ZØ: an optimizing distributing zero-knowledge compiler
Matt Fredrikson, Benjamin Livshits · 2014
Applications increasingly rely on privacy-sensitive user data, but storing user’s data in the cloud creates challenges for the application provider, as concerns arise relating to the possibility of data leaks, responding to regulatory pressure, and initiatives such as DoNotTrack. However, storing data in the cloud is not the only option: a recent trend explored in several recent research projects has been to move functionality to the client. Because execution happens on the client, such as a mobile device or even in the browser, this alone provides a degree of privacy in the computation, with only relevant data disclosed to the server. However, in many cases moving functionality to the client conflicts with a need for computational
