摘　　要：针对大数据V值性、多个所有者参与、增量水印和大覆盖等因素,提出一种大数据货币化场景中基于区块链和智能合约的大数据水印算法。该算法通过注册阶段获得登录凭证以进行后期身份验证,基于星际文件系统(Interplanetary File System,IPFS)来上传水印数据以解决各种安全问题,采用代理重加密技术进行访问控制以保证数据交易的安全性,智能合约支付系统通过实施规则来确保支付过程中的公平、透明、安全和隐私。实验结果证明了该算法在执行气体成本方面的可行性和有效性,并且不受拒绝服务攻击、中间人攻击和水印攻击等影响。Aimed at factors such as the V-value of big data,participation of multiple owners,incremental watermarking and large coverage,a big data watermarking algorithm based on blockchain and smart contracts in big data monetization scenarios is proposed.The algorithm obtained login credentials through the registration phase for later identity verification,and uploaded watermark data based on the interplanetary file system(IPFS)to solve various security problems.It used proxy re-encryption technology for access control to ensure data transactions.The smart contract payment system implemented rules to ensure fairness,transparency,security and privacy in the payment process.The experimental results prove the feasibility and effectiveness of the algorithm in the implementation of gas cost,and it is not affected by DoS attack,man-in-the-middle attacks and watermark attacks.
