Method and system for detecting consistency of privacy data usage purposes in mobile applets

Abstract

The application discloses a kind of mobile applet in privacy data use purpose consistency detection method and system, the method extracts privacy data and use purpose from applet privacy protection guide according to the two types of sentence pattern structure of privacy declaration, obtains the use purpose category table of different privacy data based on clustering;Then extract the static features related to privacy data from applet code, train the use purpose multi-classifier based on static multidimensional features, predict the actual use purpose of privacy data by use purpose multi-classifier;Finally, through consistency model, analyze the consistency between the use purpose of privacy data and actual use, detect the potential privacy risk in applet;By analyzing the two types of sentence pattern structure of applet privacy declaration, the extraction accuracy and efficiency are improved;By defining three kinds of inconsistent privacy disclosure in applet, the privacy disclosure risk in applet privacy protection guide is detected from multiple dimensions, and the detection is more comprehensive and accurate.
