Descripción del proyecto
Análisis de datos y criptografía para preservar la privacidad
A fin de responder a las necesidades de los clientes, las organizaciones se basan en grandes volúmenes de datos de usuarios combinados con análisis estadísticos a medida para adaptar sus servicios en consecuencia. Se están empleando modelos de aprendizaje automático en aplicaciones. Sin embargo, estas mejoras del servicio y la personalización basada en el análisis de los datos del usuario aumentan el riesgo de pérdida de privacidad. Además, los sistemas que emplean estos modelos incorporan a menudo variables sustitutivas inexactas, sesgadas e injustas. En el proyecto HARPOCRATES, financiado con fondos europeos, se sentarán las bases de sistemas de evaluación digitalmente ciegos diseñados para eliminar dichas variables. El equipo del proyecto tiene previsto diseñar varios esquemas criptográficos prácticos (cifrado funcional y cifrado homomórfico híbrido) para analizar los datos de manera que se preserve la privacidad y se pueda adoptar un método integral en que el análisis de datos y la criptografía se asocien con una mayor privacidad.
Objetivo
Availability of large volumes of user data combined with tailored statistical analysis present 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.
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. In HARPOCRATES we will first show how to effectively combine cryptography with the principles of differential privacy to secure and privatise 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’ 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.
