For the press
If you are looking for a background expert or interviewee on privacy topics, everything you need is here. I regularly give interviews to radio, television, and print media, and I try to respond quickly.
What I am happy to comment on
- Face recognition and camera surveillance — what a system actually sees, the difference between recognition and identification, and where the boundaries are
- Anonymisation and de-anonymisation — when an anonymised dataset really protects, and when it can still be traced back to individuals. Why deleting names is not enough, and what this means in practice for health, mobility, or published public data
- Web tracking and fingerprinting — how users are recognised without cookies, even across browsers
- Risks and side effects of artificial intelligence — what a model knows about us, what it reveals, and what to watch out for in daily use
- Algorithmic decisions and responsibility — credit scoring, insurance, job search, law enforcement, healthcare: more and more areas rank people using opaque models. Who is responsible for erroneous or discriminatory decisions, and is it possible to appeal an algorithm's judgement at all
- AI promises, predictions, and reality — what an AI system can do today, and what is just being sold to us. Where the real limits of current technology are, how well-founded the announcements about AGI and breakthroughs within a few years are, and what to ask when such news arrives
- AI and the future of work — does AI automate tasks or entire jobs? What real data shows so far, who the winners and losers are, and how realistic the scenario of major changes within a few years is. What is worth teaching our children about this
If the topic is borderline, feel free to contact me anyway: if it is not my field, I will say so, and if I can, I will recommend someone more knowledgeable.
About me
Gábor György Gulyás has worked on the technical aspects of privacy since 2005, alternating between research and the market. He is the managing director of Vitarex Studio, where he leads the VeriDome project: a pseudonymised face recognition procedure and the video analysis system built on it. Between 2017 and 2022, he led the device fingerprinting research and development team at SEON, and previously worked as a researcher at the Budapest University of Technology and Economics and the French Inria research institute. He wrote his doctoral dissertation on de-anonymisation in 2015, and his scientific publications have received 542 citations so far. With his colleagues, he was the first to propose the concept of browser-independent device identification, and one of their studies was presented in the European Parliament.

The last two digits of the phone number are intentionally a puzzle — because of harvesting robots. Sorry for the extra second it takes.
Before deadline, I am most quickly reachable by phone.
