The study about digital copyright protectionbased on mobile devices is becoming more and more meaningful.This paper focuses on the copyright protection based on mobile devices. The mainly works arethe following aspects:1．This paper analyzes a secure and traceable E-DRM system based on mobile device putforward by Chin-Ling Chen, and points out the existence of security risks in the system.2．This paper puts forward an anonymous and traceable copyright protection protocol based onmobile devices. The protocol uses transformable temporary identity, one time password, one-wayhash function authentication, copyright watermarking and fingerprint watermark embeddingtechnology. On the basis of ensuring the protocol safety, it achieves anonymity of user to preventillegal tracing, reducing the computation and storage, and tracking the traitor effectively.3．This paper uses the Android development platform to develop a digital rights managementsystem of pictures transaction. Experiment shows that this program is feasible, security andpractical.
