Richard Bilton meets people who watch us and those who have fallen foul of modern surveillance

A new three part series looks at why the UK has become one of the most watched places in the world - with millions of CCTV cameras, a growing network of number plate recognition cameras, one of the largest DNA databases in the world and government plans for the basic details of all our phone calls e-mails, and every internet site we visit to be logged and kept.

We all benefit from better crime detection and from easier and cheaper services. The government argues that: "If you've got nothing to hide, then you've got nothing to fear."

Richard Bilton explores the hidden world of surveillance.

He goes inside the CCTV nerve centre, sees how all of our journeys can be monitored, and meets undercover agents, those who are watched and those who have fallen foul of modern surveillance.

Who's Watching You? explores why increasingly we are all being watched and why some think we have already become a surveillance society.
