Özet

Digital document watermarking is a widely used technique to prevent the unauthorized reproduction of documents by embedding copyright information. However, with the increasing accessibility of smartphones, the illegal copying and distribution of digital documents have become a major concern for organizations handling sensitive information. In this paper, we propose an enhanced screen-cam-resistant watermarking method designed for real-world data collected from Turkish document images. The method aims to improve security and prevent unauthorized distribution across various document categories, including official reports, permits, certificates, and legal documents used by a private firm in Turkey. The proposed encoder-decoder-based approach achieves a watermark detection success rate of over 99%, demonstrating its effectiveness in real-world scenarios.
