This is the year when automated face-recognition finally goes mainstream, and it's about time we considered its social and political implications. Researchers are developing sharply accurate scanners that monitor faces in 3D and software that analyses skin texture to turn tiny wrinkles, blemishes and spots into a numerical formula. The strongest face-recognition algorithms are now considered more accurate than most humans - and already the Home Office and the Association of Chief Police Officers have held discussions about the possibility of linking such systems with automatic car-numberplate recognition and public-transport databases. Join everything together via the internet, and voil - the nation's population, down to the individual Times reader, can be conveniently and automatically monitored in real time. So let's understand this: governments and police are planning to implement increasingly accurate surveillance technologies that are unnoticeable, cheap, pervasive, ubiquitous, and searchable in real time. And private businesses, from bars to workplaces, will also operate such systems, whose data trail may well be sold on or leaked to third parties - let's say, insurance companies that have an interest in knowing about your unhealthy lifestyle, or your ex-spouse who wants evidence that you can afford higher maintenance payments.
