LLMs and Text-in-Text Steganography
Summary
This blog discussion explores steganography (hiding secret messages within other content) involving LLMs through techniques like white text on white backgrounds and deliberately misspelling words to confuse AI models. Commenters note that LLMs handle these obfuscation attempts easily, and discuss broader steganography methods including TEMPEST (electromagnetic emissions security), with mention that modern software-defined radios (SDRs, affordable radio receivers programmable via software) have made older defensive techniques less effective.
