If you find Facebook's facial recognition and photo tagging kind of creepy, the police may find it downright dangerous.
Mike Keelty, a former Australian Federal Police commissioner, said that Facebook may make undercover policing "impossible" in the future:
“The thinking we had with this result means that the 16-year-olds of today who might become officers in the future have already been exposed.
"It’s too late [for them to take it down] because once it’s uploaded, it’s there forever.”
Of the people surveyed, 85 per cent had their photos uploaded on to the internet by another person.
Keelty said that until recently this has been a real problem because Facebook refused to remove photographs, but because of competition from Google+ it had started to remove photos at people’s request.
Alarmingly, 42 percent of respondents said it would be possible to identify their relationship with other people, including family and friends.
"If you have someone in the service who is trying to remain anonymous for whatever reason, it is still possible through other relationships to find them," Keelty said.
