Cryptographically Secure Data Analysis for Social Good

Thursday, January 18, 2018 - 11:00 am11:30 am

Mayank Varia, Research Scientist, Boston University


This talk describes our experience deploying a web application that securely analyzed the (sensitive!) salary data of 112,600 employees in the Greater Boston Area in order to calculate pay disparity across gender and race. We use a cryptographic tool called secure multi-party computation in order to balance transparency with confidentiality; this tool allows us to analyze the data without ever learning any person or company's salary information. Our experiences demonstrate that cryptographically secure data analysis over sensitive data can provide significant social benefits in contexts where data sharing is constrained or prevented by legal, ethical, or privacy restrictions.
