| Non-target document A | 234 | First memory address |
TABLE 1
Optionally, a target file and a plurality of non-target files may be stored in the same storage location, where the target file corresponds to a target password, and each non-target file corresponds to a non-target password; the association relationship between the file and the password and the storage location of the file can be shown in table 2:
| filename | Cipher code | File storage location |
| Object document | 123 | First memory address |
| Non-target document A | 234 | First memory address |
| Non-target file B | 345 | First memory address |
| Non-target file C | 456 | First memory address |
TABLE 2
Optionally, a target file and a plurality of non-target files may be stored in different storage locations, where the target file corresponds to a target password, each non-target file corresponds to a non-target password, and the password may point to a location where the file is stored; the association relationship between the file and the password and the storage location of the file can be shown in table 3:
| filename | Cipher code | File storage location |
| Object document | 123 | First memory address |
| Non-target document A | 234 | Second memory address |
| Non-target file B | 345 | The third storage address |

In the embodiment of the present invention, the number of the non-target files may be one or more, and when it is found from the preset association relationship that the decryption password currently input by the user is the non-target password, the non-target file corresponding to the non-target password is used as the first file corresponding to the decryption password currently input by the user. Different query modes are corresponding to one or more non-target files.
In an alternative of the embodiment of the invention, only one target file and one non-target file are stored. And the password corresponding to the non-target file in the association relationship is any non-target password.
Further, when the decryption password input by the user is determined to be a non-target password, the pre-stored non-target file is used as the first file corresponding to the decryption password currently input by the user.
Further, the first file is displayed on a display screen of the intelligent device. And the attribute information of the target file is modified to be hidden, so that other files under the folder are prevented from being displayed to the outside, the sizes of the attribute information of the folder for storing the target file and the non-target file are modified, and the modified folder size can be the same as the size of the displayed non-target file.
In another alternative of an embodiment of the present invention, one target file and a plurality of non-target files are stored in the same folder.
Further, when the decryption password input by the user is determined to be a non-target password, whether a non-target password identical to the decryption password currently input by the user exists in a plurality of preset non-target passwords is inquired, if the plurality of non-target passwords include the decryption password currently input by the user, a non-target file corresponding to the non-target password identical to the decryption password input by the user is searched according to the association relationship, and the searched non-target file is used as a first file corresponding to the decryption password currently input by the user. And modifying the attribute information of other non-target files and target files stored under the folder to be hidden, hiding all files, and modifying the size in the attribute information of the folder, wherein the modified folder size can be the same as the size of the displayed non-target files.
S24, when neither the target password nor the non-target password in the association relation contains the decryption password, randomly selecting a non-target file from the non-target files as a first file.
When the decryption password input by the user is determined to be the non-target password and the plurality of non-target passwords do not contain the decryption password currently input by the user, one non-target file can be randomly selected from the plurality of non-target files to be used as the first file to be displayed. And modifying the attribute information of other non-target files and target files stored under the folder to be hidden, hiding all files, and modifying the size in the attribute information of the folder, wherein the modified folder size can be the same as the size of the displayed non-target files.
Optionally, an alternative file may be stored, where the alternative file may be stored in a folder that is the same as the one target file and the plurality of non-target files, or may be stored in another folder, and when neither the target password nor the plurality of non-target passwords includes the decryption password currently input by the user, the alternative file may be displayed as the first file.
The file processing method provided by the embodiment of the invention receives the input decryption password of the file to be decrypted; inquiring a corresponding first file from a pre-stored association relationship between the password and the file; and displaying a first file corresponding to the decryption password. By the method, any decryption password has a corresponding display file, password error prompt is avoided, the effect of falseness and trueness is achieved, a person who wants to steal file information is prevented from cracking the password by trying the password for many times, and information safety is guaranteed.

The processor is used for executing the file processing program stored in the memory so as to realize the following steps of the file processing method executed on the intelligent device side:
receiving an input decryption password of a file to be decrypted; inquiring a corresponding first file from a pre-stored association relationship between the password and the file; and displaying a first file corresponding to the decryption password.
In one possible implementation manner, when the decryption password is determined to be a target password, a target file corresponding to the target password is inquired from the association relationship to serve as a first file; and when the decryption password is determined to be a non-target password, querying a non-target file corresponding to the non-target password from the association relation as a first file.
In one possible embodiment, when the decryption password is any one of the non-target passwords, the non-target file is used as the first file.
In one possible implementation, when the non-target password in the association relationship includes the decryption password, a non-target file corresponding to the decryption password is queried from a plurality of the non-target files as the first file.
In a possible embodiment, when neither the target password nor the non-target password in the association relationship includes the decryption password, a non-target file is randomly selected from the plurality of non-target files as the first file.
In a possible embodiment, when neither the target password nor the non-target password in the association relationship contains the decryption password, the candidate file is taken as the first file.
In one possible embodiment, the attributes of the non-target files and/or the alternate files are set to hidden.
In a possible implementation manner, when neither the target password nor the non-target password in the association relationship contains the decryption password, copying the target file to a preset position, changing part of content in the copied target file, and taking the changed target file as a second file; and displaying a second file corresponding to the decryption password.
