To securely conceal their information, digital steganographers aim to embed messages in strings of words or images that are statistically identical to normal communication.

Computer scientists from the U.K.'s University of Oxford, Carnegie Mellon University, and Switzerland's armasuisse Science + Technology claim to have created the first algorithm for seamlessly concealing messages in realistic text, images, or audio.

The researchers used the generative artificial intelligence (AI) to design innocuous-seeming chat messages that outside observers could not distinguish from any other communication produced by the same algorithm.

The algorithm can couple a secret message with a series of memes included in the chat, selecting context-appropriate content on the spot.

The researchers envision the method gaining use with the emergence of increasingly commonplace generative AI.
