Abstract:
Disclosed is a mobile device to provide enhanced security based upon contextual sensor inputs. The mobile device may include: a biometric sensor; a contextual sensor; and a processor. The processor may be configured to: determine an authentication score based upon a biometric input received from the biometric sensor; modulate the authentication score based upon a contextual sensor input from the contextual sensor related to an event; and determine if the modulated authentication score falls below a predetermined threshold. If the authentication score falls below the predetermined threshold, the processor may command that a secondary authentication be performed or the destruction of a biometric template.

Abstract:
Techniques for improving the integrity and performance of biometric security processes on data processing devices are provided. An example of a method of determining a liveness of a biometric input according to the disclosure includes obtaining inquiry image information, obtaining enrollment image information, determining alignment information based on the inquiry image information and the enrollment image information, determining an overlap area based on the alignment information, determining anti-spoofing features based on the overlap area within the inquiry image information and the enrollment image information, and outputting a liveness score based on the anti-spoofing features.
