This is a confusing question. The two seem to have nothing to do with each other. Open source means the source code is available to read. Disappearing message

This is a confusing question. The two seem to have nothing to do with each other.
Open source means the source code is available to read.
Disappearing messages means you can delete things from your device and ask the other side to delete them as well.
- closeparen 7y agoA user who is in control of their client software can just comment out the self destruct part.
- noman-land 7y agoExactly. Or they could just take a screenshot or a slew of other things. One of the reasons Signal use deniable encryption is because if a message that supposedly comes from you is sitting in someone else's chat, they have no way of proving that you sent it vs them putting it there.
- geofft 7y agoNot necessarily - Signal can show a warning icon to people they're having conversations with / only enable the feature if everyone in the group is on an official client. Nothing about it being open source prevents this, and conversely, making Signal closed source wouldn't prevent people exfiltrating content via jailbroken phones etc. (Or via screenshots, as others have mentioned.)

- deogeo 7y agoA modified client could simply claim to be official.
- geofft 7y agoDo the mobile platforms give you a way to authenticate an app as the official app of a certain ID? I thought they did but now that I think harder I'm not actually sure how to implement it. If they do, it's "just" that plus jailbreak detection.
