Has anyone talked about how helpful would be for whistleblowers to have a time capsule for themselves that encrypts the data until the time arrives, and if it arrives notifies the user about it again? This way it would be way harder to trace back to them one or two documents, because they maybe wouldn't even work there anymore. I know SecureDrop aims to achieve that, but the problem is not everyone uses it. I've been thinking something that you have control over of. What do you think?
