With wide spread use of digital data communication on networks, security of data has become an important issue which provides integrity and confidentiality of content that ensures the distribution of information appropriately. While dealing with encoded content in the context of XML, its hierarchical tree structure has different level of confidentiality and integrity for various portion of the same content. Thus it imposes the need of dissemination approach specifically tailored for XML data to address the issues of efficiency and scalability. However these characteristics must be achieved without compromising the security and privacy of contents. The goal of efficient proposed Signature scheme for secure & selective distribution of XML content is to provide uniform platform for different data representation for secure and efficient availability of data. Proposed Signature Scheme is used to detect the change of content at information providers to discover and deliver new content to users. This can be achieved using structural properties of hierarchical tree structure data model with multicast topology approach.
