I've been telling women to keep copies of all the dick pics they get sent. Since you can tell by the characteristic noise of a cameras sensor which other pictures were taken with the same camera. All missing is a search engine capable of doing this. I feel with AI, we are 2-3 years away from people uploading a dick pic to AI and getting the social media profile of that person...
Can you share some sources? I would be extremely surprised if such fine grained noise survives imagine compression to the extent that you could identify the source of an imagine despite changing lighting conditions, locations, exposure times, etc
A kagi search found this paper that achieved decent results on youtube compression, 5 years ago https://arxiv.org/abs/2012.06277
There are tons of results (and papers) if you google/kagi: "image noise fingerprint ccd sensor". I smell lazyness here.
This is just a data problem. The more dick pics we can feed into it then the better the results will be.
C'mon boys. Start uploading those dick pics for research purposes.
