A Pindrop Security report The State of Phone Fraud 2014-2015: a Global, Cross-Industry Threat found that 86 million calls per month in the U.S. are phone scams. It also found that 1 in 6 phone numbers calling a consumer is a robocaller and 2.5 percent of U.S. phones receive at least one robocall per week.

The "acoustic fingerprinting" technology integrates with companies internal systems and identifies people's voices, locations, and devices. This is added to a database for future reference and to help separate legitimate callers from scammers.

To create metadata, Pindrop Security analyzed millions of phone calls in telecom databases from around the world and used machine learning to turn that information into usable content. By analyzing both the audio of a call and the metadata it has about a caller, the phoneprint reveals whether the caller is using a cell, landline, or VoIP phone; where the call really is coming from; and whether the caller has been seen before. It looks for evidence of frequency filters and codec artifacts, for example, and analyzes the calls for packet loss and dropped frames. In packet loss, "pindrop"-sized bits of audio drop out, which is where the company's name came from.

Based on the analysis, the service generates a risk profile and a score for each call. Analyzing millions of samples from call centers, it can identify specific criminal groups. An example is a criminal group based in Nigeria nicknamed "West Africa One." According to Pindrop, the West Africa One has 12 members and Pindrop has assessed the skill levels of each of the 12 members.
