基于Schnorr签名的隐私保护网上订购方案

The privacy of users must be protected in e-commerce According to the theory of oblivious transfer, this paper proposed an online order of digital products scheme which could effectively protect the user' privacy through OSBE based on Schnorr signature. First, the user paid the bank correctly and anonymously, and got the digital signature of the product he would order. Then the user interacted with the merchant obliviously through electronic signature, the user could only get the product he ordered. The example shows that the scheme can effectively protect the user's privacy information and prevent the merchant malicious fraud.
