1. A system comprising:
- a processor; and
a memory coupled to the processor, the memory storing instructions which when executed by the processor causes the system to perform a method comprising;
maintaining a database of fraudster records for known fraudsters, each fraudster record including a voice signature and metadata associated therewith, the database of fraudster records comprising a plurality of segmented databases according to the metadata;
removing an inactive fraudster record from a segmented database after a predefined period; and
performing a screening operation to match a candidate and a known fraudster based on matching a voice signature and metadata for the candidate with a voice signature and metadata in the a fraudster record in the database.

7. A method, comprising:
-
collecting a voice sample and related metadata without regard to association of the voice sample and related metadata with fraud; creating a database of known fraudsters based on an association of metadata with fraud using an enrollment engine, the database including the collected voice sample and related metadata; removing the collected voice sample and related metadata from the database of known fraudsters after the collected voice sample or related metadata have not been matched during a period of time; receiving a candidate voice signature and metadata; comparing the received candidate voice signature and metadata for a match with the collected voice sample and related metadata using a screening engine; and assigning a score based on the comparison. - View Dependent Claims (8, 9, 10, 11, 12)

13. A system for detecting fraudsters comprising:
-
an audio capture device configured to collect voice samples; a database of known fraudster entries, each fraudster entry including a fraudster voice signature and metadata; an enrollment engine configured to remove an inactive fraudster entry from a first segmented database and search the remaining segmented databases to determine if the removed fraudster entry is active in a second segmented database; and a screening engine configured to search the database for a match of a candidate voice sample and metadata with a matching fraudster voice signature and metadata, and to assign a screening score based on the match. - View Dependent Claims (14, 15, 16, 17)

18. A method, comprising:
-
collecting a voice sample and related metadata without regard to association of the voice sample and related metadata with fraud; creating a database of known fraudsters based on an association of metadata with fraud using an enrollment engine, the database including the collected voice sample and related metadata; segmenting the database of known fraudsters into a plurality of segmented databases; determining if the collected voice sample and related metadata is inactive in a first segmented database; and searching the remaining databases to determine if the collected voice sample and related metadata is active in a second database; receiving a candidate voice signature and metadata; comparing the received candidate voice signature and metadata for a match with the collected voice sample and related metadata using a screening engine; and assigning a score based on the comparison.
