Abstract

A method for unlocking an electronic device is disclosed. The method includes: configuring, at the electronic device, a gesture password; storing, at the electronic device, the gesture password; detecting, at the electronic device, gestures on a touch screen of the electronic device when the electronic device is in a locked state; determining, at the electronic device, whether the detected gestures are consistent with the gesture password stored in the electronic device; and unlocking the electronic device if the detected gestures are consistent with the gesture password stored in the electronic device.

Claims

1. A method for unlocking an electronic device, comprising:

configuring, at the electronic device, a gesture password;

storing, at the electronic device, the gesture password;

detecting, at the electronic device, gestures on a touch screen of the electronic device when the electronic device is in a locked state;

determining, at the electronic device, whether the detected gestures are consistent with the gesture password; and

unlocking the electronic device if the detected gestures are consistent with the gesture password.

2. The method according to claim 1, further comprising:

encrypting, at the electronic device, the gesture password.

3. The method according to claim 1, wherein the gesture password comprises one or more time dependent static gestures, duration of each static gesture, and motion tail of each static gesture.

4. The method according to claim 1, wherein detecting gestures on the touch screen are performed within a predetermined time period.

5. The method according to claim 1, wherein detecting gestures on the touch screen comprises:

capturing, at the electronic device, a plurality of time dependent gesture images;

determining, at the electronic device, one or more static gestures contained in the gesture images by comparing an adjacent gesture images;

determining, at the electronic device, a duration of each of the one or more static gestures; and

determining, at the electronic device, a motion tail of each of the one or more static gestures by comparing the adjacent gesture images which contain a same static gesture.

6. An electronic device, comprising:

a touch screen for displaying at least one user interface;

a storage unit for storing instructions;

a processor for executing the instructions to perform a method, the method cause the processor to;

configure a gesture password;

store the gesture password;

detect gestures on a touch screen of the electronic device when the electronic device is in a locked state;

determine whether the detected gestures are consistent with the gesture password; and

unlock the electronic device if the detected gestures are consistent with the gesture password stored in the electronic device.

7. The device according to claim 6, wherein the method further cause the processor to:

encrypt the gesture password.

8. The device according to claim 6, wherein the gesture password comprises one or more time dependent static gestures, duration of each static gesture, and motion tail of each static gesture.

9. The device according to claim 6, wherein the detected gestures occur within a predetermined time period.

10. The device according to claim 6, wherein detecting gestures cause the processor to:

capture a plurality of time dependent gesture images;

determine one or more static gestures contained in the gesture images by comparing an adjacent gesture images;

determine a duration of each of the one or more static gestures; and

determine a motion tail of each of the one or more static gesture by comparing the adjacent gesture images which contain a same static gesture.
