DESCRIPTION:Application markets have revolutionized the software download\
 nmodel of mobile phones: third-party application developers offer\nsoftwar
 e on the market that users can effortlessly install on\ntheir phones. This
  great step forward\, however\, also imposes some\nthreats to user privacy
 : applications often ask for permissions that\nreveal private information 
 such as the user’s location\, contacts and\nmessages. While some mechani
 sms to prevent leaks of user privacy\nto applications have been proposed b
 y the research community\,\nthese solutions fail to consider that applicat
 ion markets are\nprimarily driven by advertisements that rely on accuratel
 y profiling\nthe user. In this paper we take into account that there are t
 wo parties\nwith conflicting interests: the user\, interested in maintaini
 ng\ntheir privacy and the developer who would like to maximize their\nadve
 rtisement revenue through user profiling. We have conducted\nan extensive 
 analysis of more than 250\,000 applications in the Android\nmarket. Our re
 sults indicate that the current privacy protection\nmechanisms are not eff
 ective as developers and advert companies\nare not deterred. Therefore\, w
 e designed and implemented\na market-aware privacy protection framework th
 at aims to achieve\nan equilibrium between the developer’s revenue and t
 he user’s privacy.\nThe proposed framework is based on the establishment
  of a\nfeedback control loop that adjusts the level of privacy protection 
 on\nmobile phones\, in response to advertisement generated revenue.
