Concert venues and organizers are turning to facial recognition solutions to identify security threats such as stalkers and important individuals who are to be treated as VIPs. Taylor Swift fans were unknowingly scanned at a kiosk that displayed rehearsal clips of the star at her Rose Bowl performance this year. The facial recognition software was able to identify potential security threats by sending images of concertgoers to a "Nashville "command post" where they were cross-referenced with a database of hundreds of the pop star's known stalkers." Ticketmaster has invested in facial recognition technology to scan concertgoers for the purpose of identifying VIPs and high rollers who will be able to pay a fee to avoid waiting in line at the turnstiles. "Everybody who went by would stop and stare at it, and the software would start working," says Downing, who attended the concert to witness a demo of the system as a guest of the company that manufactures the kiosks. Earlier this year, Ticketmaster invested in Blink Identity, a startup that claims its sensors can identify people walking past at full speed in about half a second. "It holds a lot of promise," says Justin Burleigh, Ticketmaster's chief product officer, adding that the company plans to beta-test the tech at venues early next year. "We're just being very careful about where and how we implement it."
