基于联盟链的数字图书馆用户隐私保护研究

Research on User Privacy Protection of Digital Libraries Based on Alliance Chain

通过分析用户隐私信息在用户、数字图书馆和供应商之间的流动路径、生命周期各环节泄露风险,结合三螺旋理论和联盟链技术,构建包含数据层、网络层、共识层、合约层与应用层五个层级的数字图书馆用户隐私保护模型(LibUPM),以期为数字图书馆用户隐私保护提供新的思路和方法,实现用户信息的开发利用与隐私保护之间的平衡。

By analyzing the flow path,link and leakage risk of user privacy information among users,digital libraries and suppliers,combined with triple helix theory and alliance chain technology,this paper constructs a user privacy protection model of digital library(LibUPM)including five levels:data layer,network layer,consensus layer,contract layer and application layer,in order to provide new ideas and methods for digital libraries user privacy protection,and realize the balance between the exploitation and privacy protection of user information.
