PRIVIDEMA project (Privacy-Preserving Identity Management for Digital Wallets and Secure Data Sharing and Processing for Cyber Threat Intelligence Data) advances the state of the art in cryptographic and Privacy-Enhancing Technologies (PETs) to enable secure, interoperable, and trustworthy data exchange across sectors, with a focus on the domains of Cyber Threat Intelligence and Digital Identity Management. This paper presents two representative real-world use cases: (1) privacy-preserving digital identity management based on the European Digital Identity (EUDI) Wallet, and (2) privacy-preserving Cyber Threat Intelligence (CTI) sharing for Software Bill of Materials (SBOMs) and vulnerability datasets. Both use cases showcase how advanced PETs, including Fully Homomorphic Encryption (FHE), Federated Learning (FL), and Differential Privacy (DP), can be composed to protect sensitive data throughout its lifecycle while maintaining analytical and operational utility. Together, these use cases chart a practical course toward more scalable, standards-compliant, and privacy-preserving data ecosystems that align with Europe’s vision for secure and trustworthy digital services.
