Preventing Fake Web Pages Using Push Delivery - Defending against Theft Crawlers

摘要

We propose a fake web prevention system based on a push delivery system implemented with a mobile agent on the Web. Web content can be easily replicated using a crawler that automatically retrieves all contents of visited web sites. A rigger reuses content collected by crawlers without authorization. Our fake web prevention system is based on channelizing and imaging original web pages. Channelizing means that our system replaces important HTML tags with channels, then sends the replaced HTML tags into the channels by push delivery. Push delivery is a mechanism that allows the replacement of Web-page content without reloading the page. Imaging means that our system renders a variety of contents on a web page as a single image, which is called an imaged content. Crawlers cannot automatically extract original images from the imaged content. We describe how to implement a fake web prevention system by using push delivery based on a mobile agent. Our system can be used to obstruct reproduction of phishing sites.
