Analysis of Most Unexpected Permissions for Android Apps
Our team has been analyzing Android apps for unusual behaviors, using crowdsourcing techniques to find differences between what people expect an app to do and what an app does in reality. Here are the top 10 most unexpected permissions, based on our crowdsourcing approach to analyze the behavior of Android apps. Each circle represents the level of surprise people had for each permission (N=20). For example, a vast majority of people (95%) were surprised that Brightest Flashlight used location data, but no one (0%) was surprised that Google Maps did so. Here, we can use level of surprise as one form of privacy. If people aren't surprised, then from our perspective it's less of a privacy issue, since people have some level of informed consent. On the other hand, if lots of people are surprised, then we have a potential privacy issue at hand. Click to zoom Here is the top 10 list in text form, with links to more analysis where available.
