An Information Hierarchy of Privacy Filters and Odometers
Sophie Taylor, Praneeth Vippathalla, Justin P. Coon
In sequential data analysis, privacy loss accumulates over time, and privacy filters and odometers are used to control and track this cumulative cost. We study how the information…
Realisation-Level Privacy Filtering
Sophie Taylor, Praneeth Vippathalla, Justin Coon
We study differentially private data release, where a database is accessed through successive, possibly adaptive queries and mechanisms. Existing composition theorems and privacy f…
Adaptive Privacy of Sequential Data Releases Under Collusion
Sophie Taylor, Praneeth Kumar Vippathalla, Justin Coon
The fundamental trade-off between privacy and utility remains an active area of research. Our contribution is motivated by two observations. First, privacy mechanisms developed for…
The Asymptotic Behaviour of Information Leakage Metrics
Sophie Taylor, Praneeth Kumar Vippathalla, Justin P. Coon
Information theoretic leakage metrics quantify the amount of information about a private random variable that is leaked through a correlated revealed variable . They can be…
