主　　题：Quran text watermarking Arabic text capacity imperceptibility Kashida vowels reversing technique 

摘      要：The most sensitive Arabic text available online is the digital Holy *** sacred Islamic religious book is recited by all Muslims worldwide including non-Arabs as part of their worship ***,it should be protected from any kind of tampering to keep its invaluable meaning *** characteristics of Arabic letters like the vowels(),Kashida(extended letters),and other symbols in the Holy Quran must be secured from *** cover text of the Quran and its watermarked text are different due to the low values of the Peak Signal to Noise Ratio(PSNR)and Embedding Ratio(ER).A watermarking technique with enhanced attributes must,therefore,be designed for the Quran’s text using Arabic vowels with *** gap addressed by this paper is to improve the security of Arabic text in the Holy Quran by using vowels with *** purpose of this paper is to enhance the Quran text watermarking scheme based on a reversing *** methodology consists of four phases:The first phase is a pre-processing followed by the second phase-the embedding process phase—which will hide the data after the *** is,if the secret bit is“1,then the kashida is inserted;however,the kashida is not inserted if the bit is“0.The third phase is the extraction process and the last phase is to evaluate the performance of the proposed scheme by using PSNR(for the imperceptibility)and ER(for the capacity).The experimental results show that the proposed method of imperceptibility insertion is also optimized with the help of a reversing *** proposed strategy obtains a 90.5%***,the proposed algorithm attained 66.1%which is referred to as imperceptibility.
