Jibran Ahmed Memon, Kamran Khowaja, Hameedullah Kazi · 2008
Establishing hidden communication and conveying information secretly has been of interest since long past ago. One of the methods introduced for establishing hidden communication is steganography. Methods of steganography have been mostly applied on images, audios, videos and text while the major characteristic of these methods are to change in the structure and features so as not to be identifiable by human users. Text documents have been widely used since very long time ago. Therefore, different methods of hiding information in texts (text steganography) are witnessed from the past to the present. In this paper a new approach for steganography in Arabic and Urdu texts is introduced. Considering the existence of harakaat/Araabs i.e. Fatha, Kasra, and Damma in Arabic and Urdu phrases, in this approach, by using Reverse Fatha, information is hidden in the texts. This approach can be categorized under feature coding methods. This method can be used for Arabic/Urdu Watermarking.
