چکیده
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 of the work, to authenticate the content, to trace illegal copies of the work. So many digital image watermarking techniques have been implemented to stop the illegal used of digital content. This correlation based watermarking techniques use for generation of visible watermarked image. In this paper, check robustness of correlation based detection watermarking schemes using White Gaussian Noise (WGN) against different Order Statistics Filters Attack in Spatial Domain. The robustness of the Watermarked images has been verified on the parameters of PSNR (Peak Signal to Noise Ratio), NCC (Normalized Cross Correlation) and NAE (Normalized Absolute Error).

Watermarking has increased dramatically in recent years in the Internet and digital media. Watermarking is one of the powerful tools to protect copyright. Local image features have been widely used in watermarking techniques based on feature points. In various papers, the invariance feature has been used to obtain the robustness against attacks. The purpose of this research was based on local f...
متن کاملIntelligent scalable image watermarking robust against progressive DWT-based compression using genetic algorithms
Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...

Wavelet filters can be parametrized to create an entire family of different wavelet filters. We discuss wavelet filter parametrization as a means to add security to wavelet based watermarking schemes. We analyze the influence of the number of filter parameters and use non-stationary multi-resolution decomposition where different wavelet filters are used at different levels of the decomposition....

The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...

The performance of watermarking schemes based on correlation detection is closely related to the frequency characteristics of the watermark sequence. In order to improve both detection reliability and robustness against attacks, embedding of watermarks with high-frequency spectrum, in the low frequencies of the DFT domain, is introduced in this paper and theoretical analysis of correlationbased...
