Abstract:
Privacy is becoming an important concern in service oriented environments like grid and web. Service providers and service requesters, both have complex set of privacy policies to better protect their interests. Both the parties need surety that the facts/information they reveal about themselves will not be used inappropriately by the other. Most of the past models available to address privacy requirements are adhoc, application specific or partially implemented. Some models address privacy concerns of either the requester or the provider. This study proposes a generalized privacy model to handle the privacy requirements of both, the service providers and the service requesters. The model provides a uniform, integrated and platform neutral way to express, store, evaluate, enforce and manage privacy policies. The research also discusses a prototype implementation of the proposed privacy based authorization framework. The implementation has been done in NET environment with the support of WSE 3.0. The prototype implementation has shown that the model is able to meet the identified privacy requirements which suggest that the approach is workable and can be used to provide privacy based access to grid and web services.
