Basically I am looking for a messaging platform like signal or? but with anonymous signup, perfect forward secrecy, capable of video chat, sending photos the usual uses in today’s life. But with a panic button. So that any party member could use said button to wipe all other members devices of any data instantly inside the messaging app. So if one member gets compromised, or lost their device, stolen device ect, any other member could wipe all chats, call log, and any other data strictly inside the messaging client instantly for everyone involved. Disolving the group like it never existed rendering the data unrecoverable. Amazons Wickr used to have most of these features but it is being discontinued December 2023 and who trusts amazon with their data. Does something like this exist? Sorry if I’m not explaining it well I’ll do my best to clarify and update this post. I am not trying to delete the whole device. Just the data inside the messaging app. If that does not exist. What about a separate app that could delete the entire messaging platform from the device when triggered. Assume all necessary requirements are met and this is for daily use. Between a group of trusted parties.
Updated wording to clarify the objective as replies where getting misunderstood.
I think the closest normal use case to your scenario is revocable sexting. Like a shared document folder in bitwarden or whatever that anybody could delete the keys for. So two romantic partners when they part could revoke access.
From a military perspective, your scenario really means you shouldn’t be storing that data at all. If it’s sensitive it shouldn’t be deployed in the field. If one element of an operation is compromised, they should not have any data to expose the rest of the operation. Compartmentalization.
I believe telegram secret chats will let members delete the chat for everyone. But that’s best effort and certainly not something you would want to put your life at stake over. It’s just data hygiene
Many replies here have misconstrued the total objective from my post… Of course someone could screenshot or disconnect their device. I am not looking for a foolproof feature or system. I understand compartmentalization. I do not need scenarios listed where this type of feature is useful. I understand my threat model and this is for a chat messenger not in person. You mention revokable access. But does that still leave the file on the lost,stolen device? Revoking access simply sounds like locking a file with encrypted keys. Thus it still exists on the stolen or lost device. Which means at some point or time future or otherwise a 3rd party could gain access. By all means correct me if I don’t understand.
