基于区块链技术的数据共享应用发展与挑战

Development and challenge of data sharing based on block chain technology

比特币的横空出世使得区块链技术得到广泛的关注.其高度安全性使其在金融、网络安全和物联网等多方面得到广泛应用.与此同时,数据的爆发增长为数据共享带来了诸多机遇,但是传统的数据共享方法无法应对日益复杂的网络环境以及海量增长的数据.文章论述了五个方面的内容:①分析了将区块链技术应用到数据共享场景中的动机;②总结了将区块链技术应用到数据共享场景中的典型应用架构;③介绍了在智慧医疗、智能交通、智慧城市和供应链管理等领域中的安全存储、访问控制和审计等典型应用;④介绍了基于区块链技术的数据共享机制与人工智能等新兴热点技术相结合的契机;⑤从应用扩展与监管的角度,提出了未来值得研究的方向.

The emergence of Bitcoin makes blockchain technology widely concerned.Its high security makes it widely used in finance,network security,internet of things and other aspects.At the same time,the explosive growth of data brings many opportunities for data sharing,but traditional data sharing methods cannot cope with the increasingly complex network environment and the massive growth of data.This paper covers five aspects:①The motivation of applying block chain technology to data sharing scenarios;②The typical application architecture of applying block chain technology to data sharing scenarios;③The typical applications of security storage,access control and auditing in the fields of smart medical treatment,smart transportation,smart city and supply chain management;④The opportunity of combining the data sharing mechanism based on block chain technology with emerging hot technologies such as artificial intelligence;⑤The future research direction from the perspective of application expansion and supervision.
