Improvement and implementation of digital content protection scheme using identity based signature

The progress of the Internet makes enables a consumer to edit contents already exhibited on the Internet and thus create new content as secondary content. However, technology that protects the right of the author of original content in the secondary content is also required. Hence, this study involves proposing a content protection scheme that can control secondary use of content based on the intention of the author by using ID-based signature. The objective of the study involves verifying the practicality of the scheme by mounting it. Therefore, the scheme was applied to contents that were created by using "MikuMikuDance," a content editing tool for 3D CG movies, and a content protection system was mounted. The study illustrated the method, using which this system was mounted and described the evaluation of the processing speed in a simulation environment.
