Systems and methods for detecting a call anomaly using biometric identification

摘要

Embodiments of the present invention are directed generally to use of biometric identification during a call for detecting an anomaly occurring in the call, such as a change in the parties participating on the call. Communication between parties of a call is monitored and biometric identification is performed using the communication. According to one exemplary embodiment, biometric prints, such as voice prints, face prints, etc., are obtained for parties that are authorized to participate on a call. The call is then monitored and biometric data (e.g., audio, video, etc.) captured from communication during the call is compared with the biometric prints of the authorized parties to detect changes in the parties participating on the call, such as a new, unauthorized party joining the call. Thus, a call processing system can detect anomalies occurring during monitored calls, such as three-way calling, a handoff of a call, etc.

1. A method, comprising:
initiating a call between an inmate and another party via a call processing system, wherein the inmate and the other party are both allowed to participate in the call; continuously monitoring biometric voice prints during the call in real-time using the call processing system; determining, using the call processing system and based at least in part upon the monitored biometric voice prints, that a handoff event has taken place while the call is ongoing; and in response to the determination, initiating one of a plurality of different responsive actions via the call processing system, the actions selected from a group consisting of: terminating the call, recording the call, recording the event, notifying at least one party to the call, and notifying correctional facility personnel.
