Query: Why Johnny Can't Use Stego: a Human-oriented Perspective on the
  Application of Steganography   Steganography is the discipline that deals with concealing the existence of
secret communications. Existing research already provided several fundamentals
for defining steganography and presented a multitude of hiding methods and
countermeasures for this research discipline.
  We identified that no work exists that discusses the process of applying
steganography from an individual's perspective. This paper presents a phase
model that explains pre-conditions of applying steganography as well as the
decision-making process and the final termination of a steganographic
communication. The model can be used to explain whether an individual can use
steganography and to explain whether and why an individual desires to use
steganography. Moreover, the model can be used in research publications to
indicate the addressed model's phase of scientific contributions. Furthermore,
our model can be used to teach the process of steganography-application to
students.
