DPKnob: A visual analysis approach to risk-aware formulation of differential privacy schemes for data query scenarios

Visual Informatics
Differential privacy is an essential approach for privacy preservation in data queries. However, users face a significant challenge in selecting an appropriate privacy scheme, as they struggle to balance the utility of query results with the preservation

Privacy-preserving Prediction

, 2018
Ensuring differential privacy of models learned from sensitive user data is an important goal that has been studied extensively in recent years. It is now known that for some basic learning problems, especially those involving high-dimensional data, producing an accurate private model requires much more data than learning without privacy.

Health data space nodes for privacy-preserving linkage of medical data to support collaborative secondary analyses

Frontiers in Medicine
IntroductionThe potential for secondary use of health data to improve healthcare is currently not fully exploited. Health data is largely kept in isolated data silos and key infrastructure to aggregate these silos into standardized bodies of knowledge is
