Abstract
Users are often not only interested in the current web page contents but also in changes in it. In this paper we describes web page change detection system based on Signature of Node corresponds to HTML pages. In this proposal first HTML document is filtered into XML structure document and then transforms XML pages to trees using DOM. The node signature comparison algorithm is developed to compare the trees of old web page and modified web page to find the changes in the web page. This system highlights changes of content i.e. deletion and addition of text and attribute changes i.e. font change, caption change, color change etc. and highlight the changed part in red color and displays to the user. This algorithm gets result faster as it does not search the sub tree if that sub tree does not have any changes.
