Towards Privacy-Aware Web Services Compositions

Privacy is an important issue that has raised particular concerns among many research areas. This issue dramatically increases with the proliferation of the Web services composition paradigm. This is mainly due to the high dynamism and untrustworthiness characteristics of the services to be composed, which impose high levels of risk on the interacting parties. Existing technologies for managing and applying data privacy policies fail to deal with this kind of applications as they involve autonomous entities and continuously exchange huge amount of information of different natures. In this context, this paper tackles the problem of modeling, managing and preserving privacy in Web service composition processes. It aims to design and develop an integrated framework to enhance Web service compositions with privacy protection capabilities taking into account user privacy preferences and privacy policies and requirements of service providers.
