Facial recognition can identify you even if your face is blurred
A group from the Max-Planck Institute found that blurred images were still individually identifiable with just a few non-obscured images to train from. With the proliferation of images on social networks, it is possible that almost anyone’s blurred face could still be identified.
The researchers said only 10 fully-visible examples of a person’s face were needed to identify a blurred image with 91.5 per cent accuracy. With an average of just 1.25 tagged images, the system could still correctly identify an individual 56.8 per cent of the time, which is 73 times higher than chance would allow.
