摘　　要：为了保护大数据环境中数据库的隐私,提出了一种基于区块链的数据库隐私保护模型.该模型使用分布式区块链来保护敏感数据,并将非敏感数据保存在普通的分布式数据库中.设计了一个数据管理策略以实现数据分配和搜索等操作.提出了用于区块链账本维护的共识协议和随机同态椭圆曲线密码加密模型,以提高数据安全性和效率.实验结果表明,提出的模型能减少数据库搜索时间,改善加密的性能,并且能节省硬盘和处理器资源.In order to protect the privacy of databases in big data environment,a database privacy protection model based on blockchain is proposed.This model uses distributed blockchain to protect sensitive data,and saves non-sensitive data in ordinary distributed database.First,a data management strategy is designed to realize data distribution and search operations.Then,a consensus protocol for blockchain ledger maintenance is proposed,and a random homomorphic elliptic curve encryption model is also proposed to improve data security and efficiency.The experimental results show that the proposed model can reduce the database search time,improve the performance of encryption,and save hard disk and processor resources.
