Project Description

This is "The Multimedia Signal Processing and Security Lab", short WaveLab, website. We are a research group at the Artificial Intelligence and Human Interfaces (AIHI) Department of the University of Salzburg led by Andreas Uhl. Our research is focused on Visual Data Processing and associated security questions. Most of our work is currently concentrated on Biometrics, Media Forensics and Media Security, Medical Image and Video Analysis, and application oriented fundamental research in digital humanities, individualised aquaculture and sustainable wood industry.
   

Privacy-protected Video Surveillance on Scalable Bitstreams (PrivSurv)

 

Project Description:

PrivSurv (FFG Bridge project 832082) is a project on developing privacy-protection mechanisms for video surveillance. Specific focus is set on applying RoI-based encryption technique on a bitstream basis, i.e. selectively encrypting JPEG2000 and H.264/SVC. This project is conducted in cooperation with Commend International GmbH and the Salzburg University of Applied Sciences (School of ITS).
