Biomedical signal and information hiding has a long history. Written in an easy-to-read and comprehend, straightforward style, this book addresses to the need of improvements in data hiding algorithms or techniques within a biomedical signal to ensure authenticity and security of patients¿ information. The author has used embedding of watermark within biomedical signal as the optimization problem, which is solved using Particle Swarm Optimization and Genetic Algorithm based techniques. This book also offers MATLAB result sets, tables, flow charts and illustrations to exemplify the complicated concepts discussed in the text. This book is published in the hope that it will interest students and research workers in biomedical signals and watermarking.
