Steganography in Arabic Text Using Full Diacritics Text

摘要

The need for secure communications has significantly increased with the explosive growth of the internet and mobile communications. The usage of text documents has doubled several times over the past years especially with mobile devices. In this paper we propose a new Steganogaphy algorithm for Arabic text. The algorithm employs some Arabic language characteristics, which represent as small vowel letters. Arabic Diacritics is an optional property for any text and usually is not popularly used. Many algorithms tried to employ this property to hide data in Arabic text. In our method, we use this property to hide data and reduce the probability of suspicions hiding. Our approach uses a performance metric involves the file size before and after adding Diacritics and ability to hide data with being suspicious.
