This user manual explains the features of the two tools implemented in Task 9.2. The server and client utilities are specified in Deliverable 3.4. Architecture and Specifications for Use Case 2: Secure Data Sharing and Analytics for Cyber Threat Intelligence.

This document is a user manual for Task 9.1. It establishes the backend server environments required to support the development of Use Case (UC) 1, including the wallet application, the issuance server, and a relaying party, initially without the FHE libraries, to realize the complete workflow.

Download Factsheet #5: Everyday Privacy—Real‑World Use Cases
From roadside checks to airport boarding and public services

This deliverable reports on the results of Task 3.4, describing considered scenarios for Use Case 2 in details, their architecture and the specification of the pilot.

This deliverable constitutes to release the of the FHE opensource library prividema-lib with low level operations GLWE and GGSW.

Download Factsheet #4: Privacy‑Preserving Cyber Threat Intelligence (CTI)

The paper “Accurate and Composable Noise Estimates for CKKS with Application to Exact HE Computation” was published in IACR Communications in Cryptology. The authors are Jean‑Philippe Bossuat, Anamaria Costache, Christian Mouchet, Lea Nürnberger and Juan Ramón Troncoso‑Pastoriza. This publication, developed within the PRIVIDEMA project, advances precise and composable noise estimation techniques for CKKS, enabling more reliable exact homomorphic computations.

The growing availability of personal data has driven major advances in machine learning, healthcare, and cybersecurity, but also increased privacy risks from re-identification attacks and rising legal and ethical demands. Differential privacy (DP) offers a principled framework to mitigate these risks. This review surveys DP’s foundations, mechanisms, and applications, focusing on privacy-preserving machine learning and synthetic data generation. It also discusses usability challenges
and the need for clearer communication and transparency in DP systems. The goal is to support informed adoption of DP in an evolving data privacy landscape.

The 1st Newsletter of the PRIVIDEMA project has been released. It presents the project`s objectives and the key achievements during the past few months.

The document specifies how FHE-based biometric authentication is integrated into the EUDI Wallet se-curity architecture to enable high-assurance user authentication for sensitive cryptographic wallet op-erations. The architecture separates on-device bio-metric capture and FHE encryption, ciphertext-do-main similarity computation at the WSCA, and hard-ware-secured decryption and policy decision at the WSCD/HSM.

This document provides a comprehensive specification of the APIs required for the PRIVIDEMA project’s Fully Homomorphic Encryption (FHE) framework. The report defines the structure and functionality of APIs supporting FHE schemes such as BFV, CKKS and TFHE, scheme switching and higher level functionalities such as Private Information Retrieval (PIR) and biometric authentication. The document also discusses the security requirements of the library.

This deliverable reports on the results of Task 3.2, providing considered scenarios for use case 2, their functional and technical requirements and KPIs.

This deliverable reports on the results of Task 3.1, providing a technical review of digital wallets and the requirements for developing FHE-based biometric authentication.

This deliverable presents the PRIVIDEMA`s communication kit, including the project’s visual identity as well as communication and dissemination materials.

Check out the PRIVIDEMA administrative poster, now available for dissemination and communication activities.

The official leaflet of the PRIVIDEMA project is available, containing project information, vision, goals of the project and more.

PRIVIDEMA will focus on developing user-friendly, scalable solutions to enhance cybersecurity across Europe. Find out more in the official announcement letter of PRIVIDEMA project.
