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.
