A novel approach to the security of data hidden in multimedia objects
Yevhen Zolotavkin, Vitalii Lukichov, Anatoliy Vasyura · 2008
The criterion for detecting hidden data in the fractal code of images has been suggested in the article. The approach consisting in estimating steganographic threats of every record in the fractal code has been used. This estimation has been based on the special features of fractal compression. The number of the positively estimated blocks has been used for drawing a general conclusion about the possible presence of embedded data. The efficiency of the developed detector has been determined experimentally and compared to the current ones.
