High capacity steganography tool for Arabic text using 'Kashida'
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 des...
متن کاملImproving security and capacity for Arabic text steganography using 'Kashida' extensions
Steganography is a method of hiding data within a cover media so that other individuals fail to realize their existence. In this paper, a new approach for steganography in Arabic texts is proposed. The main idea is that each Arabic word may have some characters which can be extended by 'Kashida'. The ranks 'locations' of such characters and the inserted Kashida, construct a coding method to rep...
متن کاملText Steganography using Extensions Kashida based on the Moon and Sun Letters Concept
Existing steganography methods are still lacking in terms of capacity. Hence, a new steganography method for Arabic text is proposed. The method hides secret information bits within Arabic letters using two features, which are the moon and sun letters and the redundant Arabic extension character “-” known as Kashida. The Arabic alphabet contains 28 letters, which are classified into 14 sun lett...
متن کاملHuffman code efficiencies for extensions of sources
It is well known that the efficiency of noiseless coding may be improved by coding extensions of the source; for large extensions the efficiency is arbitrarily close to unity. This paper shows that the efficiency is not always improved just by coding the next extension. In some cases the code of a larger extension is markedly less efficient than its predecessor, although always within the theor...
متن کاملAn Efficient Approach to Hide Compressed Voice Data in Arabic Text using Kashida and "La"
Corresponding Author: Jehad Q. Odeh Alnihoud Department of Compute Science, Al al-Bayt University, Mafraq, Jordan Email: [email protected] Abstract: In this research, we propose a new approach to increase the capacity and enhance the reliability of hiding voice data in Arabic text. Using Kashida to hide bits in Arabic text is one of the most promising approaches in steganography. Unfortunately,...
