Use the power of Voice Biometrics against fraud

Blacklist Identification

Detect fraudsters through passive verification

Blacklist Identification

Sestek Blacklist Identification is a voice biometric tool used by contact center fraud teams for fraud prevention and detection. Just like how fingerprints are used for identity verification, voice can also be used to protect against and solve crime.

After the system records a user voiceprint, the technology automatically crosschecks every call with the blacklist database to identify potential fraudsters.

It marks those calls that are scored higher than the threshold score and identifies listed fraudsters by their voices, comparing the captured voice with voiceprints stored in the blacklist voiceprint database. Thus, it detects fraudsters through passive verification and triggers alarms to fraud teams.
