去中心化的征信系统模型研究
Research on Decentralized Model for Credit Information System
摘要
Abstract
In order to reduce the security caused by single point failure and malicious tampering in data storage of modern credit system, we design a credit system model based on the blockchain storage structure and decentralized characteristics for the hidden dangers such as over-centralization and forgery of data storage. By encrypting the address information of the stored data in the blockchain body, using the broadcast to store the nodes in the entire network, and obtaining the most consistent blockchain of the entire network when verifying the data, the reliability of the information is ensured. The experiment shows that the user's private data is stored in the storage node, and the address information of the storage node is written into the encrypted block body after the cooperation verification of the whole network check node, ensuring the privacy of the data. During data validation, the latest copy from the entire network is updated locally, ensuring that the data is not maliciously manipulated by third parties. Storing sensitive data of the user by the blockchain architecture can greatly improve data security and ensure storage efficiency.关键词
