Content-Based Web Watermarking

Abstract

With the increasing growth in internet use, information has turned into e-information and provides a greater freedom for information sharing. This also brings a greater need for information security by protecting copyrights of online authors. A novel tamper proof web watermarking technique has been proposed in this paper that uses the textual features of different languages. Initially three different languages English, Urdu and Arabic have been used in this research for testing and verification, however this idea can be extended to other languages. Watermarks are generated based on language features and further secured by encryption using advanced encryption standard algorithm to ensure another layer of security. Encrypted watermarks have been embedded into HTML page utilizing the structural aspects of markup language. Experimental results have shown that copied information can be recognized by using the proposed system even after modification attacks without requiring the disclosure of watermark information.
