Proposing the Independent Component Laplace Process (ICLP) mechanism for differential privacy in functional summaries.
要約
The article introduces the ICLP mechanism for privacy in functional summaries, addressing limitations of existing mechanisms. It discusses feasibility, statistical estimation problems, and utility enhancement through oversmoothing. The content covers differential privacy, functional data analysis, and privacy-safe regularization. Various theorems and methodologies are presented for privacy protection in different scenarios.
