Privacy Protection Method On User Digital Book Browsing Preferences

With the advent of the new era,the great improvement of human productivity and the rapid development of science and technology,the computer performance we use on a daily basis has also been greatly improved,which dramatically improves the quality and way of our lives,the most representative of which is the popularization of cloud computing and the continuous optimization and improvement of computing performance,So connected and digital life has permeated every corner of our lives,from today's most popular digital currencies(Bitcoin,Wright coins),electronic means of payment(Alipay,WeChat wallets)and the use of the most popular digital library is the best embodiment.However,while the digital age has brought us great convenience,its potential security issues have also been concerned by the general public,of which the main concerns of the security aspects are as follows: 1.Privacy protection of User Content;2.Privacy protection of user behavior;3.Privacy protection of user trajectory;4.Private protection of user status.Therefore,how to protect users ' different browsing methods or different degrees of browsing behavior privacy protection has been a hot topic of research.This paper mainly aims at the privacy protection of the book browsing behavior preference of digital library users,and then designs an effective protection method.Based on the user's historical browsing record,this method proposes to blur and conceal the user's sensitive book browsing preference by constructing a sequence of "true and false" pseudo-behavior in a trusted client,which is mixed with the real behavior of the user,and submitted to the untrusted server side at the same time.This paper mainly verifies the feasibility and effectiveness of this method based on the analysis of the algorithm theory and the experimental evaluation results.At the same time,in the model optimization stage,it is based on the Model security measure and feature similarity measurement results,which makes the overall performance of the model improve.In short,this approach can ensure that the privacy of users ' book browsing preferences can be guaranteed on the server side of untrusted digital libraries without compromising the practicality,accuracy,and efficiency of users ' use of digital library services.Specifically,this article will mainly carry out research work from the following four aspects.(1)User Book Browsing Privacy protection framework: This section mainly describes an overall overview of the privacy protection approach process.Includes the user sending a request to start to the server side to return the request result,and finally the user gets the correct request result and ends.(2)User Book Browsing privacy protection Model: This section mainly describes other requests that,when the user initiates a request,through the privacy protection model,produce a sequence similar to the user structure,but with different semantics.Then when the server returns the result of each request,the user's true request results are filtered out through the privacy protection model.(3)User Book Browsing privacy protection algorithm: This Part mainly describes how the privacy Protection model produces request information similar to that of the user when the user initiates a request to a trusted client,so that the server side cannot correctly identify the user's real request information,so as to achieve the privacy protection effect.(4)User Book Browsing privacy evaluation Model: This part mainly evaluates the feasibility and effectiveness of model privacy protection algorithm in performance and security.(5)User Book Browsing Privacy protection Experiment Evaluation: This part mainly evaluates the experimental effect produced when the algorithm is applied to the actual production,and proves the practical feasibility,efficiency,security and ease of use of the method by analyzing the experimental results.In a word,the work of this paper is mainly a new research attempt to protect the privacy of the user behavior preference of digital library,which is of positive significance for the construction of the overall safe and effective digital library service in the future.
