Method and apparatus for detecting liveness based on phase difference

A liveness detection apparatus based on a phase difference, the liveness detection apparatus comprising:

• a processor;
• and
• a memory comprising instructions executable by the processor,
• wherein in response to the instructions being executed by the processor, the processor is configured to:
• generate a first phase image based on first visual information of a first phase sensed by a first pixel group of a multiphase detection sensor;
• generate a second phase image based on second visual information of a second phase sensed by a second pixel group of the multiphase detection sensor;
• and
• detect a liveness based on a disparity between the first phase image and the second phase image.
