As the logistic environment of digital contents is rapidly changing, the protection of digital rights for digital content has been recognized as a very critical issue that needs to be dealt with effectively. Digital Rights Management (DRM) has taken much interest in Internet Service Providers (ISPs), authors and publishers of digital content in order to create a trusted environment for access and use of digital resources. In this paper, PKI (Public Key Infrastructure) and a licensing agent are used in order to prevent illegal use of digital contents by unauthorized users. In addition, a DRM system is proposed and designed which performs proprietary encryption and real-time decoding using the I-frame-under-container method to protect copyright of video data.
