Arvind Krishna, CEO of IBM, has decided to get out of the facial recognition business. His letter to the US Congress waffled about advancing racial equality. That's an utter non-sequiter, of course. What he meant was this **** is a potential litigation money-pit and we want no part of it. Or if he didn't, you may want to consider shorting IBM stock.
Facial recognition software is widely available. There's a Python library for it. It uses a package called dlib. Apple has facial recognition software. Facebook has its own algorithms, as does Google. A recent study by the NSIT included 189 algorithms from 99 developers. That survey concluded that facial recognition software works just fine for white folks, and pretty well for Chinese, Koreans and Japanese. It totally sucks when identifying African women, half of whom it thinks are men. The darker the skin, the less well it works.
In the 2011 UK Census, 87% of the UK population weas White, 3% Black, 4.2% from the India and Pakistan, 2% were mixed and the remainder Arabs or Far Eastern Asias. In Newham, however, only 29% of the population is White (no, that's not a typo). That's a lot of poor identification. In 33 districts of England the proportion of Whites is below 80%, and those are the populous ones.
The concern is that a local council or police force will buy a cheap algorithm, some second-rate cameras, and use a mid-range scanner to load up their rogue's gallery to the database. The result will be a mass of false identifications, accusations and arrests, disproportionately affecting people with black or brown skin. The council or police force will do what all public bodies do when they make a dumb decision, which is double-down. Next thing you know, half your council tax is going on out-of-court settlements to not-actually-minorities-in-that-postcode represented by solicitors who play golf with the councillors. Or whatever those people do.
The world is full of unaccountable bureaucrats with way too much power. Giving them facial recognition would be dumb. Not as dumb as locking down your country, but you know, half-way there. We should be concerned. So should anyone supplying this stuff: it should not be sold to just anybody. Especially to anybody who can fine us, lock us up, and put us on registers we should not be on. Which is pretty much any Government department or agency. Of course the Spies will have the really good stuff (at least I hope they do) but the Spies can't lock anyone up. At least in this country.
If IBM thinks it can't beat the ethinic-facial-recognition problem, it's a good bet that no-one else can. Unless the people at IBM aren't as smart as they used to be. Facial recognition is a nice toy for social media, and a useful tool for organisations with large photo libraries of public figures. However, the real money is in security and surveillance, and IBM have decided that there wasn't enough to justify the risks.
