"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.
- Houshalter 13y agoYa 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.
