A Secure and Efficient Micropayment System
n this paper, we analyze some key issues concerning systems for processing Internet micropayments. At the heart of the matter is the trade-off between security and cost considerations. A set of criteria is proposed, against which a number of previously proposed and currently operational micropayment systems are reviewed. We also propose a model, called WebCoin, embodying a number of innovations that may enhance micropayment systems currently in use.
