Table of Content



Main research topics in the field of multimedia and security are:

  • Digital Audio Watermarking
  • Evaluation of Digital Audio Watermarking Schemes
  • Design and Implementation of StirMark for Audio (SMBA)
  • Security Evaluation of Computer Systems, Computer Networks and Digital Media
  • Mechanisms to Providing Secure Internet Communication, Services, etc.

The follow Links are:

  • StirMark for Audio a collection of audio signal modifications (attacks against digital robust audio watermarks) to evaluate and/or benchmark digital robust audio watermarks
  • Audio WET - an online service to evaluate and benchmark digital audio watermarking schemes interactive or in batch mode (depends on the complexity). To get access to this system, you must be registered!
  • Courses our courses for the students in Magdeburg
