摘　　要：数据海啸时代移动图书馆用户画像数据面临严峻的服务困境与应用困境,并极大地制约了移动图书馆知识服务的覆盖面与纵深度。发挥区块链技术在去中心化登记、透明化交易、自治性存储与私密性防护等方面的技术优势,可有效化解移动图书馆用户画像数据获取、处理、存储与安全问题。本文在论述利用区块链技术提升移动图书馆用户画像数据管理绩效可行思路的基础上,提出了兼具可操作性与适用性的实践策略:基于区块链P2P网络协议实现用户画像数据全面采集,基于区块链一致性哈希算法提高用户画像数据处理的可靠性与效益性,基于区块链账本模型促进用户画像数据实时共享,基于区块链非对称加密机制规避用户画像数据泄露风险。In the era of data tsunami, user portrait data of mobile library is faced with severe service and application difficulties, which greatly restricts the coverage and depth of knowledge service of mobile library. By giving full play to the technological advantages of blockchain technology in decentralized registration, transparent transactions, autonomous storage and privacy protection, it can effectively solve the problems of user portrait data acquisition, processing, storage and security in mobile libraries. Block chain technology is used in this paper improve mobile library users portrait data management performance, on the basis of feasible thinking, this paper puts forward both feasibility and applicability of practice strategies: based on P2 P network protocol for user portrait block chain, the comprehensive data sampling based on hash algorithm to improve the user portrait chain the exploration data processing of the reliability and efficiency, based on the book block chain model to promote user portrait real-time data sharing, asymmetric encryption mechanism based on block chain around user data information leakage risk.
