Liveness detection for video calls

Abstract

As remote working has become more prevalent, video calls have become increasingly popular. However, various methods have been introduced to circumvent liveness in video calls, such as by playing a prerecorded video stream of a user; thus the user is not actually in attendance in the video call. Aspects of the present disclosure address this problem and others by detecting liveness in video calls. Some implementations can obtain biometric data from users during the video call to confirm that is user is indeed at the computing device streaming the video call. Some implementations can detect looping in the video stream of the user, such as by observing a repeated blinking pattern. Some implementations can prompt the user for a live response, such as by answering a question, and/or can determine that the user's behavior is inconsistent with the behavior of other users in the video call.
