SEARCH ENGINE GIANT Google has revealed that its boffins have been working closely with the National Centre for Missing and Exploited Children (NCMEC), adapting software to help hunt down paedophiles through image patterns on the Net.
Google reckons that the new adapted software, which is purportedly able to sort through files and pick out the ones depicting sexual abuse of children, will make it increasingly difficult for paedophiles who use the Internet to transmit child porn, and could even help law enforcement agencies track them down and rescue the abused kids.
According to the BBC, since 2002, the NCMEC has had to sift its way through more than 13 million videos and photos of children being sexually assaulted and last year alone, had to view five million sexual abuse pictures. But with Google’s software, which was originally developed so that YouTube could better detect video piracy and copyright infringement, NCMEC will be able to get through heaps more files thanks to the pattern recognition technology, which can pick up patterns from things as seemingly trivial as a calendar on the wall or the design of a t-shirt.
Google research scientist, Shumeet Baluja, told the Beeb "You always hope that your work will eventually be used to do some good in the world, and this was an amazing chance to make that hope real". Technology analyst, Larry Magid, also added that the technology “will work even if the pattern has been modified ". µ

As I understand it, the police have to look through the images of confiscated material and so they need regular professional counciling and 10 minute distraction videos of happy places to keep their brains from rotting after watching this material.

So God help the software developers and their families...they'll need a lot of support.
Google spying = good
gov spying = bad

Even if for the same cause, a private agency is praised for their work, but those who can actually do something about it are labeled as crooked.
