setting the first entry to an unencrypted state when the biometric feature entered by the user matches the preset biometric feature.

6. The method according to claim 2 , wherein after displaying the encrypted content list and the unencrypted content list of the application, the method further comprises:

obtaining a second instruction entered by the user to open a second entry in the unencrypted content list;

presenting, according to the second instruction, content corresponding to the second entry;

obtaining, according to the second instruction, a biometric feature entered by the user; and

setting the second entry to an encrypted state when the biometric feature entered by the user matches the preset biometric feature.

7. The method according to claim 1 , wherein actively obtaining the biometric feature of the user further comprises:

obtaining information about a geographic location and an environment in which a mobile terminal is located; and

when the information about the geographic location in which the mobile terminal is located matches preset geographic location information or when the environment information matches preset environment information.

8. A mobile terminal privacy protection method, comprising:

obtaining an unlock instruction entered by a user on a lock screen interface;

actively obtaining a biometric feature of the user according to the unlock instruction; and

presenting an unlocked first interface when the obtained biometric feature of the user matches a preset biometric feature;

presenting a second unlocked interface when the obtained biometric feature of the user does not match the preset biometric feature,

wherein an interface element of the unlocked second interface comprises an unencrypted application icon,

wherein interface elements of the unlocked first interface comprise an encrypted application icon and the unencrypted application icon, and

wherein the encrypted application icon is an application icon that is not presented when the obtained biometric feature of the user does not match the preset biometric feature.

9. The mobile terminal privacy protection method according to claim 8 , wherein actively obtaining the biometric feature of the user further comprises:

obtaining information about a geographic location and an environment in which a mobile terminal is located; and

actively obtaining the biometric feature of the user according to an application start instruction when the information about the geographic location in which the mobile terminal is located matches preset geographic location information or when the environment information matches preset environment information.

10. A mobile terminal, comprising:

a processor configured to obtain an application start instruction;

an input device coupled to the processor and configured to actively obtain a biometric feature of a user according to the application start instruction; and

an output device coupled to the processor and the input device and configured to display an encrypted content list and an unencrypted content list of an application when the obtained biometric feature of the user matches a preset biometric feature,

wherein the encrypted content list of the application is generated according to encrypted content in the application,

wherein the unencrypted content list of the application is generated according to unencrypted content in the application, and

wherein the encrypted content in the application is content that is not presented when the obtained biometric feature of the user does not match the preset biometric feature,

wherein the processor is further configured to

obtain an unlock instruction entered by the user on a lock screen interface;

actively obtain the biometric feature of the user according to the unlock instruction;

display an encrypted application icon and an unencrypted application icon when the obtained biometric feature of the user matches the preset biometric feature; and

display the unencrypted application icon when the biometric feature of the user is not obtained and when the obtained biometric feature of the user does not match the preset biometric feature.

11. The mobile terminal according to claim 10 , wherein the input device is further configured to:

actively obtain a facial feature of the user;

the input device is further configured to actively obtain an eye iris feature of the user; or

the input device is further configured to actively obtain a fingerprint of the user.

12. The mobile terminal according to claim 10 , wherein the input device is further configured to actively obtain, using a touchscreen of the mobile terminal, a fingerprint entered by the user when operating the unencrypted content list, and wherein the output device is further configured to display the encrypted content list and the unencrypted content list of the application when the actively obtained fingerprint matches the preset biometric feature.
