Abstract

A screen unlocking method, device and terminal, wherein the method includes: a first terminal sending a key information acquisition message to a second terminal, wherein the key information is used to unlock the first terminal; and the first terminal unlocking the screen of the first terminal according to the key information from the second terminal. By using the embodiment of the present document, it solves the problem that, when the screen cannot be unlocked since the user forgets the password, the version needs to be upgraded to unlock the screen, resulting in a waste of time and a loss of important data in the terminal caused by upgrading the version, the user can unlock the terminal according to standby key information, thus avoiding the situation in which the terminal cannot be unlocked since the unlocking code of the terminal is forgotten, and further improving the ease for using the terminal.

Claims

1. A screen unlocking method, comprising:

a first terminal sending a key information acquisition message to a second terminal, wherein the key information is used to unlock the first terminal;

the first terminal unlocking a screen of the first terminal according to the key information from the second terminal.

3. The method of claim 1, wherein, the first terminal unlocking the screen of the first terminal according to the key information from the second terminal comprises:

the first terminal judging whether the key information from the second terminal matches with key information stored in the first terminal or not;

if yes, unlocking the screen of the first terminal.

4. The method of claim 3, wherein, after the screen of the first terminal is unlocked successfully, the method further comprises:

a unlocking password of the first terminal being reset back to a no-password state.

5. The method of claim 1, further comprising:

encrypting and sending the key information acquisition message to the second terminal;

decrypting the key information from the second terminal, then judging whether the decrypted key information matches with the key information stored within the first terminal or not; and

if yes, unlocking the screen of the first terminal.

2. The method of clam 1, wherein, the first terminal sending the key information acquisition message to the second terminal comprises:

the first terminal judging whether a current number of unlocking times reaches a preset number of unlocking times or not;

if yes, sending the key information acquisition message to the second terminal.

6. A screen unlocking method, comprising:

after receiving a key information acquisition message from a first terminal, a second terminal prompting a user to input a verification code;

the second terminal receiving the verification code input by the user for obtaining the key information, and judging whether the verification code matches with a verification code preset in the second terminal or not;

if yes, sending the key information to the first terminal, wherein, the key information is used to unlock the first terminal.

7. The method of claim 6, wherein, the second terminal sending the key information to the first terminal comprises:

the second terminal taking out the key information previously stored in the second terminal and sending the key information to the first terminal according the key information acquisition message.

8. A screen unlocking device, located in a first terminal, and comprising:

a sending module, configured to send a key information acquisition message to a second terminal, wherein the key information is used to unlock the first terminal;

an unlocking module, configured to unlock the screen of the first terminal according to the key information from the second terminal.

9. The device of claim 8, wherein, the sending module comprises:

a first judging unit, configured to judge whether a current number of unlocking times reaches a preset number of unlocking times or not;

a sending unit, configured to send the key information acquisition message to the second terminal in the case that the current number of unlocking times reaches the preset number of unlocking times.

10. The device of claim 8, wherein, the unlocking module comprises:

a second judging unit, configured to judge whether the key information from the second terminal matches with the key information stored within the first terminal or not;

an unlocking unit, configured to unlock the screen of the first terminal in the case that they match.

11. A terminal, comprising:

the screen unlocking device of claim 8.

14. A terminal, comprising:

the screen unlocking device of claim 9.

15. A terminal, comprising:

the screen unlocking device of claim 10.

12. A terminal, comprising:

a receiving module, configured to prompt a user to input a verification code after receiving a key information acquisition message from a first terminal;

an authenticating module, configured to receive the verification code input by the user for obtaining the key information, judge whether the verification code matches with a verification code preset in the second terminal or not, and send a judgment result to a sending module;

the sending module, configured to send the key information to the first terminal if the judgment result is that they match, wherein the key information is used to unlock the first terminal.

13. The terminal of claim 12, wherein, the terminal further comprises:

a storing module, configured to pre-store the key information of the first terminal;

the sending module, configured to send the key information to the first terminal, comprising;

the sending module taking out the key information pre-stored in the storing module according to the key information acquisition message, and sending the key information to the first terminal.
