A method and system for protecting privacy of browsing preferences of digital library users

Abstract

The invention discloses a browsing preference privacy protection method and system of a digital library user. The method includes the following steps: (1) acquiring a book browsing request submitted by the user, constructing a group of book browsing pseudo-requests, which are similar to the book browsing request submitted by user, according to a historical book browsing request sequence of the user, a historical book browsing pseudo-request sequence set and a book classification level tree, and submitting the same to a digital library server end; and (2) acquiring request results returned by the server end, filtering corresponding request results, which is in the returned request results and of the book browsing pseudo-requests, to obtain a corresponding request result of the book browsingrequest submitted by the user, and feeding back the same to the user. The system includes a book browsing request submitting module and a request result screening module. The method and the system can ensure security of book browsing preference privacy of the user at the untrusted digital library server end on the premise of not impairing practicability, accuracy and high efficiency of digital library services.
