A New Steganography Technique Based on Dotted Arabic Letters Features

Because of the great evolution of communication technologies, the subject of information security has become a sensitive topic that must be given great importance in order to protect confidential information. Steganography is one of the effective ways to improve security and information protection while transferring data over the Internet. It consists of hiding information within an unremarkable cover object that can be either of text, image, audio, or video. Arabic language and other similar languages such as Urdu and Persian, possess some special features that make them excellent covers for steganography. In this work, we propose to use for the first time in the literature, the position of points in dotted Arabic letters combining with other Arabic text features to create a new steganography technique. Based on this idea, we introduce new secret bit patterns that could allow us to hide three bits of secret information into a cover object instead of one bit, and hence greatly enhance the capacity performance. Experiments show the effectiveness of our proposed technique by outperforming other existing steganography methods.
