“…By comparison, the Arabic language uses points, word diacritics, and Kashida. For the English language, as seen in [40,[44][45][46]53,55], various language attributes are used, such as the font, capital and lower-case letters, double letters, high-frequency letters, punctuation, and other symbols. Secret messages are also hidden according to the shape of the English capital alphabets by dividing the letters into groups depending on the letter's shape (curved, vertical, horizontal, etc.).…”

“…Regarding the Indian language, as used in [53], the Indian letters are divided into eight groups based on how they are pronounced (based on the articulation of letters), and then the secret message bits are hidden inside the cover text letter based on the specific positions of the cover text letter bits, according to the shape of the alphabets. (The shapes can be divided into curves, vertical, horizontal, etc.…”

There has been a persistent requirement for safeguarding documents and the data they contain, either in printed or electronic form. This is because the fabrication and faking of documents is prevalent globally, resulting in significant losses for individuals, societies, and industrial sectors, in addition to national security. Therefore, individuals are concerned about protecting their work and avoiding these unlawful actions. Different techniques, such as steganography, cryptography, and coding, have been deployed to protect valuable information. Steganography is an appropriate method, in which the user is able to conceal a message inside another message (cover media). Most of the research on steganography utilizes cover media, such as videos, images, and sounds. Notably, text steganography is usually not given priority because of the difficulties in identifying redundant bits in a text file. To embed information within a document, its attributes must be changed. These attributes may be non-displayed characters, spaces, resized fonts, or purposeful misspellings scattered throughout the text. However, this would be detectable by an attacker or other third party because of the minor change in the document. To address this issue, it is necessary to change the document in such a manner that the change would not be visible to the eye, but could still be decoded using a computer. In this paper, an overview of existing research in this area is provided. First, we provide basic information about text steganography and its general procedure. Next, three classes of text steganography are explained: statistical and random generation, format-based methodologies, and linguistics. The techniques related to each class are analyzed, and particularly the manner in which a unique strategy is provided for hiding secret data. Furthermore, we review the existing works in the development of approaches and algorithms related to text steganography; this review is not exhaustive, and covers research published from 2016 to 2021. This paper aims to assist fellow researchers by compiling the current methods, challenges, and future directions in this field.

“…In the feature coding method [15], the letters are shortened or stretched in terms of their dimension, in addition to changing many text attributes such as color. A random sequence of characters [16] that generated a random string in addition to single letters which is contains the same letters like what in the cover. The inter-sentence space method [17] utilizes spaces between sentences in order to hide the message.…”

Cryptography and steganography are significant tools for data security. Hybrid the cryptography with Steganography can give more security by taking advantage of each technique. This work has proposed a method for improving the crypto-stego method by utilizing the proposed dictionary method to modified ciphertext then hiding modified encrypt ciphertext in the text by used the proposed modified space method. For cryptography, we have been utilized an advanced encryption standard (AES) to the encrypted message, The AES algorithm is utilized a 128bit Block Size and 256bit key size. The ciphertext characters is then replaced by the characters identified by dictionary list. The dictionary is time-dependent, where each of the equivalent words will shifting based on the time-shift equation. The modified ciphertext is then embedded into a cover text so that the attacker cannot separate them by applying cryptanalysis. The â€œModifying Spacesâ€ method used â€œSpacesâ€ to build a steganography tool that hide the secret message. The experimental results show that the proposed method has achieved high-security level when combined cryptography and steganography in such way that the ciphertext is changed to another value by a used dictionary with time sequence that makes cryptanalysis test failed to guess and identify the algorithm that been used for encryption. The stego. test shows the proposed method achieved good results in term of capacity and visibility which is approved it hard to notice. The tests also approved that the proposed methods run fast with a less computational requirement.
