A steganography method based on decomposition of the Catalan numbers
Abstract In this chapter, we present a new method of steganography using decomposition of Catalan numbers. The proposed steganographic method consists of two segments: the first segment refers to the process of embedding data and generation of a complex stego key, whereas the second segment refers to the process of extracting a hidden message based on the generated stego key. Both segments consist of several phases. The proposed method provides that the data carrier retains its original shape. At the end of the chapter, security testing and steganalysis of the proposed method are conducted. Implementation in Java programming language successfully proves the work of the proposed method.
