| Challenge: | steganography encodes hidden messages into model-generated tokens . tradeoff between how much hidden information can be introduced and how much the model can be perturbed is important . |
| Approach: | They propose to use large language model-based steganography to encode hidden messages into model-generated tokens. |
| Outcome: | The proposed techniques are nearly optimal under a practical but difficult set of constraints . the proposed techniques ensure that only someone with the appropriate decoding key can access the hidden information . |
