Most watermarking algorithms are either robust watermarking for copyright protection or fragile watermarking for tamper detection. This paper proposes a fragile video watermarking algorithm that has the ability to detect tamper in spatial domains. The original video frame is converted from RGB color space into YCbCr color space, then the chrominance component Cb is partitioned into non-overlapp...

"Watermarking" is one method in which digital information buried a carrier signal; the hidden should be related to signal. There are many different types of watermarking, including traditional watermarking that uses visible media (such as snaps, images, or video), and signal may carrying watermarks. Any can tolerate noise, such audio, video, picture data, have watermark implanted it. A must abl...

There is a need for real-time copyright logo insertion in emerging applications, such as Internet protocol television (IPTV). This situation arises in IP-TV and digital TV broadcasting when video residing in a server has to be broadcast by different stations and under different broadcasting rights. Embedded systems that are involved in broadcasting need to have embedded copyright protection. Ex...

The watermarking of digital images, audio, video and multimedia products in general has been proposed for resolving copyright ownership and verifying originality of content. This paper studies the contribution of watermarking for developing protection schemes. A general watermarking framework (GWF) is studied and the fundamental demands are listed. The watermarking algorithms, namely watermark ...

The progression of Internet services and a variety of storage technologies made video piracy as a rising difficulty principally with the promulgation of media distribution through the internet. Essentially digital watermarking entails in inserting secret signs recognized as watermarks inside video data which can be utilized later for copyright recognition as well as authentication confirmation ...

The reliable evaluation of the performance of watermarking algorithms is difficult. An important aspect in this process is the assessment of the visibility of the watermark. In this paper, we address this issue and propose a methodology for evaluating the visual quality of watermarked video. Using a software tool that measures different types of perceptual video artifacts, we determine the most...

Rapid development in technology has facilitated easy access to data in various domains. Security has hence become a subject of major concern. The paper brings forth a novel approach to embed a robust visible and invisible watermark into video frames, such that the authenticity of the original signal is maintained. Through Digital watermarking scheme, additional information is embedded in the vi...

In this paper we initially provide a new geometric interpretation of additive and multiplicative spread-spectrum (SS) watermarking with repetition coding and ML decoding. The interpretation gives an intuitive rationale on why the multiplicative scheme performs better in front of additive independent attacks, and it is also used to produce a novel quantitative performance analysis. Furthermore, ...

This paper proposes a robust watermarking method for uncompressed video data against H.264/AVC and H.265/HEVC compression standards. We embed the watermark data in the midrange transform coefficients of a block that is less similar to its corresponding block in the previous and next frames. This idea makes the watermark robust against the compression standards that use the inter prediction tech...
