VLSI implementation of a real-time video watermark embedder and detector

چکیده
This paper describes the hardware design and implementation of the JAWS (Just Another Watermarking System) embedder and detector for watermarking of realtime uncompressed digital video. Our design employs a Roating point datapath, maximizing dynamic range of the FIT, frame filtering, and correlation operations. The design, implemented in a l.SV, 0.18pm CMOS process with a core area of 3.53 mm2, is capable of watermarking video streams at a peak rate of over 3 Mpixels/s.

Secret Key Watermarking with Changing Keys
In this paper we consider a digital watermarking application where multiple parties can embed additional information using their watermark embedder. These parties are not supposed to influence each other and each watermark detector needs to be able to decode the information embedded by any of the embedder systems. One approach would be to use a single secret key and to assign part of the payloa...
متن کاملA Practical Real-Time Video Watermarking Scheme Robust against Downscaling Attack
In this paper, we propose a practical real-time video watermarking scheme for downscaling attack. We embed watermark into an arbitrary size of a host video and extract it from the watermarked video under a preset false error rate. Both watermark embedding and extraction are done in the uncompressed domain. Also, blind detector is used (i.e., no original video needs during the detection). As our...
متن کاملRobust track-and-trace video watermarking
With the development of computers and the Internet, digital multimedia can be distributed and pirated easily. Watermarking is a useful technique for multimedia copyright protection. In this paper, we develop a robust video watermarking system. It consists of two components, i.e., watermarking embedder and watermarking detector. In the embedder, we insert a watermark pattern into video frames ac...
متن کاملInformed Embedding: Exploiting Image and Detector Information During Watermark Insertion
Usually watermark embedding simply adds a globally or locally attenuated watermark pattern to the cover data (photograph, music, movie). The attenuation is required to maintain fidelity of the cover data to an observer while the watermark detector considers the cover data to be “noise”. We refer to this as blind embedding. In [1], it was observed that the cover data is not noise, i.e. it is not...
متن کاملWatermark Embedding and Detection
The popularity of Internet access has enabled the wide spread of digital multimedia contents in the form of image, video and audio; however, it also makes unauthorized copying and distribution easier. Researchers from both the industry and the academy have been trying to address this dilemma by watermarking techniques. Watermarking, as a prospective weapon against piracy, embeds ownership infor...
