Electronic device and unlocking method therefor

An electronic device comprising:

• at least one processor;
• a gyroscope electrically coupled to the processor;
• a capturing device electrically coupled to the processor;
• and
• a storage device electrically coupled to the processor and storing instructions for execution by the processor to cause the processor to:
• acquire, when the electronic device is locked, motion data of the electronic device as detected by the gyroscope at predetermined intervals;
• determine whether current motion of the electronic device is caused by a human, according to the acquired motion data and motion data pre-stored in the storage device;
• control, when determining that the current motion of the electronic device is caused by the human, a capturing device to capture an image of scene in front of the electronic device;
• acquire the image captured by the capturing device;
• determine whether any biological characteristics in the acquired image match with at least one biological characteristic pre-stored in the storage device;
• and
• control, when determining that the biological characteristics in the acquired image match with at least one biological characteristic pre-stored in the storage device, the electronic device to unlock.
