“…Therefore, a new watermarking approach called zero-watermarking has been proposed in which the quality of the original image does not change, but the watermark is constructed by extracting features of the original image. Recently, a group of zero-watermarking methods have been introduced [4,5,6,8,9] that extract some binary features from the host image. Then by applying exclusive-or between these extracted features and the binary logo, a verification map is achieved.…”

“…This scheme is not robust enough under some geometric attacks. A new wavelet-based zero-watermarking algorithm was proposed in [5] that achieved better robustness than [4] by applying a kind of smoothing filter on t-level LL subband. An adaptive approach proposed in [6] which allowed image owners to adjust the strength of watermarks through a threshold by using Sobel technology [7].…”

“…Although this method has high performance on non geometric attacks, it still does not achieve high performance for geometric attacks such as rotation and shearing. In this paper, we use discrete wavelet transform and a normalization procedure to extract binary features and compare our scheme with [4], [5] and [9] schemes.…”

Abstract. Recently, protecting the copyright of digital media has become an imperative issue due to the growing illegal reproduction and modification of digital media. A large number of digital watermarking algorithms have been proposed to protect the integrity and copyright of images. Traditional watermarking schemes protect image copyright by embedding a watermark in the spatial or frequency domain of an image. However, these methods degrade the quality of the original image in some extend. In recent years, a new approach called zero-watermarking algorithms is introduced. In these methods, the watermark does not require to be embedded into the protected image but is used to generate a verification map which is registered to a trusted authority for further protection. In this paper a robust copyright proving scheme based on discrete wavelet transform is proposed. It uses a normalization procedure to provide robustness against geometric distortions and a cellular automaton for noise robustness. Experimental results on images with different complexity demonstrate that our proposed scheme is robust against common geometric and non geometric attacks including blurring, JPEG compression, noise addition, sharpening, scaling, rotation, and cropping. In addition, our experimental results obtained on images with different complexities showed that our method could outperform the related methods in most cases.

This paper presents a robust blind frequency domain watermarking scheme based on chaotic maps. The proposed scheme embeds a black and white watermark logo in the midband components of a host image according to a discrete wavelet transform. Each watermark bit is embedded into a small submatrix of selected second level subbands of an image resulting from iterated applications of a two‐dimensional discrete wavelet transform. This scheme embeds two copies of the watermark using two different methods, in two different subbands of the image. At the cost of embedding capacity, this results in improving the security and robustness of the watermarking scheme. Experimental results demonstrate that the suggested scheme provides imperceptibility and robustness against image processing attacks such as JPEG compression, low‐pass filtering, median filtering, Gaussian noise, scaling, rotating, cropping, histogram equalization, and gamma correction. Experimental results also show superior robustness of the suggested scheme over existing algorithms with a similar approach. Copyright © 2013 John Wiley & Sons, Ltd.
