Introduction to digital watermarking

Watermarking allows owners or providers to hide an invisible and robust message inside a digital Multimedia document, mainly for security pur- poses such as owner or content authentication. There exists a complex trade-o(R) between the di(R)erent parameters: capacity, visibility and robust- ness. This lecture will give an introduction to digital watermarking in im- age and video, will present basic existing algorithms (ie state-of-the-art), and possible applications of watermarking technologies. It will also cover the general problem of robustness and evaluation.
