A Proposal of An Information Flow Checking System for Android Application

Abstract

Recently, Android are becoming popular smartphones OS. Android applications re- quire permissions to access personal information or device resources. If application has multi permissions which have a combination of network connectivity with personal information acces- sibility, can transmit it across the network. In this paper, we propose a monitoring application to detect leakage of personal information which is caused by these applications. Our method inspects the application outgoing trac and performs fine-graded information control flow to avoid unintended leakage.
