Abstract
The Watermarking is the method of embedding data into digital multimedia content. It is used to verify and recognize the identity of the digital content’s owner. Real time watermarks that are embedded into physical objects like currencies or bills or letter papers are invisible under normal viewing conditions. But if the viewing condition changes, watermark patterns will become visible. Some watermarks can be viewed only if the saturation level of that image is increased. Such type is known as unseen visible watermarking (UVW). In this watermarking method , the 2D images are watermarked by UVW method using Ridgelet wavelet transform to increase the efficiency. The quality of Watermarking is determined by important factors namely robustness, capacity, imperceptibility and blindness.
