      French academic and industrial research in cybersecurity is at the forefront of the international scene. While France cannot claim to have sovereignty over cybersecurity technologies, it undeniably possesses a wealth of skills, as French expertise covers all areas of cybersecurity.

      Research in cryptography illustrates French excellence, but it should not overshadow other domains where French influence is just as remarkable, including formal methods for security, protection of privacy, security of systems, software and networks, security of hardware systems and multimedia data security, according to the classification proposed by the CNRS Computer Security Research Network (GdR).

      The security of multimedia data is covered in this book. The evolution of our society from the written word to sound and image, with the notable arrival of the mobile phone and the democratization of the Internet has brought about new security needs. These are only the beginning of the transformation of our society, and the recent deployment of videoconferencing shows that research into the security of multimedia data is constantly confronted with new scientific challenges.

The complexity of the subject and its multidisciplinary dimension, which primarily combines signal processing and cryptography, are perfectly illustrated by the variety of subjects detailed throughout this book. The chapters thus reveal the scientific obstacles to be dealt with by the community, by anchoring them in real scenarios, such as the fraudulent copying of films, the deception of artificial intelligence or the spreading of doctored images on social media.

      This book, made up of two volumes, is thus promised to become a reference in the field of multimedia data security, an introduction that is both exhaustive and in-depth that students, engineers and researchers will be able to appreciate through more than 600 pages enriched with numerous references. Everyone can indulge in their favorite kind of reading, whether linear or random.

      Finally, I would like to thank all of the authors for their commitment to supporting the scientific community, and I would particularly like to thank William Puech for editing this edition of the book. William, alongside Patrick Bas and then Caroline Fontaine, is responsible for the theme of multimedia data security within the Computer Security GdR, thus allowing the entire cybersecurity community to better understand this fascinating subject.

      Happy reading!
