Data Structures for Data Privacy: Lessons Learned in Production

Friday, June 24, 2022 - 2:15 pm2:40 pm

Dr. Rebecca Bilbro and Dr. Benjamin Bengfort, Rotational Labs


In this talk we present a decentralized messaging protocol and storage system in use across North America, Europe, and South East Asia. Built at the behest of an international nonprofit working group, the protocol and system are designed to address a unique problem at the intersection of financial crime regulation, distributed ledger technology, and user privacy. In our talk we discuss the many lessons learned in the process of architecting, implementing, and fostering adoption of this system. We present the Secure Envelope, a data structure that employs a combination of methods (symmetric and asymmetric encryption, mTLS, protocol buffers, etc) to safeguard data privacy both at rest and in flight.
