Frederico Schardong is a 2024 Vittorio Bertocci Awardee.
DIAF supported his journey to the 43rd International Conference on Conceptual Modeling this year. We invite you to read more about his research and perspective below.
I am Frederico Schardong, an associate professor at the Federal Institute of Rio Grande do Sul in Brazil. Previously, I had the opportunity to attend Vittorio Bertocci’s talks at Identiverse 2022, which were truly inspiring. It is an honor to receive the Vittorio Bertocci Award, which generously financed my participation in the 43rd International Conference on Conceptual Modeling. Hosted at the Software Engineering Institute of Carnegie Mellon University in Pittsburgh, this world-leading academic conference was an incredible platform to share my research and connect with experts in the field.
This past July, I defended my PhD thesis, which delved into various areas of identity and access management, leading to some key contributions:
- Post-Quantum Cryptography in OAuth 2.0 and OpenID Connect: I proposed and demonstrated the integration of post-quantum cryptographic techniques into these widely used protocols to enhance their security against future quantum threats.
- Systematic Literature Review and Taxonomy of Self-Sovereign Identity: This work provided a comprehensive mapping of the self-sovereign identity landscape, helping to clarify definitions in a rapidly evolving field.
- Fiduciary Identity Model: I specified a new digital identity model that fosters user autonomy with fiduciary intermediaries, aiming to improve usability, trust and security in digital transactions.
- Role-Artifact-Function (RAF) Framework: A theoretical framework that offers a precise, ambiguity-free method for describing digital identity models and the systems or protocols that implement them, utilizing a simple notation based on set theory.
The RAF Framework became a paper titled “The Role-Artifact-Function Framework for Understanding Digital Identity Models” that was presented at the 43rd International Conference on Conceptual Modeling. Presenting the RAF Framework to an audience of conceptual modelists was a significant milestone. Despite the time constraints, I was pleased to see that the community received my presentation warmly. Holding the last presentation slot before the closing ceremony meant there was limited time for extended discussions immediately afterward. However, the 10-minute Q&A session was engaging, leading to valuable feedback. Fortunately, many attendees were staying an extra night, and we continued our conversations over dinner. This informal setting provided a good opportunity to delve deeper into discussions about conceptual modeling and digital identity and explore potential collaborations.
Connecting with world-leading researchers and practitioners was a rewarding experience. Engaging with peers from other areas of computer science broadened my perspectives and generated new ideas. The diversity of research presented at the conference underscored the dynamic nature of conceptual modeling and its impact across various domains.
Overall, attending the 43rd International Conference on Conceptual Modeling was an enriching experience. It not only allowed me to share my work but also expanded my professional network with brilliant individuals. I am grateful for the opportunity provided by the Vittorio Bertocci Award and look forward to future collaborations that will stem from this conference.
