«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.”
