Abstract

The existing data sharing models have some issues such as poor transparency of data transactions, data without security assurance and lacking of effective data tracking methods. This paper proposed a brand-new data sharing scheme based on blockchain technology. Firstly, a blockchain double-chain structure about blockchain was introduced, one chain was used to store the original data and another was used to store transaction data generated by transactions. This structure separated the original data storage and data transactions. Secondly, combined with proxy re-encryption technology, safe and reliable data sharing were achieved. Finally, a new design was implemented. The logical structure of data transaction records enables data to be traced. The results of correctness and security analysis showed that this scheme can provide new technical ideas and methods for big data sharing and data trace.
基于区块链的数据共享与跟踪方案
现有的数据共享模型存在数据交易透明度差、数据缺乏安全保障、缺乏有效的数据跟踪方法等问题。本文提出了一种全新的基于区块链技术的数据共享方案。首先,引入关于区块链的区块链双链结构,一条链用于存储原始数据,另一条链用于存储交易产生的交易数据。这种结构分离了原始数据存储和数据事务。其次,结合代理重加密技术,实现了安全可靠的数据共享;最后,实现了一种新的设计。数据事务记录的逻辑结构使数据能够被跟踪。正确性和安全性分析结果表明,该方案可以为大数据共享和数据跟踪提供新的技术思路和方法。
