Advanced Techniques in Multimedia Watermarking: Image, Video by Ali Mohammad Al-Haj

By Ali Mohammad Al-Haj

Lately, the large development of electronic expertise has elevated the convenience with which electronic multimedia records are kept, transmitted, and reproduced. simply because conventional copyright equipment are wrong for constructing possession, electronic watermarking is taken into account the most effective recommendations to avoid unlawful and malicious copying and distribution of electronic media. complicated strategies in Multimedia Watermarking: photograph, Video and Audio functions introduces readers to cutting-edge learn in multimedia watermarking. masking new developments in electronic photograph watermarking and methods for implementation and optimization throughout diversified media, this booklet is a helpful better half for pros and researchers operating in parts resembling record watermarking, multimedia fingerprinting, info hiding, secured e-commerce, copyright defense, and implementation of real-time multimedia watermarking.

Steganographic systems that modify least-significant bits of the carrier image are often susceptible to visual attacks (Westfeld and Pfitzmann, 1999). Visual attacks mean that one can see steganographic messages on the low bit planes of an image because they overwrite visual structures, which exists to some degree in all the image’s bit layers; this usually happens in BMP and GIF images. This is not true for our Fourier magnitude steganography method. The data hiding takes place in the frequency domain, and only the magnitude spectrum of the chrominance-a channel of the carrier image is modified, leaving the luminance channel as well as the other chrominance-b channel unaltered.
