“…Two weaknesses of ZKA are: (1) the retyping problem, and (2) the clear format problem. These deficiencies reduce the algorithm robustness [9]. Table 2 illustrates the changes in the carrier text and secret data when applying the ZKA algorithm.…”

This paper investigates eight novel Steganography algorithms employing text file as a carrier file. The proposed model hides secret data in the text file by manipulating the font format or inserting special symbols in the text file. Furthermore, the suggested algorithms can be applied to both Unicode and ASCII code languages, regardless of the text file format. In addition, a merging capability among the techniques is introduced, which allows alternatives for users based on the system requirements. The proposed algorithms achieve a high degree of optimized Steganography attributes such as hidden ratio, robustness, and transparency.

Abstract:In this research, we propose a new approach to increase the capacity and enhance the reliability of hiding voice data in Arabic text. Using Kashida to hide bits in Arabic text is one of the most promising approaches in steganography. Unfortunately, ignoring the original Kashida in the cover text may affect the results significantly and produce inaccurate results in the extraction process. In this study, we propose tremendous improvements to the Kashida method by considering original Kashida(-) in the cover text, error-detection using Cyclic Redundancy Check (CRC) and hiding bit using the "La" word. Moreover, hiding voice files within Arabic text is considered. The proposed approach is compared with the most related approaches in terms of capacity, security and reliability. Not only are the findings of the paper promising, they also overcome the limitations of other approaches.

“…In contrast with [8], we do not need to add another character beside the kashida to represent two bits. Each single existing kashida using the proposed method hides two bits by its own without merging it with a zero-width character which is used in this study just to distinguish between the original kashida and the kashida used to store secret bits.…”

“…Odeh and Elleithy [8], proposed a letter connectivity and extension to hide one bit approach. Moreover, they used zero-width letter, which is a letter used to connect two letters with a small effect on the shape of the two connected letters and no effect on the meaning of the word, to hide two bits in each connective character.…”
