Its steganography to hide a bitcoin txn from a human inside a hidden channel. But its so simple to hide from a packet inspection engine I wouldn't even call it steganography... for example the "image" downloaded could look like random bits to a person (obviously not a meaningful image) but the packet inspection engine would not be able to determine that.
We need to act soon, because if the 5 Eyes has their way (and they are almost there) then the world will accept that HTTPS means encryption but in fact it does not. Then the NWO will say that any data that is encrypted (i.e. random) but not done with HTTPS is prohibited on the internet. The public is almost to the point of gleefully agreeing.
