5. Conclusion
This introduction to steganography shows the variety of techniques used. It is clear that the origin of this variety is twofold: on the one hand, it is linked to the types of data, and on the other, to the representation formats adopted. As the latter frequently evolve, so do the techniques, and their number continues to grow. As a result, we have only presented a limited corpus of techniques, albeit fairly representative of the digital domain.
One definition of steganographic system security is based on the probability distribution of the original documents and the documents obtained after concealment: the system is secure if these distributions are indistinguishable. This security model makes it possible to construct theoretical systems with perfect security. Unfortunately, these systems have no practical use. On the other hand, a major problem with this model...
