A Study on Digital Rights Management System for safety Distributions of Digital Contents
Abstract
A Digital Rights Management (DRM) system has a reproduction control (copy control) function doing functional encryption (encryption) fixed user who encrypts copyright of digital contents for the purpose of protection so as not to be able to know contents of contents only so that functional, access restriction permitting (conditional access) cannot reproduce illegally access and identification and a tracing (identification & tracing) function chase the contents reproduced when contents were reproduced, and to confirm. The existing DRM system tends to limit convenience or flexible business model because DRM system emphasizes protecting content. This is causing inconvenience on user using DRM contents.
This paper presents three types of DRM systems. The first is the DRM system that it is possible for especially support flexible business model through re-issue Rights Object (RO), and the second is the DRM system that can protect copyright about user manufacture contents, the last is the DRM systems that application is possible to Multimedia Messaging Service (MMS). A user makes various free use possible compare with the existing DRM system to use DRM contents through suggested DRM systems, and make copyright protection possible about own direct contents that made. In entrances of contents supplier do compare with the existing DRM so as to be able to establish price policy of more various forms or a sales policy, and can expect so that acceleration to apply DRM at multimedia contents of further a lot of forms through this becomes. Finally, copyright protection about the contents which contents supplier provides to MMS becomes possible, and to develop to MMS of various forms will contribute.
