detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In order to solve the problem of the security of the privacy information in the mobile terminal in the prior art, the embodiment of the present invention provides a method for protecting the privacy. The method is applied to the mobile terminal. As shown in FIG. 1 , the method includes:

101. Receive fingerprint information input by a user.

It can be understood that when the user uses the fingerprint to unlock, the fingerprint information is input, and the mobile terminal can perform subsequent steps according to the fingerprint information input by the user.

102. Determine a permission level corresponding to the fingerprint information.

The corresponding relationship between the fingerprint information and the privilege level is set in advance and stored in the mobile terminal. After receiving the fingerprint information input by the user, the mobile terminal identifies the fingerprint information, and further stores the fingerprint information and the privilege level from the mobile terminal. The correspondence relationship determines the permission level corresponding to the currently received fingerprint information.

The privilege level includes at least the highest privilege level, and the operation privilege corresponding to the highest privilege level is to allow operation on all information in the mobile terminal. For example, the mobile terminal may respond to a request by the user to open a private short message or a call record, and according to the user. The requested request displays private information such as a private message or call history.

It should be noted that the privilege level in the embodiment of the present invention may include only the highest privilege level and the common privilege level. The operation privilege corresponding to the common privilege level is: allowing non-private information in the mobile terminal to operate, but not allowing the mobile The private information in the terminal operates. Under the operation authority corresponding to the normal permission level, the mobile terminal hides the private information and does not respond to the received request for viewing the private information.

In another implementation manner, multiple privilege levels may be included in the embodiment of the present invention, for example, the highest level, the second level, and the third level. Each level of privilege level corresponds to a respective operation authority, starting from the highest level. The operation authority corresponding to each level of the privilege level is gradually weakened, or each level of privilege level corresponds to the operation authority of different types of applications in the mobile terminal, but only the operation authority corresponding to the highest privilege level allows the operation of the private information of the mobile terminal. .

It should be noted that, in the process of determining the privilege level corresponding to the fingerprint information, the mobile terminal identifies the fingerprint information, and when determining that the fingerprint information is legal fingerprint information, the mobile terminal successfully unlocks.

103. Set an operation right corresponding to the permission level.

After the privilege level corresponding to the received fingerprint information is determined in the foregoing step 102, the operation authority of the current mobile terminal is set as the operation authority corresponding to the privilege level.

104. When the non-operation time of the mobile terminal reaches the preset time, set the operation authority corresponding to the low privilege level, and the low privilege level is lower than the current privilege level.

It can be understood that, when the mobile terminal is not operated within a preset time, in order to prevent others from snooping on the private information in the mobile terminal, the mobile terminal automatically sets the operation authority to the operation authority corresponding to the low privilege level, and the low privilege level is lower than Current privilege level.

For example, the preset time may be 30 seconds. When the privilege level includes the highest privilege level and the normal privilege level, the current operation authority of the mobile terminal is the operation authority corresponding to the highest privilege level. If the mobile terminal is not operated in 30 seconds. , the mobile terminal will set the operation authority to the operation authority corresponding to the normal permission level.

The method for privacy protection provided by the embodiment of the present invention first receives fingerprint information input by a user, determines a permission level corresponding to the fingerprint information, and sets an operation authority corresponding to the permission level. When the non-operation time of the mobile terminal reaches a preset time, The operation authority corresponding to the low privilege level is set, and the low privilege level is lower than the current privilege level. Compared with the prior art, when the mobile terminal is in the unlocked state, the private information in the mobile terminal can be browsed by other people, resulting in the mobile terminal. Compared with the security information, the different fingerprint information in the embodiment of the present invention corresponds to different permission levels, and the mobile terminal sets the operation authority according to the permission level, so that only the user with the viewing privacy permission can view the privacy in the mobile terminal. The information, and when the non-operation time of the mobile terminal reaches the preset time, the mobile terminal reduces the operation authority, avoids the privacy information in the mobile terminal being snooped by others, and improves the security of the privacy information in the mobile terminal.

202. Set a permission level corresponding to the fingerprint information input by the user for the first time.

203. Set operation rights corresponding to each permission level.

It should be noted that when the user sets the privacy protection function of the mobile terminal for the first time, the user needs to input his own fingerprint information, and the mobile terminal sets the permission level corresponding to the fingerprint information to the highest privilege level, and sets the operation authority corresponding to the highest privilege level to Allows all information in the mobile terminal to operate.

After that, the mobile terminal can receive the operation permission corresponding to the highest privilege level. The other fingerprint information sets the permission level corresponding to the other fingerprint information according to the instruction input by the user on the setting interface of the mobile terminal.

It should be noted that, in the embodiment of the present invention, the execution order between the steps 201-202 and the step 203 is not limited, and multiple permission levels may be set in advance, and the operation authority corresponding to each permission level may be set, or in the above step 202. After the permission level corresponding to the fingerprint information input by the user is set, the operation authority corresponding to the permission level is set, which is not limited by the present invention.

204. Set an unlock password and a private password corresponding to the highest privilege level.

It can be understood that, when the user is inconvenient to unlock the fingerprint, or the mobile terminal cannot recognize the fingerprint information of the user, the mobile terminal can be unlocked by inputting a password. Therefore, the unlock password and the private password of the mobile terminal need to be set in advance.

The unlock password is used to unlock the mobile terminal, and the private password is used to determine whether the operation authority corresponding to the highest privilege level can be enabled.

Likewise, the present invention does not limit the order of execution between step 204 and steps 201-202 and step 203 above.

With the embodiment shown in FIG. 1 , after the mobile terminal receives the fingerprint information input by the user, the fingerprint information needs to be verified. FIG. 1 is a flow of the default fingerprint verification success, and the embodiment of the present invention also provides fingerprint verification. The execution flow after the failure, as shown in FIG. 3, after receiving the fingerprint information input by the user in the above step 101, the method further includes:

301. Verify the fingerprint information input by the user.

When the fingerprint verification is successful, step 102 is performed. When the fingerprint verification fails, step 302 is performed.

302. Prompt the user to input an unlock password.

303. Receive an unlock password input by the user, and verify the unlock password.

If the received unlock password is the same as the unlock password set in advance, the unlock password verification succeeds, and step 304 is performed; otherwise, the unlocking is refused, and no other operations are performed.

304. Prompt the user to input a private password.

305. Receive a private password input by the user. Verify the private password.

When the received private password is the same as the private password set in advance, the verification succeeds, and step 306 is performed; otherwise, the verification fails, and step 307 is performed.

306. Set the operation permission corresponding to the highest privilege level.

After setting the operation authority corresponding to the highest privilege level, all information in the mobile terminal can be displayed.

307. Set the operation permission corresponding to the secondary advanced permission level.

After the operation permission corresponding to the secondary advanced permission level is set, the private information of the mobile terminal is hidden, and only information other than the private information can be displayed.

It can be understood that when the privilege level includes only the highest privilege level and the normal privilege level, step 307 is to set the operation authority corresponding to the normal privilege level.

It should be noted that after

steps

306 and 307, step 104 needs to be performed.

In the privacy protection method provided by the embodiment of the present invention, when the user unlocks the mobile terminal by using the password, the private password still needs to be verified. Only after the private password is successfully verified, the mobile terminal is set to the highest level of the privilege level. The operation authority is that the user can view the private information in the mobile terminal only when the mobile terminal is in the operation authority corresponding to the highest level of the permission level. Therefore, if the private password verification fails, the private information in the mobile terminal cannot be viewed, and the mobile terminal is avoided. The privacy information is snooped by others, improving the security of private information in mobile terminals.
