The JPEG Committee is “exploring Blockchain” — to put DRM into JPEG

«The JPEG Committee is “exploring Blockchain” — to put DRM into JPEG»

Why DRM is a second-rate idea

It’s worth noting here that DRM literally, mathematically, doesn’t work — it’s the trusted client problem. Your whole threat model is to declare your own user the enemy. As Wikipedia puts it:

Trusted client software is considered fundamentally insecure: once the security is broken by one user, the break is trivially copyable and available to others. As computer security specialist Bruce Schneier states, “Against the average user, anything works; there’s no need for complex security software. Against the skilled attacker, on the other hand, nothing works.”

I'd have expected this from the IJG. That it comes from JPEG, instead of breaking the chicken-and-egg problem of getting XS or XT out to the world, is surprising.
