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 (11, 13) participating on the call. Communication between parties of a call (11, 13) is monitored and biometric identification is performed using the communication. According to one exemplary embodiment, biometric prints (105), such as voice prints (105A), face prints, etc., are obtained for parties (11, 13) that are authorized to participate on a call. The call is then monitored and biometric data (105) (e.g., audio, video, etc.) captured from communication during the call is compared with the biometric prints of the authorized parties (11, 13) to detect changes in the parties participating on the call, such as a new, unauthorized party joining the call. Thus, a call processing system (10) can detect anomalies occurring during monitored calls, such as three-way calling, a handoff of a call, etc. |
