Trusted Data Sharing enables the secure and controlled exchange of data between participants, supported by trust-establishing frameworks and mechanisms. In federated ecosystems, participants integrate their Data Meshes under a unified regulatory framework, such as agreed Security and Data Management Policies, to facilitate scalable collaboration and ensure compliance with governance standards, security measures, and interoperability requirements. When no pre-established frameworks exist, data spaces offer dynamic environments where participants negotiate sharing rules and usage rights case by case. These spaces rely on technologies like IDS Connectors, smart contracts, and metadata brokering to enforce policies and uphold data sovereignty. Both approaches prioritize interoperability, regulatory compliance, and trust, enabling secure collaboration across diverse ecosystems.
