Abstract

A method for protecting privacy information in a mobile terminal, including: granting, by the mobile terminal, user access according to an operation of a user, the granted access corresponding to the operation; enabling, by the mobile terminal, a protection mechanism set for the privacy information to be effective if the granted access includes access to the privacy information; and disabling, by the mobile terminal, the protection mechanism set for the privacy information to be ineffective if the granted access does not include access to the privacy information.

Claims

1. A method for protecting privacy information in a mobile terminal, comprising:

granting, by the mobile terminal, user access according to an operation of a user, the granted access corresponding to the operation;

enabling, by the mobile terminal, a protection mechanism set for the privacy information to be effective if the granted access includes access to the privacy information; and

disabling, by the mobile terminal, the protection mechanism set for the privacy information to be ineffective if the granted access does not include access to the privacy information.

2. The method according to claim 1, wherein the granting of user access comprises:

determining an access mode according to a system level password inputted by the user;

determining that the access to be granted includes access to the privacy information if the determined access mode is an owner mode; and

determining that the access to be granted does not include access to the privacy information if the determined access mode is a guest mode.

3. The method according to claim 1, wherein the granting of user access comprises:

determining an access mode according to a state of a preset switch for opening or closing a guest mode;

determining that the access to be granted includes access to the privacy information if the determined access mode is an owner mode; and

determining that the access to be granted does not include access to the privacy information if the determined access mode is the guest mode.

4. The method according to claim 2, after enabling the protection mechanism set for the privacy information to be effective, further comprising:

receiving an access request of the user on a preset item in the privacy information, and reminding the user to carry out identity authentication; and

determining whether or not to grant access to the preset item in the privacy information according to a result of the identity authentication.

5. The method according to claim 3, after enabling the protection mechanism set for the privacy information to be effective, further comprising:

receiving an access request of the user on a preset item in the privacy information, and, and reminding the user to carry out identity authentication; and

determining whether or not to grant access to the preset item in the privacy information according to a result of the identity authentication.

6. A non-transitory medium including instructions, executable by a processor in a mobile terminal, for performing a method for protecting privacy information in the mobile terminal, the method comprising:

granting, by the mobile terminal, user access according to an operation of a user, the granted access corresponding to the operation;

enabling, by the mobile terminal, a protection mechanism set for the privacy information to be effective if the granted access includes access to the privacy information; and

disabling, by the mobile terminal, the protection mechanism set for the privacy information to be ineffective if the granted access does not include access to the privacy information.

7. The non-transitory medium according to claim 6, wherein the granting of user access comprises:

determining an access mode according to a system level password inputted by the user;

determining that the access to be granted includes access to the privacy information if the determined access mode is an owner mode; and

determining that the access to be granted does not include access to the privacy information if the determined access mode is a guest mode.

8. The non-transitory medium according to claim 6, wherein the granting of user access comprises:

determining an access mode according to a state of a preset switch for opening or closing a guest mode;

determining that the access to be granted includes access to the privacy information if the determined access mode is an owner mode; and

determining that the access to be granted does not include access to the privacy information if the determined access mode is the guest mode.

9. The non-transitory medium according to claim 7, after enabling the protection mechanism set for the privacy information to be effective, the method further comprising:

receiving an access request of the user on a preset item in the privacy information, and reminding the user to carry out identity authentication; and

determining whether or not to grant access to the preset item in the privacy information according to a result of the identity authentication.

10. The non-transitory medium according to claim 8, after enabling the protection mechanism set for the privacy information to be effective, the method further comprising:

receiving an access request of the user on a preset item in the privacy information, and, and reminding the user to carry out identity authentication; and

determining whether or not to grant access to the preset item in the privacy information according to a result of the identity authentication.

11. A mobile terminal, comprising:

a processor; and

a memory for storing privacy information;

wherein the processor is configured to;

grant user access according to an operation of a user, the granted access corresponding to the operation;

enable a protection mechanism set for the privacy information to be effective if the granted access includes access to the privacy information; and

disable the protection mechanism set for the privacy information to be ineffective if the granted access does not include access to the privacy information.

12. The mobile terminal according to claim 11, wherein the processor is further configured to:

determine an access mode according to a system level password inputted by the user;

determine that the access to be granted includes access to the privacy information if the determined access mode is an owner mode; and

determine that the access to be granted does not include access to the privacy information if the determined access mode is a guest mode.

13. The mobile terminal according to claim 11, wherein the processor is further configured to:

determine an access mode according to a state of a preset switch for opening or closing a guest mode;

determine that the access to be granted includes access to the privacy information if the determined access mode is an owner mode; and

determine that the access to be granted does not include access to the privacy information if the determined access mode is the guest mode.

14. The mobile terminal according to claim 12, wherein the processor is further configured to:

receive an access request of the user on a preset item in the privacy information and remind the user to carry out identity authentication; and

determine whether or not to grant access to the preset item in the privacy information according to a result of the identity authentication.

15. The mobile terminal according to claim 13, wherein the processor is further configured to:

receive an access request of the user on a preset item in the privacy information, and remind the user to carry out identity authentication; and

determine whether or not to grant access to the preset item in the privacy information according to a result of the identity authentication.
