Tech world may face fines if it doesn't scrub CSAM from encrypted chats

let me get this straight, if CSAM is a problem in encrypted chats today or in future, how many convictions have happened in the last 10 years when there wasnt much encrypted chats in the first place? CSAM is being thrown around as a scapegoat in order to not allow anti-establishment discourse or dissent. edit: wasnt that guy in USA or somewhere arrested and held in comtempt of court when he said he forgot the password of his drive? why arent you doing that on a case to case basis as opposed to mass surveilance?

That is basically disallowing chats for anyone aside the largest tech companies that actually can filter on a large scale. Although I believe it would only be applicable to them anyway. End-to-end encrypted messages cannot be scanned. They simply are not end-to-end encrypted otherwise. You can do it client side but that is easily mitigated by perpetrators. To be honest, there are much better methods to fight child abuse. And disallowing people using end-to-end encryption and forcing big tech to scan all messages is an extremely high cost. Not that they do that anyway in most cases because legislation is falling behind...

So, if I want a nice large feed of child porn, all I need to do is fork Signal, glue in some image search/comparison code, and notify the UK Home Office that I now require a feed of the material I should filter out. I can't quite believe that. But how would they expect filtering to work without giving the service providers the things to check?

  Hashsums, yes it sucks, but the hash algorithms more tunes to the task.

    A friend of mine worked on that. "Rotating the images 1° defeated our system completely," he said about his (then previous) employer's system, and he saw no way to really improve it. The Brits could hardly deploy something with such obvious known defects.
