Steganography: A Class of Secure and Robust Algorithms
Jacques M. Bahi, Jean-François Couchot, Christophe Guyeux · The Computer Journal · 2011
This research work presents a new class of non-blind information hiding algorithms that are stego-secure and robust. They are based on some finite domains iterations having the Devaney's topological chaos property. Owing to a complete formalization of the approach, we prove security against watermark-only attacks of a large class of steganographic algorithms. Finally a complete study of robustness is given in frequency DWT and DCT domains.
