An anonymous reader writes: The U.K. government has lost the personal information of up to four million citizens in one year alone. The astonishing figures, calculated by the BBC, added up as Whitehall departments slowly released their annual reports for the year to April. And the trend has not stopped — in the latest revelation, HM Revenue Customs, which infamously lost the details of 25 million child benefits claimants last November on two unencrypted discs, experienced 1,993 data breaches between 1 October last year and 24 June. Earlier this week, the Ministry of Justice admitted it had lost 45,000 people's details throughout the year, on laptops, external security devices and paper, and that 30,000 of them had not been notified. Before that, the Home Office announced it had lost the data of 3,000 seasonal agricultural workers on two unencrypted CDs. In May, the Department for Transport lost the data of three million learner drivers. Other data losses occurred at the Foreign Office, which lost 190 people's data in five incidents. In January, the Ministry of Defence said it had lost a laptop containing the details of 620,000 recruits and potential recruits, and some information on 450,000 referees for job applicants. The Liberal Democrats have called for 'data guardians' to be appointed to monitor the government's handling of information.
