AH4S: an algorithm of text in text steganography using the structure of omega network

Abstract

This article introduces a new technique to hide text-in-text messages. The proposed mechanism uses the structure of omega network to hide and extract secret messages. The generation of secret message is made as follows, take every letter from the original message, use the omega network to generate two related letters from the selected letter, and finally search the dictionary for a suitable English cover word to hide the generated two letters. In order to increase the chance of find a suitable words, the generated two letters need not to be adjacent in the cover word. As a result, the white-space steganography is used in order to hide the position of the two letters in the selected cover word. The experiments show that the proposed mechanism gives a better execution time and better cover words than the current similar mechanisms especially when we are trying to hide long text messages.

Text Data Security and Privacy in the Internet of Things: Threats, Challenges, and Future Directions

“…e information hiding is categorized into steganography, cryptography, and watermarking as shown in Figure 2. A secret message is embedded in digital content without affecting the original text, which authenticates the ownership verification [25,26].…”

A New Way to Store Simple Text Files

“…Discussed method concerns (among other issues) steganography of the text. In the literature, one can find many works on this subject, e.g., [20][21][22][23][24][25][26][27]. Most of them use large amounts of non-confidential information (media) to be able to hide in a piece of the confidential message.…”

“…Thanks to horizontal or vertical symmetry of the alphabet characters, the corresponding bits of the confidential message are hidden, creating appropriately modified text. In turn, Reference [21] developed a method of hiding text using the omega network. This method consists of generating a word from a dictionary that contains two letters coupled using an omega network with one letter of messages to hide.…”

Modern Text Hiding, Text Steganalysis, and Applications: A Comparative Analysis

“…Therefore, demand is growing for intelligence and multimedia security studies that involve not only encryption, but also covert communication whose essence lies in concealing data [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Recently, information hiding or data hiding in digital texts, known as text hiding, has drawn considerable attention due to its extensive usage, and potential applications in the cybersecurity and network communication industries [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 5...…”

“…During the last two decades, many text hiding algorithms have been introduced in terms of text steganography and text watermarking for covert communication [ 1 , 6 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 20 , 31 , 36 , 39 , 51 , 91 ], copyright protection [ 3 , 4 , 5 , 7 , 18 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 44 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 72 , 73 , 74 , 75 , 87 , <...>…”
