IEEE Signal Processing Chapter Presentation:

Digital Watermarking: an overview of the technology and applications

Abstract:
The internet has created an environment for the proliferation of digital data such as audio, image and video. This has led to the problem of copyright protection of content in digital form. Digital watermarking are signal processing techniques that are used to embed information, which are usually hidden and/or imperceptible, into digital data and can be used to assist in copyright protection, as well as other applications such as metadata insertion. This talk will provide an overview of watermarking technologies and applications. Issues involved in designing and using watermarking including robustness and attacks characterization will also be discussed. Some of the presenter?s research work in wavelet based watermarking will also be discussed.

Presenter(s):
David Tay received BEng (electrical engineering) and BSc (mathematics) degrees from the University of Melbourne and a PhD (signal processing) degree from Cambridge University. He was a research associate in Trinity College before joining the EEE school, NTU in June 1995 as a lecturer and later as an assistant professor.

He joined the Dept. of Electronic Engineering, LaTrobe University in July 1999 as a lecturer and in January 2002 was appointed to Senior Lecturer. He has taught undergraduate and postgraduate courses in multimedia signal processing, communication systems and digital television systems. He is also involved in collaborative work with Monash Medical Centre in cardiovascular research and Analog Devices Australia in Digital Signal Processing projects. His research interest is in the area of signal and image processing with special interest in the theory, design and applications of multirate filter banks and wavelets.
