Mahdi Soodkhah Mohammadi, Abbas Ghaemi Bafghi

摘要:

在线业务的主要考虑因素之一是客户隐私。消费者对被卖家监视和识别不感兴趣。一些解决方案被提出来隐藏客户的选择,但在支付阶段,将有一个泄漏的信息,因为在线购物者可以推断一些信息,客户的偏好,由于价格,这是由客户支付。这是对客户隐私的巨大威胁。我们解决这个问题的方案包括一些一个单位的支付步骤,不能相互联系或客户的身份。在购买结束时,内容提供方将收到适当数量的钱,而客户将匿名获得有效的许可证。内容提供方将无法获得有关客户或所购买内容的任何信息。此外,一个纠纷解决方案的情况下,客户和内容提供方之间的冲突。对方案的安全性、复杂性和DRM要求进行了一系列的分析,表明了方案的安全性和实用性。

英文摘要:

One of major considerations in an online business is customer privacy. Consumers are not interested in being monitored and identified by sellers. Some solutions are proposed to hide selection of the customer but in the payment phase, there will be a leakage of information as online shopper can infer some information about customer's preference due to the price, which is paid by customer. This is a big threat to customer privacy. Our solution to this problem consists of a number of one-unit payment steps that cannot be linked to each other or to customer's identity. At the end of purchase, content provider will receive appropriate amount of money while customer will acquire a valid license anonymously. Content provider will not be able to gain any information about the customer or the content that is purchased. In addition, a dispute resolution scheme is presented for cases of conflict between customer and content provider. A series of analyses on the security, complexity and DRM requirements are presented which indicate security and practicality of our scheme.
