Internet black boxes" will be used to collect every email and web visit in the UK under the Government's plans for a giant "big brother" database, The Independent has learnt. Home Office officials have told senior figures from the internet and telecommunications industries that the "black box" technology could automatically retain and store raw data from the web before transferring it to a giant central database controlled by the Government. Plans to create a database holding information about every phone call, email and internet visit made in the UK have provoked a huge public outcry. Richard Thomas, the Information Commissioner, described it as "step too far" and the Government's own terrorism watchdog said that as a "raw idea" it was "awful". News that the Government is already preparing the ground by trying to allay the concerns of the internet industry is bound to raise suspicions about ministers' true intentions. Further details of the database emerged on Monday at a meeting of internet service providers (ISPs) in London where representatives from BT, AOL Europe, O2 and BSkyB were given a PowerPoint presentation of the issues and the technology surrounding the Government's Interception Modernisation Programme (IMP), the name given by the Home Office to the database proposal. "It was clear the 'back box' is the technology the Government will use to hold all the data. But what isn't clear is what the Home Secretary, GCHQ and the security services intend to do with all this information in the future," said a source close to the meeting.
