Poster: Image-synch: a liveness detection method based on ambient image

Traditionally, face recognition requires additional inconvenient human device interactions to verify users’ identity. In this poster, we introduce a novel authentication method, Imagesynch. It provides additional information by comparing reflection image from eyes and ambient image from different camera without human device interaction. Confined to the hardware capacity, We build simple prototypes and conduct experiments in the android system, providing empirical evidence that illustrates Image-synch is a robust authentication method. Furthermore, we discovered that it is possible to authenticate without any human device interactions, which indicates the potential of being widely used in future.
