It is becoming necessary, urgent, not to say vital, to secure this multimedia data during its transmission or archiving, but also during its visualization. In fact, with everything digital, it is becoming increasingly easy to copy this multimedia data, to view it without rights, to appropriate it, but also to counterfeit it.

Over the last 30 years, we have observed an expansive development around multimedia security, both internationally and in France. In fact, at the French level, there are dozens of research teams in laboratories, but also a large number of industrials, who are focusing their activities on these aspects. This activity can also be found in several GdR (research groups) of the CNRS, but in particular the GdR ISIS (information, signal, image and vision) and the GdR computer security.

Multimedia security is a relatively new theme, as evidenced by the publication dates of the articles referenced in the various chapters ...
