Enforcing Privacy in Secondary User Information Sharing and Usage

摘要

Secondary user information sharing and usage for purposes other than what it was primarily collected for has become an increasing trend, especially, as we witness a surge in the volume of data collected from and about users online. Although, allowing secondary sharing and usage of data in new and innovative ways is beneficial to the user and the society at large, it also poses the privacy risks of sharing and using personal information for unintended purposes. This paper discusses my PhD thesis towards creating a privacy framework for secondary user information sharing. The aim is to develop an infrastructure that enables sharing of user information across applications and services for beneficial purposes, while balancing it with protecting the user against the potential privacy risks. This paper discusses current work and open challenges.
