Within information hiding technology, digital watermarking is one of the most important technologies for copyright protection of digital content. Many digital watermarking schemes have been proposed in academia. However, these schemes are not used, because they are not practical; one reason for this is that the evaluation criteria are loosely defined. To make the evaluation more concrete and im...

a r t i c l e i n f o a b s t r a c t Everyday, we encounter high-quality multimedia contents from HDTV broadcasting, DVD, and high-speed Internet services. These contents are, unhappily, processed and distributed without protection. This paper proposes a practical video watermarking technique on the compressed domain that is real-time and robust against video processing attacks. In particular,...

Digital watermarking is a technology being developed to ensure security and protection of multimedia data. The purpose of digital watermarking is not to restrict use of multimedia resources, but rather to facilitate data authentication and copyright protection. In this paper, we discuss the general requirements on data hiding and digital watermarking. It includes topics in spatial watermarking;...

A digital watermark is a kind of marker covertly embedded in a noise tolerant signal such as audio or image data. It is typically used to identify ownership of the copyright of such signal. "Watermarking" is the process of hiding digital information in a carrier signal. Embedding a digital signal (audio, video or image) with information which cannot be removed easily is called digital watermark...

Digital watermarking involves embedding copyright marks (watermarks ), often imperceptibly, in multimedia objects to enhance or protect their value. In this paper we describe a novel watermarking algorithm suitable for video coding techniques such as MPEG-4 and H.2631.324 and we test it in a wireless environment. The proposed algorithm satisfies critical properties not all of which are availabl...

— A novel video watermarking system operating in the three-dimensional wavelet transform is here presented. Specifically the video sequence is partitioned into spatio-temporal units and the single shots are projected onto the 3D wavelet domain. First a gray-scale watermark image is decomposed into a series of bitplanes that are preprocessed with a random location matrix. After that the preproce...

Abstract Video piracy is a challenging issue in the modern world. Approximately $$90\%$$ 90 % of newly released films were illegally distributed around world via Internet. To overcome this issue, video watermarking an effective process that integrates logo frames as wat...

Hiding details or redundant information is the most preferred way to reduce data complexity. Watermarking techniques areintroduced to serve the purpose and foundusefulin hiding data or information like numbers, texts and images in digital media formats such as Audio, Video and Image.This paper represents the work carried on one of the fragile watermarking techniques i.e. reversible watermarking...

This article addresses the detection of stealthy attacks on sensor measurements. Inspired in authentication schemes with weak cryptographic guarantees, we propose a watermarking approach to validate data and its source. In particular, multiplicative scheme, where outputs are watermarked by bank filters, then transmitted through possibly unsecured communication network. The original measurement ...

Digital watermarking is a method which is used to verify texts, image, video etc. Watermarking Technique is not only used for Authentication, it’s also used for security, image protection, rights of documents. In this perspective experiment we used edge detection technique in watermarking for the purpose of highly authentication of image. Here we used combined approach of LSB-DCT watermarking f...
