Abstract

 Since steganography and cryptography are information security concerns, they gain wide importance in the
researcher's studies. DNA based steganography is based on exploiting DNA nucleotides as confidential information
carriers which enhance the data hiding process massively. A special kind of hiding mechanism is adopted in this work by
using the DNA sequences that depend on iterating a 3D logistic chaotic map to generate three pseudo-random
sequences. The proposed approach encodes the plain message bits together with two of the random keys into DNA
sequences. It ensures extra DNA encryption, by carrying out some DNA sequence operations. Besides, it creates a fake
sequence by embedding the generated sequence into another public reference sequence. The fake sequence is then hidden back into the cover image to achieve a double layer of data hiding. Experiments verifies that our approach satisfies the robustness of data hiding under reasonable average embedding capacity of 0.83 ,blindness, zero-payload, low modification rate of 5.16% (on average), zero-expansion rate, and high probability cracking.it is also considered as a double layer of security , dual hiding , not pure data hiding system, with adequate visual imperceptibility
