From watching our neighbours, to being watched at work, online and on the move, surveillance is everywhere.
Information about every bit of our lives is valuable to somebody.
WHO'S WATCHING YOU?
Monday, 1 June, 2009
BBC Two, 2100 BST
Richard Bilton meets those who have made our private lives their business including former soldiers watching suspected workplace thieves, corporate spooks trawling companies' rubbish for lucrative secrets, suppliers in the booming trade in tracking devices, secret cameras and hidden microphones.
And Who's Watching You? delves in to the criminal underworld of hackers and blaggers who steal and sell our information.
Surveillance can benefit us all, helping make businesses more profitable and the services we use more convenient. But, as Richard discovers, surveillance has a darker side too.
