I am currently working as CNRS researcher in the Centre de Recherche en Informatique, Signal et Automatique de Lille (CRIStAL), Lille, France, working on multimedia security. My research focuses on multimedia data processing and protection in the encrypted domain, in particular on reversible data hiding in encrypted images, correction of noisy encrypted images, recompression of crypto-compressed images and forensics in the encrypted domain. I completed my PhD degree in computer science from the Université de Montpellier, France, in 2020, in the ICAR - Image & Interaction team of the LIRMM, Montpellier, France, under the supervision of William Puech.
Digital image security plays a significant role in all fields, especially in highly confidential areas like the military and medical worlds. With the development of cloud computing, the growth in information technology has led to serious security problems where confidentiality, authentication and integrity are constantly threatened, by illegal activities like hacking, copying or malicious use of information. The aim of encryption methods is to guarantee data privacy by fully or partially randomizing the content of original images. During the transmission or the archiving of encrypted images, it is often necessary to analyze or to process them without knowing the original content, or the secret key used during the encryption phase. Many applications exist, such as visual secret sharing (VSS), data hiding in encrypted images, research and indexing in encrypted databases or recompression of crypto-compressed images.
