    I am Professor (full) within the Département Image et Traitement de l'Information (ITI) of IMT Atlantique and I conduct my research activities in the Laboratoire de Traitement de l'Information Médicale (LaTIM Inserm U1101)

    Research activities

    Since several years, I am working on the protection of medical multimedia data, in particular of images and databases, with approaches essentially based on watermarking, crypto-watermarking and the processing of encrypted data. All these security solutions are studied in the case of medical imaging, big health data and genetic, through various funded research projects.

    Among our main results, we discussed the relevance of watermarking in the medical field

    Here follows relevant publications on different research topics I am working on.
