基于区块链智能合约的大数据安全
BIG DATA SECURITY BASED ON BLOCKCHAIN SMART CONTRACT
摘要
Abstract
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.关键词
