Systems and methods are provided for recording a user's biometric features and generating an identifier representative of the user's biometric features and whether the user is alive (“liveness”) using mobile devices such as a smartphone. The systems and methods described herein enable a series of operations whereby a user using a mobile device can capture imagery of a user's face, eyes and periocular region. The mobile device is also configured analyze the imagery to identify and determine the position of low-level features spatially within the images and the changes in position of the low level features dynamically throughout the images. Using the spatial and dynamic information the mobile device is further configured to determine whether the user is alive and/or generate a biometric identifier characterizing the user's biometric features which can be used to authenticate the user by determining liveness and/or verify the user's identity.
