Towards Secure Content Based Dissemination of XML Documents

Collaborating on complex XML data structures is a nontrivial task in domains such as the public sector,healthcare or engineering. Specifically, providing scalable XML content dissemination services in a selective and secure fashion is a challenging task. This paper describes a publish/subscribe middleware infrastructure to achieve a content-based dissemination of XML documents. Our approach relies on the dissemination of XML documents based on their semantics, as described by concepts that form an interoperable description of documents. This infrastructure leverages our earlier scheme for protecting the integrity and confidentiality of XML content during dissemination.
