The cypherpunks were right. Rights to encryption are only a part of what we need.

The other part is steganography, or hiding real messages within a innocuous anodyne message stream. And encryption can be used in conjunction as part of hiding said messages.

It can be within pictures with the lowest bit values. It can be constructed punctuation and spaces. Lots of things.

But hidden and plausibly deniable messaging is the ONLY way to defeat a government(s) that want to invade every communication aspect for humans.

What I don't understand is, what kind of legitimate criminal would not use such techniques? Are bank robbers planning things out on iMessage? If so, presumably they won't be criminals for very long. Therefore these types of initiatives only impact the innocent and inept but still active criminals.

The trouble with pictures is that when you share them online the platform will likely compress them before serving them to others, spoiling your steganography. I think text-in-text is the way to go. Decrypt that recipe for brownies into the actual message. For example: https://arxiv.org/abs/2510.20075

That's an excellent take.

Unfortunately, verified devices will close that loophole.
