British police to trial facial recognition system that detects your mood:

A British police force is set to trial a facial recognition system that infers people's moods by analyzing CCTV footage.

Lincolnshire Police will be able to use the system to search the film for certain moods and facial expressions, the London Times reports. It will also allow cops to find people wearing hats and glasses, or carrying bags and umbrellas.

The force has got funding from the Home Office to test the tool in the market town of Gainsborough, but ethical concerns have delayed the pilot's launch.

A police spokesperson told the Times that all the footage will be deleted after 31 days. The force will also carry out a human rights and privacy assessment before the trial gets the green light.

[...] "At the same time as these technologies are being rolled out, large numbers of studies are showing that there is... no substantial evidence that people have this consistent relationship between the emotion that you are feeling and the way that your face looks," AI Now's co-founder Prof Kate Crawford told the BBC late last year.

Could it be it was thrown off because everyone had a stiff upper lip?
