Kim has been with Visa since September 2002 and with Visa Research since April 2019. Kim is a security architect who has worked as a crypto, security, and biometrics subject matter expert throughout his tenure at Visa, most recently leading the Applied Authentication Lab, designing authentication solutions that give great user experiences while preserving customers’ privacy.
Kim has a variety of other experiences, such as building a public key infrastructure in a Swiss mountain, working at Mondex creating a digital currency without blockchains, using blockchains for settlement, and in the distant past working on models of programming languages, denotational semantics, formal methods and designing a specification language. He has a Ph.D. in computer science from Carnegie Mellon University.
Kim represents Visa on the EMV Security Working Group, in the Cryptographic Review Forum, and chairs the ISO subcommittee on Security in Financial Services, which among other things define how PINs should be protected across the world, and how cryptographic keys should be managed in the financial services industry.
Right now Kim is most excited about privacy preserving biometrics and other practical Visa use cases for multi-party computation, and at the same time trying to understand quantum computation, specifically (1) how best to design algorithms that utilize the vast potential of quantum mechanical phenomena, and (2) how to track and measure progress towards building a scalable quantum computer.
