Audio Watermarking with Multiple Images as Watermarks
IETE Journal of Education, 2020Nowadays, the security of information has become a burning question. Digital watermarking can be very efficient in providing security of a signal being sent. In this paper, a digital watermarking technique for ensuring security to an audio signal is presented.

Framework for digital video watermarking with dual watermarks
SPIE Proceedings, 2002This paper presents a video watermarking scheme for copyright notification and protection. Each video frame is clustered into high motion and low motion regions. Dual watermarks are designed by exploiting video motion, perceptual characteristics, and some other informative cues.

ACM SIGMETRICS Performance Evaluation Review, 1980
Historically, benchmark tests have been one of several ways to size a computer system, and measure its performance. Today, it is more important to test the System Software than the machine hardware. (Thus the term "watermark" (as on bond paper) for software tests.) Watermarks of software suffer the same limitations and risks as benchmarks of hardware ...

IEEE Signal Processing Letters, 2004
In this letter, we propose a new asymmetric watermarking system which can accommodate many embedding watermarks but needs only one reference watermark for detection. Such a system is useful in averting attacks that seek to estimate the embedding watermark.

A Watermarking Scheme in the Encrypted Domain for Watermarking Protocol
2008In most watermarking schemes for copyright protection, a seller always knows the embedded watermark identifying a buyer. However, it incurs both repudiation issue and framing issue. To solve these problems, many watermarking protocols have been proposed based on watermarking schemes in the encrypted domain.

Design of Secure Watermarking Scheme for Watermarking Protocol
2007Watermarking technique enables to hide an imperceptible watermark into a multimedia content for copyright protection. However, in most conventional watermarking schemes, the watermark is embedded solely by the seller, and both the seller and the buyer know the watermarked copy, which causes unsettled dispute at the phase of arbitration.

Improved Differential Energy Watermarking for Embedding Watermark
2006Digital watermarking is increasingly demanded for protecting or verifying the original image ownership. In this paper, we propose an improved differential energy watermarking using adaptive differential energy watermarking (ADEW) with cross binding wavelet tree (CBWT).

Adaptive Watermarking Algorithm for Binary Image Watermarks
2004This paper proposes an adaptive watermarking algorithm, in which the watermark is a binary image such as a logotype related directly to the image owner. Obviously the information amount of this type of watermark is much larger than the amount of a pseudorandom pattern generated by secret key.

Joint halftoning and watermarking
IEEE Transactions on Signal Processing, 2000A spread spectrum watermarking algorithm for hardcopy imaging applications using a human visual system model based halftoning technique called direct binary search (DBS) is presented. DBS is used to design a halftone that jointly optimizes a human visual system based error metric and correlation watermark detector output. The original image is required
