Passive Liveness Detection and Analysis

SAFR’s passive liveness detection enhances security for face biometric authentication solutions. It adds detection and alerting capabilities when a printed photo or digital image or video is presented for identity authentication or physical access control workflows.


The SAFR algorithm uses a multi-faceted approach, analyzing texture and context, based entirely on the RGB visual spectrum field from a standard 2D COTS camera. Unlike the more costly approaches employed by most face recognition companies, which rely upon projected light, IR, or specialized stereoscopic / depth sensing cameras that are expensive, SAFR’s solution can be used to analyze video streams from IP camera embedded in an access control terminal, in kiosks and ATMs, built into an Android or iOS app, or an end-user’s USB or laptop camera.

Presentation attacks and spoofing attempts, such as a static image on paper or a mobile device displaying a static photo or video clip are successfully detected.
