内容摘要

Abstract: With the enormous popularity of smartphones, millions of mobile apps are developed to provide rich functionalities for users by accessing certain personal data, leading to great privacy concerns. To address this problem, many approaches have been proposed to detecting privacy disclosures in mobile apps, but they largely fail to automatically determine whether the privacy disclosures are necessary for the functionality of apps. In this talk, we will introduce LeakDoctor, an analysis system that integrates dynamic response differential analysis with static response taint analysis to automatically diagnose privacy leaks by judging if a privacy disclosure from an app is necessary for some functionality of the app. Furthermore, we will present the design, implementation, and evaluation of a context-aware real-time mediation system that bridges the semantic gap between GUI foreground interaction and background access, to protect mobile apps from leaking users' private information.
