Abstract
Protecting against an impersonation scam in a live video stream. In some embodiments, a method may include periodically extracting and storing signature features from verified video streams of verified streamers, identifying an unverified live video stream of an unverified streamer being viewed by one or more users, extracting and storing signature features from the unverified live video stream, computing overall distance scores between the signature features of the unverified live video stream and the signature features of the verified video streams, determining whether the unverified streamer is impersonating one or more of the verified streamers by determining whether one or more of the overall distance scores are less than a distance threshold, determining whether one or more text signature features of the unverified live video stream include an impersonation scam, and performing a remedial action to protect the one or more users from the impersonation scam.
