Facial Recognition Error Sees Shopper Ejected
5 Feb
Summary
- Customer wrongly identified by facial recognition software.
- Sainsbury's apologized and offered a £75 voucher.
- Human error, not the technology, caused the mistake.

A loyal Sainsbury's customer of ten years experienced a deeply humiliating ordeal when facial recognition software wrongly identified him as an offender. The 42-year-old man was escorted out of his local store in London by staff and security.
Sainsbury's has been trialing Facewatch technology in six London stores to combat rising theft and aggression, reporting a significant reduction in such incidents. The software boasts a 99.98 percent accuracy rate, aiming to proactively identify known criminals.
However, in this instance, the error occurred during the human verification stage. The customer, after being asked to leave, submitted a data request to Facewatch to understand the alert. Facewatch confirmed he was not on their database, redirecting Sainsbury's.
Both Sainsbury's and Facewatch stated the incident was due to human error, with staff approaching the wrong individual. This follows other reported cases of shoppers being wrongly flagged by similar systems, raising concerns about due process.
