Abstract
The present teaching relates to method, system, medium, and implementations for detecting liveness. An input image is received with visual information claimed to represent a palm of a person. One or more variations of the input image are generated based on one or more models specifying conditions to generate the variations. The liveness of the visual information is detected based on the input image and the one or more variations thereof.
