Master’s Thesis Presentation • Cryptography, Security, and Privacy (CrySP) • Differential Privacy for Nearest Neighbor Queries

Please note: This master’s thesis presentation will take place online.

Emily Lepert, Master’s candidate
David R. Cheriton School of Computer Science

Supervisor: Professor Florian Kerschbaum

We examine the problem of providing differential privacy for nearest neighbor queries. Very few mechanisms exist that achieve this, most notable geo-indistinguishability in the context of location privacy. However it uses an extended definition of differential privacy and restricts the sensitivity of queries.
