Enhanced Technique for Protecting Web Service Composition from Privacy Attack.

Web service composition is a web technology that combines information from more than one source into a single web application. This technique provides a special type of composition application that aims at integrating data from multiple data providers depending on the user’s request. In addition, DaaS (Data as a Service) composition may reveal privacy sensitive information. When enforcing a traditional privacy preserving model, such as privacy model and negotiation, the composed data would suffer from the problem known as the curse of privacy attacks. In this paper is used to propose a new dynamic privacy model with cognitive algorithm in order to extend DaaS composition with privacy capabilities and to enable fast access to data resources on the Web. This dynamic privacy model makes it possible to dynamically reconcile the privacy capabilities of services when incompatibilities arise in DaaS composition. Validate the applicability of proposal through an implementation and a set of experiments.
