A person who is known to be an imposter, and is tracked in a fraudster watchlist. In most cases, there is a voiceprint for the fraudster. There can also be a deviceprint. Whenever the system verifies or identifies a caller, it compares the caller’s voice to the fraudster watchlist. See Detecting Fraud.
