For many years, Information Hiding has captured the imagination of researchers. Digital watermarking and steganography protect information, conceal secrets or are used as core primitives in digital rights management schemes. Steganalysis and forensics pose important challenges to digital investigators and privacy techniques try to hide relational information such as the actors' identities in anonymous communication systems. These and other topics share the notion that security is defined by the difficulty to make (or avoid) inference on certain properties of host data, which therefore has to be well understood and modeled. The special issue contains selected revised papers of the ACM Workshop IHMMSEC 2013, presented in June 2013 in Montpellier.
