Due to the ever increasing number of web services available through the Internet, the privacy as a fundamental human right is endangered. Informed consent and collection of information are two important aspects while interacting on the Internet through web services. The ease of data access and the ready availability of it through Internet, made it easier for interested parties to intrude into the individual's privacy in unprecedented ways. The regulatory and technical solutions adopted to curb this have achieved only a limited success. The main culprits in this regard are the incompatibilities in the regulatory measures and standards. This research work focuses on privacy preserving access control for sharing sensitive information in the arena of web services, provides some recent outlooks towards the critical need of privacy aware access control technologies and a comprehensive review of the existing work in this arena. Besides, a novel framework for privacy aware access to web services is also provided.
