Failure in London. The system of face recognition in the subway recognizes nobody

Customers: London subway (London Underground)



Project date: 2018/12

At the end of December, 2018 it became clear that the system of face recognition developed in the London subway recognizes nobody. The London police officers are criticized for use of unmarked vans for check of disputable and inexact technologies of automatic face recognition at Christmas buyers.

The unrolled system of face recognition in the subway can scan up to 300 persons per second, comparing them with lists of the crimes suspected of commission. But in May, 2018 it became clear that a system leads to 98% of false operations. In the subsequent the group of researchers stated, as at all 100% of the so-called coincidence revealed from May to December, 2018 were incorrect.

Failure in London. The system of face recognition in the subway recognizes nobody

In the report prepared by experts from Cardiff University possibilities of technology in the conditions of weak illumination and accumulation of people - are called into question that does not promise anything good for tests of a system for some of the busiest streets of London some days before Christmas.

It is not cheap technology, but even if it would not be like that, at such digits it is difficult to expect return from investments. For several months of testing a system gave warning only once — when it "seemed" to the computer that in crowd there passed a crime suspect. This only operation was false. A system reacted to passing by the black young man. According to police officers, the difference between the picture of this person and the photo of the criminal from base of police with which there was a comparison is visible with the naked eye — to the person clearly at once that it is different people.

But even if the number of false operations is small in comparison with the number of the scanned persons, the problem is not limited to it. System deployment of face recognition in London did not lead to arrest of any criminal though law enforcement agencies laid great hope for technology. It does not promise anything good for full-scale system deployment which was planned by police.[1]
