The book "Web Document Protection Technique Using Unicode" offers a comprehensive analysis and innovative approaches to digital document security. In an era where internet access facilitates the dissemination of digital content, protecting against unauthorized copying and distribution is crucial. The work highlights the importance of watermarks as an effective means against piracy and introduces the technique of text watermarking, which allows ownership information to be embedded in digital content without compromising its quality. The author, Raj Jaiswal, presents a novel method for implementing text watermarks in web documents that enhances the invisibility and robustness of the embedded watermarks. The technique presented involves three essential processes: generation, embedding, and detection of watermarks, employing an innovative approach that distinguishes it from traditional methods.
