Intelligence operatives
This technology hides encrypted messages inside ordinary-looking text generated by an AI language model. A sender's original message is encrypted and then used to steer a language model to produce natural-sounding text in any target language, with no apparent connection to the original content. That cover text is split across multiple apps or communication channels to avoid detection. The receiver uses the same language model to reverse the process and recover the original message.
What you could build
A secure messaging platform or SDK for defense contractors, government agencies, and journalists that wraps existing chat apps and automatically converts sensitive messages into innocuous AI-generated conversation, making covert channels invisible to network monitors and censors.
