Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Various mechanisms for authentication and access control have been developed over time. Operating systems and DBMS implement such mechanisms and support quite rich access control models. A major limitation, hover, of such mechanisms is that they are not extensible; thus whenever an application domain requires more sophisticated access controls or authentication, the applications must include logics for such controls. Such an approach leads to increased costs in application development and maintenance. For these reasons, models and mechanisms apt to separate those functions have emerged, also fostered by XML and b services.-At the same time, the need to drive the behaviour of security through clearly stated and machine-processable policies has fostered the development of various policy models and policy management mechanisms. A policy-based approach enhances flexibility, and reduces the application development costs. Changes to the access control or authentication requirements simply entail modifying the policies, without requiring changes to the applications. It is thus clear that an important approach to the problem of security is represented by the development of policy-based security services providing all functions for security management relevant to applications. Such an approach is particularly promising for applications organized according to the Service Oriented (SOA) paradigm.   discuss basic concepts of such an approach to security and  present a reference architectural framework.  discuss three relevant classes of security services, namely digital identity management services, authentication services, access control services, and outline research directions for each such class
