Pindrop® Protect provides a risk score and call intelligence to the call center in the first few seconds of each call. The risk score — along with the analysis of the caller’s voice, device, and behavior — is provided to the call center’s fraud analyst team for further investigation. Pindrop’s proprietary machine learning algorithms then use feedback from the investigation to maximize solution performance. Pindrop® Passport evaluates call center interactions in real-time to passively authenticate legitimate customers. Passport runs in the background of every call, combining patented Phoneprinting™ technology with proprietary Deep Voice™ biometrics to determine if a caller has the right device, voice, and behavior to access an account. Whether callers use voice or touch-tone interactions within the IVR — or opt to speak to an agent — Pindrop credentials follow customers across the lifecycle of each call.
