Consider what happens to criminals who write bad checks. Nowadays, a security camera can track someone who walks into a bank and take a sharp picture of the person's face. It can then compare that face to a database of known fraudsters. By the time the person walks up to the teller, the system can warn the teller not to cash a check from that person. This technology is available today thanks to San Francisco-based 3VR, which has applied its search technology to face recognition. Using off-the-shelf computers, the 3VR system captures an image of a face from a security camera and compares it to faces stored in a database. More than 90 percent of the time it comes up with an accurate match, according to the company. Three of the nation's top ten banks as well as the Bank of Hawaii are using it. Other customers are in retailing, travel and national security.
