Abstract
Example systems and methods for defending against powerful, automated attacks on facial authentication systems are disclosed. A first verification is performed based at least in part on determining a response time for a response to a CAPTCHA or other challenge. In response to determining that the response time is within a threshold, a second verification is performed based at least in part on extracting a face feature or a voice feature from a plurality of samples associated with the response.
