The Information Commissioner, Richard Thomas said, UK would be facing significant risks, if giant databases of personal information are created.
Thomas is of the view that it might raise the risk of data going missing and bad decisions made based on people's files.
As of now, 30 "serious" breaches of data protection law by the government and other bodies are being investigated by Mr Thomas. Thomas is planning to advise that the least amount of data possible should be held, at his speech at the Royal Society of Arts in London.
