Claim 0:
1. A voice biometric system for fraud prevention upscaling with a fraudster voice print watchlist, the voice biometric system comprising:
a hardware processor and a non-transitory computer readable medium operably coupled thereto, the non-transitory computer readable medium comprising a plurality of instructions stored in association therewith that are accessible to, and executable by, the hardware processor, to perform fraud prevention operations which comprise:
receiving a first voice print of a user during a voice authentication request;
accessing the fraudster voice print watchlist comprising voice print representatives for a plurality of voice print clusters each having one or more of a plurality of voice prints identified as fraudulent for the voice biometric system;
determining that one or more of the voice print representatives in the fraudster voice print watchlist meets or exceeds a first biometric threshold for risk detection of the first voice print during the fraud prevention operations;
determining whether the first voice print matches a first one of the plurality of voice print clusters based on a first similarity score between the first voice print and a representative of the first one of the plurality of voice print clusters; and
in response to determining that the first voice print matches the first one of the plurality of voice print clusters, determining that one of the plurality of voice prints in the first one of the plurality of voice print clusters matches the first voice print for the risk detection of the first voice print during the fraud prevention operations based on a second similarity score between the first voice print and the one of the plurality of voice print clusters.
