Abstract
A method for unlocking a display screen of an electronic device includes activating the display screen which is locked of the electronic device when receiving a communication signal from a key, and generating an unlocked icon on the display screen. A request is sent to the key for generating first audio information after the unlocked icon is pressed, and the first audio information of an unlock code is received from the key. When the first audio information is the same as second audio information generated by a decryption algorithm stored in the storage device of the electronic device, the display screen of the electronic device is unlocked.
Claims9
A key comprising:
- a storage device which stores a decryption algorithm;
- and
- a processor which converts an unlock code generated by executing the decryption algorithm to audio information, and sends the audio information to an electronic device to unlock the electronic device.
An electronic device comprises:
- at least one processor;
- and
- a storage device that stores one or more programs which, when executed by the at least one processor, cause the at least one processor to:
- activate a display screen of the electronic device which is locked when receiving a communication signal from a key, and generate an unlocked icon on the display screen;
- send a request to the key for generating an unlock code after the unlocked icon being pressed;
- receive first audio information of the unlock code from the key;
- determine whether the first audio information is the same as second audio information generated by the electronic device;
- and
- unlock the display screen of the electronic device when the first audio information is the same as the second audio information.
A computer-implemented method for unlocking a display screen of an electronic device using a key, being executed by at least one processor of the electronic device, the method comprising:
- activating a display screen of the electronic device which is locked when receiving a communication signal from a key, and generating an unlocked icon on the display screen;
- sending a request to the key for generating first audio information after the unlocked icon being clicked;
- receiving the first audio information of an unlock code from the key;
- determining whether the first audio information is the same as second audio information generated by a decryption algorithm stored in the storage device of the electronic device;
- and
- unlocking the display screen of the electronic device when the first audio information is the same as the second audio information.
