A Privacy Protection Model for Electronic Commerce Process

摘要

Since there are privacy leaks in the process of traditional e-commerce, we present a model to protect user's privacy in which we make an improvement on trusted third party for achieving this goal. Then, the identity authentication can be done through the trusted third party and other sites can use the unique user identification code allocated by the trusted third party to ensure user's identity. We also present a triple signature verification algorithm in which the transaction account information in the whole process is only available to the bank, the real contact information can only be obtained by the shipping company, and the purchases information can only be received by the business. With the proposed one-time receipt algorithm, we can sign using the unique user identification code instead of the user's real name and can use double acknowledgements in the payment process. In comparison between our new model and some existing models, experiments show that our new model is more secure and thus can protect user's private information more effectively.
