Optionally, in other possible implementation manners of the present invention, the terminal may also read the fingerprint information when the user touches the touch screen at a specific location of the preset interface.

It can be understood that when the touch operation performed on the touch screen by the user on the preset interface may be a pressing operation, the fingerprint information when the pressing operation is received may correctly recognize the fingerprint of the user, and the user touches the touch screen on the preset interface. When the touch operation is performed as a sliding operation, the fingerprint information of the user touching the preset interface at the start of the sliding moment can correctly identify the fingerprint of the user.

Optionally, in some possible implementation manners of the present invention, the method further includes:

In the process of generating the preset information, no encryption processing is performed on the preset information.

For example, in some possible implementation manners of the present invention, when a photo is generated by taking a photo with a mobile phone and the photo is stored in a mobile phone photo album, no photo encryption processing is performed on the photo stored in the mobile phone photo album, only in subsequent users. When a specific photo in the mobile phone album is read, if the fingerprint information when the user touches the touch screen does not match the preset fingerprint information, the specific photo is encrypted, so that the calculation amount is small and the efficiency is high.

It can be understood that if the information is encrypted in the process of information generation, all the information needs to be encrypted, and when any information is read, the decryption is required accordingly, resulting in a large amount of calculation. The system overhead is large; in the process of information generation, the information is not encrypted, and only when the user reads the preset information, when the fingerprint information of the user touches the touch screen does not match the preset fingerprint information, only the user needs The preset information of the access is encrypted, and the encrypted preset information is only a part of the total information, and the amount of data is small, so that the calculation amount is small, the system overhead is small, and the efficiency is high.

If the fingerprint information matches the preset fingerprint information, the preset information is displayed.

When the preset information is specific data, if the fingerprint information matches the preset fingerprint information, the preset information is displayed.

For example, in some possible implementation manners of the present invention, if the preset information is a private album in the mobile phone album application, since the photo is not encrypted during the generation of the photo in the private album, the viewing is performed. The private photo album, and the fingerprint information when the user touches the touch screen matches the preset fingerprint information, can be directly viewed without decrypting the private album, that is, the mobile phone directly displays the private album to the user.

When the preset information is a specific application, if the fingerprint information matches the preset fingerprint information, the preset information is accessed.

For example, in some possible implementation manners of the present invention, if the preset information is a mobile phone photo album application, since the mobile phone photo album application is not encrypted during the initial setting, when the mobile phone photo album application is accessed, and the user touches the touch screen, When the fingerprint information matches the preset fingerprint information, you can directly enter the mobile phone album.

It can be understood that specific data is not encrypted during the specific data generation process, and the specific application is initially When the initial setting is not encrypted for a specific application, when a user with access rights subsequently accesses, the specific data or a specific application need not be decrypted to directly view specific data or access a specific application, and the system overhead is small and the operation is convenient. .

Optionally, in some possible implementation manners of the present invention, if the fingerprint information does not match the preset fingerprint information, encrypting and/or hiding the preset information, or shielding the After the touch operation, the method further includes:

If the preset fingerprint information is obtained again, the preset information is decrypted and/or displayed.

The protection of the preset information, because the touch operation is blocked, the touch operation is temporarily blocked on the preset interface, and when the preset interface is accessed again, the fingerprint information when the user touches the touch screen is continuously obtained, thereby When the preset fingerprint information is obtained, the preset information is presented to the authorized user, and the access of the authorized user to the preset information is realized.

Optionally, in another possible implementation manner of the present invention, when the preset information is specific data, if the fingerprint information does not match the preset fingerprint information, the preset is After the information is encrypted and/or hidden, or the touch operation is blocked, the method further includes:

If the preset fingerprint is obtained again, the preset information is decrypted and/or displayed. Optionally, in some possible implementation manners of the present invention, when the specific data is previously encrypted, the specific data is decrypted when the preset fingerprint information is acquired again, and when the specific data is previously hidden, When the preset fingerprint information is acquired again, the specific data is displayed. When the specific data is previously encrypted and hidden, the specific data is displayed and decrypted when the preset fingerprint information is acquired again.

For example, in some possible implementation manners of the present invention, if the fingerprint information when the user touches the touch screen is not the preset fingerprint information when accessing a certain private file in the mobile phone, the private file is performed. The encryption process is performed, so that the user cannot access the private file. When the fingerprint information when the touch screen is touched by the user is the preset fingerprint information, the private file is decrypted, so that the user can access the private file.

Optionally, in another possible implementation manner of the present invention, when the preset information is a specific application, if the fingerprint information does not match the preset fingerprint information, the preset is After the information is encrypted and/or hidden, or the touch operation is blocked, the method further includes:

If the preset fingerprint information is obtained again, the preset information is decrypted and/or allowed to be accessed. The preset information.

Optionally, in some possible implementation manners of the present invention, when the specific application is previously encrypted, when the re-acquired fingerprint information matches the preset fingerprint information, the specific application is decrypted. When the obtained fingerprint information does not match the preset fingerprint information, the user enters the specific application, and when the acquired fingerprint information matches the preset fingerprint information, the specific application is allowed to enter.

For example, in some possible implementation manners of the present invention, when accessing the mobile phone photo album, when the fingerprint information of the unprivileged user touching the touch screen is not the preset fingerprint information, the mobile phone photo album is exited when When the fingerprint information of the authorized user touches the touch screen is the preset fingerprint information, the user is allowed to enter the mobile phone album.

In order to facilitate the better understanding and implementation of the foregoing solutions of the embodiments of the present invention, the following is exemplified in conjunction with some specific application scenarios.

Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of another data encryption method according to another embodiment of the present invention, wherein another data encryption method provided by another embodiment of the present invention is shown in FIG. Can include:

S201. Acquire fingerprint information when the user touches the touch screen on the preset interface, and the preset interface is an access interface of the preset information.

Optionally, in some possible implementation manners of the present invention, the preset interface sets an access interface of the preset information as a preset interface according to a user's needs, so that the user enters the response through the preset interface. When using or data, the terminal recognizes the fingerprint information when the user touches the touch screen through the touch screen in real time.

Optionally, in some possible implementation manners of the present invention, the terminal installs the fingerprint sensor under the screen, so that the terminal can read the fingerprint information when the user touches the touch screen at any position on the user touch the preset interface screen, which is convenient. User action.

S202. Determine whether the fingerprint information matches the preset fingerprint information.

Optionally, in some possible implementation manners of the present invention, the preset fingerprint information may be one, so that the received fingerprint information input by the user only needs to be compared with the preset fingerprint information, and the user touch is determined. Whether the fingerprint information when the touch screen matches the preset fingerprint information.

S203. If the fingerprint information does not match the preset fingerprint information, encrypt and/or hide the preset information, or mask the touch operation.

For example, in another possible implementation manner of the present invention, when the user who has access rights to a specific album in the mobile phone photo album application is Zhang San, the preset fingerprint information is set as the fingerprint of Zhang San, then When the fingerprint information is received on the access interface of the specific album, the fingerprint information is compared with the preset fingerprint of the third album. If the fingerprint is not matched, the specific album is encrypted and hidden, or the touch operation is blocked. To temporarily disable the touch operation.

For example, in some possible implementation manners of the present invention, when the preset information is a specific application, taking the mobile phone photo album application as an example, when the fingerprint information of the user touching the touch screen does not match the preset fingerprint information, The mobile phone photo album application can be encrypted. In this case, the user needs to input a password to enter, and the user can be terminated to access the mobile phone photo album, or the touch operation performed by the user on the touch screen is shielded at this time, so that the touch operation is temporarily disabled, thereby achieving Privacy protection for mobile photo album applications.

It can be understood that when the preset information is specific data, if the fingerprint information when the user touches the touch screen does not match the preset fingerprint information, the specific data is encrypted and/or hidden, or the user is touched. The touch operation performed by the touch screen temporarily disables the touch operation, and prevents the user from continuing to access specific data, thereby realizing protection of specific data; when the preset information is a specific application, if the user touches the touch screen, the fingerprint information and When the preset fingerprint information does not match, the specific application is encrypted and/or the user is allowed to continue to access the application, or the touch operation performed by the user on the touch screen is blocked, so that the touch operation is temporarily disabled, and the privacy protection for the specific application is realized. And because only specific data or specific applications are encrypted, rather than encrypting all the data, the amount of calculation is small.

S204. If the preset fingerprint information is received, the preset information is displayed.

It can be understood that, when the command information when the user touches the touch screen is not the preset fingerprint information, the preset information is encrypted or the touch operation is blocked, so that the user cannot view the preset information. The protection of the preset information, because the touch operation is blocked, the touch operation is temporarily blocked on the preset interface, and when the preset interface is accessed again, the fingerprint information when the user touches the touch screen is continuously obtained, thereby When the preset fingerprint information is obtained, the preset information is presented to The privileged user realizes the access of the authorized user to the preset information.

If the preset fingerprint information is obtained again, the preset information is decrypted and/or the preset information is allowed to be accessed.

It can be understood that, when the specific data generation process does not encrypt the specific data, and the specific application is not set to be encrypted when the specific application is initially set, the specific data or the specific application does not need to be decrypted when the user with subsequent access rights accesses. You can view specific data directly or access specific applications, with low system overhead and easy operation.

It can be seen that, in the solution of the embodiment, the fingerprint information of the touch operation performed by the user on the touch screen is obtained on the preset interface, and the preset interface refers to the access interface of the preset information; determining the fingerprint information and the preset fingerprint Whether the information is matched or not; if the fingerprint information does not match the preset fingerprint information, the preset information is encrypted and/or hidden, or the touch operation is blocked, so that the touch operation is temporarily disabled. Therefore, when the fingerprint information obtained by the user on the preset interface does not match the fingerprint information of the touch screen, only the preset information is encrypted, the calculation amount is small, the system overhead is small, and the efficiency is high. .

Let's take a more specific application scenario below.

For example, when the user takes a photo, the mobile phone photo album is not encrypted. If the mobile phone photo album is to be securely controlled, the mobile phone photo album needs to be set as an application that needs to be accessed by fingerprint recognition, and the mobile phone photo album owner's fingerprint is set to the mobile phone photo album. For the preset fingerprint, when all the users who use the mobile phone access the album in the access interface of the album, when the user presses the screen of the mobile phone At any location, the fingerprint sensor will sense the user's fingerprint and identify the fingerprint. Firstly, when the mobile phone owner accesses the mobile phone photo album, the fingerprint information of the mobile phone owner pressing the mobile phone screen can be recognized as the preset fingerprint information, and the mobile phone owner can directly enter the mobile phone photo album, so that the mobile phone owner does not need to perform the mobile phone photo album when accessing the mobile phone photo album. Any encryption and decryption processing can be accessed, the operation is convenient, and the system overhead is small. When other users want to access the album, the fingerprint information when the user presses the screen of the mobile phone is not the preset fingerprint information, encrypts the mobile phone album, and terminates the user accessing the mobile phone album, and temporarily makes the user in the interface. The operation of the touch screen is invalid, and the touch operation is restored when the user interface is re-entered the next time, thereby realizing the encryption protection of the mobile phone album.

Further, when the mobile phone owner accesses the mobile phone album again, the mobile phone again recognizes the fingerprint information when the mobile phone owner presses the touch screen, determines that the fingerprint information is consistent with the preset fingerprint information, re-decrypts the mobile phone photo album, and allows the mobile phone owner to access the photo album.
