Although digital rights management (DRM) has gained increasing importance in today's digital services and electronic commerce, it is not addressed explicitly in the Internet Open Trading Protocol (IOTP) specification. In this paper, we propose a digital rights management system (RMS) that is integrated into IOTP for electronic commerce applications and services. We introduce a rights insertion phase and a rights verification phase for IOTP. In the proposed framework, digital watermarking plays a very important role in facilitating digital rights management. The proposed digital rights management system was implemented on an online music web site and the proposed concepts and approaches proved to be successful.
