Betting it'll be something like Cinavia, but for images and where the embedded data is a key instead of just a simple 1,2,3,4 code. With high color depths, such as greater than 8 bit, there's probably enough "dataspace" to embed data somehow (e.g. imagine embedding a data stream in a band above 20KHz for audio, it can be part of a 22KHz WAV file, for example, but won't be heard at all). The encoding wouldn't survive the situation where a picture is taken of a picture at a lower color depth, but that's probably OK.
