Informatikkolloquium: Designing End-to-End Privacy-Friendly and Deployable Systems

Konrad-Zuse-Hörsaal (Raum B-201), Vogt-Kölln-Straße 30

Dr. Wouter Lueks, CISPA

Digital technology creates risks to people's privacy in ways that did not exist before. I design end-to-end private systems to mitigate these real-world privacy risks. In this talk I will discuss my designs for two applications. These applications highlight key aspects of my work: I analyse security, privacy, and deployment requirements; and address these requirements by designing new cryptographic primitives and system architectures.

In the first part of this talk, I will present DatashareNetwork, a document search system for investigative journalists that enables them to locate relevant documents for their investigations. DatashareNetwork combines a novel multi-set private set intersection primitive with anonymous communication and authentication systems to create a decentralised and privacy-friendly document search system. In the second part of this talk, I will give an overview of my recent work in designing privacy friendly systems for humanitarian aid distribution. In collaboration with the International Committee for the Red Cross (ICRC) we designed systems for the registration and distribution of humanitarian aid that meets the requirements of the ICRC, while providing strong privacy protection for humanitarian aid distribution.

Wouter Lueks is a tenure-track faculty member at the CISPA Helmholtz Center for Information Security in Saarbrücken, Germany. Before that he was a postdoctoral researcher at EPFL in Lausanne, Switzerland where he worked with Prof. Carmela Troncoso. He is interested in solving real-world problems by designing end-to-end privacy-friendly systems. To do so he combines privacy, applied cryptography, and systems research. His work has real-world impact. For instance, his designs for privacy-friendly contact tracing have been deployed in millions of phones around the world, and his secure document search system is being deployed by a large organization for investigative journalists.

Public Lecture Series: Taming the Machines. Frontier AI Regulation: from Trustworthiness to Sustainability

UHH, Main Building, West Wing, Edmund-Siemers-Allee 1, Room 221

Taming the Machines — Horizons of Artificial Intelligence. The Ethics in Information Technology Public Lecture Series

This summer‘s „Taming the Machine“ lecture series sheds light on the ethical, political, legal, and societal dimensions of Artificial Intelligence (AI).
This lecture series brings together perspectives from ethics, politics, law, geography, and media studies to assess the potential for preserving and developing human values in the design, dissemination, and application of AI technologies. How does AI challenge our most fundamental social, political, and economic institutions? How can we bolster (or even improve) them in times of technological disruption? What regulations are needed to render AI environments fairer and more transparent? What needs to be done to make them more sustainable? In what sense could (and even should) we hold AI accountable?
To explore these and other related questions, this public lecture series invites distinguished international researchers to present and discuss their work. To get the latest updates and details how to attend the lectures, please visit

Current AI regulation in the EU and globally focus on trustworthiness and accountability, as seen in the AI Act and AI Liability instruments. Yet, they overlook a critical aspect: environmental sustainability. This talk addresses this gap by examining the ICT sector's significant environmental impact. AI technologies, particularly generative models like GPT-4, contribute substantially to global greenhouse gas emissions and water consumption.
The talk assesses how existing and proposed regulations, including EU environmental laws and the GDPR, can be adapted to prioritize sustainability. It advocates for a comprehensive approach to sustainable AI regulation, beyond mere transparency mechanisms for disclosing AI systems' environmental footprint, as proposed in the EU AI Act. The regulatory toolkit must include co-regulation, sustainability-by-design principles, data usage restrictions, and consumption limits, potentially integrating AI into the EU Emissions Trading Scheme. This multidimensional strategy offers a blueprint that can be adapted to other high-emission technologies and infrastructures, such as block chain, the meta-verse, or data centers. Arguably, it is crucial for tackling the twin key transformations of our society: digitization and climate change mitigation.
