This project aims at unifying the terminology and taxonomy for hiding methods in steganography. This project is driven by a consortium of several scientists from currently ten institutions spread over five countries.

Steganography embraces several hiding techniques which spawn across multiple domains, such as digital media steganography, text steganography, cyber-physical systems steganography, network steganography (network covert channels), local covert channels, and out-of-band covert channels. However, the related terminology is not unified among the different domains. To cope with this, an initial attempt has been done in 2015, with the introduction of the so-called hiding patterns (Wendzel et al., 2015), which allow to describe hiding techniques in a more abstract manner. Despite significant enhancements, the main limitation of the original taxonomy is that it only considers the case of network steganography. For this reason, the hiding patterns project aims to unify and find agreements for the terminology and taxonomy in all domains of steganography, including related disciplines.
