    Privacy, Utility, Effort, Transparency and Fairness: Identifying and Swaying Trade-offs in Privacy Preserving Machine Learning through Hybrid Methods
    (INFORMATIK 2024, 2024) Eleks, Marian; Ihler Jakob; Rebstadt, Jonas; Kortum-Landwehr, Henrik; Thomas, Oliver
    As Artificial Intelligence (AI) permeates most economic sectors, the discipline Privacy Preserving Machine Learning (PPML) gains increasing importance as a way to ensure appropriate handling of sensitive data in the machine learning process. Although PPML-methods stand to provide privacy protection in AI use cases, each one comes with a trade-off. Practitioners applying PPML-methods increasingly request an overview of the types and impacts of these trade-offs. To aid this gap in knowledge, this article applies design science research to collect trade-off dimensions and method impacts in an extensive literature review. It then evaluates the specific trade-offs with a focus group of experts and finally constructs an overview over PPML-methods and method combinations’ impact. The final trade-off dimensions are privacy, utility, effort, transparency, and fairness. Seven PPML-methods and their combinations are evaluated according to their impact in these dimensions, resulting in a vast collection of design knowledge and identified research gaps.

    Sustainable ecosystems: Findings from the NaWerSys workshop series
    (INFORMATIK 2024, 2024) Schoormann, Thorsten; Kammler, Friedemann; Gembarski, Paul Christoph; Hagen, Simon; Brinker, Jonas; Bollenbach, Jessica; Jussen, Ilka; Keller, Robert; Kortum-Landwehr, Henrik; Möller, Frederik; Petrik, Dimitri; Schweihoff, Julia; Stachon, Maleen; Winkelmann, Stephanie
    Ecosystems have the promising potential to respond to economic but also environmental and social challenges, such as by enabling circular thinking, establishing fair supply chains, responsible collaborations, and ensuring resilience. In this report, we summarize findings from multiple data sources in the context of the NaWerSys workshop series which was held together with the INFORMATIK conference. The results are informed by experiences collected from full-day paper sessions in 2021, 2022, and 2023, and a world café-based discussion with 15 participants from different backgrounds, including sustainability, engineering, platform governance, product service systems, and artificial intelligence. We structured the results along with four main fields of action concerning the core, the value, the design, and the management of sustainable ecosystems. By jointly elaborating on the status quo and possible research directions, the findings aim to advance our understanding and boost the concept of sustainable ecosystems.
