Abstract

Internet purchase is increasing according to the activation of Electronic Commerce. Currently, the hardware is main purchase items in the Electronic Commerce. The on-line purchase of digital product, that is electronic file type of product, has many merits such as, does not cost in logistics, is ease of searching the product, and is possible of ''Try and Buy'' system. But, actually digital products have not been major product because of its piracy problem. The piracy problem of digital products comes from the lack of safety in DP license control technology. Current EC has no method to identify the object that has the right to use the digital product. The protecting of object change is impossible and the protection of hacking is not enough and EC has many problems in efficient license control because of the incompletion of EC structure. In this paper, we propose the design and implementation of on-line DP circulation system, which can activate on-line circulation of DP in EC and protect its piracy, by using the new license control technology, that is Dynamic License Control technology.
