Data Hiding on Social Media Communications Using Text Steganography

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

“…In the Unicode, there are special zero-width characters (ZWC) which are employed to provide specific entities such as Zero Width Joiner (ZWJ), e.g., ZWJ joins two supportable characters together in particular languages, POP directional, and Zero Width Non-Joiner (ZWNJ), etc. Practically, the ZWC characters do not have traces, widths or written symbol in digital texts [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 11 , 15 , 18 , 25 , 26 , 27 , 28 , 33 , 34 , 41 , 42 , 43 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 ,…”

“…Large media companies are not expected to go away overnight, nor will the demand to communicate by smartphone or meet people in person, but social media provides one more means of engaging with users on this enormous planet, and if employed effectively could give all a more desirable option in how to live and communicate to each other in the digital world. Since the text message in the form of SMS, chat, email, and so on, has become a popular and easy form of communication, concerns about data leakage attacks, such as hacking, hijacking, and phishing, have emerged [ 1 , 6 , 8 , 11 ]. Table 2 lists the text character limitation of social media and messenger apps which support the Unicode standard to process digital texts in different languages (except for ‘Twitter’ and ‘Telegram’).…”

“…to access sensitive information during data transmission. 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 ...…”

“…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 , <...>…”

“…In [101], authors have first encrypted the secret message using 'Data Encryption Standard' (DES) algorithm. Here the cover is dynamically generated from the Hexadecimal character of encrypted message using a predefined look up table substitution.…”
