Data Processing System Based on Network Security

This paper studies a data processing method, system, device and computer readable storage medium. The method includes: user terminal sends query request to data storage blockchain; the data storage blockchain querying the target information corresponding to the request based on the smart contract; the user terminal displaying the target information and sending the transaction request to the corresponding merchant terminal based on the smart contract. The merchant terminal executes the transaction operation corresponding to the transaction request. And when the transaction operation is completed, it executes the point issuance operation for the account information corresponding to the transaction request based on incentive points. This paper can realize the transaction operation in the e-commerce platform system through the blockchain technology, and store commodity data (target information) through the data storage blockchain. It also ensures the security of various data in the e-commerce platform system, avoid the leakage of private data in the e-commerce platform system, and improve the data credibility and data security of the e-commerce platform system.
