Anonymity and fair-exchange in e-commerce protocol for physical products delivery

Fair exchange and customer's and merchant's anonymity are two important properties of e-commerce transactions. There is to date a variety of proposed e-commerce protocols to achieve fair exchange and customer's anonymity for transactions involving digital products. For physical products delivery there is no e-commerce protocol to provide fair exchange and customer's and merchant's anonymity. In this paper, we propose the first e-commerce protocol for physical products delivery that will provide fair exchange in all circumstances, anonymity of customer and merchant for any collusion that can be formed, non-repudiation, integrity and confidentiality of data exchanged between the parties.
