Utilizing pseudo-spaces to improve Arabic text steganography for multimedia data communications

Abstract

Steganography is used for multimedia data security. It is a process of hiding the data within multimedia communication between the parties embedding the secret data inside a carrier file to be protected during its transmission. The research focus is on hiding within Arabic text steganography as a current challenging research area. The work innovation is utilizing text pseudo-spaces characters for data hiding. We present two studies for this text Steganography utilizing pseudo-spaces alone as well as combined with Kashida (extension character) as the old Arabic text stego techniques. Experimental results have shown that the proposed algorithms achieved high capacity and security ratio as compared to state-of-the-art Steganography methods presented for Arabic language. The proposed pseudo-spaces stego technique is of great benefit that can be further used for languages similar to Arabic such as Urdu and Persian as well as opening direction of text-stego research for other languages of the world.
