An XML-Based Data Integrity Service Model for Web Intermediaries
Recent research in active network and web intermediary services result in web contents being disassembled, transformed and recomposed in a pipelined process as they flow through the Internet. This makes the web pages more vulnerable than they were ever before. Thus, there is an urgent need for a formal model to define and protect data integrity of web contents. This paper proposes a Data Integrity Service Model (DISM). DISM is an XML language designed to be interposed into markup to preserve data integrity of the web contents. It allows the content owner to express their intentions, in terms of permissions, as part of the response message.
