There is a word for "You can't prove I said that", and even though English is my only language, I can't remember the word. It feels like "repudibility". I think I'm on the right track: https://en.wiktionary.org/wiki/repudiate https://en.wiktionary.org/wiki/repudiate
I think it is related to forward secrecy.
Maybe the E2EE apps should have a button for that, call it something snazzy like "The 5th Amendment button" and right next to that is a button for trivially forging texts and screenshots with the app's own UI, so that everyone knows that anything can be fake.
- Tomte 5y agoRepudiation
- hiq 5y agoThe Signal protocol already guarantees repudiation: https://en.wikipedia.org/wiki/Signal_Protocol#Properties https://en.wikipedia.org/wiki/Signal_Protocol#Properties But this is just cryptographic repudiation, meaning that a receiver cannot prove that they didn't tamper with their Signal data to fake having received a message from a certain sender. OP is talking about something else: preventing any data the receiver might have received to be transferred to a 3rd-party, but that's impossible.
