摘　　要：物联网在我国第一、第二、第三产业中得到大规模应用,物联网设备(如摄像头)产生了海量的图像、视频类多媒体数据,其所蕴含的价值日益得到重视。但在面向数据增值互通、有偿共享这一新需求背景下,传统第三方进行物联网数据交易方案存在隐私泄露、安全性不足等弊端,并且在交易过后数据确权问题也成为影响市场活跃的重要因素。本文利用区块链可溯源、防篡改等技术特性实现物联网数据的安全交易,将物联网数据安全交易转化为两阶段Stackelberg博弈,使用双链架构保障交易过程的安全性和隐私保护,同时使用感知哈希技术实现数据确权,最大程度保障交易中各参与者权益。经实验验证,本文方案在时间、TPS以及零知识证明上均有提升,且使用两阶段Stackelberg博弈后能优化利润分配,进一步验证了本文方案的优势和可行性。对本文方案可能存在的安全威胁进行分析,结果显示本文方案在不同场景下能够有效抵抗合谋攻击、抵赖与陷害风险。The Internet of Things(IoT)has been widely applied in the primary,secondary and tertiary industries in China.IoT devices(such as cameras)have generated a huge amount of image and video multimedia data,and the value contained in it has been paid more and more attention.How to meet the new demand of value-added data exchange and paid sharing and build a safe and fair data transaction mechanism is one of the important foundations of data element value exchange.In view of problems such as privacy leakage and lack of security in the scheme of using traditional third parties to conduct Internet of Things data transaction,this paper realizes secure transaction of Internet of Things data by using technical features such as traceability and tamper-proof of blockchain,and turns security transaction of Internet of Things data into two-stage Stackelberg game.The double-chain architecture is used to ensure the security and privacy protection of the transaction process,and the perceptive hash technology is used to realize data right confirmation,so as to protect the rights and interests of all participants in the transaction to the greatest extent.The improvement of the proposed scheme in time,TPS and zero-knowledge proof,as well as the trend of optimal profit distribution after two-stage Stackelberg game are verified by experiments,further verifying the advantages and feasibility of the proposed scheme.Finally,the possible security threats of this scheme are analyzed,and it is proved that the scheme can effectively resist the risks of collusive attack,denial and frame-up under different scenarios.
