Content Self-Protection for Digital Products Using RFID-Enable Agent Platform

There are lots of protection technologies which protect digital products such as audio, video, and software. We believe that the protection systems using software/hardware based cryptograph have no fault themselves. Nevertheless, these technologies were circumvented shortly after their release. We argue that the reasons are because there are three inevitable factors in current protection system. The first is that people casually share the key, and this shared key is always valid for the same products. The second is that current system cannot distinguish the ordinal and the replica because both can provide the same functionalities and thus it allows people to extract the contents from physical media. The last is that all digital products can be reproduced using their devices. Therefore, this paper proposes a novel approach for the protection of digital products using RFID and agent technologies to resolve these problems.
