If you have a Facebook page (who doesn't?) and you worry about your privacy, you may want to rethink posting photos of your face on there. We told you in the past that Facebook has billions of high-quality photos of many of its 1.5 billion users.
In fact, its database of faces rivals or surpasses that of the FBI, which last year had 50 billion images. It's using those photos for its Next Generation Identification, which is improving on its use of fingerprints to identify people.
At one time, the FBI had the world's largest person-centric biometric database. But Facebook likely has the FBI beat on that front, and that's got governments interested in your photos.
In fact, the Australian government may start collecting biometric data on its citizens and, importantly, non-citizens as part of the country's immigration policies. Now, Australia is proposing creating a database of faces that may include siphoning images from social media sites like Facebook, for its anti-terrorism efforts.
