimedia file protection instruction comprises an instruction which is distributed by the electronic equipment according to related operations and used for executing the step of acquiring user identity information, and the electronic equipment executes corresponding events according to the multimedia file protection instruction. The related operation may be a soft operation or a hard operation, and the soft operation may be that the electronic device outputs a trigger signal according to a pre-logic to enable the electronic device to further distribute the multimedia file protection instruction. The hard operation may be an external operation on related hardware of the electronic device to cause the electronic device to issue a multimedia file protection instruction, for example, a touch operation performed by a user on a touch screen of the electronic device, an operation performed on a key of the electronic device, and the like.
And when the electronic equipment receives the multimedia file protection instruction, the execution of the next step is completed according to the preset logic.
022, obtaining user identity information according to the multimedia file protection instruction;
the user identity information is used for identifying the identity of the user, and may be a face image of the user, a fingerprint of the user, an iris of the user, a voice of the user, and the like.
The multimedia file protection instruction triggers the electronic equipment to enable the electronic equipment to acquire the user identity information. In the obtaining process, the electronic device can adopt a corresponding method according to the type of the user identity information to obtain the user identity information, wherein a designer can configure corresponding components and methods for the electronic device according to business requirements to obtain the user identity information.
And 024, if the user identity information does not match the pre-stored identity characteristic information, locking the currently browsed multimedia file.
The currently browsed multimedia file is a multimedia file of a multimedia application program running in the foreground of the electronic device, wherein "current" here is the current time point of the multimedia file being presented on the screen of the electronic device.
Wherein the identity information is used to evaluate whether a user currently using the electronic device is a desired user (the owner of the electronic device or a user trusted by the owner or a user specified by the owner).
The electronic equipment prestores identity characteristic information, when judging whether a user using the electronic equipment currently is an expected user, the electronic equipment calls the identity characteristic information, judges whether the identity information of the user using the electronic equipment currently is matched with the identity characteristic information, and does not lock a currently browsed multimedia file if the identity information of the user using the electronic equipment currently is matched with the identity characteristic information; and if not, locking the currently browsed multimedia file. When the multimedia file is in a locked state, other users cannot perform other operations on the multimedia file which do not conform to the preset logic. For example, when the currently browsed multimedia file is a photo, the operation is a switching operation for switching the current photo to the next photo, referring to fig. 1, when the user a hands the smartphone 10 to the user b, the smartphone 10 sets the current photo in a locked state, so that the smartphone 10 does not respond to the switching operation, that is, maintains the state of the current photo unchanged.
In this embodiment, when the user of the electronic device hands over the electronic device to another user, the electronic device locks the currently browsed multimedia file to prevent the other user from viewing the other multimedia file, so that the other multimedia file can be automatically protected from disclosure.
In some embodiments, the electronic device includes keys and/or a touch screen. The multimedia file protection instruction is triggered in response to the operation key. The key may be a volume down key or a volume up key or a power key. When the electronic equipment detects that the multimedia file is in a browsing state, a user operates the key, the key sends out a multimedia file protection instruction, and the electronic equipment receives the multimedia file protection instruction. In some embodiments, in order to distinguish that the key is in the normal functional state from the multimedia file is in the browsing state to distribute the multimedia file protection instruction, the electronic device counts the number of times of operation of the key within a preset time period, and when the electronic device detects that the number of times of operation of the key is greater than a preset threshold, the electronic device takes a trigger signal distributed from the key as the multimedia file protection instruction. And when the operation times are less than a preset threshold value, the electronic equipment takes the trigger signal sent from the key as a normal functional signal. For example, the user operates the volume-down key three times continuously, and the preset threshold is 2 times, and the electronic device uses the trigger signal sent from the key as a multimedia file protection instruction. When the user continuously operates the volume-down key 1 time, the electronic device uses the trigger signal emitted from the key as a signal for lowering the volume.
The difference from the above embodiment is that the multimedia file protection instruction is triggered in response to operating the touch screen. When the electronic equipment detects that the multimedia file is in a browsing state, a user operates the touch screen, and when the electronic equipment detects that the operation matches with a preset operation, the electronic equipment takes a trigger signal sent by the touch screen as a multimedia file protection instruction. When the electronic equipment detects that the operation does not match the preset operation, the electronic equipment takes the trigger signal sent from the touch screen as a normal touch signal. For example, the operation is a circle track, the preset operation is a "V" track, and the electronic device takes a trigger signal emitted from the touch screen as a normal touch signal. When the preset operation is a circle track, the electronic equipment takes the trigger signal sent from the touch screen as a multimedia file protection instruction.
In some embodiments, the electronic device further comprises a camera. The difference from the above embodiments is that step 022 comprises: and starting the camera to shoot the face image. When the electronic equipment detects a multimedia file protection instruction, a camera is started to shoot a face image of a user in front of the electronic equipment according to the multimedia file protection instruction. Therefore, the electronic equipment avoids high power consumption of the electronic equipment caused by frequent starting of the camera.
In some embodiments, the difference between the above embodiments is that step 022 comprises: a fingerprint of a touch operation performed on the touch screen is collected. In addition to the manner of acquiring the face image of the user by using the camera, please refer to fig. 1 again, when the user a hands the smartphone to the user b, the user b performs a touch operation on the touch screen where the currently browsed multimedia file is located, and the electronic device acquires the fingerprint of the user b of the touch operation performed on the touch screen. In some user use habits, the user b may want to view another multimedia file more, and then perform a touch switching operation on the touch screen, and in order to better solve the problem, the electronic device further locks the currently browsed multimedia file by collecting a fingerprint of the touch operation performed on the touch screen.
In some embodiments, the user identity information comprises a facial image and the identity feature information comprises facial features. As shown in fig. 3, the difference from the above embodiments is that step 024 includes:
0242, judging whether the face image shot by the camera matches the pre-stored face characteristics;
and 0244, if the face image shot by the camera does not match the prestored face characteristics, locking the currently browsed multimedia file.
And 0246, if the face image shot by the camera matches the pre-stored face characteristics, not locking the currently browsed multimedia file.
The electronic equipment can prestore one kind of face characteristics, and can prestore a plurality of kinds of face characteristics. For example, the electronic device may pre-store the face features of the owner of the electronic device, or pre-store the face features of the user specified by the owner of the electronic device in addition to the face features of the owner of the electronic device. The facial features are extracted from a plurality of facial images by a designer by collecting the facial images of a user according to an image processing algorithm, and the final facial features are formed.
In the process of judging whether the face image shot by the camera is matched with the prestored face features or not, the electronic equipment extracts face feature values from the face image shot by the camera by adopting an image processing algorithm, and locks the currently browsed multimedia file if the face feature values are not matched with the prestored face features. And if the face characteristic value is matched with the pre-stored face characteristic, the currently browsed multimedia file is not locked.
In some embodiments, the user identity information comprises a fingerprint and the identity information comprises fingerprint characteristics. As shown in fig. 4, the difference from the above embodiments is that step 024 includes:
0241, judging whether the collected fingerprint matches the pre-stored fingerprint characteristics;
0243, if the fingerprint does not match the preset fingerprint characteristics, locking the currently browsed multimedia file;
and 0245, if the fingerprint matches the preset fingerprint characteristics, not locking the currently browsed multimedia file.
The electronic equipment can prestore one kind of fingerprint characteristic, can prestore multiple fingerprint characteristic. For example, the electronic device may pre-store the fingerprint characteristics of the owner of the electronic device, and may also pre-store the fingerprint characteristics of the user specified by the owner of the electronic device in addition to the fingerprint characteristics of the owner of the electronic device. The fingerprint features are extracted from each finger according to a fingerprint identification algorithm by a designer by collecting the fingerprint features of each finger of the user, and the final fingerprint features are formed.
The electronic equipment judges whether the acquired fingerprint is matched with the pre-stored face characteristics or not, and locks the currently browsed multimedia file if the fingerprint is not matched with the preset fingerprint characteristics; and if the fingerprint matches the preset fingerprint characteristics, the currently browsed multimedia file is not locked.
In some embodiments, the electronic device may also hide multimedia files with a high level of security. As shown in fig. 5, the difference from the above embodiments is that after step 024, the multimedia file protection method further includes:
and 026, hiding the multimedia file with security protection.
The multimedia file with the security level protection is a multimedia file with a high security level. When the electronic equipment locks the currently browsed multimedia file, the multimedia file with security level protection can be hidden, so that the related important multimedia file of the owner of the electronic equipment or the multimedia file for recording the private content can be further hidden to maintain information security.
In some embodiments, as shown in fig. 6, the difference from the above embodiments is that step 026 includes:
0261, obtaining key field for describing multimedia file security level;
0263, if the acquired key field matches the preset contrast field, hiding the multimedia file corresponding to the key field;
0265, if the acquired key field does not match the preset contrast field, the multimedia file corresponding to the key field is presented.
The key field is used to describe the multimedia file security level, for example, the key field may be "security level 1" or "security level 2" or "highest security level" or "lowest security level" and so on.
The contrast field describes the security level of the multimedia file, which may be the highest security level or a range of security levels (security level 1 to security level 3). When the key field of the multimedia file is "security level 2", the multimedia file is hidden because the key field of the multimedia file matches a preset contrast field. When the key field of the multimedia file is "security level 5", the multimedia file is presented because the key field of the multimedia file does not match the preset contrast field.
In some embodiments, after step 024, the multimedia protection method further comprises:
the electronic equipment responds to the operation input by the user on the touch screen where the currently browsed multimedia file is located, and does not respond to the switching operation if the operation is the switching operation for indicating the switching of the multimedia file.
