Research on E-commerce Payment Security and Privacy Protection Based on Improved B2C Model

The popularity of Internet and mobile terminalspromotes the development of e-commerce. However, e-commercewhich is not necessary to face to face poses a major challenge to thepayment security and privacy protection of consumers. This paperbriefly introduces the traditional business to customer (B2C)e-commerce model. A third-party privacy server was introduced toprovide a double encryption algorithm for the model, and then thetraditional and improved B2C models were simulated to verify theperformance of the two models in the confidentiality of the transactioninformation and the security of the transaction informationtransmission process. The results showed that the intruder could notdirectly obtain the sensitive privacy information such as paymentinformation and order information of consumers even if he invaded thedatabase of the online store when the improved B2C model was used;after the transaction information was intercepted and decrypted underthe two B2C models, the decryption integrity decreased with theincrease of the transaction information quantity, while under the sametransaction information quantity, the decryption integrity of theimproved B2C model was lower
