Federal Data Sharing and Analysis for Social Utility<\/h1>\n\n\n\n

Summary:<\/strong> The availability of large volumes of user data combined with tailored statistical analysis presents a unique opportunity for organizations across the spectrum to adapt and finetune their services according to individual needs. Having shown remarkable results in analyzing user data, machine learning models attracted global adulation and are applied in a plethora of applications including medical diagnostics, pattern recognition, and threat intelligence. However, such service improvements and personalization based on user data analysis come at the heavy cost of privacy loss. Furthermore, practice showed that systems that use such models incorporate proxies that are often inexact, biased, and often unfair.<\/p>\n\n\n\n

In HARPOCRATES, we focus on setting the foundations of digitally blind evaluation systems that will, by design, eliminate proxies such as geography, gender, race, and others and eventually have a tangible impact on building fairer, democratic, and unbiased societies. To do so, we plan to design several practical cryptographic schemes (Functional Encryption and Hybrid Homomorphic Encryption) for analyzing data in a privacy-preserving way. Besides processing statistical data in a privacy-preserving way, we also aim to enable a richer, more balanced, and comprehensive approach where data analytics and cryptography go hand in hand with a shift towards increased privacy.<\/p>\n\n\n\n

In HARPOCRATES, we will first show how to effectively combine cryptography with the principles of differential privacy to secure and privatize databases. Next, we will build privacy-preserving machine learning models able to classify encrypted data by performing high-accuracy predictions directly on ciphertexts across federated data spaces. Finally, to demonstrate how these solutions respond to users\u2019 needs, we will implement two real-world cross-border data-sharing scenarios related to health data analysis for sleep medicine and threat intelligence for local authorities.<\/p>\n\n\n\n
