Statistical Multimedia Security and Forensics

There is an increasing interest in forensic and security technologies for multimedia due to the predominance of audiovisual contents in Internet traffic, and a growing concern for security, privacy, and information integrity. This course covers
several such technologies building on a common basis: statistics, in particular, estimation, detection and coding theories. After an introduction to these fundamentals, the course will describe how they can be applied to specific multimedia technologies, including watermarking and data hiding, steganography, robust hashing/media fingerprinting, forensic tampering analysis, and forensic device identification. We will also cover the emerging topics of intellectual protection of deep neural networks and privacy protection of federated learning, again building on the same statistical grounds.
The course will consist of lectures and hands-on sessions.
