David Cameron: Spies tracking internet paedophiles are like the Enigma code breakers of World War II The Prime Minister added: "There has been a lot in the news recently about the techniques, ability and brilliance of the people involved in the intelligence community and GCHQ and the NSA in America and that expertise is going to be brought to bear to go after these revolting people sharing these images on the dark net and making them available more widely. The point is that you use technology which is able to get into the dark internet, which is able to decrypt encrypted fields, which is able to find out what is going on and, like all these things, if you put in the resources and the effort if you use the best brains, as it were, the inheritors to the people who decrypted the enigma codes in the second world war. If you take those brains and you apply them to the problem of tackling child abuse online you'll get results. On Twitter Cameron declared today's announcements by Google and Microsoft a "major victory" for the government's online campaign. Jim Gamble, former Child Exploitation and Online Protection Centre (CEOP) chief executive, said that while Mr Cameron's influence has "accelerated" the process of getting the search engines to ban 100,000 search terms. However he said it was the peer-to-peer networks that need to be targeted if the Government wants to track down paedophiles. He said: "Very few paedophiles in my experience use Google." At the end of the day a pop up message is not going to inform, educated or scare a paedophile they know what they do is wrong, that's why they are secretive about it that's why they hide in the peer to peer of the dark web where they cant be found.
