"Google Turns to Retro Cryptography to Keep Data Sets Private"

An open source cryptographic tool, called Private Join and Compute, has been released by Google to bolster the privacy of confidential data sets. The multi-party computation (MPC) tool  was designed to help organizations with confidential data sets collaborate for research purposes without exposing their raw data. Through the use of this tool, each party can encrypt their data before they share it with each other. Each party would only be able to see results that can be used to discover commonalities, not the raw data. Private Join and Compute uses updated methods that were developed in the 1970s and 1990s. This article continues to discuss the methods and purpose of Private Join and Compute.
