An open-source platform for Resilient sECure digITAL identitieS

RECITALS aims to build an open-source platform that integrates into a common framework a wide variety of techniques and services for privacy-preserving data sharing and identity management.

The platform consists of three main modules:1) RECITALS core provides a series of fundamental components that can be used as building blocks for constructing more complex services.

These include: the distributed ledger, the identity lifecycle manager, the cryptography manager, the anonymization manager as well as the compliance manager for horizontal EU legislation.2) RECITALS value-added services combine multiple components from RECITALS core into end-to-end pipelines that address specific needs: a self-sovereign wallet, privacy-preserving record linkage, privacy-preserving federated learning, LLM-based user interface, domain-specific compliance manager, privacy-preserving data analytics and explAIner, which sheds light into the decisions taken by trained ML and DL models.3) Security Manager provides all necessary means for ensuring the resilience of the entire platform.

To this end, it covers all aspects of cyber-security, from the analysis of possible cyber-attacks to their automatic detection and mitigation.Special care is taken to equip each component with the state-of-the-art techniques of the corresponding task.

As a result, each component acts as a library comprising a wide variety of established methods and can be used independently of the platform, for example by being integrated into any other system that leverages Python's open-source ecosystem.Another goal is to tweak the methods implemented by each component so as to enhance their time efficiency and scalability.The performance of the RECITALS platform will be tested in three demanding industrial use cases, to evaluate and verify its capabilities, while demonstrating how it goes beyond the current state-of-the-art in each considered field.
