Today detectability of Intellectual Property in the digital world is a major issue. And a watermarking is one of them process to secure intellectual rights of digital assets. In our paper we propose a method to insert multiple watermark in spatial and frequency domain to make our assets secure and undetectable by dividing our host image into two regions, called region-A and region-B. In a region-A,...

The proposed method enhance the imperceptibility and robustness of LSB technique. In proposed method, results are compared with the existing LSB technique. It uses only one image in place of two images because watermark is self-generated from the host image. To enhance the imperceptibility of watermarked image, a very less pixel valued watermark image is used to embed in host image which is generated...
