A Fair-Exchange and Customer-Anonymity Electronic Commerce Protocol for Digital Content Transactions

摘要

This paper devises a new e-commerce protocol that can ensure fair exchange and customer's anonymity for digital content transactions. The proposed protocol considers the complete transaction process: negotiating, withdrawing, purchasing, and arbitrating phases. The offline arbitrator reduces the possibility of becoming a bottleneck. By scrupulous analysis, the proposed protocol achieves fair exchange, customer's anonymity, and good efficiency.
