🎧 (German) Podcast Tip: Scammed by an AI voice?
If Elon Musk suddenly calls, it's likely a deepfake. Cloning voices with AI takes just seconds — and scammers are all over it. CISPA researcher Lea Schönherr explains how.

In 2023 I successfully defended my PhD thesis at Imperial. Two years later, it's great to be back to Imperial College London & the Royal Albert Hall for the graduation ceremony. It brought up so many memories and was a blast!

The 6th Interdisciplinary Summerschool on Privacy (ISP 2025) The official website of the ISP Summerschool. Find out more about dates, tutorials, talks, the programme, the venue, and travelling suggestions.

We're organizing the interdisciplinary summer school on privacy again. It focuses on implications of privatizing digital services in the public sector, and it's aimed at PhD students from social sciences, law, and computer science. We emphasize group work, in parallel to lectures:

The example given in the article is meant to illustrate what people think synthetic data can do (the claims made about synthetic data and hype around it) and not what it can actually do at the moment.

Nvidia Bets Big on Synthetic Data Nvidia has acquired synthetic data startup Gretel to bolster the AI training data used by the chip maker's customers and developers.

I had the pleasure to give an interview about synthetic data www.wired.com/story/nvidia... by @laurengoode.bsky.social for Wired.

I'd like to add a caveat: the promises of synthetic data to solve privacy and data scarcity issues are not yet backed up by scientific evidence.

A screenshot of the paper, with the following section highlighted: However, differential privacy has been shown to not fully mitigate the risk of re-identification. Stadler and colleagues have shown that under certain circumstances, neither the original implementation of PrivBayes nor PATEGAN (Private Aggregation of Teacher Ensembles Generative Adversarial Network) reliably prevents linkage attacks, leaving some samples vulnerable to membership inference attacks.

Reading synthetic data papers in healthcare journals is often infuriating as a privacy (ex-)researcher, but I stumbled across one that is really egregious. The authors cite Stadler et al. (the initial work on membership inference attacks on SDG), to (wrongly!) dismiss a SOTA notion of privacy,

AI Slop Is a Brute Force Attack on the Algorithms That Control Reality Generative AI spammers are brute forcing the internet, and it is working.

I totally agree: "as a society need to realize that a huge portion of what is being done with generative AI tools is for the type of thing I have described in this article, or for nonconsensual, AI-generated intimate imagery." Must read article: www.404media.co/ai-slop-is-a...

Bending the arc of AI towards the public interest By Abeba Birhane, 18/02/2025 Following the first in Bletchley Park in 2023 and the second in Seoul in 2024, the third AI Action Summit took place in February 2025 in Paris. In the context of previous ...

I was in Paris last week for the #AIActionSummit & was honoured to participate in the “AI in public interest” panel.

Looking forward to presenting my research on automated privacy evaluations of anonymisation techniques in the Cyber- & AI-Security track organised by Swisscom at @appliedmldays.bsky.social

This paper ieeexplore.ieee.org/abstract/doc..., published at ICAIC25, blatantly plagiarises a paper by myself and colleagues at the Turing,, claiming that they developed the sqlsynthgen package. Although the text has been rephrased, the contents are nearly identical.

Anonymization: The imperfect science of using data while preserving privacy Safe anonymization and sharing of personal data will be achieved by combining formal privacy methods with red-teaming.

Fantastic, very practical review, on the challenges in data and model anonymization.

Also highlights the enormous gap between what is theoretically possible and what used in practice (eg. N>5 rule)

For my first post on Bluesky, here is a recommended read for anyone interested in the science of re-identification. This is a paper that's elegant, deep, and solves a real problem. I still remember how my mind was blown away when I read it. Congratulations @rocher.lc @yvesalexandre.bsky.social
