But we agree that the bar for something non-naive is extremely high if you want to defeat the well-funded adversaries and whatever they come up with in the next few decades (future algorithms will be applied to today's images). I'm sure they have nice libraries of the artifacts most cameras and compression algorithms should leave in any image and if it isn't there, well, let's look for some steganography?
- jakobegger 11y agoI'm pretty sure you are overestimating the capabilities of government agencies. At least I hope so.
- williamscales 11y agoHa! In general I assume that the NSA is ahead in many areas that remain classified.
- woliveirajr 11y agoI liked the idea... yes, it's possible to have a catalog of expected artifacts in JPEG images, in general. And the other way it would also make a good place to hide: changing artifacts from one camera to another, for example.
