摘　　要：目前,高校数字图书馆用户画像数据管理在数据获取、处理、存储与安全方面存在较大问题,这些问题极大制约了馆方知识服务的可持续发展。发挥区块链技术在数据安全管理方面的比较优势,能够有效解决高校数字图书馆用户画像数据管理的瓶颈制约。文章在分析借助区块链技术增强高校数字图书馆用户画像数据管理效能的基础上,提出了具有可行性的策略建议:依托区块链P2P网络协议来系统获取用户画像数据,利用区块链一致性哈希算法增强用户画像数据处理的实效性,凭借区块链账本模型提高用户画像数据存储效率,通过区块链非对称加密机制严防用户画像数据失窃。At present,a significant bottleneck has got in the way in the management of user portrait data in university digital libraries in terms of data acquisition,processing,storage and security,which greatly restricts the sustainable development of library knowledge services.Giving full play to the comparative advantage of blockchain technology in data security management can effectively solve the problems emerged in the user portrait data management in university digital libraries.Based on the analysis of how to enhance the management efficiency of university digital library user portrait data with the help of blockchain technology,this paper puts forward feasible strategies and suggestions:the blockchain P2P network protocol can be employed to systematically obtain user portrait data;the blockchain Consistent Hash Algorithm is used to enhance the effectiveness of user portrait data processing;the blockchain ledger model is used to improve the efficiency of user portrait data;and the asymmetric blockchain encryption mechanism is used to strictly prevent the theft of user portrait data.
