摘要
随着大数据和云计算的快速发展,借助第三方平台进行数据共享已成为主流模式,但在数据共享过程中容易出现交易双方互不信任、数据被窃取、标识不唯一等问题.针对这一情况,结合区块链技术构建网络数据共享平台,利用区块链集中维护不易篡改、去中心化、数据库可靠等特点,解决数据隐私保护和共享难题.首先,根据网络数据共享难题构建安全模型建立共识机制,继而通过数据加密和访问控制机制保护数据隐私,最终实现网络数据安全、实时共享,构建健康可信的网络环境.通过与其他模型在隐私保护和安全性上进行比较,验证本设计具有较强的实用性.
With the rapid development of big data and cloud computing,data sharing with the help of third-party platforms has become the mainstream model,but in the process of data sharing,problems such as mutual distrust between the two parties in the transaction,easy theft of data,and unique identification are prone.In view of this situation,it is the key to establish a decentralized and privacy-protected network sharing model.This paper combines the blockchain technology to build a network data sharing platform,and uses the blockchain to centrally maintain the characteristics of difficult to tamper with,decentralization,and reliable databases.To solve data privacy protection and sharing challenges.First,build a security model based on the problem of network data sharing to establish a consensus mechanism,and then protect data privacy through data encryption and access control mechanisms.Finally,secure,real-time sharing of network data,and build a healthy and trusted network environment.Compared with other models in terms of privacy protection and security,this design has strong practicability.
