Talk Abstract
Protection, manipulation and storage of digital audio, image and video

Ahmed H. Tewfik, University. of Minnesota

Audio, image and video data is increasingly available in digital format. This digital representation facilitates the reproduction, manipulation and transfer of the data. In particular, users can easily search and edit the data. However, it also facilitates theft and unauthorized use of the data. In this talk, I will discuss novel techniques for protecting and authentifying audio, image and video data. I will also describe novel approaches to data encoding that support retrieval by content and flexible playback over different channels and monitors.
