Use Cases

The lead partner of Use case 1 is PPC which constitutes one of the largest power suppliers in Northeastern Europe, with ~10 million customers in Greece, North Macedonia, and Romania.

Two particularly data-intensive use cases are relevant to the RECITALS project:

1. The identity management of its employees and external collaborators. The company’s activities rely on hundreds of applications, ranging from SCADA and ERP systems to cloud-based analytics platforms as well as customer and employee management applications. As a result, thousands of in-house and third-party users require access to confidential or highly sensitive data, with their roles and permissions changing on a frequent basis.
2. The detection of energy defaulters. Oftentimes, PPC’s consumers eventually become part of its customer base due to Greek regulations, which force the largest energy producers to ensure that no household is left without energy supply. To get rid of their unredeemed debt, these individuals frequently alter their identifying information, such as changing their address upon relocating to new residences or simply switching the account to another member of their family.

The PPC’s customers database provides RECITALS all contextual information necessary for detecting energy defaulters through privacy-preserving record linkage. This task will be carried out by the homonymous module of RECITALS’ value-added services, based on the Cryptography and Anonymization Manager of RECITALS core. Moreover, based on two RECITALS core modules, the Identity Lifecycle Manager and the Distributed Ledger, as well as on two value-added services, the Self-sovereign Wallet and the LLM-based interface, a privacy-preserving, holistic platform will be developed for addressing the variety, volume and velocity challenges of the identity management in the context of PPC’s versatile business operations.

The lead partner of Use case 2 is ORANGE Romania which is the largest telecommunications provider of the countey, and part of the Orange Group,providing B2B and B2C services to more than 11 milion customers and operating a state-of-the-art 5G Mobile Network, with commercial coverage in 38 cities in Romania.

A specific threat to the telecom infrastructures is represented by the sheer volume and complexity of the networks in operation. 5G raises the stakes exponentially. In comparison to previous generations of networks, 5G is decentralized and in many places virtualized, creating numerous new potential access points where none existed before. These various access points will require more employees to keep these networks up and running.

RECITALS aims to deliver an enhanced digital identity solution, based on privacy-preserving identity and access management, to support the highly dynamic lifecycle of a DevOps / DevSecOps enabled environment. This will enable a secure operational environment with clearly assigned roles and access privileges to specific identities and will support mitigation actions against insider threats from privileged users with access to core infrastructure.

The lead partner of Use case 3 is the Hospital do Espírito Santo Évora which serves as the primary and largest healthcare facility in the Alentejo region, attending to a population of almost 500.000 individuals.

Regarding privacy-preserving technologies in healthcare, there is a growing emphasis on leveraging advanced cryptographic techniques, such as homomorphic encryption and secure multiparty computation, to ensure the confidentiality of sensitive patient information. These methods enable data analysis without the need to expose raw patient data, thereby striking a balance between the need for information sharing and individual privacy. Digital
identity management in healthcare has seen significant advancements through the adoption of federated identity systems, where a patient’s identity can be securely authenticated across different healthcare institutions.

This particular use case plays a critical role in the RECITALS project by generating synthetic data through a dedicated testbed that mirrors the operational environment of HES and associated healthcare assets. In this testbed, dynamic datasets including user, infrastructure, and control plane data are specifically tailored to the contextual scenario envisioned for the Use-Case. This controlled and realistic environment ensures that the project can rigorously test digital identity management innovations in the healthcare sector. This will allow the project to demonstrate and test digital identity management innovations in the healthcare sector. RECITALS’ Cryptography and Anonymization Manager will facilitate the sharing of research data through the European Health Data Space (EHDS) in a secure and privacypreserving way that facilitates medical research and the development of new therapies.
