Digital Steganalysis
Lakatos, Attila ; Šimek, Václav (oponent) ; Strnadel, Josef (vedoucí práce)
The aim of this thesis is to introduce the basic theory behind digital steganography and digital steganalysis, present some recent algorithms and developments of the fields. Furthermore, it gives an insight into the ancient and recent history of the above stated scientific disciplines. This thesis elucidates the different approaches towards implementation of stegonography using image files. It also attempts to identify the requirements of a good steganographic and steganalytic algorithm and compares their performance with respect to requirements. In conclusion, the author's reflection towards the results, effectiveness of message hiding and success rate in detection are discussed.
