This paper presents a composition method for document image used in electronic commerce using RDM algorithm. It is possible to compose about double quantity of document image in same document space compared with RL or DM algorithm, if it used. RDM algorithm is available to compose secret document as well as digital signatures onto non-secure document. In this case, secure transmission of document will be realize because the third party do not recognize secure transmission.
