【摘要】 从信息系统数据管理中的数据安全问题入手,对使用区块链和智能合约等相关技术实现数据存证与验证进行了研究。利用以太坊开源项目部署了私有链,开发了相应智能合约,并以此作为数据存证与验证公共服务平台,利用区块链链上数据不可伪造的特性面向第三方信息系统提供数据上链与验证服务,同时对数据存证与验证公共服务链进行了验证。更多还原

【Abstract】 It carries out the research by starting from the data security issues in the data management of information system, in which the main content includes the investigation on the application of block chain and the realization of data storage and verification by smart contract and other related technologies. The Ethereum open source project is used to deploy the private chain. In the meantime, the corresponding smart contract is developed in this thesis, which can be regarded as a public service platform for data storage and verification on this basis. By taking advantage of the features such as the unforgeability of data on the block chain, it can to provide data on the chain and verification services for the third-party information system. What’s more, the paper carries out the test on the public service chain for data storage and verification.更多还原
