Interception Modernisation Programme

The Interception Modernisation Programme (IMP) is a UK government initiative to extend the government's capabilities for lawful interception and storage of communications data. It has been widely reported that the IMP's eventual goal is to store details of all UK communications data in a central database.

The proposal is similar to the NSA Call Database established by GCHQ's American counterpart NSA and the Titan traffic database established by the Swedish National Defence Radio Establishment.

In 2008 plans were being made to collect data on all phone calls, emails, chatroom discussions and web-browsing habits as part of the IMP, thought likely to require the insertion of 'thousands' of black box probes into the country’s computer and telephone networks. The proposals were expected to be included in the Communications Data Bill 2008. The "giant database" would include telephone numbers dialed, the websites visited and addresses to which e-mails are sent "but not the content of e-mails or telephone conversations."Chris Huhne, the Liberal Democrat Home affairs spokesman said: "The government's Orwellian plans for a vast database of our private communications are deeply worrying."

The Home Office denied reports that a prototype of the IMP had already been built.

Reports in April 2009 suggest that the government has changed its public stance to one of using legal measures to compel communications providers to store the data themselves, and making it available for government to access, with then Home Secretary Jacqui Smith stating that "there are absolutely no plans for a single central store."
