Current Research

The current multi-media research activities of the SIP group focus on four main broad areas:

• Processing
• Classification and Mining
• Communication
• Security & Privacy

Each of these research areas consist of several specific subjects for which the SIP group proposes novel solutions.

Overview and History

The SIP group has a long record of research in stochastic image modeling and processing, multimedia security and information-theoretic methods, published in over 200 journal articles, patents, conference papers, reports. In particular, the group has contributed to state-of-the-art methods in robust watermarking, multimedia authentication, robust perceptual hashing, low-complexity multi-class classification, stochastic modeling of images with applications to image restoration, denoising, compression and digital data-hiding for copyright protection, authentication and secure communications, multi-terminal communications and distributed coding. Several algorithms developed by the SIP group are top-ranking techniques according to international benchmarks.

In April 2003, Prof. Voloshynovskiy was awarded an SNF Professor Boursier grant (2003-2007) “Blind detection of hidden data” for the investigation of information-theoretic fundamentals of multimedia security based on digital data-hiding. Also in 2003, the SIP group created a second spin-off company: Anteleon Imaging Sarl.

In 2006, the group was granted the FNRS project “Information-theoretic document authentication and self-recovery based on digital datahiding” and “Secure unclonable identification/authentication codes based on natural randomness” in 2007. The group also participated to two EU Networks-of-Excellence: ECRYPT, dedicated to information security; and SIMILAR, specialized in multimodal information-theoretic signal processing. Prof. Voloshynovskiy was a co-leader of ECRYPT's Watermarking Virtual Lab.
