Privacy, Mobility, & Policy: Understanding Re-identification Risks in Mobility Data

Privacy, Mobility, & Policy

Understanding Re-identification Risks in Mobility Data


About this webinar

Questions of how re-identifiable mobility data is—and whether individual location traces can be sufficiently anonymized—have become increasingly prominent as governments around the world seek to utilize mobility data for various policy and regulatory purposes. To de-mystify this issue, Privacy Analytics recently conducted a study in partnership with Uber to quantify the privacy risks associated with government access to individual-level mobility data. This webinar expands upon the findings of this collaboration and provides insight into the broader context and importance of this research in the mobility sector.

Watch the webinar and download a copy of Privacy Analytics’ summary report, which evaluates the re-identification risks of Uber’s dataset for California Public Utilities Commission (CPUC).
