Rethinking App Permissions on Ios.

To protect against misuse, mobile operating systems require apps to seek user permission before accessing their personal data. While this measure gives users control, they are often asked for their data without knowing who the data will ultimately be shared with, why, and how often. This paper presents results from the evaluation of a proof-of-concept permission manager for iOS that allows users to adjust privileges granted to apps, substitute their personal data with mock data, and review data that has been transmitted to a server.
