Google’s Role In Woodland Child Pornography Arrest Raises Privacy Concerns

Slightly offtopic:

"Microsoft also developed Photo DNA to match pictures using just a pixel."

What. So if I give Microsoft a pixel with value #F00 it can determine if that's from a specific photo?

Great reporting with great insights and sources.

Ya that's ridiculous but it would be hypothetically possible if you had a sufficiently high number of colors. Then the chance of two images having a pixel with the same R, G, and B values all exactly the same would be exponentially small.

You could possibly do this by averaging all the pixels together for example.
