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.
   

Biometric Sensor Forensics (BioSensors)

 

Project Description:

BioSensors (FWF project P26630) is a project on using media forensics to enhance biometric systems security. Image and video forensics have emerged to complement classical cryptographic techniques and active media security techniques, in application cases where these passive technologies can offer advantages to the more established methodologies. This projects aims to apply image forensic techniques in the context of fingerprint and iris biometric systems, by taking care of (1) the specific nature of biometric sensors and (2) the specific nature of biometric sample data. In particular, questions of biometric sensor authentication, biometric sample data integrity verification, and biometric sensor ageing will be covered. We will contribute to biometric system accuracy, reliability, and security with the results of this project.
