Disbursal of Text Steganography in the Space of Double-Secure Algorithm

Abstract

Hackers reveal sensitive information from encrypted conversations as the globe has become one community. As a result, steganography and cryptography are used together to safeguard sensitive data more effectively than previous approaches and newly developed algorithms. A double-secure algorithm for text steganography (DSTS) is the safest approach compared to the paragraph hiding method (PHM) and capital alphabet shape encoding (CASE) method. In this context, the paragraph hiding method uses ASCII coding, which is not a standard method, and the CASE method has a security issue that if someone understands its applicability, it can be easily attacked. DSTS algorithm overcomes its limitations by using UTF-16 coding and enhances the security of CASE with a one-time pad (OTP). The one-time pad is a theoretically unbreakable cryptographic method. Still, it is not feasible for long messages, however, it is usable for short messages such as a password or intelligence agency’s more secure messages. DSTS degrades the average hiding capacity in a PHM from 2.06% to 1% due to UTF-16 coding. Using the UTF-8 method, the authors have improved MDSTS and the CMPHM by 6.49% and 7.76% hiding capacity, which outperforms in existing procedures; in the CMPHM, there is one reason for the improvement in hiding capacity is using the LZW compression method. CMHPM algorithm optimization standard deviation is less than that of the HPM, DSTS, and MDSTS, ultimately increasing speed.

CSNTSteg: Color Spacing Normalization Text Steganography Model to Improve Capacity and Invisibility of Hidden Data

“…The CSNTSteg model and techniques proposed by [8,11] have improved the invisibility by 4.7%, 3.3%, and 2.4%. Although there is a slight improvement in [8,11] Despite the fact that CSNTSteg applies to any text color, it has limitations for character spacing when used in languages that join the letters together, such as Arabic, Persian, and Jawi [43,44,99,100]. In contrast, the CSNTSteg model has better results in robustness by 94.22 percent.…”

Performance Review of Feature-Based Method in Implementation Text Steganography Approach

“…Security is a crucial indicator of how much sensitive information is hidden from intruders. Capacity is the quantity of private information it can deliver to the recipient in the stego text [40,41]. It is called contradiction performance because if the technique achieves one or two specific performances, it will decrease the other performance.…”

Text Steganography Using the Second Quotient Remainder Theorem and Dark Colour Schemes

“…Due to the possibility of attacks and unforeseen changes during an active transmission across an unsafe network, it is challenging to establish trustworthy communication between two parties that share personal data (Khan, Algarni, Fayomi, & Almarashi, 2021). Failure to ensure that the information sent is protected can result in it being tampered with by irresponsible parties.…”
