How to utilize data without compromising privacy thus becomes a pressing research question. An important transformative technology that allows for privacy preserving data processing is secure computation. In secure computation, one computes arbitrary functions directly on encrypted data. It hides all information about the data against untrusted parties, even if the untrusted parties are involved in the computation. Achieving secure computation is challenging, but if feasible it would benefit many domains. For example, two online retailers want to find correlations between products bought by their common customers to boost sales, without revealing customer or unnecessary sales information; policy makers want to link healthcare data held by public hospitals and private healthcare providers without leaking patient data, and geneticists want to compare DNA samples held by them and others to identify mutations that may cause cancers, again without loss of patient privacy. Secure computation addressed the tension between data utilization and privacy in all those scenarios.
The most important challenge in secure computation is to achieve efficient scalability. That is, how to design protocols that are efficient enough to scale to large datasets, as is needed in most real world applications? A secure computation protocol is often tens of thousand times slower than computing in the clear. Such loss of computational efficiency is not acceptable for most application.
The goal of this proposed research is to strike the right balance between security and scalability, and design, prove, implement and evaluate practical secure computation protocols that allow the processing huge volumes of data belonging to different parties in reasonable time.
