Abstract
Steganography is the ability to hide secret information in a cover-media such as sound, pictures and text. A new approach is proposed to hide a secret into Arabic text cover media using "Kashida", an Arabic extension character. The proposed approach is an attempt to maximize the use of "Kashida" to hide 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 media to hide more secret information, reducing the file size increase after hiding the secret and enhancing the security of the encoded cover media. This proposed work has been tested outperforming previous work showing promising results. (C) 2010 ISC. All rights reserved.
