A robust, invisible watermarking scheme is proposed for digital images, where the watermark is embedded using the blockbased lapped orthogonal transform (LOT). The embedding proces...
There are various traditional video watermarking schemes robust to geometrical transformations. Most of them use synchronizing techniques or invariant transforms to resist geometr...

Abstract. In this paper, we propose a watermarking scheme for the image ownership verification in terms of a private key pattern and wavelet filters. The watermarking is mainly ach...
This paper presents a feature-based watermarking scheme which is robust to geometric and common image processing attacks. The improved Harris corner detector is used to find the r...
—The pervasive distribution of digital images triggers an emergent need of authenticating degraded images by lossy compression and transmission. This paper proposes a robust cont...
