NewScientistTech writes about how Face-hunting software will scour web for targets:
'A search engine that uses sophisticated facial recognition to allow users to identify and find people in online images will launch next month. But civil liberties groups say the biometric-style tool could compromise the privacy of anyone who has their picture online.
Search engine Polar Rose reconstructs the 3D shape of a person's face and then combines that with characteristics of their features to generate a unique "face print". This can then be used to search other photos for a match.'
Of course, such software flags important privacy concerns:
'Although this sounds like a great idea, I would not like to be searchable in this way, or so easily tracked without my consent... is similar to the kind of biometric database some governments wish to use'
