Inclusion of Unicode Standard Seamless Characters to Expand Arabic Text Steganography for Secure Individual Uses

The need to protect confidential data stored on personal computers (PCs) or sent to other parties hasincreased significantly. Therefore, a secure, high-capacity strategy is needed to cover the data containedwithin media and make it difficult to detect. Due to the limited number of research studies that haveachieved these ends through text steganography, we present an innovative approach for hiding secret bits inArabic text with Unicode Standard seamless. Our method uses the contextual forms of Arabic characters tohide certain secret bits. Extra characters such as Zero-Width Joiners (ZWJ), Kashida, MediumMathematical Spaces (MMSPs), and Zero-Width Non-Joiners (ZWNJ) are also used to further enhance themethod’s capacity without diminishing the data’s security. Our experimental results show that thistechnique outperforms similar methods with an average improvement in capacity of more than 50%. Thistechnique also has a higher security ratio than the other methods in this study, with the exception of Method5, and is robust against electronic text modifications such as copying, pasting, and text formatting.Moreover, our algorithm can be widely adopted in related languages, such as Urdu and Farsi, due to itsutilization of Unicode characters, which is the encoding standard used in most of the world’s writingsystems .
