London police facial recognition fails 4 out of 5 times

Facial recognition systems are used with increasing frequency already worldwide. They are also used by the police, like the police in London.

This analysis reveals that the London police facial recognition system is not working well. Since in four out of five cases, someone who is innocent is blamed for a crime. In fact, on many occasions, the system failed to obtain a final correspondence with a real person. These false positives were eventually lost in the crowd.

The police allege that the error rate is really lower, being one failure in every thousand recognitions. This is because they use a different metric. In your case, the number of times that you correctly associate any face with the corresponding individual.

Although if used as evidence in court, everything suggests that this London police facial recognition system would not be seen as valid. So there is clearly a lot of work to be done to improve this system. Since it is not normal to fail 80% of the time.
