摘要:Early works in digital watermarking appeared in mid-nineties. Since then watermarking became a very hot research topics with advances made at an extremely fast pace. After a decade watermarking had become a mature technology backed by a solid theoretical framework. In subsequent years watermarking started being used in many practical and diverse applications, however research declined, with fewer and increasingly less innovative papers being published, yet several interesting problems still needs to be addressed and solved. It is the goal of this talk to: i) briefly go through the history of watermarking, ii) summarize the status of watermarking technology, iii) present some new results obtained recently by the speaker, and iv) highlight directions for future research in the attempt to bring watermarking research to new life.
个人简介：
Prof. Barni received the Ph.D. degree in informatics and telecommunications from the University of Florence, Italy in 1995. He is currently an Associate Professor with the University of Siena, Italy. Prof. Barni is a fellow of the IEEE. He is appointed as a Distinguished Lecturer of the IEEE Signal Processing Society from 2012 to 2013. He was a recipient of the IEEE SIGNAL PROCESSING MAGAZINE Best Column Award in 2008, and the IEEE Geoscience and Remote Sensing Society Transactions Prize Paper Award in 2011. He was the founding Editor-in-Chief of the EURASIP Journal on Information Security. He currently serves as an Associate Editor of the IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY and the IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY. From 2010 to 2011, he was the Chairman of the IEEE Information Forensic and Security Technical Committee of the Signal Processing Society. He has been a member of the IEEE Multimedia Signal Processing Technical Committee and the Conference Board of the IEEE Signal Processing Society.
During the last decade, his activity has focused on digital image processing and information security, with a particular reference to the application of image processing techniques to copyright protection (digital watermarking) and multimedia forensics. Recently, he has been studying the possibility of processing signals that have been previously encrypted without decrypting them. He led several national and international research projects on these subjects. He has authored about 270 papers, and holds four patents in the field of digital watermarking and document protection. He has coauthored the book Watermarking Systems Engineering (Dekker, 2004). His papers on digital watermarking have significantly contributed to the development of such a theory in the last decade.
