چکیده
0278-6648/03/$17.00 © 2003 IEEE 37 The recent growth of Internet usage and networked multimedia systems has necessitated the need for the protection of digital media. This is especially critical for the protection and enforcement of intellectual property rights. Copyright protection involves the authentication of object (text/image/video) ownership, and the identification of illegal copies of a (possibly forged/fake) object. Techniques are needed to prevent the copying, forgery and unauthorized distribution of images and video. In the absence of above, placing images or video sequences on a public network puts them at risk of theft and alteration. The need for watermarking emanates from the following: A designer has created an image and wants to make it available on the network. When unauthorized copies or forgeries of the image appear elsewhere on the network, the designer needs to prove his ownership of the image. One also needs to determine if and by how much the image has been changed from the original. This way the person can prove ownership by illustrating the difference between the forged image and the original.

متن کاملAn SVD-based watermarking scheme for protecting rightful ownership
Digital watermarking has been proposed as a solution to the problem of copyright protection of multimedia documents in networked environments. There are two important issues that watermarking algorithms need to address. Firstly, watermarking schemes are required to provide trustworthy evidence for protecting rightful ownership; Secondly, good watermarking schemes should satisfy the requirement ...
متن کاملRobust image watermarking based on generalized Radon transformations
This paper presents a novel watermarking scheme able to resist geometric attacks. The proposed method performs imperceptible watermarking of images in the spatial domain. To generate resistance to scaling and rotation attacks, two generalized Radon transformations of the image are introduced, while resistance to translation is accomplished through a localization of the watermarking method based...
