[摘要] 设计了一种基于区块链的电子数据存证系统,该系统充分利用了区块链的去中心化、不可篡改性等特性,将数据关键信息锚定在主链上,同时控制了不同用户对电子数据的访问权限,有效解决了电子数据存证存在的安全问题。为用户提供了数据上传、下载、查询、比对和授权等服务,同时引入了分布式存储技术和用户积分机制,增加系统的可靠性。

[Abstract] An electronic data storage and certificate system is designed in this paper. This system makes full use of the decentralization and non-tampering of the blockchain. The key data information is anchored on the main chain, and the access rights of different users to electronic data are controlled. Thus, the security problems of existing mechanisms are resolved. The system provides users with data upload, download, query, comparison and authorization services. The distributed storage technology and user integration mechanism are introduced to increase the reliability of the system.
