German police recently completed testing a facial surveillance system. Two hundred frequent travelers volunteered to have their faces recorded and three different systems tried to recognize the faces in large public venue. Results (translated from German): 60% recognition at best, 30% on average (depending on light and other factors). While promising, these tests were conducted using outdated technology and drew criticism from the ACLU. Had more advanced technology been used, far better results would have been achieved.
