Privacy and Security in P4 Medicine
P4 (Predictive, Preventive, Personalized and Participatory) medicine is called to revolutionize healthcare by providing better diagnoses and targeted preventive and therapeutic measures. However, to accelerate its adoption and maximize its potential, clinical and research data on large numbers of individuals must be efficiently shared between all stakeholders. The advent of quantum computers and the privacy risks stemming from disclosing medical data raise serious concerns, and have become a barrier that can hold back the advances in P4 medicine if effective privacy preserving technologies are not adopted to enable quantum-resistant privacy-conscious medical data sharing. The evolution of the regulation towards further guarantees (e.g., HIPAA in USA and the new GDPR in EU) reflects this urgent need.
DPPH has also produced a comprehensive software library, called Lattigo, that implements lattice-cryptography primitives supporting quantum-resistant homomorphic encryption.
Lattigo is fully written in Golang with no external dependencies, and it aims at enabling fast prototyping of secure-multiparty computation solutions based on multiparty homomorphic cryptosystems, by harnessing Golang’s natural concurrency model.
Lattigo is open-source, and its codebase and documentation can be found here: https://github.com/ldsec/lattigo
