Research Of Privacy Protection Method For Mobile Intelligent Terminal Location Information

With the rapid development of smart mobile devices and location technologies, LBS has been widely used in mobile applications. By using geographic information in these applications, users can get more personalized and targeted services. However, this will also lead to privacy challenges of user location information.To solve the metioned problem, this paper proposes a Location Privacy Protection System for Smart Mobile Terminal, which is divided into two subsystems:LBS Mobile Application Privacy Information Protection System focused on solving the location privacy leak problem while using LBS mobile applications, Picture Resources Location Information Protection System is mainly to solve the EXIF image file location privacy leak problem.During mobile application installation,LBS Mobile Application Privacy Information Protection System makes judge to determine the default location precision settings by analysing applications and users, the core part of this subsystem is the decision tree algorithm. In this paper, we improved the traditional ID3 algorithm and then did some experimental verification; Picture Resources Location Information Protection System can identify the type of image when user taking pictures, its core is content-based image recognition and analysis techniques of EXIF file formats. For this subsystem, we also did experiments to verify results.
