Steganography is a technique for hiding data in media in a way that makes its existence hard to detect. Text files are a preferable format for use in steganography due to the small storage size of such files. This paper presents an Arabic text steganographic algorithm based on Unicode. The algorithm imposes a minimal change on connected letters without any change in size and shape. The experiment resulted in a high capacity rate ratio of about 180 bit/KB and low modification rate less than 90 letters/KB.
