Web Service Security Through Business Logic

Service Computing has recently gained significant momentum to enable the IT services and computing technology to perform business services more efficiently and effectively. Presently the service computing concentrates on inventing and establishing business models which leads to better QoS driven targeting services. So replacing existing business model by QoS driven business model would be the future preference of service computing environment. Further, the most critical and challenging part of web service computing is handling of non functional aspect that may occur during service composition and service execution process. There are many non-functional aspects are involved during service composition and execution at run time. One such a business model solution is called Business Logic Model (BLM) which is proposed in this paper, the primarily aim is to design and implement the business logic for functional and non functional aspect targeting successful service computation. One of the important feature of this model is to manage exceptions occurs during service composition in execution time. The distinct ability of the proposed model is managing the runtime exception is proved with the help of a set of QoS parameters that are especially satisfying the service computational criteria such as computability, traceability, security and decidability.
