Providing the access to the privacy data in service oriented domain is  a complex and an essential task in the domain specific environment. W3C also practices the privacy on the DAAS. The objective of the article is to implement a domain specific privacy aware web service composition, which provides the role based access to the DAAS. Here web services are used to retrieve the privacy data using the roles which are assigned to the user. The admin can have the control over the role management. The proposed algorithm finds the relation between the data services and also provides the composite services to fulfill the requirements. We have verified the approach with the sample clinical data set through the experiments and the result shows that the objectives of the system are achieved and the performance of the system is considerably improved.
