What exactly do you think publishing hashes of Jan 6 pics would achieve?
The photographers posted them publicly on Facebook and Twitter. That’s how we have them in the first place.
The problem wasn’t knowing who took the photos, it was knowing who was in the photos. And that needs facial detection, which this system can’t do.
- jcims 5y agoIt would achieve exactly what the system is designed to do, mine personal devices for photos that authorities are aware of. Just because a lot of people were sloppy doesn’t mean every person was. However, my primary point is that there is no possibility of a technical control over the scope of the program. It’s a policy decision and is subject to explicit expansion or collusion/parallel construction.
- robertoandred 5y agoAre you referring to non-sloppy people who didn't post their pictures? In that case, their pictures couldn't be found anyway.
- raxxorrax 5y agoYou can quickly build relational graphs if you know which devices contain media that shares hashes. Sure, theoretical danger and not how this is implemented as hashes are just compared locally. This is different from accessing peoples contact lists they upload anyway because you want to group people in information bubbles that not necessarily correspond with real life contacts. This is very valuable info, isn't Google trying something similar?
- robertoandred 5y agoHmm? Again, who took the photo isn't a secret. They happily posted them publicly.
