Essex Police Pause Live Facial Recognition Technology Amid Bias Concerns

Essex Police have suspended the use of live facial recognition (LFR) technology following a study that indicated a significant bias in the system's targeting of black individuals compared to other ethnicities. The Information Commissioner’s Office (ICO) disclosed this decision, highlighting potential accuracy and bias risks associated with LFR systems, which have been deployed by at least 13 police forces across England and Wales, including London, Greater Manchester, and West Yorkshire.

The study, commissioned by Essex Police and conducted by academics from the University of Cambridge, involved 188 actors passing by cameras mounted on police vans in Chelmsford. Results revealed that while the system correctly identified about half of the individuals on a watchlist, it was statistically more likely to accurately identify black participants than those from other ethnic groups. Dr. Matt Bland, a criminologist involved in the study, emphasized the implications of these findings, stating, “If you’re an offender passing facial recognition cameras... the chances of being identified as being on a police watchlist are greater if you’re black.”

The ICO's report raised concerns about fairness and the need for ongoing monitoring of LFR technology. The Home Office previously announced plans to increase the number of LFR vans available to police forces five-fold, with 50 vans set to be deployed across England and Wales. Despite the suspension, the Home Office reported that LFR cameras in London led to over 1,300 arrests for serious crimes between January 2024 and September 2025.

Critics of the technology, including Jake Hurfurt from Big Brother Watch, have expressed alarm over the findings, asserting that “AI surveillance that is experimental, untested, inaccurate or potentially biased has no place on our streets.” This sentiment reflects a growing concern regarding the ethical implications of deploying such technologies without adequate safeguards.

A separate study conducted by the National Physical Laboratory indicated that while black men were most likely to be correctly matched by the LFR system, the results were not statistically significant. This discrepancy raises questions about the reliability of LFR technology and the varying interpretations of its effectiveness across different studies.

The suspension of LFR technology by Essex Police underscores the critical need for further investigation into the biases inherent in AI surveillance systems and their implications for public safety and civil liberties.
