Secure Knowledge management

April 4, 2007

Problem #1

Describe a application that requires the interoperability between multiple data sources (e.g., records in doctors’ office, hospitals, insurance companies). Develop security policies for interoperability. Show how semantic web technologies may be used to provide secure interoperability.

Problem #2

Describe a geospatial application (preferably in the crime domain or in the national security domain). Show how security policies may be applied to such a application? Is there a need for privacy?

Problem #3

Describe knowledge management for an application (e.g., a corporate environment). Discuss with examples, the need for secure knowledge management for your application.
