High capacity diacritics-based method for information hiding in Arabic text

Abstract

New promising technique for information hiding in vocalized Arabic text is proposed in this paper. This technique makes use of diacritics (vowel signs), which are optional to put, by showing or omitting them to hide bits. The technique is found to be very useful due to the considerable provided capacity, and because every possible diacritic in the cover text is used to hide bits. In this method, even excluded or omitted diacritics will be hiding bits. Tests and comparisons show that the proposed technique is superior in matter of capacity to any related published work.
