SYSTEMS AND METHODS FOR SPOOF DETECTION AND LIVENESS ANALYSIS

Spoof-detection and liveness analysis is performed using a software-based solution on a user device (102), such as a smartphone having a camera, audio output component (302) (e.g., earpiece), and audio input component (304) (e.g., microphone). One or more audio signals are emitted from the audio output component (302) of the user device (102), reflect off a target (104), and are received back at the audio input component (304) of the device. Based on the reflections, a determination (202) is made as to whether the target (104) is comprised of a three-dimensional face-like structure and/or face-like tissue. Using at least this determination, a finding is made as to whether the target (104) is likely to be spoofed, rather than a legitimate, live person.
