Enhanced user data privacy with pay-by-data model

Personal data collection is becoming pervasive these days, these data has the risk of being abused by current application and application marketplace model, because only the price of application is explicitly indicated without clear agreement on usage of data, and the granularity of data access authentication is not enough to protect users privacy. In this short paper, we propose a new model of user data privacy. Data usage of the application is explicitly shown, and controlled by an authentication service, to protect users from the abuse of their data, especially in mobile application.

I. Introduction

There emerged a large amount of applications, especially mobile applications, harnessing user-generated data, to deliver values to either users or organizations (or both). To distribute these applications, all major platforms now provide their application marketplaces. Although such model has been proven to be easy for user to find and install application, and helpful to prosper the application development, there still exists some important issues including the one we are targeting in this paper: the risk that the application can collect the user data without letting users know. This problem comes from two aspects:
