Description

Technical Field

[0001] The present invention belongs to the field of network security technology, and more specifically, particularly relates to a smart contract privacy protection system based on blockchain. Background Art

[0002] Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traceability", "traceability", "openness and transparency", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation and created a reliable "cooperation" mechanism. In the current corporate transaction process, blockchain is often used as the basis for establishing a contract privacy protection system. However, common privacy protection systems generally have a relatively single function. As data continues to be uploaded to the chain, it is easy to generate various new vulnerabilities, which affects the privacy protection effect. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to use the security testing module in conjunction with the data detection module to find out whether new vulnerability problems have occurred, and to cooperate with the data retrieval unit and the data verification unit in the data retrieval module to ensure the integrity of the on-chain data information, so as to ensure the overall privacy protection effect.

The blockchain data management platform includes an API interface layer, a Baas service layer, a blockchain data layer, a blockchain network layer and a blockchain consensus layer. The database server is electrically connected to the control terminal through a serial port. The control terminal uploads data to the blockchain data management platform through the database server in cooperation with the wireless communication module.

[0006] The database server is provided with a security testing module and a data detection module, wherein the security testing module includes a script detection unit, a virus detection unit and a vulnerability detection unit, and the data detection module includes a data retrieval unit and a data verification unit.

[0007] Preferably, the control terminal includes an alarm module. When the data loss or damage occurs when the uplink data is detected by the data retrieval unit and the data verification unit, the information is synchronized to the control terminal through the database server, and finally an alarm is issued by the alarm module.

[0008] Preferably, the data detection module and the security testing module operate independently of each other, perform periodic security tests and data detection according to staff presets, perform real-time integrity detection on the on-chain data, and cooperate with the attack test result data to achieve the effect of regularly repairing vulnerabilities.

[0009] Preferably, the API interface layer includes a data management interface, the Baas service layer includes an account management unit, the blockchain data layer includes a data block unit, the blockchain network layer includes a privacy protection unit and a permission control unit, and the blockchain consensus layer includes a pos unit and a pool verification pool unit.

[0011] Preferably, the blockchain network layer provides a privacy protection unit to protect the verified user information and contract entry information of the data uploaded to the chain in the database server, and uses the permission control unit to perform encryption processing during the upload process, and decrypts it separately through the blockchain network layer when the contract information needs to be retrieved.

[0012] Preferably, the BaaS service layer is based on the idea of ​​services in the cloud computing architecture and provides blockchain services. The BaaS service is located between the four infrastructure layers of the blockchain, namely the blockchain data layer, blockchain network layer, blockchain consensus layer, and blockchain contract layer, and the API layer, and includes encryption and decryption services and smart contract services.

[0013] Preferably, the database server is configured as a control device based on 5G communication equipment, and both the database server and the control terminal are equipped with a broadband cluster module, which can interact and modify information data in real time according to needs.

[0014] Technical effects and advantages of the present invention:

[0015] The present invention establishes a database server to cooperate with the control terminal to execute the chain-up action, and adds a security test module and a data detection module in the database server. After the data is uploaded to the chain, the staff can set it so that the security test module and the data retrieval module can periodically perform detection actions, and use the script detection unit, the virus detection unit and the vulnerability detection unit to test the data block to find out whether there are new vulnerability problems, and cooperate with the data retrieval unit and the data verification unit in the data retrieval module to ensure the integrity of the uploaded data information, so as to ensure the overall privacy protection effect.
