CS1.01 - Digital Watermarking and Authentication by Prof A Ho
The tremendous growth of digital multimedia content in the past few years has led to the growing concern and requirement for copyright protection for proof of ownership and content authentication. In this talk I will give an overview on digital watermarking and authentication of images and highlight the differences between robust, fragile and semi-fragile watermarking for law enforcement applications such as crime scene analysis and traffic enforcement. Another research area which is gaining momentum is binary image watermarking and some current work will also be presented.
