Digital watermarking is the process of conveying information by imperceptibly embedding it into the digital media. Benchmarking is used to evaluate the watermarking algorithms. Different benchmarks are available for digital watermarking. These benchmarks work efficiently but they are complex, difficult to understand, so a new benchmark is introduced in his paper which is GUI (Graphical user int...

Benchmarking digital watermarking algorithms is not an easy task because different applications of digital watermarking often have very different sets of requirements and trade-offs between conflicting requirements. While there have been some general-purpose digital watermarking benchmarking systems available, they normally do not support complicated benchmarking tasks and cannot be easily reco...

In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...

Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...

A problem of considerable theoretical interest in digital watermarking is that of asymmetric, or zero-knowledge watermarking. In this problem, we wish to embed a watermark in a piece of multimedia and later prove that we have done so, but without revealing information that can be used by an adversary to remove the signal later. In this paper we develop a watermarking system based on the ambigui...

Watermarking is a technique, which is used in protecting digital information like image, video and audio as it provides copyrights and ownership Audio watermarking is more difficult than image watermarking than image watermarking due to the dynamic supremacy of hearing capacity over the visual field. Digital watermarking is a technique by which copyright information is embedded into the host si...

Calculation of watermarking capacities of private Laplacian watermarking systems with the magnitude-error distortion measure under fixed attacks is addressed. First, in the case of an additive Laplacian attack, a nice closed-form formula for the watermarking capacities is derived, which involves only the distortion level and the parameter of the Laplacian attack. Second, in the case of an arbit...

Digital watermarking is a good tool for healthcare information management systems. The wellknown quantization-index-modulationQIMbased watermarking has its limitations as the host imagewill be destroyed; however, the recovery ofmedical image is essential to avoidmisdiagnosis. A transparent yet reversible watermarking algorithm is required for medical image applications. In this paper, we propos...

Digital watermarking protocols are the one, which have combined fingerprinting technique with watermarking, for embedding digital signal or watermark into an original multimedia object. Buyer-seller watermarking protocol is fundamentally applied to continue the digital rights of both buyers and seller. We proposed an identity-based buyer-seller watermarking protocol that encounters various weak...
