Abstract


The development of the Internet makes the digital world in real life more and more influence , on the one hand, advances in technology greatly contributed to the rapid development of the digital content industry , on the other hand , the digital content easily is illegal to copy, modify and disseminate digital content copyright under serious threat . With the development of mobile communication technology and the popularity of mobile phones , mobile communication field also encountered the same problem , how to protect the copyright of digital content has become a serious problem . DRM (Digital Right Management, DRM ) is a new technology developed in order to protect the copyright of digital content through encryption, signing , watermark technology to prevent illegal copying of digital content or increase the cost of replication . OMA DRM Open Mobile Alliance to develop the field of mobile communications digital copyright protection standard , the field of mobile communications is currently the most mature , most participants , the most influential mainstream DRM standards . The contents of this paper is on the basis of high-capacity smart card and smart phone development of the system based on standardized DRM system OMA DRM2.0 - use of the advantages of high-capacity smart card storage capacity and processing speed of the established in the smart card end a specifically belong DRM management profile database for storing the mobile terminal can be obtained digital content corresponding to the Rights Object , while the two special commands existing ISO7816 protocol protocol extensions to create a smart card of the mobile terminal of the present system with large capacity exclusively Room non-standard file read and write into the data channel , so that through this dedicated channel for delivery of the rights object in the mobile terminal and a large-capacity between the smart card . The advantage of this system is that digital content and copyright objects stored separately , namely: digital content stored on the phone , and mutual copy between different phones (via USB, infrared, Bluetooth , etc. ) , and the copyright objects are stored on the SIM can not be shared between different end users . SIM card that uniquely identifies the user's identity , designed both to protect the interests of the content providers to protect the consumer's reasonable consumer rights .
