Abstract
ABSTRACTText steganography is a technique of hiding information within text in a way that prevents detection by unintended recipients. Unlike cryptography, which secures the content of a message by transforming it into an unreadable form, steganography conceals the existence of the message itself. All traditional steganographic techniques have limited ability to hide information. They can hide at most 10% of the cover data. While recent research has predominantly focused on hiding data in images, applying these techniques to natural language text presents greater complexity. Various text steganography algorithms are employed depending on specific requirements. To meet shared demands, it is essential to achieve both high-level concealment and the ability to hide substantial amounts of confidential data. The findings show that field of text steganography is continuously evolving, with ongoing research addressing both traditional and emerging challenges. Numerous studies indicate a strong interest in comparing different techniques to identify the most effective methods. This study suggests combining steganography with advanced encryption techniques or blockchain to create more secure and tamper-proof communication systems and highlights the diversity and depth of research in text steganography, pointing to both current challenges and promising directions for future study.Keywords: Stego, Cover, Security, Steganography, Discrete.I.INTRODUCTIONIn today's world, the internet plays a crucial role in communication and information sharing. However, with the rapid advancements in Information Technology and Communication, data security has increasingly become a concern. Each day, sensitive information is compromised, and unauthorized access to data has reached alarming levels. It is essential to take significant measures to protect this data and information. Combining steganography with encryption offers a powerful and effective solution for ensuring a high level of security.Hmood et al. (2021) stated that steganography is both an art and a science where a message is concealed within another message, making it accessible only to the intended recipient. The term "steganography" is derived from the Greek words "Steganos" (meaning "Covered") and "Graptos" (meaning "Writing"). In the modern context, steganography typically involves hiding information or a file within a digital image, text, video, or audio file. The main purpose of this technique is not to reveal the hidden data to others, but to ensure the data's existence remains undetected.The importance of steganographic applications is especially evident when used with digital images. This combination serves multiple purposes, including copyright protection, feature tagging, and covert communication. The focus of steganography is on ensuring the presence of hidden data without revealing it, making it particularly valuable for scenarios where data concealment and assurance are crucial. The goal of steganography is not to stop others from accessing the secret information, but to prevent them from even realizing that the information exists. In essence, steganography is often referred to as "invisible" communication.Krishnan et al. (2020) observed that text steganography is considered the most challenging form of steganography compared to other types, such as those applied to images, video files, or audio files, due to the limited redundancy of information in a text file.This study reviewed advances made on text steganography based on the methods and problems the addressed as well as their challenges for hiding information. This will assist with valuable technique for enhancing privacy, protecting sensitive information, and facilitating secure communication in both personal and professional contexts.
