Arabic text Steganography has gained increased attention in recent years, utilizing characteristics of Arabic language in hiding information. Arabic poetry system has an embedded binary representation that can be used for hiding secret data. In this work, we propose a steganography technique to utilize this binary redundancy available in the Arabic poetry system for steganography. The capacity of the proposed technique has been improved by inserting diacritics or kashida in some cases. Experimental results proved that the capacity of the proposed technique exceeds most of the previous techniques.
