...Ready For It? Taylor Swift Has Been Using Facial Recognition Technology At Her Concerts

Taylor Swift is not afraid of using facial recognition technology at her concert to stop troublemakers.

When you attend a Taylor Swift concert, you expect a reasonable level of security given the fact that tens of thousands of fans all pack into a stadium-like venue.

Bag checks? No worries. Security cameras checking for suspicious individuals? Okay, that's fine.

But, what if they were also scanning your face into a security database?

At a concert in California's Rose Bowl in mid-May, it was revealed that her security team was doing just that; scanning audiences' faces for security purposes.

Rolling Stone spoke to the chief security officer at the concert, Mike Downing, who told them what exactly was going on.

"Everybody who went by would stop and stare at [the screens], and the software would start working," Downing told Rolling Stone.

The screens were showing footage of her rehearsals, so naturally, fans were drawn to it while they were waiting.

Scans of their faces were then sent to a "command post" in Nashville where they were compared to list of known Swift stalkers.

Still, the majority of concert-goers (if not all) were unaware their faces were being scanned and analysed. It's also not entirely clear what happened to the data after the concert ended.

Earlier this year, Ticketmaster announced that they had invested in facial recognition technology to make security, access and identification checks when entering even faster. Essentially, your ticket would be linked to your face so you wouldn't have to scramble to find it at every checkpoint.
