Implementation of a Trust-Behavior Based Reputation System for Mobile Applications

The sharp increase of the number of mobile applications attracts special attention on mobile application trust. It becomes more and more crucial for a user to know which mobile application is trustworthy to purchase, download, install, execute and recommend. This paper presents the design and implementation of a trust-behavior based reputation system for mobile applications based on an Android platform. The system can automatically evaluate a user's trust in a mobile application based on application usage and generate application reputation according to collected individual trust information. We implement the system and evaluate its performance based on a user study. The result shows that our system is effective with regard to trust/reputation evaluation accuracy, power efficiency and system usability.
