Project Description

This is "The Multimedia Signal Processing and Security Lab", short WaveLab, website. We are a research group at the Computer Sciences Department of the University of Salzburg headed by Andreas Uhl. The short name "WaveLab" already indicates that wavelets are among our favorite tools - we have 15 years of experience in this area. Our research is focused on Multimedia Security including Watermarking, Image and Video Compression, Medical Image Classification, and Biometrics.
   

Sample Data Compression and Encryption in Biometric Systems (BioComp)

 

Project Description:

BioComp (FWF TRP project L554) is a project on how to store and handle sample data in biometric systems where these data have been acquired in the form of visual data (e.g. fingerprints, iris and retina scans, face recognition, .....). Specific emphasis is given to efficient lossy compression techniques based on JPEG and JPEG2000 with low impact on recognition performance and to lightweight encryption schemes allowing for search in encrypted biometric datasets in order to protect the privacy of the enrolled users.
