Ribosome Inverts PhotoDNA
Anish Athalye (via Hacker News):
Microsoft PhotoDNA creates a “unique digital signature” of an image which can be matched against a database containing signatures of previously identified illegal images like CSAM. The technology is used by companies including Google, Facebook, and Twitter. Microsoft says:
A PhotoDNA hash is not reversible, and therefore cannot be used to recreate an image.
Ribosome inverts PhotoDNA hashes using machine learning.
This demonstration uses provocative images to make a point: rough body shapes and faces can be recovered from the PhotoDNA hash.
