Design of a secure architecture for context-aware Web Services using access control mechanism

Services are expected to be a promising way for people to use information and computing resources in our emerging ubiquitous network society and cloud computing environments. Context aware computing attains environment monitoring by means of sensors to provide relevant information or services according to the identified context. In this paper, which explores recent findings in the implementation of Web Services in context-aware areas. The security issues that may surface are identified and methods of countering those security threats are proposed. The main emphasis is the challenge to design effective privacy and access control models for Context-Aware Web Services environment. Hence, there is a need that arises to design a security system for context-aware web services with the support of end-to-end security in business services between the service providers and service requesters. In view of this, a design for secure architecture for context-aware web services is proposed.
