IMPLEMENTATION OF NON-INSTALL TYPE DRM SYSTEM TO PREVENT ILLEGAL COPYING OF WEB-BASED MEDIA CONTENT

摘要

With the development of IT technology today, many media content services are being used, and there are cases where they have to use both online and offline depending on the service type. However, there are various difficulties due to illegal distribution of content. In this paper, we study DRM (Digital Right Management) method which can run on a web browser that supports HTML5, which does not need to be installed separately, in order to prevent illegal distribution of media content. The existing DRM method is expensive, and since the encryption algorithm is not standardized even when it is operated off-line, it is difficult to use since a dedicated DRM viewer for each installation type have to be installed. To solve this problem, this paper proposes and implements a new DRM system using base64, an encrypted media source file, which can be used without installing separately in a web browser supporting HTML5.
