The paper “SynDEc: A Synthetic Data Ecosystem” by Fabian Karst, Mahei Li and Jan Marco Leimeister presents a system called SynDEc, which was developed using generative AI to share data securely and effectively. Especially small and medium-sized banks, which often do not have enough data for AI applications such as fraud detection and risk management, can benefit from it. SynDEc was tested together with two banks and offers clear approaches for handling synthetic data, training methods and incentives. The results show that SynDEc works even with few participants and helps small banks in particular. The paper provides practical solutions for data protection-compliant data sharing and creates a basis for the use of such systems in the financial sector.
