Essex Police has put a stop to its deployment of live facial recognition (LFR) technology after a study revealed that the system was statistically more likely to identify Black individuals on a watchlist database. This decision comes as part of the police force’s commitment to address potential biases in its operations.
Study Findings Prompt Action
The research conducted by Cambridge University found that the Essex police system had a higher success rate in identifying men compared to women and was significantly more accurate in identifying Black participants than those from other ethnic groups. The study involved 188 volunteers acting as members of the public during a controlled field experiment, allowing researchers to accurately measure both correct and missed identifications.
False Positives and Racial Disparities
According to the study, the system correctly identified about half of the individuals on the watchlist who passed the cameras, with incorrect identifications being rare. However, of the six false positives recorded, four involved Black individuals. Given that Black subjects made up 23.8% of the sample, the researchers suggested that this imbalance was unlikely to be coincidental, although they cautioned that the limited number of false positives might not indicate a systematic bias.
Essex Police’s Response
In light of these findings, Essex Police decided to pause the use of LFR technology while collaborating with the algorithm software provider to review and update the system. A spokesperson for the police force noted that two independent studies had been commissioned, one indicating potential bias in identification rates and the other finding no statistically relevant bias. Following these assessments, the police force has revised its policies and procedures, expressing confidence in resuming the use of LFR technology for tracing and arresting wanted criminals.
Government Plans for Increased LFR Usage
Earlier this year, the British government announced plans to enhance the use of LFR and artificial intelligence in policing across England and Wales. The Home Office revealed intentions to fund 40 additional LFR-equipped vans, building on the ten already in operation. The government is set to invest over £26 million in a national facial recognition system and £11.6 million specifically for LFR capabilities, indicating a significant push towards integrating this technology into law enforcement.
