Reportedly, Taylor Swift's security team installed facial recognition technology at a kiosk playing rehearsal footage outside one of her concerts. When people stopped to watch the footage, the facial scanner sent data to a control center in Nashville, where the faces in the crowd were checked against a database of Swift's known stalkers.
The technology was clearly used for a good cause in this case, and could be used in the future to prevent attacks like the fatal shooting of musician Christina Grimmie at a concert in 2016. Additionally, the technology is used at venues in places such as Japan for years. However, many Americans are concerned about the intersection of privacy and security, especially since this is a gray area in American law. For example, there are no clear answers about who owns the data that was recorded at Swift's concert, which could potentially be monetized (i.e. a company might pay to know who was at the concert, who drank what, who ate what, who was with who, etc.). Also, since concerts are private events, the taking of images from the crowd, without consent, is currently legal.
What do you think? Is this technology a good way to keep us safe, or is the lack of regulation surrounding it too much of a concern?
