An invisible watermarking technique for image verification
TL;DR: A new method for invisibly watermarking high-quality color and gray-scale images intended for use in image verification applications, where one is interested in knowing whether the content of an image has been altered since some earlier time, perhaps because of the act of a malicious party.
Patent
Protecting images with an image watermark
TL;DR: In this article, a robust means of watermarking a digitized image with a highly random sequence of pixel brightness multipliers is presented, which is formed from robust-watermarking-parameters selected and known only by the marker and/or the marking entity.
Patent
Color correct digital watermarking of images
TL;DR: In this article, a system for placing a visible watermark on a digital image is disclosed, wherein an image of the watermark is combined with the digital image, and for each pixel whose value is not a specified "transparent" value, the corresponding pixel of the original image is modified by changing its brightness but its chromaticities.
Patent
Invisible image watermark for image verification
TL;DR: In this paper, the authors propose a system consisting of a stamping process that embeds stamping information into a source image and produces a verification key, and a verification process that extracts stamping from a stamped source image based on the verification key.
Proceedings ArticleDOI
Effective and ineffective digital watermarks
TL;DR: A number of proposed image-watermarking application scenarios are described and form a small number of watermark-application categories, and the desired technical properties of watermarks for each category are discussed.
