摘要
为提高云存储平台安全性,确保用户数据隐私,通过对比分析现有云平台结构与技术,提出一种基于区块链的加密云存储平台模型。首先,该平台通过IPFS网络实现数据分布式存储,并通过加密技术保证用户数据隐私性;然后利用区块链记录文件存储信息,实现文件存储可公开验证;最后通过区块链智能合约技术保证平台交易公平性。相比于现有云平台,该系统可有效规避数据仅存储于中央服务器的缺陷,文件完整性验证方案可脱离第三方验证机构,有效提高用户数据隐私性。
In order to improve the security of cloud storage platform and the privacy of user data,this paper proposes a block⁃chain-based encrypted cloud storage platform model by comparing existing cloud platform structure and analyzing existing technology.Firstly,the platform realizes the distributed storage of data through the IPFS network,and guarantees the privacy of the user data through the encryption technology.Then it uses the blockchain to record the information about file storage to realize the public verifica⁃tion of the file storage,and then guarantees the fairness of platform trading with smart contracts based on blockchain.Compared with the existing cloud platform,the system effectively avoids the defects that the data is stored in the central server,and the file integrity verification scheme is also separated from the third-party verification organization,the privacy of the user data is effectively improved.
