TLDR
A copyright protection method that is based on hiding an ‘invisible’ signal, known as digital watermark, in the image is presented and a variation that generates image dependent watermarks as well as a method to handle geometrical distortions are presented.About:

Digital Watermarking
TL;DR: Digital Watermarking covers the crucial research findings in the field and explains the principles underlying digital watermarking technologies, describes the requirements that have given rise to them, and discusses the diverse ends to which these technologies are being applied.

A steganographic method for images by pixel-value differencing
Da-Chun Wu,Wen-Hsiang Tsai +1 more
TL;DR: A new and efficient steganographic method for embedding secret messages into a gray-valued cover image that provides an easy way to produce a more imperceptible result than those yielded by simple least-significant-bit replacement methods.

An SVD-based watermarking scheme for protecting rightful ownership
Ruizhen Liu,Tieniu Tan +1 more
TL;DR: A novel watermarking algorithm based on singular value decomposition (SVD) is proposed and results show that the newwatermarking method performs well in both security and robustness.
Journal ArticleDOI
Perceptual watermarks for digital images and video
TL;DR: Digital watermarking techniques are described, known as perceptually based watermarks, that are designed to exploit aspects of the the human visual system in order to provide a transparent (invisible), yet robust watermark.

A perceptually tuned subband image coder based on the measure of just-noticeable-distortion profile
Chun-Hsien Chou,Yun-Chin Li +1 more
TL;DR: A new quantitative fidelity measure, termed as peak signal-to-perceptible-noise ratio (PSPNR), is proposed to assess the quality of the compressed image by taking the perceptible part of the distortion into account.

Secure spread spectrum watermarking for images, audio and video
TL;DR: The watermark can be constructed to make counterfeiting almost impossible, and the same digital watermarking algorithm can be applied to all three media under consideration with only minor modifications, making it especially appropriate for multimedia products.

A watermark for digital images
TL;DR: This work describes two techniques for the invisible marking of images and analyzes the robustness of the watermarks with respect to linear and nonlinear filtering, and JPEG compression.
Embedding robust labels into images for copyright protection
Jian Zhao,Eckhard Koch +1 more
TL;DR: A set of novel steganographic methods to secretly embed robust labels into image data for identifying image copyright holder and original distributor in digital networked environment and can survive processing which does not seriously reduce the quality of the image.
