Same error as in the article, so for clarity/pedantry value: this is steganography (with a ga). Stenography is a fancy word for shorthand.

  and its still encryption, and they can prove that there is information there. A couple projects (one from uMich's CITI lab) showed that you can tell with high certainty when an image has steganographic data added too it.

    Nope. They can show _with a high certainty_ that the image is not quite usual; that's still a pretty long shot from _proving_ the irregularity is actually steganography (but that's where we leave the un/certainties of crypto and enter the realm of law).

      That is a fair point, they can show it was altered and "likely" to have concealed data but not that it does. Which would leave a reasonable doubt one would hope. I joked with Peter Honeyman once that perhaps I should just add 'bite me nsa' as a secret steganagraphic message in all my images so that they would have something to read. He suggested that the people who make a habit of taunting the bears in the circus are the ones who show up in the stories about bear attacks :-)
