Executive Summary

Content-Based Publish-Subscribe (CBPS) is a widely used communication paradigm where publishers "Publish" messages and a set of subscribers receive these messages based on their interests through filtering and routing by an intermediate set of brokers. CBPS has proven to be suitable for many-to-many communication offering flexibility and efficiency in communications between a dynamic set of publishers and subscribers. The authors are interested in using CBPS in healthcare settings to disseminate health-related information (drug interactions, diagnostic information on diseases) to large numbers of subscribers in a confidentiality-preserving manner.
