Abstract

Anonymity of the customer and each merchant is a key property that must be considered in a fair exchange e-commerce protocol. The customer may not want to reveal sensitive data of his identity (as credit card number, information about customer’s bank, customer’s account number) so that this information can not be used by merchant in commercial purpose to build spending habits of the customer. Also, a merchant may want to remain anonymous. For example, a merchant who has business in many areas may want that his customers can not link transactions where the merchant is involved in all these areas. In our previous work [4], a fair exchange e-commerce protocol for complex transactions in that a customer wants to buy several different physical products from different merchants is proposed. This solution provides customer anonymity, non-repudiation, integrity and confidentiality of data exchanged between the parties. In this paper, we extend the solution from [4] obtaining both anonymity of customer and each merchant, while preserving all properties obtained in [4].
