Swellfish privacy: Supporting time-dependent relevance for continuous differential privacy
作者：
Highlights：
• Swellfish Privacy — a privacy definition for publishing high-utility differentially private query results over streams.
• Notions to respect quickly changing time-dependent human privacy needs.
• Effects resulting from time-dependent privacy needs that allow to tune utility.
• Tools to design high-utility mechanisms easily that exploit the effects.
• Mechanism instances using these tools.
• A realistic case study revealing significant improvements over existing competitors.
