Electronic device and method for unlocking screen of electronic device
First Claim
1. A method comprising:
- detecting, in a screen-locked state, intent of a user to unlock a screen of an electronic device;
extracting contact information from a storage unit of the electronic device when detecting that the user intends to unlock the screen, wherein the contact information comprises a first attribute value and a second attribute value;
displaying the first attribute value on the screen;
prompting the user for an input;
detecting the input;
comparing the input to the second attribute value;
unlocking the screen when the input is the same as the second attribute value; and
maintaining the screen-locked state when the input is not the same as the second attribute value.

Abstract
An electronic device and a method for unlocking a screen of the electronic device are provided. The electronic device includes a screen and a storage unit. The method includes detecting, in a screen-locked state, intent of a user to unlock the screen; if it is detected that the user intends to unlock the screen, extracting contact information from the storage unit of the electronic device, where the extracted contact information includes a first attribute value and a second attribute value; displaying the first attribute value of the extracted contact information on the screen and prompting the user to input a second attribute value; and detecting an input of the user, and comparing the input of the user with the second attribute value; if the input of the user is the same as the second attribute value, unlocking the screen; and otherwise, maintaining the screen-locked state.

14. An electronic device, comprising:
-
a screen; a processor; and a memory coupled to the processor and comprising instructions that are used by the processor to implement the following; an action recognizing module configured to detect an intent of a user to unlock the screen; an information invoking module configured to extract contact information from the storage unit when detecting that the user intends to unlock the screen, wherein the contact information comprises a first attribute value and a second attribute value; a graph processing module configured to; display the first attribute value on the screen; and prompt the user for an input, wherein the action recognizing module is further configured to detect the input; a determining module configured to; compare the input to the second attribute value; and determine whether the input is the same as the second attribute value; and an executing module configured to; unlock the screen when the determining module determines that the input is the same as the second attribute value; and keep the electronic device in screen-locked state when the determining module determines that the input is not the same as the second attribute value. - View Dependent Claims (15, 16, 17, 18)
