现有的传统电子数据存证系统往往存在第三方信任危机、数据安全隐患等问题。为了应对这一挑战,设计实现了一种基于区块链的电子数据存证系统。系统编写智能合约,将数据关键信息锚定在主链上,保证电子数据的不可篡改,同时约束不同用户对电子数据的访问权限。并引入分布式存储技术和用户积分机制,用以增加系统的可靠性。结果表明,系统有效解决了电子数据存证的篡改和安全问题,为用户提供了数据上传、下载、查询、比对和授权等服务。
Abstract：The existing traditional electronic data storage and certificate systems are often encountered with third-party trust crisis and potential data security risks.To cope with these challenges,an electronic data storage and certificate system is designed.In this system,intelligent contracts are compiled to anchor key information on the main chain to ensure non-tampering of electronic data.In the meantime,the access rights of different users to electronic data are restricted accordingly.The distributed storage technology and user integration mechanism are also introduced to increase the reliability of this system.Results show that the system can effectively solve the anti-tamper risks and security problems of electronic data storage and certificate,and also provide users with data uploading,downloading,querying,comparing and authorizing services.
