I think that this kind of automated stenography demonstrates that legislation requiring ~~mandated backdoors~~, ahem, "responsible encryption", is completely nonsensical: we could encrypt our messages with something powerful and safe, then encode it with something like this. Boom. Plausible deniability that you were sending anything other than plaintext. Sure, the plaintext is long-winded and verbose, and maybe a little nonsensical, but would a computer be able to reliably distinguish between encrypted-then-stenographically-concealed text and "real" plaintext? Anyway, really cool work.

That's part of what this project/paper is about, they created a model that not only produces text that passes as human, but it's significantly less detectable than previous encoding methods.

>Nonsensical E.g. One sentence of the 'cover text' I got read: "Then, on September 8, 1816, Sherman surrounded Army headquarters and killed three emissaries and surrendered with large supplies and safety pins." Sherman wasn't born until 1820.

  But, if you use a different LM Context that is not so easily fact checked then you won't realize that it is nonsensical. I used this LM Context: "This message contains confidential information and is intended only for the individual named. If you are not the named addressee you should not disseminate, distribute or copy this E-mail. Please notify the sender immediately by E-mail if you have received this E-mail by mistake and delete this E-mail from your system." To encrypt this fake, but real looking PII data: "Jeffery,Gourlay,2/2/55,495-24-1236" And produced this output cover text: "Disclaimer: An individual may be reminded of this email at any time by telephone from a different address, e.g. e-mail. However, online resources and other media (e.g. e-mailed stories, articles, etc.) that include original content, are not covered under this policy. The information contained herein" Malware or a bad actor could transmit this past enterprise InfoSec controls all day without easy detection.

    Also poetry might make for a good lm context. Nonsenicalness can be explained as artistical expression.
