A Dynamic Multi-Layer Steganography Approach Based on Arabic Letters’ Diacritics and Image Layers

Abstract

Steganography is a widely used technique for concealing confidential data within images, videos, and audio. However, using text for steganography has not been sufficiently explored. Text-based steganography has the advantage of a low bandwidth overhead, making it a promising alternative for protecting sensitive information. Among languages, Arabic is known for its linguistic richness, making it ideal for text-based steganography. This paper proposes a robust, dynamic, and multi-layered steganography approach that uses text, encryption algorithms, and images. This approach utilizes Arabic diacritic features to hide limited-size and highly classified information. The algorithm uses several scenarios and is extensively tested to ensure the required level of security and user performance. The experimental results on actual data demonstrate the robustness of the proposed algorithm, with no noticeable impact on the carrier message (original text). Furthermore, no known potential attack can break the proposed algorithm, making it a promising solution for text-based steganography.

“…Robustness: is the capability to prevent unseen data from being damaged, particularly when it is transferred via an unsafe network [19], [20]. Security: The level of security performance that prevents a third party with no connection to the sender and receiver from detecting the existence of a concealed message embedded in the text during the steganography process [19], [20]. Capacity: The amount of information in the covert message can be concealed by embedding it within the text.…”

“…Capacity: The amount of information in the covert message can be concealed by embedding it within the text. During text steganography, the capacity values could be classified by size bit, amount bit, and text length [19], [20].…”
