Some day we have to use packets which are pre-filled by random data to hide our keystrokes in. Not quite steganography, but close. Could also be used to make traffic-analysis harder/impossible even?

- luckystarr 3y agoI just found the term "traffic padding", which seems to accurately describe this.

- pizza 3y agoYou could do steganography with this. There's work on getting a language model to re-word an innocuous cover-text by using a minimum-entropy, key-derived distortion of the probability distribution that is used to sample words. Then, if you use the same model on the receiver side, and have the key, you can decode the covertext back into the ciphertext. This also works with images, too. https://openreview.net/forum?id=HQ67mj5rJdR https://openreview.net/forum?id=HQ67mj5rJdR
