Framework for the next generation of e-commerce by peer-to-peer contact: Virtual Private Community

This paper proposes a new framework called Virtual Private Community (VPC) for the next generation e-commerce, in which users buy and sell products by peer-to-peer contact. VPC enables e-commerce to be carried out by employing simple definitions called policy packages. VPC offers extended e-commerce transactions that enable flexible e-commerce services by transferring policy packages together with copyright protection information on users' products. VPC provides a new method in which users can start their businesses by using the simple definitions.
