Digital audio, video, images, and documents are flying through cyberspace to their
respective owners. Unfortunately, along the way, individuals may choose to intervene and …

A digitally altered photograph, often leaving no visual clues of having been tampered with,
can be indistinguishable from an authentic photograph. As a result, photographs no longer …

Visible watermarking schemes are important intellectual property rights (IPR) protection
mechanisms for digital images and videos that have to be released for certain purposes but …

A reversible (also called lossless, distortion-free, or invertible) visible watermarking scheme
is proposed to satisfy the applications, in which the visible watermark is expected to combat …

Visible watermarking is a widely-used technique for marking and protecting copyrights of
many millions of images on the web, yet it suffers from an inherent security flaw …

A visible watermark may convey ownership information that identifies the originator of image
and video. A potential application scenario for visible watermarks was proposed by IBM …

Reversible visible watermarking (RVW) is an active copyright protection mechanism. It not
only transparently superimposes copyright patterns on specific positions of digital images or …

Pixel based scaling of a watermark image is of paramount importance to make the degree of
marking applied variable according to the features of host images. In this study, a wavelet …

A novel method for generic visible watermarking with a capability of lossless image recovery
is proposed. The method is based on the use of deterministic one-to-one compound …

The reversible visible watermark which serves as the perceptual ownership identifier can be
extracted to losslessly recover the original cover media. This paper presents a novel content …
