New Publication: Privacy-Preserving Hyperparameter Tuning for Federated Learning The paper "Privacy-Preserving Hyperparameter Tuning for Federated Learning," authored by Natalija Mitic, Apostolos Pyrgelis and Sinem Sav, explores privacy risks in federated learning hyperparameter tuning and introduces PRIVTUNA, a framework using multiparty homomorphic encryption to ensure confidentiality while optimizing model performance. This research, part of the #HARPOCRATES project, evaluates strategies for secure hyperparameter tuning in both IID and non-IID federated learning settings, with applications in privacy-sensitive domains.

The Privacy vs. Innovation Debate: Can We Have Both? In today’s data-driven world, organizations face a difficult challenge: How do we leverage data to drive innovation while ensuring #privacy and #security? On one hand, data sharing fuels progress—it enables better #AI models, smarter #healthcare, and more efficient #digital services. But on the other hand, data #privacy is non-negotiable—especially when dealing with sensitive personal, financial, or medical information. So, how can we strike a balance? This is where Hybrid Homomorphic Encryption (#HHE) comes into play. Unlike traditional #encryption, which protects #data only at rest or in transit, #HHE allows computations to be performed directly on encrypted data—without ever decrypting it. This means organizations can collaborate, share insights, and even perform AI-driven analyses without exposing sensitive #information. At #HARPOCRATES, we are advancing privacy-preserving technologies like HHE to unlock new possibilities: ?? AI models can be trained on encrypted datasets, ensuring data privacy in machine learning. ?? Healthcare institutions can share research insights without revealing patient records. ?? Businesses can analyze customer trends without compromising individual privacy. By leveraging #cryptographic innovations, we’re proving that #privacy and #innovation don’t have to be at odds—they can (and should) go hand in hand. What do you think? Can encryption be the key to a more secure yet data-driven future? Let us know your thoughts below! ?? #DataSecurity #PrivacyTech #Encryption #HARPOCRATES #AI #CyberSecurity Tampere University, University of Westminster, RISE Research Institutes of Sweden, Trilateral Research, Zentrix Lab, CanaryBit, Charité - Universit?tsmedizin Berlin, Universit?tsmedizin G?ttingen, SARGA (Sociedad Aragonesa de Gestión Agroambiental S.L.U.), Regione Veneto, University of Eastern Finland, Université Paris Cité médecine, S2GRUPO

Celebrating Women and Girls in Science! Today, on International Day of Women and Girls in Science, we celebrate the contributions of women in #research, #technology, and #innovation. At?#HARPOCRATES, we support diversity in #STEM and recognize the impact of #women in shaping a more secure and privacy-aware digital future.

What if... Imagine a world where trust and transparency define how data is shared and used. What if: - Governments could collaborate on critical security threats while ensuring sensitive information remains private? - Organizations could share real-time threat intelligence without risking their proprietary data? - Citizens’ personal data stayed protected, even during cross-border data exchanges? With #HARPOCRATES, this vision is becoming a reality. Our project focuses on enabling secure, privacy-preserving data sharing for threat intelligence and beyond. Through cutting-edge cryptographic solutions, #HARPOCRATES supports secure collaboration between governments and industries to protect public and national security. What if secure data sharing was the key to a safer, more collaborative world? Join us as we redefine the boundaries of trust and privacy.
