In the era of big data, the application of the database is very extensive, and the implementation of many laws is inseparable from the application of the database [1]. According to General Principles of the Civil Law of the People's Republic of China and Consumer Protection Law of the People's Republic of China, this paper finds the loss of consumer information in the current online transactions. In order to study the feasibility of the legal provisions, this paper applies the PPSDS (Privacy Protection in Secure Database Service) database model and the DPSASA (the Database Protection System Against SQL Attacks) database model [2][3]. The former realizes the reasonable preservation of information by decomposing the original database. The latter achieves the defense against SQL attacks by filtering the violation characters in the request, thereby achieving the purpose of protecting the information. At the same time, this paper draws on the advantages of EU law and related policies, and combines the above two models to propose an optimization plan to protect consumer information in online transactions.
