In this sense, methods (mainly cryptographic methods) have been put in place to guarantee secrecy meaning messages as well signing from certificates. The digital document only defined by its textual content. With rise OCRs, alteration and fraudulent use has increased. work we propose algorithm based on code book secure codebook stores information that uniquely identifies used make correspondence table between elements consider take into account modeling different values are associated with these elements. results our show it quite efficient.
