A2
Workshop on security and privacy in HF for technology centers and companies: identification of synergies and transfer of knowledge.
This closed activity was integrated into the annual CIBER.gal event in Galicia. Specifically, the TRUFFLES project workshop was incorporated into the agenda of the IV Encontro CIBER.gal .
On November 6, during the afternoon session, a roundtable titled “Challenges in Security and Privacy in Federated Learning” was held, featuring three speakers representing the academic (Dr. Javier Parra from UPC), industrial (Carlos Fernández, Senior Consultant in Artificial Intelligence at Indra), and SME/public administration sectors (Jaime Loureiro from Gradiant).
A3
Workshop on security and privacy in HF for technology centers and companies: sharing results and advances.
Planned for 2025 as continuation of the activity 2. Currently in the planning phase; further details coming soon.
A4
Seminar about (D)FL and cybersecurity (researchers & students oriented).
Fernando Pérez was invited to deliver the tutorial titled “Privacy 101, with Trumpets and Truffles – An Introduction to Differential Privacy and Homomorphic Encryption, and Applications in Federated Learning” at the IEEE International Workshop on Information Forensics and Security, held in December 2024. The seminar was conducted in situ with around 15 attendees from academia and industry, and the session was also projected to a broader audience. The recording is available (registration required) at:

A5
Challenge/hacking in the privacy field (students oriented).
Scheduled for 2025 (June–September), we’ve advanced this activity so that the TRUFFLES challenge can be integrated into a joint CTF (Capture The Flag) event organized by atlanTTic and CITIC (the two ICT research centers of the University of Vigo and the University of A Coruña). This adjustment is intended to generate greater impact and engagement.
A6
Working sessions within international projects and organizations.
- A talk on federated learning and privacy, entitled: «Federated Learning: trade-off between utility and privacy», has been scheduled on February 2 at 12.00 CET within the framework of the Athena Talks, given online by Professor Rebeca P. Díaz Redondo. The Athena Talks are organized by the European Athena University, an alliance of 9 universities in 9 EU countries (being UVIGO one of them). The orientation of the talk is informative for students and researchers of these universities, although they are open to any public.
- Alberto Pedrouzo participated in the “AI4EOSC Webinar Series – 3rd Session: Introduction to Federated Learning”, delivering the talk “Understanding Threats in Federated Learning”. A White Paper titled “Security Guidelines for Implementing Homomorphic Encryption” has been prepared, submitted, and accepted.
- A working session on decentralized federated learning was conducted as part of the AHUMAIN project training.
- Project members participated in the IEEEComSoc – CCNC in Las Vegas (January 2025).
A7
Organization of a special session at an international research conference.
We are orgaizing the 12th ACM Workshop on Information Hiding and Multimedia Security (IH&MMSec’24). This workshop stands as a premier event in the domain of multimedia security, drawing researchers globally. Sponsored by the prestigious Association for Computing Machinery (ACM), the workshop centers around information-hiding themes such as steganography, steganalysis, digital watermarking, anonymity, hard-to-intercept communications, and covert channels. Additionally, it encompasses various multimedia security subjects, including multimedia authentication, multimedia forensics, biometrics, and privacy. Participants present cutting-edge research conducted in academic, industrial, and government institutions worldwide. Papers cover significant theoretical aspects of the field, as well as novel industrial and commercial applications of techniques and
algorithms developed in the area.
