Has Facebook killed the undercover cop?

Face-recognition technology and the near-universal adoption of social networking tools by teenagers could have already made future covert police and intelligence operations difficult, if not impossible, according former Australian Federal Police commissioner Mick Keelty.

"You don't just immerse somebody into an organised crime group. It takes sometimes five, six, seven years to be able to get them into the right place where you need them to be feeding back the intelligence you need," Keelty told the Security 2011 Conference in Sydney yesterday.

Yet that undercover operative's cover could be blown by simply taking photograph and comparing it with images already posted online. Current face-recognition software can even match images taken decades apart.

Keelty is currently researching the policy implications of social networking for covert operations by  police and security agencies in his roles with Charles Sturt University and the Australian National University.

As part of his research, a survey was conducted on all of the recruits for the AFP and NSW Police, and for "some other agencies, national security agencies, as well as some other state agencies" from late 2010 through to February 2011.

"Interestingly, everybody aged 26 years or younger had uploaded their photo onto the internet," Keelty said. 85 percent were using at least one of the major social networking sites. Some 47 percent were using them daily, and another 24 percent weekly.

Of those surveyed, 85 percent had had their photos uploaded by another person, and 42 percent said it would be possible to identify their relationships with other people.

Apart from the massive trove of photographs on social networking sites like Facebook, which receives 100 million new images every day, governments and other organisations can create their own long-term image archives.

"We had anecdotal evidence given to us that outlaw motorcycle gangs were actually going to police graduation parade and taking photos, because some of you in the room would be aware that outlaw motorcycle gangs actually won a lot of tenders for contacts for major entertainment establishments around the capital cities of Australia during the last decade," Keelty said.

"How can you turn up at the Australian embassy in Jakarta and say that you're the trade commissioner for education when you've got a photograph of your graduation from [Royal Military College] Duntroon in 2006 and an unexplained absence from the world in the interim years?"

The same combination of technologies could also make things difficult for witness protection programs, and open up formerly-unidentifiable public servants to the threat of extortion and other crimes.

"Facebook, we have to say, has been difficult in trying to get them to come on board about the privacy issues associated with their network.

But there is a positive side.

"There's a gold mine of intelligence that comes out of all of this," Keelty said, pointing to the use of social networking tools by police in the Queensland floods and for identifying suspects in the UK riots.
