An Intelligent Three-Level Digital Watermarking Method for Document Protection

Digital text is the most frequent interchange form of data that could hold sensitive information such as audit firms, banks, and educational institutes. This needs to preserve its integrity originality so it not only secure but also helps identify ownership documents. paper presents a novel invisible digital watermarking approach for exchange documents over internet. serves from last decade detection forgery tempering maintained copyright authentication successfully. Many states art watermark techniques achieve high imperceptibility, robustness, hidden capacity; unfortunately failed maintain balance among these three conflicting parameters. As resolvent, we propose an intelligent Three-Level Watermarking (3LDW) system protection. 3LDW can be applied Microsoft Word objects, document open spaces, feature coding without affecting content original document. Experimental results reveal our proposed strongly resist against formatting attacks efficiently preserves imperceptibility. Additionally, embedding capacity analysis demonstrates prominent improvement compared other similar approaches.
