In this paper, we proposed a load balancing digital right management platform based on grid computing (GC-DRM) and compliance of grid portal standards by using porlet. The platform integrates Globus Toolkit 4 and Condor 6.9.2 and uses Web 2.0 to construct the Web-based user interface for providing job submission, control, management, monitor and DRM services. It provides six categories of services, including watermark embedding and extraction, image scrambling, visible watermark embedding, image tamper-detection and recovery, watermark algorithms attack testing, user customized tasks. It can dispatch tasks to remote computers and return results to complete the mission. Therefore, GC-DRM provides a user friendly environment with efficient DRM service performance based on grid computing architecture.
