Digital Sovereignty: Deciding how to share

Episodencover: Folge 8 zum Thema Digitale Souveränität: Entscheiden, wie man teilt

There is no shortage of reports highlighting Germany’s and Europe’s serious technological dependencies: social networks, cloud services, artificial intelligence – they are lagging in many areas and in danger of being left behind altogether. The lack of digital sovereignty did not arise suddenly, but in times of intensifying geopolitical conflicts, it now appears threatening. Europe is missing economic opportunities and has no influence on the design of the technologies. The technological dependencies also affect data sharing: citizens and companies in Europe are exposed to the risk of critical data being leaked. But what exactly are these dependencies and how do they affect everyday data sharing? What are the prospects for developing greater digital sovereignty?

Episode 8: Digital Sovereignty: Deciding how to share

Digital sovereignty is one of the key concepts in the debate on digital policy – and is often used to highlight the lack of sovereignty in the digital sphere. This lack did not arise suddenly, but in times of intensifying geopolitical conflicts, these dependencies now appear threatening. What are these dependencies and how do they affect data sharing? And what are the prospects for developing greater digital sovereignty? That’s what episode 8 of ShareCast is all about. | listen now

Episode 7: A dream of open knowledge: data sharing in science

The seventh episode deals with an entire area of modern society: science. We explore the significance of sharing digital data for scientific work and discuss the opportunities and challenges currently being debated in this field. | listen now

Episode 6: Open source software: shared or closed?

Open source software is software under free licences that grants its users four freedoms: to run the software for any purpose, to examine how it works and thus also its source code, to adapt it to their own needs, and to redistribute the software, even in modified versions. This distinguishes it from software that the open source movement refers to as ‘proprietary’ or ‘closed source software,’ which does not offer these ‘fundamental freedoms.’ But how exactly is collaboration and sharing carried out here? What interests determine the open source world, and what conflicts exist? | listen now

Episode 5: Data, Forests, and Timber

The fifth episode of ShareCast focuses on the data generated in the forest and forestry and timber industries. How is this data created? What is it used for? Who has an interest in it? Why is this data not shared? What stands in the way of this? What potential could be realized if this were to succeed? And how could the obstacles to data sharing in forestry and the timber industry be removed? | listen now

Episode 4: Connected Cars: Improvement or Data Hogs?

Having your own car was once a great promise of freedom. Getting into the car and being able to drive wherever we wanted. And keep to yourself: With your partner or family. This image of the car is still there – and yet another one is slowly taking over. Cars are now highly networked, high-performance machines that are constantly filming, recording and measuring. The manufacturer is virtually at the wheel. | listen now

Episode 3: Smart City: Data Overload?

In the third episode of ShareCast, we talk about the interplay between data and urban development. We take a look at what is associated with the term smart city and discuss the potential and challenges that smart city concepts entail. | listen now

Episode 2: Health Data: Just for Me or Donation?

On the one hand, the sharing of data is intended to provide a major boost to innovation in medical research and help improve healthcare. On the other hand, health data is extremely sensitive data, i.e. data with a clear personal reference that can cause great harm in the wrong hands. This difficult balancing act is illustrated very clearly when it comes to so-called rare diseases. | listen now

Episode 1: Data: Nothing (easier) to share?

We shed light on some of the things behind buzzwords such as sharing economy, data silo, platform economy and open science. And we examine the heterogeneous understandings that are associated with sharing: voluntarily giving away data for a specific purpose, sharing data with a counterpart, passing on data in a group or making data openly available to everyone – these are very different things. | listen now

A dream of open knowledge: data sharing in science

Episodencover
Episodencover

The seventh episode deals with an entire area of modern society: science. We explore the significance of sharing digital data for scientific work and discuss the opportunities and challenges currently being debated in this field. Data sharing is a fundamental prerequisite for science, because in order to verify the validity of theories, models, and measurements, the relevant data must be made available to the scientific community. The digital transformation has given rise to various technologies that enable new forms of data generation, processing, and linking, and scientific methods themselves have also evolved. The concept of open science has become prominent in this context. It embodies something of a dream for humanity: the idea of open, freely circulating knowledge that all people can use to improve their livelihoods or satisfy their thirst for knowledge. In order for science to help shape social development and accompany economic change in an innovative way in a digitalized world, openness is needed, but so are sensible regulations and reliable infrastructures.

When we go for walks in the forest, we try to leave our digitized everyday lives behind us but work in forestry has long since been digitized. Data is collected by sensor networks, drones, satellites, and, above all, large forestry machines such as harvesters. This data is of great interest for increasing the efficiency of the timber industry and optimizing planning, for example in sawmills, but above all for protecting the forest and adapting it to the intensifying climate change. However, there are numerous obstacles to sharing this data. We talked to our guests about these obstacles and the possibilities for overcoming them. Last but not least, we also discussed the data trustee DTMForst, which aims to alleviate technical and legal uncertainties and give data providers opportunities for control.

Connected Cars: Improvement or Data Hogs?

Episodencover

Your own car – that used to be a great promise of freedom. Climb into your car and go wherever you like, on your own terms. And do it all in private: with your partner or your family. This image of the car still exists – yet slowly, a new one is taking its place. Cars have now become highly connected, high-performance machines that constantly record, measure, and monitor their surroundings. In a way, the manufacturer is virtually in the driver’s seat, through hundreds of sensors, microphones, cameras, and also devices connected to the car, such as your smartphone and the vehicle’s app. And in the future, cars are expected to become even more independent – for example, capable of driving fully “autonomously.” This shift from mechanically driven to software-driven vehicles requires one thing above all: data. That’s why, in the fourth episode of ShareCast, we discuss the present and future of connected cars, their insatiable appetite for data, and the latest approaches to data management currently being explored in the automotive industry.

Smart City: Data Overload?

Episodencover des Sharecast. Folge 3, Smart City: Daten im Überfluss

In the third episode of ShareCast, we talk about the interplay between data and urban development. We take a look at what the term “smart city” means and discuss the potential and challenges that smart city concepts bring with them.


City data is of interest and value to citizens in terms of sovereignty, but also to administrations and in terms of economic aspects. The connection between data and city management therefore holds great potential – including in the areas of ecology, social coexistence, and participation. Projects such as Darmstadt’s data platform, the “Darmstadt im Herzen” app, and “Gieß den Kiez” are examples of how citizens can gain more knowledge about their city or how city data can be used to help make their city smarter. At the same time, however, the city is not a “data lucky bag” from which all stakeholders can derive unlimited benefits. Rather, it is important to search specifically for viable ideas, consider opportunities for participation, and design new offerings carefully, in a user-friendly and secure manner. The collection, storage, and communication of city data also involves a great deal of effort, because processes must be organized, secured, and continuously developed. This requires appropriate security measures and IT skills—many requirements that are not always easy to meet and which we will also adress in this episode.

UNESCO has declared 2025 the “International Year of Quantum Science and Technology.” Quantum physics has existed for around one hundred years, and since then, it has provided the theoretical foundation for numerous technologies. Quantum computing is regarded as one of the most important future fields of digital technology and is expected to bring abstract scientific concepts into application in a spectacular way. This requires a complex network of funding programs, international collaborations, and interdisciplinary lighthouse projects, as well as the creative curiosity of scientists. However, competitive effects and geopolitical strategies are also becoming increasingly important.

In recent months, significant advances in the field have ushered in a new chapter. Today, societies should expect quantum computing to become available soon. This also means that, in the near future, traditional methods of encrypting digital communication will become obsolete due to the capabilities of quantum computing. Additionally, optimization problems of all kinds will be solvable at high speeds, including traffic control, weather prediction, combat operations, and surveillance measures. What can we expect from quantum computing in the coming decades? How should we approach the social classification of these new realities?

Frank Wilhelm-Mauch, a professor of theoretical physics at Saarland University, is coordinating the construction of a quantum computer for Europe at Forschungszentrum Jülich as part of the European flagship project, OpenSuperQPlus. In this episode of Digitalgespräch, the expert in the fundamentals and application of quantum computing, discusses the significance of quantum computing in 2025. He also describes the impact of important technical and societal processes on research conditions and how industry, politics, and science interact with each other. Finally, he talks about the applications we can soon expect from quantum computers. With hosts Marlene Görger and Petra Gehring, Wilhelm-Mauch will discuss the challenges posed by the field’s interdisciplinary nature, the interaction between quantum computing and artificial intelligence, the application of smart risk management in the face of this powerful technology – and the prevalence of the question of responsible design in the specialist community today.

Health Data: Just for Me or Donation?

Cover der ShareCast-Podcastfolge 2 Gesundheitsdaten: Nur für mich oder Spende?

In the second episode, we take a look at a specific domain where data sharing is both necessary and difficult, and where new forms of data sharing are being discussed and tested. We focus on health data and data use in medicine. We talk about the opportunities and challenges associated with this. On the one hand, data sharing is expected to drive major innovations in medical research and contribute to improving healthcare. On the other hand, health data is extremely sensitive, meaning it is clearly linked to individuals and can cause great harm if it falls into the wrong hands. This difficult balancing act is particularly evident when it comes to rare diseases. Various projects are attempting to master this challenge, and we spoke to two of them. The Independent Trust Agency in Medicine at TU Dresden aims to make health data collected at the university hospital accessible for medical research while protecting the legitimate interests of those providing the data. The TrustNShare project has developed a data trustee in the form of an app. The aim is to bring together data providers who want to share their health data – in some cases for a fee – and data users who want to conduct research with this data.

ShareCast Episode 2: Health Data, 22 July 2025

Guests


Prof. Dr. Thomas O. F. Wagner is an internist, pulmonologist and professor at the University Hospital of the Goethe Universität Frankfurt. There he heads the Reference Center for Rare Diseases.


Philipp Heinrich is head and consultant of the Independent Trustee Office in the field of medicine at the Technische Universität Dresden.


Prof. Dr. Cord Spreckelsen is Professor of Medical Informatics at the Friedrich Schiller Universität Jena and was head of the TrustNShare project. He is currently also involved in the AVATAR project.

Episode 8: Digital Sovereignty: Deciding how to share

Digital sovereignty is one of the key concepts in the debate on digital policy – and is often used to highlight the lack of sovereignty in the digital sphere. This lack did not arise suddenly, but in times of intensifying geopolitical conflicts, these dependencies now appear threatening. What are these dependencies and how do they affect data sharing? And what are the prospects for developing greater digital sovereignty? That’s what episode 8 of ShareCast is all about. | listen now

Episode 7: A dream of open knowledge: data sharing in science

The seventh episode deals with an entire area of modern society: science. We explore the significance of sharing digital data for scientific work and discuss the opportunities and challenges currently being debated in this field. | listen now

Episode 6: Open source software: shared or closed?

Open source software is software under free licences that grants its users four freedoms: to run the software for any purpose, to examine how it works and thus also its source code, to adapt it to their own needs, and to redistribute the software, even in modified versions. This distinguishes it from software that the open source movement refers to as ‘proprietary’ or ‘closed source software,’ which does not offer these ‘fundamental freedoms.’ But how exactly is collaboration and sharing carried out here? What interests determine the open source world, and what conflicts exist? | listen now

Episode 5: Data, Forests, and Timber

The fifth episode of ShareCast focuses on the data generated in the forest and forestry and timber industries. How is this data created? What is it used for? Who has an interest in it? Why is this data not shared? What stands in the way of this? What potential could be realized if this were to succeed? And how could the obstacles to data sharing in forestry and the timber industry be removed? | listen now

Episode 4: Connected Cars: Improvement or Data Hogs?

Having your own car was once a great promise of freedom. Getting into the car and being able to drive wherever we wanted. And keep to yourself: With your partner or family. This image of the car is still there – and yet another one is slowly taking over. Cars are now highly networked, high-performance machines that are constantly filming, recording and measuring. The manufacturer is virtually at the wheel. | listen now

Episode 3: Smart City: Data Overload?

In the third episode of ShareCast, we talk about the interplay between data and urban development. We take a look at what is associated with the term smart city and discuss the potential and challenges that smart city concepts entail. | listen now

Episode 2: Health Data: Just for Me or Donation?

On the one hand, the sharing of data is intended to provide a major boost to innovation in medical research and help improve healthcare. On the other hand, health data is extremely sensitive data, i.e. data with a clear personal reference that can cause great harm in the wrong hands. This difficult balancing act is illustrated very clearly when it comes to so-called rare diseases. | listen now

Episode 1: Data: Nothing (easier) to share?

We shed light on some of the things behind buzzwords such as sharing economy, data silo, platform economy and open science. And we examine the heterogeneous understandings that are associated with sharing: voluntarily giving away data for a specific purpose, sharing data with a counterpart, passing on data in a group or making data openly available to everyone – these are very different things. | listen now

2.2. Small Money, big impact? – Digital Tipping

Episodencover Staffel 2 Folge 2
Episodencover Staffel 2 Folge 2

Tips are often treated as casually as they are given. What exactly constitutes a tip can’t even be clearly defined in legal terms, but rather resembles a kind of “moral agreement,” as historian Winfried Speitkamp puts it. In his small volume Der Rest ist für Sie! (“Keep the Change!”), he has produced one of the very few German academic publications on the history of tipping. Yet tipping is far from a trivial matter: 10 percent on every tip-worthy transaction – at a restaurant or in a taxi, at least in Germany; in the U.S., it’s well known that the standard is about double that, roughly 20 percent. From an economic perspective, this adds up to astonishing sums – more than 2 billion euros per year in German restaurants alone – which, however, are barely regulated in Germany and, above all, don’t have to be taxed.

In the digital context, the nature of these casual, almost hidden micro-payments has shifted. Will digital technologies accelerate tipping – or its decline? That’s the question we explore in the second episode of our series on microtransactions.

2.3. Small Money, big Impact? – Microtransactions in Gaming

Episodencover Staffel 2 Episode 3
Episodencover Staffel 2 Episode 3

Already in the 1970s, the success of microtransactions in gaming began with the so-called arcade video games: In public arcades, games like Donkey Kong or Pac-Man could be started by inserting a coin into a machine. Today, so-called free-to-play games – which dominate the market – are initially offered at no cost and financed through microtransactions that allow players to purchase progress, items, or characters within the game.

Parts of the gaming industry have developed particularly sophisticated strategies: Through very small payments – individually negligible – the threshold for making a transaction is reduced to a minimum. And once someone makes a purchase, they are likely to do so again –such is the intelligence (or manipulation) of data-driven algorithms in their search for the small pool of high-spending players. These are often minors and gradually fall deeper into dependence on the game. In industry jargon, they are referred to as whales, whom game developers aim to “catch.”

Moreover, microtransactions have also changed game design itself: if the goal is no longer to promote the game as a product worth buying, but rather to continuously monetize it from within, then the game will be designed in a way that frequently makes transactions seem necessary. A mechanism of manipulation?
