I am aware that encryption is still required; steganography will
commonly be used in concert with encryption. As to the feasibility of
detecting steganography, there is a fair amount of work on the
subject, e.g.:
http://www.jjtc.com/Steganalysis/
http://www.securityfocus.com/infocus/1684
http://en.wikipedia.org/wiki/Steganography

And see the references in the Wikipedia article.
