Abstract
Technologies are provided for assessing liveness of a subject presented to a set of one or more cameras. A pair of face images captured during a first time period are respectively obtained from a first and a second camera. Information regarding each face image of the pair of face images is compared with each other to determine whether the pair of face images are consistent with each other. A third face image captured during a second time period is obtained from the first camera. A first face image of the pair of face images and the third face image are assessed to determine the presence of a particular variance between the first face image and the third face image. A result is provided regarding liveness of the subject presented based on the presence of the particular variance and the determination of consistency between the pair of face images.
