The IEEE International Workshop on Information Forensics and Security (WIFS) 2024 will be the 16th edition of the major annual event organized by the IEEE Information Forensics and Security Technical Committee (IFS-TC) of the IEEE Signal Processing Society (SPS). In recent years, research in the areas of information forensics and security has gained paramount importance in our increasingly digitalized world. As technology advances at an unprecedented pace, as testified by the amazing recent progresses in artificial intelligence, so do the methods employed by malicious actors to compromise and exploit sensitive information. Thus, conducting research aimed at understanding and countering such threats, as well as at developing tools and practices that could safeguard individuals, organizations, and even nations from cyberattacks, data breaches, and online fraud, plays a vital role in modern society, in order to preserve trust and confidence in our digital infrastructure. Within this context, the major goal of WIFS is to bring together researchers working in the different areas of information forensics and security to discuss challenges, exchange ideas, and share state-of-the-art results and technical expertise, with the aim of building a community capable of providing adequate tools and solutions to face the challenges of tomorrow. WIFS 2024 will be held in Rome, Italy, from December 2 to December 5, hosted by Roma Tre University, and it will see the participation of researchers from all over the world, who will allow to have a high-level technical program, also thanks to the expertise of the program committee involved, and who will have the opportunity to exploit an interesting social program taking advantage of the charm of the Eternal City.
