Definitely, but like cryptography, this is very much a cat-and-mouse game. In some data uniform noise is harder to detect than other data. You also have to exploit streams that are large or expensive to analyze. But I think that there are many stochastic processes with near-uniform properties waiting to be exploited (such as e.g. some word order choices in some languages with free word order).<p>The thing is that with steganography, plausible deniability is much easier than pure cryptography.
