主讲人介绍：

Gouenou Coatrieux received the Ph.D. degree in signal processing and telecommunication from the University of Rennes I, Rennes, France, in collaboration with the Institut Mines Telecom, Telecom Paris-Tech, Paris, France, in 2002. His Ph.D. focused on watermarking in medical imaging.

He is currently an Full Professor in the Information and Image Processing Department, Institut Mines-Telecom, Telecom Bretagne, Brest, France, and his research is conducted in the Laboratoire de Traitement de l’Information Médicale, Unité INSERM U1101, Brest. His primary research interests include medical information system security, watermarking (images and database), digital content forensics, secure processing of outsourced data.

He is the head of the Joint Laboratory on Security and Processing of Externalized Medical Image Data. Pr. Coatrieux is actually associate editor of the IEEE Journal of Biomedical and Health Informatics and of the Elsevier journal. He has been associate editor of the Elsevier journals Digital Signal Processing. He is also member of the IFMBE “Global Citizen Safety and Security Working Group”, of the European Federation for Medical Informatics (EFMI) "Security, Safety and Ethics (SSE) Working Group", and has contributed to the Technical Committee of “Information Technology for Health (IT4H)” of the IEEE Engineering in Medicine and Biology Society.

内容介绍：

Nowadays, the security of information systems is based on the definition of a security policy the deployment of which results in the parameterization of security components (user authentication, access control, firewall, encryption and so on) in order to answer security objectives (integrity, confidentiality, availability …). If medical information systems are also concerned they however have their own specificities. As example, data integrity is of major concern and is imposed by the citizen. In such a framework, watermarking completes existing measures for protecting medical data advantageously, especially when it is combined with encryption. Its purpose is the insertion of a message, also called content or watermark, into a host multimedia document (text, sound, image or video). Depending on the relationship between the host and the content, watermarking can serve different security services within a medical information system. But at the same time, the deployment of such a solution is not free of constraints; preserving the signal quality for the diagnosis is mandatory. This talk will expose the complementary role of watermarking in healthcare, its applications and some watermarking modulations in application to images and databases which aim at preserving at best the image diagnosis value.
