High Capacity Steganography Tool for Arabic Text Using Kashida

Steganography is the ability to hide secret information in a cover-media suchas sound, pictures and text. A new approach is proposed to hide a secretinto Arabic text cover media using Kashida, an Arabic extension character.The proposed approach is an attempt to maximize the use of Kashida tohide more information in Arabic text cover-media. To approach this, some algorithms have been designed and implemented in a system, called MSCUKAT(Maximizing Steganography Capacity Using Kashida in Arabic Text). The improvements of this attempt include increasing the capacity of cover mediato hide more secret information, reducing the le size increase after hiding thesecret and enhancing the security of the encoded cover media. This proposed work has been tested outperforming previous work showing promising results.
