Micropayment, e-commerce, conceptual model, security, hash function.
Micropayments, which are of tiny value and high volumes, are too small to warrant the cost of the current electronic financial transactions. The proliferation of value added content providers over the global information infrastructure, and the easy access to ubiquitous networking certainly demands a micropayment system, which is cost effective, secure and easy to use. In this paper we propose an efficient micropayment system, which is mainly based on simple hash functions and digital signature rather than relying on computationally more complex and costly cryptographic algorithms. The proposed WebCoin system’s architecture and protocols are explained in detail.
