By expanding communication, in some cases there is a need for hidden communication. Steganography is one of the methods used for hidden exchange of information. Steganography is a method to hide the information under a cover media such as image or sound. In this paper a new method for Steganography in Persian and Arabic texts is presented. Here we use the special form of “La” word for hiding the data. This word is created by connecting “Lam” and “Alef” characters. For hiding bit 0 we use the normal form of word “La” (“لـا”) by inserting Arabic extension character between “Lam” and “Alef” characters. But for hiding bit 1 we use the special form of word “La” (“لا”) which has a unique code in Unicode standard texts. Its code is FEFB in Unicode hex notation. This method is not limited to electronic documents (E-documents) and also can be used on printed documents. This approach can be categorized under feature coding methods.
