Abstract: A time series is a sequence of values indexed in a discrete time order. Time series analysis has numerous applications big data analytics. However, many time series originate from personal data, such as biosensors in telecare, IoT sensors in smart home, and trajectories for mobility tracking in COVID-19 pandemic. Directly releasing them to the public can cause privacy infringement. To address this issue, many privacy-preserving time series publishing techniques have been proposed, among which differential privacy (DP) provides rigirous privacy guarantee for individual data and has been regarded as a golden standard for privacy protection. This talk first introduces the rationale of DP model, then presents our recent work on time series data release with DP, and finally identifies some open problems and research directions in this community.
