The central idea of this paper is to develop an algorithm that embeds the watermark
information, with out much distortion to the image, while making it possible to extract the …

We have presented an algorithm of digital image watermarking for color images which we
implemented in frequency domain. Before inserting the watermark, we added the Hamming …

Watermarking is a technology that complements cryptography by embedding imperceptible
signals in work. Information hiding techniques have recently become important in a number …

Digital Watermarking embeds identifying information in an image, which is not always
hidden, in such a manner that it cannot easily be removed. This is used to identify the owner …

In this paper, a novel watermarking scheme for color images is proposed. The host image is
transformed from RGB color space to YCbCr color space. First discrete cosine transform is …

Digital watermarking technology is an important means of copyright protection. This article
decomposes RGB for the color image and embeds the algorithm of multiple watermarks in …

A novel scheme for the watermarking of colour images is presented in this communication.
The first objective is to find the most suitable alternative to RGB color space, which is highly …

In this paper we present a blind low frequency watermarking scheme on gray level images,
which is based on DCT transform and spread spectrum communications technique. We …

This letter proposes improvement to the previously presented watermarking method which
spreads an ID pattern with a random sequence and embeds it throughout the spatial domain …
