About Phoneprinting™ Technology

New Technology to Prevent Fraud

Pindrop is the inventor and sole developer of Phoneprinting™ technology, a patented technology that analyzes phone calls to identify malicious behavior and verify legitimate callers. Phoneprinting™ technology is at the heart of Pindrop’s Call Center Anti-Fraud solutions, used by some of the largest banks, insurers, brokerages and retailers in the US to detect fraud and verify customers. In 30 seconds, Phoneprinting™ technology takes an audio call and breaks it down to over 1,000 unique call features to create a distinctive identifier for each caller.

Pindrop Phoneprinting™ technology reveals:

CALL TYPE: Is the caller using a cell, landline, or VoIP phone? Pindrop research indicates that 53% of fraudulent calls are made using a VoIP line, compared with only 7.2% of legitimate calls.

GEO LOCATION: Where is this call really coming from? Is it international or domestic? Does the location indicated by the call audio match the phone number reported by Caller ID?

UNIQUE PHONE: Has this caller been seen before? Fraudsters often change phone numbers, but it is much harder to change the audio characteristics that Pindrop uses to create a unique identifier for the calling device.

The Phoneprint is highly resilient – detecting the techniques fraudsters use to hide their true number or impersonate a legitimate caller. In addition, this technology identifies multiple callers associated with the same phoneprint, allowing enterprises to detect and track fraud rings. Phoneprinting™ technology is the only technology that can see through these attacker tactics.

Phoneprinting™ technology detects these fraud tactics:

CALLER ID SPOOFING: Callers deliberately falsify the telephone number or ANI relayed as part of the Caller ID information. There are hundreds of free phone apps that make it easy to spoof a phone number. Phoneprinting™ technology compares the information reported with Caller ID to the true device and location information to find anomalies that indicate spoofing.

VOICE DISTORTION: Criminals have many techniques for hiding their voice over the phone. Some may be good actors or fake a bad connection. Others use sophisticated voice distortion technology. Phoneprinting™ technology relies on the total audio of the call – much more than the sound of the voice alone.

SOCIAL ENGINEERING: Fraudsters are practiced in the art of manipulating people into giving up confidential information or breaking normal security procedures. Phoneprinting™ technology adds a layer of security that does not rely on what the caller is actually saying. Instead, it looks for risk factors in the information the caller can’t control.
