In this paper we present an invisible spatial domain watermarking technique. The technique
divides the image into n small blocks and the intensity of some of these blocks are modified …

In this paper we propose a block based method of image reconstruction which acts as a
generic attack against any block based watermarking scheme in spatial domain. Our …

This paper proposes a methodology in designing a spatial watermark which is robust to
geometrical attacks. The proposed watermarking methodology is based on self-registering …

In this paper, a novel asymmetric public-key watermarking scheme for static images is
proposed. The watermark is embedded with the use of a private key, while the decoding …

A variety of robust non-perceptual watermarking methods have been proposed to solve the
illegal copying and proof of ownership problems. Although a number of broad claims have …

Digital watermarking (DWM) technology has been proposed for the implementation of digital
right management (DRM) system that can be used for establishing ownership right, ensuring …

In this paper, a novel multi-channel image watermarking framework which is able to resist
geometric attacks is proposed, and a spatial domain watermarking scheme which benefits …

We describe a new technique for robust watermarking of digital images for copyright
protection. The proposed technique involves modulating the image signal with random zero …

The rapid growth of digital multimedia technologies brings tremendous attention to the field
of digital watermarking. The owner or the distributor of the digital images can insert unique …

An information theoretic approach is used to hide a visually meaningful and recognizable
two level watermark symbol in the spatial domain. Watermark insertion regions are selected …
