Study on Library Individualized Information Security Under the Background of Big Data

Under the background of big data, the issue of users' individual needs are increasingly prominent. This paper analyzes the potential information security problems of library users and finds that their individualized information is easy to be leaked, falsified or lost in the process of information collection and mining. To solve these problems, this paper has proposed an improved data encryption/decryption architecture to effectively improve the defense security of the system and shorten the data processing time as much as possible, and discussed the influence of different factors on the time consumption of information camouflage/information extraction to solve the data privacy security problem from the technical level.

I. Introduction

Following the revolution in personal computers and the Internet, cloud computing, as the representative of the third wave of informatization, is coming to us [1]. Meanwhile, education has entered a new era of reform, and the individualized development of higher education is imperative. For colleges and universities, the main role of the library is to provide literature and information resources for teaching and scientific research to meet the information needs of their teacher and student users [2]. Therefore, the rapid development of cloud computing technology has brought great changes to the traditional operation mode, and user needs of university libraries. The integration of cloud network in the sharing of resources between universities and institutional libraries can promote information exchange, and provide strong technical support for individualized services of university libraries. Technically, private data such as readers' reading behavior, identity information, personal preferences and social relations are collected, integrated, analyzed and mined online to realize the tracking service and demand forecast for readers, which has become the key for libraries to change service modes according to readers' needs and improve service effectiveness, user satisfaction and market competitiveness.
