Consider for example the integration of two information sources. Each information source may utilize a database system to manage the data. Metadata may include information about the types of data in the database as well as ontologies to handle semantic heterogeneity. When integrating the information, the various security policies as well as the schema have to be integrated to provide a uniform view. With respect to collaborating, we need policies for different users to collaborate with one another. How can the participants trust each other? How can trust be established? What sort of access control is appropriate? There is research in developing security models for workflow and collaboration systems [BERT2424]. Secure e-business is receiving a lot of attention. How can the models, processes and functions be secured? What are these security models? Closely related to e-business is supply chain management. The challenge here is ensuring security as well as timely communication between the suppliers and the customers. In this chapter, we will discuss the various security issues for activity management and then discuss the application of Web services and semantic Web technologies.
