TLDR
A reliable watermark extraction scheme is developed for the extraction of watermark from the distorted images and it is demonstrated that the proposed scheme is able to withstand a variety of attacks.Abstract:
This paper presents a new human visual system (HVS) based adaptive digital watermarking scheme using discrete cosine transformation (DCT) and singular value decomposition (SVD) for copyright protection. For watermark embedding mask of the original image is computed using HVS model and original image is transformed into frequency domain using DCT. We embed watermark by modifying the singular values of DCT coefficient of the original image, by singular values of mask coefficient of original image and singular values of watermark logo. A reliable watermark extraction scheme is developed for the extraction of watermark from the distorted images. Experimental evaluation demonstrates that the proposed scheme is able to withstand a variety of attacks.read more

Secure spread spectrum watermarking for images, audio and video
TL;DR: The watermark can be constructed to make counterfeiting almost impossible, and the same digital watermarking algorithm can be applied to all three media under consideration with only minor modifications, making it especially appropriate for multimedia products.
