Research And Design Of Mobile DRM System

With the mobile communication technology developing and the number of mobile users growing, wireless value-added services is becoming the focus of the development of mobile communication business. However, under the current network environment, copyright infringement cases often occur.3G increases the convenience of copyright infringement. While we provide these services, we have to face the problem which how to protect the rights of digital products providers,how to ensure the market healthy development. Therefore, we need effective DRM (Digital Right Management) technology to solve the above problems.We combine the WPKI technology and digital watermark technology and propose the solutions for the digital rights management in mobile communications.This article detailed design the functional blocks which system is required.Research and design the business processes and packaging formats of the digital content and digital rights.In this program, we add the AES, ECC, SHA-1 cryptographic coprocessor and the protection unit and other hardware modules in the client part,it create a credible security environment, enhance system security and improving the availability.The program uses WPKI authentication, smart card authentication, password restricted multi-level integrated authentication technology.Given the current physical limitations, this article used the digital watermarking technology in the simulation tests. From the tested result,we can see that digital watermark has little effect for the digital content, digital watermark can be used in practical applications under the present conditions.
