Enhancement of most significant bit (MSB) algorithm using discrete cosine transform (DCT) in non-blind watermarking / Halimah Tun Abdullah

Digital watermarking is used to protect the intellectual property from malicious attack. This is because everyday people easily take the images or download the images without permission from ownership. Digital watermarking can hide data, such as in image, video and audio. In this project, the image...
