Design of Robust Business-to-Business Electronic Marketplaces with Guaranteed Privacy
提出一种电子市场设计，将交易隐私控制权从市场运营者转移到每个交易者，确保交易完全隐私且不被运营者利用，同时保证交易完整性和不可否认性。
Firms that set up electronic marketplaces to enhance their supply and/or distribution channels face challenges in attracting their competitors to participate. A major obstacle is the perception that the owner can unfairly exploit trading information for competitive advantage. In this paper, we propose a marketplace design that shifts the locus of control over trader privacy from the marketplace operator to each individual trader. We show how online transactions between trading partners can be conducted in total privacy, so that not even the marketplace owner/operator can exploit transaction information for strategic purposes. At the same time, our approach includes robust methods for transaction integrity and nonrepudiation, as well as posttransaction dispute resolution.
