Writing system in the Arabic language consists of (Basic letters), also called (Consonants), (diacritics) to adjust the meanings of words and the application of grammatical rules to express words and phrases, and (Punctuation Marks( . Diacritics are written in the text optionally. Several sets of characters (Fonts) are developed to write Arabic text files, these sets differ in forms and belong to the multiple kinds of computer fonts. They all represent attempts to accommodate the Arab : Character and the characteristics of the Arabic language. The proposed method in our research aims to add watermarks to the electronic Arabic text files, allowing the owner to prove his ownership of the document in front of the judiciary. This is: • Coding method by view and hide diacritics sequentially. The research studied font representation and its components in computer, and the characteristics of diacritics representation in Arabic font sets in computer in particular.
