Key Dependent Covert Communication System Using Fibonacci P-Codes

In this paper, we present a key dependent covert communication system by incorporating Fibonacci P-codes and morphological statistical analysis. The key advantages of this process are: 1) The number of bit planes depend on the parameter P (ges 0 ) that could be used as key. 2) It is applicable to almost all digital imagery formats. 3) More number of digital information bits is focused over the least significant bit-layers. Thus, it has lower impact on the cover. The morphological variations of cover are employed for hiding secured information into the Fibonacci P-code bit planes. Simulation results were accomplished, using 30 color and 20 grayscale bitmap images varying in size, and classes of image features. In comparison with other existing adaptive and non-adaptive embedding methods will be presented. The proposed method also shows to have a greater resistance to detection.
