Taylor Swift is using state-of-the-art technology to search for stalkers at a concert earlier this year.
Unbeknownst to her fans, many were secretly scanned inside a special kiosk using facial recognition technology at the Rose Bowl in Pasadena, California, in May.
The kiosk was showing exclusive rehearsal footage, but when fans stopped to watch, they had no idea they were secretly being photographed.
The images were then sent in real time from Pasadena to a “command post” in Nashville, Tennessee, where, using special software, they were cross-referenced against a database of known Swift stalkers.
Rodger Rodriguez of Vigilant Solutions showed Inside Edition how the technology works.
"[The] facial recognition system would have captured an image and searched it against a database, and it would have returned individuals who [it] would have thought ... closely resembled individuals placed on the watch list," he explained.
It is unknown if the technology has been used at other Swift gigs.
While the American Civil Liberties Union has expressed concerns about violations of privacy, the fine print on most concert tickets says you agree to be photographed.
Inside Edition reached out to Swift's representatives for comment but has not heard back.
