Rite Aid's system scanned the faces of entering customers and looked for matches in a large database of suspected and confirmed shoplifters, the FTC said. When the system detected a match, it would flag store employees to closely watch the shopper. But the database included low-resolution images taken from grainy surveillance cameras and cellphones, undermining the quality of the matches, the FTC said. Those improper matches would then motivate employees to trail customers around the store or call the police, even if they’d seen no crime take place.
