SLR photo chip -> Cryptographically Signed Image -> Blockchain or Other Trust System Documents Production of Image and with key system thar matches image to record, all alterations to image are documented on said blockchain/other trust system.
Verifiable system for chain of custody.
- vasco 3y agoTake the SLR camera, hook it up to a computer with a custom driver, every time you generate a new picture through AI, invoke the camera keying process programmatically. Most likely don't even need the camera when an exploit is found for the hardware.
- SubiculumCode 3y agoTPM is that broken?
- zmgsabst 3y agoCut the sensor out and wire it to USB. Or get a premade Chinese device that will do it for you, just like they happily broke HDMI encryption to make splitters work.
- 542458 3y agoI don’t think you even need that level of sophistication. You can probably get “good enough” results just pointing the camera at a high-res screen displaying the manipulated image and putting it slightly out of focus.
- ovalite 3y agoPossibly a new use case for light field cameras which is able to capture depth information from their sensors.

- dizlexic 3y agoI love the idea of universal traceable media and data. I'm sure that will in no way be a bad thing.

Verifiable system for chain of custody. You can have a fully verified factual photo that is still a lie. Early pandemic had some great examples of this. Journalist wanted to show how crowded cities like NYC were despite distancing rules. So they took telephoto shots of people standing in line facing the camera. This squeezes the perspective and makes them look bunched up. Same photo taken with orthogonally to the line shows that people stand 6ft apart. Here’s an article that explains this in more depth: https://mainichi.jp/english/articles/20210126/p2a/00m/0op/009000c https://mainichi.jp/english/articles/20210126/p2a/00m/0op/00... You don’t even have to cheat that obviously. A photo can lie just by showing, say, a bunch of soldiers holding guns next to scared children. Oh no look at those scary foreign soldiers terorizing the populace! What you don’t see is the humanitarian aid truck behind them and the workers distributing food to those children. Turns out the soldiers were there to protect the aid process, not to terrorize children. This is not a technology problem.
- iamacyborg 3y ago> Early pandemic had some great examples of this. The American civil war has some great examples too.
- sneak 3y agoPrecisely zero photos you see in media are unedited/uncropped "straight out of the camera" (as we say). Professionals don't even shoot in formats that web browsers can display. I'm certainly not posting my 160MB raw files to the web. What you propose is thoroughly a non-solution (to a non-problem).
- Manuel_D 3y agoThe idea is that the raw photo files are cryptographically signed. Of course they're going to be edited, retouched, etc. But if a media outlet is challenged on the veracity of the photo - as in, claiming it's totally fabricated, not just touched up - then the signed raw file adds credibility.
