Demo: RecDroid: An Android Resource Access Permission Recommendation System

Nowadays, it is prohibitive for apps market places, such as Google App Store, to thoroughly verify an app's resource permission requests to be legitimate or malicious. As a result, mobile users are left to decide for themselves whether an app is safe to use or not. To assist users to make correct decisions as for whether to accept a permission request or not, we propose RecDroid. RecDroid is a crowdsourcing recommendation framework that collects apps' permission requests and users' responses to those requests, from which an experts ranking algorithm is used to seek expert users in the system and a recommendation algorithm is used to suggest appropriate responses to permission requests (accept or reject) based on experts' responses. In this demo, we demonstrate a user case to show how the RecDroid system assists users in permission control. We also explain the major principles and processes behind that support the RecDroid recommendation system.
