The algorithm utilizes steganography, the practice of hiding sensitive information inside innocuous content in a way that obscures the fact that something has been hidden.

An algorithm developed by researchers at the U.K.'s University of Oxford and Carnegie Mellon University hides sensitive information in a way that makes it impossible to detect anything has been concealed.

Based on steganography, the algorithm uses minimum entropy coupling, in which two distributions of data are combined to maximize their mutual information while preserving the individual distributions.

Oxford's Christian Schroeder de Witt said, "Our method can be applied to any software that automatically generates content, for instance probabilistic video filters, or meme generators. This could be very valuable, for instance, for journalists and aid workers in countries where the act of encryption is illegal."
