From the reviews of the first edition: "This book encompasses results of research investigation and technologies that can be used to secure, protect, verify, and authenticate object and information from theft, counterfeiting, and manipulation ... . This book is unique because it has diverse contributions from the field of optics ... . It has compiled recent critical breakthroughs from academic and industrial research of the leaders in the field. This work is a perfect survey of the fast developing field and should not be missed in any library." (Jorg Stettler, Optik, Vol. 117, 2006)
