Steganography is the art of covering or hiding writing, the purpose of steganography is covert communication to hide a message from a third party. The aim of this paper is to introduce an efficient and strong approach for hiding secret message within diacritical Arabic Text by using B+_tree as a tool for compress the secret message and DNA nucleotides as method for coding and Arabic diacritics as a cover text for steganography. The proposed approach is implemented on many diacritical Arabic text and the results are tested according to the authorized measures that are used in this field. And comparison is performed between the results that are obtained in this work with results that are obtained from other works in this field. The proposed approach has achieved a high capacity ratio for steganography form (79% to 106%)and also provides good security (transparency) for steganography based on some of similarity measures from (0.791 to0.9024).
