‘As a baby boomer, I didn’t grow up with Facebook and other social networking sites. While I do use them – mainly to keep up with younger members of my family – I’m keenly aware of their potential to invade privacy.
Consider the fact that Facebook has amassed what may be the world’s largest photo database, consisting of more than 500 billion pictures. Then combine that figure with mobile technology like MORIS, the “Mobile Offender Recognition and Information System.” MORIS is a facial recognition program used by police. An officer simply snaps a photo of your face and runs the image through software that hunts for a match in a criminal records database.
MORIS can scan your face from up to five feet away, potentially without you being aware of it. Since you have no “expectation of privacy” in a public location, the law doesn’t consider this a “search,” and you need not consent to this intrusion.’
