Abstract
Digital Watermarking has attracted researchers’ attention because of its useful applications, and over the past two decades, great efforts have been made to develop digital watermarking techniques and algorithms. Most researches use different transform techniques to enhance the robustness and quality of extracted watermark. This paper introduces the digital watermarking with Discrete Pascal Transform (DPT) which gives good results with experiments against various attacks. The attacks that are examined are noise, compression and rotation.
