TechRadar - Sainsbury's facial recognition returns to store that wrongly ejected innocent shopper
Sainsbury's has reinstated facial recognition technology at a store that previously used the system to wrongly identify and eject an innocent shopper. The return of the surveillance system has drawn attention from civil liberties group Big Brother Watch.
Why this matters: A store got it wrong once — ejected someone who had done nothing — and brought the same technology back anyway. That should tell you something about how much weight retailers give to false positives. Facial recognition in shops is not just a security tool. It runs on everyone who walks in, flags people before any wrongdoing, and can ruin someone's day or reputation based on a bad match. The person wrongly ejected last time had no say in being scanned and no easy way to fight back. That power imbalance does not go away just because the system is tuned.
