A Novel Arabic Text Steganography Method Using Letter Points and Extensions


Adnan Gutub and Manal Fattani


AbstractThis paper presents a new steganography approach suitable for Arabic texts. It can be classified under steganography feature coding methods. The approach hides secret information bits within the letters benefiting from their inherited points. To note the specific letters holding secret bits, the scheme considers the two features, the existence of the points in the letters and the redundant Arabic extension character. We use the pointed letters with extension to hold the secret bit ‘one’ and the un-pointed letters with extension to hold ‘zero’. This steganography technique is found attractive to other languages having similar texts to Arabic such as Persian and Urdu.
