Abstract

Web based distribution of multimedia digital content has been accelerated due to the increase in the use of the Internet. The major issue regarding the design of a multimedia digital content distribution system through the web is to guarantee the security of digital content and to supply a large amount of high quality multimedia digital content to users. This study focused on designing a security technique for each group in a multilayered structure, and on a caching technique, which is based on this security technique, and to improve the user's response speed. Using these techniques guarantees the security of digital content distribution. We implemented the prototype and verified the performance of the proposed system through testing.
