Copyright Protection Based on Contextual Web Watermarking

Interdependency of information, security and the advent of internet technologies bring more challenges to manage protection against threats like illegal copying, redistribution, tempering, reuse and forgery of online data. Web page is one of the main sources to trade online information and therefore require more protection. In this research a novel tamper proof web watermarking technique based on its textual content has been proposed. Watermarks are generated based on the context and have utilized the structural elements of HTML (Hyper Text Markup Language) to embed the watermarks into a webpage. Watermarks are further secured by a cryptographic technique before the embedding process to integrate more security. Experiments identify the tempered information without revealing any evidence of encrypted watermarks. Proposed system has been tested against different attacks to confirm the robustness and integrity.
