An algorithm has been developed that conceals sensitive information so effectively that it is impossible to detect that anything has been hidden. This is the claim of a team led by Oxford University ...

Joint UK-US team finds way to send perfectly secure secret digital communications without cryptography or quantum computers Advances in information theory are behind a new steganography algorithm ...

A team of researchers has developed a new method of hiding information inside innocuous-looking documents. The technique itself – steganography – has been used in various forms for centuries; it ...

Researchers have achieved a breakthrough to enable 'perfectly secure' hidden communications for the first time. The method uses new advances in information theory methods to conceal one piece of ...
