随着大数据时代的到来,敏感数据的安全问题已成为影响图书馆大数据应用的关键因素,图书馆对敏感数据的保护需求与日俱增。文章从完整性、机密性和可用性三方面对图书馆敏感数据的保护进行了研究,分析了大数据环境下图书馆敏感数据的安全需求,设计了一种贯穿数据全生命周期的敏感数据分析与可视化管理系统平台。该系统可确保图书馆敏感大数据安全、高价值、可用和可控。 With the advent of the big data era, the security of sensitive data has become a key factor that affects the application of big data in libraries. The library has a growing demand for the protection of sensitive data. This paper studies the protection of sensitive data in library from the aspects of completeness, confidentiality and usability, analyzes the security requirements of sensitive data in big data environment, and designs a sensitive data analysis Visual management system platform. The system ensures library-sensitive big data is secure, valuable, available and controllable.
