摘　　要：在大数据领域,数据湖是一种重要的数据共享模式,其引发的隐私保护问题一直是该领域的研究热点,尤其在海上油气开发数据安全方面。为推动有价值的数据流动,需要增强已有的数据湖隐私性和跨域共享的安全性。基于此,本文提出了一种海上油气数据湖架构下的数据访问隐私保护控制技术,以区块链的数据访问和共享模型为基础,优化基于区块链的智能合约。研究结果表明,在可信运行环境下,将Hash值保存到区块链上,既可以达到数据访问控制与安全分享的目标,又可以降低系统吞吐率。In the field of big data,data lake is an important data sharing model,but the privacy protection issues it raises have always been a research hotspot in this field,especially in the field of data security for offshore oil and gas development.To promote valuable data flow,it is necessary to enhance the privacy of existing data lakes and the security of cross domain sharing.Based on this,this article proposes a data access privacy protection control technology under the offshore oil and gas data lake architecture,which optimizes smart contracts based on blockchain data access and sharing models.The research results indicate that in a trusted operating environment,storing hash values on the blockchain can not only achieve the goals of data access control and secure sharing,but also reduce system throughput.
