Context for this discussion: Anonymized version of Sally's "Road Warrior" travel data, e.g., sent to London Transport or CalTrans. Anonymization (through scrubbing/removing PII, aggregated data), data may be unclassified (space-time travel data), should have (average distance traveled, stops/starts, vehicle classification), should not have (PII). Open questions: Sally as driver. Eve: more stuff becomes PII over time, data security is a spectrum, caution not to overpromise. Joe: data contained identifiers. Eve: source of data can be correlated. Not counting on cryptographic techniques to save us. Joe: aggregation and statisticly relevant data can provide anonymization. All: hard to assure anonymity, can be explilcit steps to de-personalize data. Depersonalization is objective, anonymization is subjective. Is a process, not an end-state.
