The COVID-19 pandemic exposed both the potential and the limitations of digital contact tracing. The UK’s NHS COVID-19 app, launched as part of the public health response, became a widely discussed case study in how technology, policy, and privacy intersect…

Contact tracing emerged as one of the most critical public health tools during the COVID-19 pandemic. It helped authorities and healthcare systems interrupt chains of transmission, identify outbreaks early, and provide timely care to those at risk. But alongside its…

The fields of Zero-Knowledge Proofs (ZKPs) and Secure Multiparty Computation (MPC) are often studied separately—but what if one could be built from the other? In the foundational paper “Zero-Knowledge from Secure Multiparty Computation” by Ishai, Kushilevitz, Ostrovsky, and Sahai (SIAM…

In the evolving landscape of privacy-enhancing technologies, Multiparty Computation (MPC) and Zero-Knowledge Proofs (ZKPs) stand out as two foundational cryptographic tools. While often seen as addressing distinct privacy goals, they are increasingly being combined to achieve stronger guarantees of privacy,…

Multiparty Computation (MPC) is a cornerstone of modern cryptography, enabling collaborative data analysis without compromising privacy. As outlined in the IEEE Digital Privacy article (2024), MPC is no longer just a theoretical construct—it’s an increasingly deployed method for secure, decentralized…
