Third-party cookies have been a privacy concern since cookies were first developed in the mid 1990s, but more strict cookie policies were only introduced by Internet browser vendor…
A novel analysis of utility in privacy pipelines, using Kronecker products and quantitative information flow
Mário S. Alvim, Natasha Fernandes, Annabelle McIver +2
We combine Kronecker products, and quantitative information flow, to give a novel formal analysis for the fine-grained verification of utility in complex privacy pipelines. The com…
Analyzing the Shuffle Model through the Lens of Quantitative Information Flow
Mireya Jurado, Ramon G. Gonze, Mário S. Alvim +1
Local differential privacy (LDP) is a variant of differential privacy (DP) that avoids the need for a trusted central curator, at the cost of a worse trade-off between privacy and…

Local differential privacy (LPD) is a distributed variant of differential privacy (DP) in which the obfuscation of the sensitive information is done at the level of the individual…
A Game-Theoretic Approach to Information-Flow Control via Protocol Composition
Mário S. Alvim, Konstantinos Chatzikokolakis, Yusuke Kawamoto +1
In the inference attacks studied in Quantitative Information Flow (QIF), the attacker typically tries to interfere with the system in the attempt to increase its leakage of secret…
