Since the 1st of february 2010, I am back to Inria Rennes. My adventures in Technicolor (formerly Thomson) are now over.

Profile
I received the DEA degree (M.Sc.) in digital communication in 1998 and the Ph.D degree in signal and image processing in 2002, both from the Ecole Nationale Superieure des Telecommunications, Paris, France.
From 1998 to 2001, I was a research engineer in the Security Lab of THOMSON multimedia, Rennes, France, working on digital watermarking in the framework of copy protection. I continued working in this field as a postdoctoral researcher at the TELE Lab of the Universite Catholique de Louvain, Louvain-la Neuve, Belgium. I am now a researcher with the INRIA Institute, working within the TEMICS project.
Best Paper Award IWDW 2004: ``Watermarking Attack: Security of WSS Techniques'', F. Cayre, C. Fontaine and T. Furon, Proc. IWDW, Seoul, South Corea, October 2004.
Brittany best young researcher award received in January 2006.
IH07 co-organizer with Patrick Bas, Francois Cayre and Gwenael Doerr.
BOWS-2 international challenge co-organizer with Patrick Bas.
I am associate editor for EURASIP Journal on Information Security.
I am involved or used to be involved in the Technical Program Committee of the following conferences: SPIE Security, Steganography and Watermarking of multimedia contents, ACM Multimedia and Security, Information Hiding, IDWD Int. Work. on Digital Watermarking, EUSIPCO European Signal Processing Conference.
Research Activities
Since my PH.D thesis, I am mainly working on digital watermarking and its application to copy protection. This includes:
Legal Aspects of copy protection
I think it is important, being a watermarking designer, to have a very good knowledge of the application one is targeting. I had the chance to meet Thierry Maillard, who is a researcher in the legal aspects of copyright. Whereas I had fuzzy ideas about such background, Thierry was willing to meet engineering people to improve his understanding of the technical means used in copy protection. This meeting resulted in an article published in Computer Law and Security Report. Moreover, we found this collaboration extremely interesting so that we (with Pierre Duhamel of LSS and Patrick Bas from LIS) submit a project to the CNRS to carry on this association of 'technicians' and 'lawyers'.

Design of copy protection systems
Once understood the issues of copy protection, I have created with my former colleagues of THOMSON multimedia two different system architectures. This is an extremely important process. Neither watermarking nor cryptography can alone be a solution to the copy protection problem. The designer has to mix them to build the system. This especially means to define the role of the watermarking in the global architecture.
The first try was a DVD copy protection system called DVD-COPS. It has been presented to the CPTWG, but it was quickly abandoned for the second project. SmartRight is a much more efficient system for copy protection in home networks. We have the opportunity to make an account of SmartRight in an article accepted to the Special Issue of the IEEE Signal Processing Magazine.

Security of watermarking
Once the architecture is built, the designer has to understand the potential threats for the watermarking primitives in this application. It means that there exists a dishonest user, an opponent, an adversary who will try to hack the system. This raises the concept of the security of watermarking.
My first fuzzy attempt to define security of watermarking was in my Ph.D. dissertation. I had the chance to improve this little theory for a CERTIMARK deliverable.
- T. Furon and others, Security Analysis, European Project IST-1999-10987 CERTIMARK, Deliverable D.5.5.
Moreover, F. Bartolini and M. Barni proposed me to co-chair a special session on watermarking session at EUSIPCO 2002. We were very glad to receive top quality submissions. They had the great idea to make an overview of these contributions.
- M. Barni, F. Bartolini and T. Furon, A general framework for robust watermarking security, invited paper to the Special Issue on Watermarking of EURASIP Signal Processing.
New watermarking methods
In the last step of the process, the designer selects a watermarking technique fulfilling the requirements and especially having a high security level against the potential threats. Not really happy with the existing techniques, I have invented two original methods. The first one is known as asymmetric watermarking, but it is more a randomized watermarking embedding.
- T. Furon and P. Duhamel, An asymmetric watermarking method, Special Issue on Signal Proecessing for Data Hiding in Digital Media and Secure Content Delivery, IEEE Trans. on Signal Processing, vol. 51, n. 4, April 2003.
The other one is named JANIS, Just Another N-order side-Informed watermarking System. I invented it at the end of my Ph.D and I improved it with G. Silvestre and N. Hurley from the Computer Science of UCD. This collaboration was possible thanks to the ULYSSES program.

Steganography
Steganography has nothing to do with copy protection. But, deeply interested by the works of J. Eggers, I was wondering whether SCS is perfectly suited for the steganography application. Pierre Guillon helped me a lot. Indeed, we invented a public-key stego-tool for audio content. Due to september 11th, I quit this field. So that, my first and last paper in steganography is:
