As a part of his Ph.D. research at Georgia Institute of Technology, Vijay Balasubramaniyan was trying to find a solution to the most simple yet global problem- how to track the location of an unknown mobile number calling you? Based on technology developed in his research, he co-founded Pindrop Security with Paul Judge. A security solutions company that uses “acoustic fingerprint: detection techniques to detect and stop phone-based fraud. Prior to starting his own company, Balasubramaniyan worked in various engineering and research roles with Google, Intel, Siemens and IBM research.


Key Goal

One of the biggest challenge faced by financial services companies is the dependency on caller ID alone to ensure the legitimate identity of callers availing transaction-based services. However, with the advent of technology spoofing caller ID is a child’s play, raising a major security concern. Several large companies are meeting these security issues with voiceprints capture and tracking the numbers in a list, but those efforts get wasted with frauds using devices to change their voices. To combat such problems, Pindrop Security employs its phone printing process that can decipher the tiniest details of a phone call like audio cutoff frequency and trace the fraud calls.
