Bhattacharya, J: Privacy Middleware for Preserving Privacy i

In this book, a solution has been developed for mitigating privacy violation in databases, as per legislative requirements. The solution consists of three primary elements that are (a) the privacy middleware, (b) the privacy access layer and (c) the privacy violation detection and monitoring. In this book, the first implementation of the middleware is done in a modified P3P. The work delves into the current areas of research in privacy and proposes a classification of the various areas of work in privacy. It further points out those areas that are particularly relevant from the perspective of the privacy legislations. The privacy policy enforcement layer, presented in this book, is based on EPAL rather than the modified P3P that was originally developed in the absence of an acceptable privacy enforcement language. It further presents a modified SQL to cater to the privacy requirements for managing privacy constrained records. The solution also ensures that privacy violation does not occur from within an organization by those who have direct system/ database access. This is ensured by a clever usage of encryption. The privacy middleware follows a multi-layer approach.
