Abstract : The World Wide Web provides an information delivery infrastructure for various types of digital contents used in daily life. Payment infrastructures such as digital cash, micropayments, and encrypted credit cards have also been established. However, no digital medium or infrastructure that prevents duplicate redemption and enables the trading of various rights, much like paper tickets, has been established yet. We are thus developing a generalized digital ticket system that can circulate any type of rights. A digital ticket is a digital medium that guarantees certain rights of the ticket owner and it includes software licenses, resource access tickets, event tickets, plane tickets, etc. In this paper I propose a prepaid smart metering scheme for Smart Grid application based on centralized authentication and charging using the WiMAX prepaid accounting model with push technology as an enhancement and providing more security with flash based 2D color barcode.
