Abstract:
Content delivery via web pages or sites are becoming increasingly popular due to the effectiveness and versatility of the readily available delivery mechanism, especially in the e-education and training. While the copyright laws are there to protect the ownership and commercial rights of the intelligent properties, the openness of the web architecture often makes it impossible to prevent the content source being misappropriated or incorporated illegitimately elsewhere after some modifications on the downloaded source. We propose here an obfuscation mechanism for the HTML5 to convert a site of raw content into a site of obfuscated pages and images. With the advent of canvas on HTML5 and the AJAX to stop certain unauthorized access, the whole site of documents can be rendered meaningless or useless on both the server and the client side if just a small key part is modified or hidden. Several masquerading algorithms have been proposed for this purpose. The obfuscation will become permanent if a webpage is merely downloaded or even DOM-saved without having all necessary intermediate data or keys tracked by a specialist, before the auto-expiry of such a process, at a cost tantamount or exceeding the reconstruction of the original documents from scratches hence defeating the purpose of piracy. We applied the scheme to the delivery of a university subject by automating the whole process.
