It will be able to identify individuals on social networking sites and online galleries by comparing their image against a known picture of them, according to Face.com. Detailed profiles of individuals will be built up purely from online photographs, which also will be helpful for employers.

The Photo Finder software, which is already released, will allow people to search for anyone on the internet. The technology is already being used by 5,000 developers.

The use of facial detection technology has only been used by the UK Border Agency.

Simon Davies, director of Privacy International, said: “I think this will make many people very uneasy.
The regulators have been hugely behind the curve of protecting people’s privacy on the internet. We need to push for much tighter international rules.”
