Quality is subjective. Quality can be objectified by the industry standards process represented by such consumer items as compact disc (“CD”) and digital versatile disc (“DVD”). What is lacking is a means for not only associating the creation of valued intangible assets and extensions of recognition but establishing responsibility for copies that may be digitized [...]

Abstract
During the last decade, the availability of information in digital form has increased dramatically. Digital media have numerous advantages over analog media, such as higher quality, easy editing, loss less copying, and fast and efficient distribution. These advantages allow for new [...]

ABSTRACT
Digital Watermarking and data hiding have gained popularity in recent years as a means of protecting digital images from theft, illegal copying and unlawful reproduction. Some digital watermarking algorithms were proposed using spatial domain and transform domain techniques. The transform domain could be DCT, DFT or DWT. Several digital watermarking algorithms using wavelet transform are [...]
