Secure Pixel Transformation Based Wavelet ImageWatermarking System

Securing the data or an image over the internet today becomes the most concerned topic. For proper utilization of bandwidth over the network, image is compressed prior to sending over the internet. To make sure that the image delivered from one end to the other end is free from intentional or unintentional attacks, we embed the watermark to the image. Watermark does not affect the size of the image, but increases the robustness of the image. This paper proposed a method to secure the wavelet based image watermarking through pixel replacement.
