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 …

As a major method for intellectual property right protecting, digital watermarking techniques
have been widely studied and used. But due to the problems of data amount and color …

It is generally believed that spatial domain watermarking methods are not robust against
common image processing attacks. In this paper, a novel application of an unsharp mask is …

With the rapid development of computer technology, the copyright protection of color image
is becoming a more and more urgent problem. In this paper, an improved color image blind …

In this paper, we proposed the digital watermarking for a color image. In order to embed
watermark signal, we consider the characteristics of HVS (human visual system) and focus …

In this paper, a new watermarking scheme based on the multi-channel image watermarking
framework is proposed, which is mainly used to resist geometric attacks. The multi-channel …

In this paper, we have proposed a new multiple image encryption and watermarking
technique. Several gray images can be watermarked in the three channels of an enlarged …

It has great significance for protecting the image copyright with color image digital
watermarking technique, which needs the watermarking algorithm has high robustness …

This paper presents a novel spatial data hiding scheme based on the Least Significant Bit
insertion. The bitplane decomposition is obtained by using the (p, r) Fibonacci sequences …

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 …
