A Lossless Watermarking Scheme for Halftone Image Authentication
Nowadays, halftone images appear routinely in books, magazines, printer outputs, and fax documents. It is desirable to embed data in halftone images for copyright protection and content authentication. This paper proposes a novel watermarking scheme for halftone image authentication, exploiting image hash as a fragile watermark. After pixel blocking and ordering, a lookup table is constructed a...
متن کاملHybrid Watermarking Scheme for Halftone Images
As digital halftone images are widely used in the printing of books, magazines, newspapers and computer printers, the ease with which perfect copies can be made, may lead to large-scale unauthorized copying. Watermarking has been considered for many copy prevention and copyright protection applications. The hybrid watermarking system is proposed for halftone images that the watermarks embedded ...
متن کاملA robust watermarking scheme using self-reference image
In this paper, a robust watermark scheme for copyright protection is proposed. By modifying the original image in transform domain and embedding a watermark in the difference values between the original image and its reference image, the proposed scheme overcomes the weak robustness problem of embedding a watermark in the spatial domain. Besides, the watermark extraction does not require the or...
متن کاملHalftone Image Watermarking based on Visual Cryptography
In this paper we have proposed digital watermarking scheme for halftone images based on visual cryptography scheme. The scheme does not embed the watermark directly on the halftone image instead watermark will be divided into the parts called as shares. The scheme not only protects the watermark but also provides an effective copyright protection scheme. At the time of watermark embedding verif...
متن کاملContent-independent embedding scheme for multi-modal medical image watermarking
BACKGROUND As the increasing adoption of information technology continues to offer better distant medical services, the distribution of, and remote access to digital medical images over public networks continues to grow significantly. Such use of medical images raises serious concerns for their continuous security protection, which digital watermarking has shown great potential to address. ME...
