Conciliating Privacy and Utility in Data Releases via Individual Differential Privacy and Microaggregation
Jordi Soria-Comas, David Sánchez, Josep Domingo-Ferrer +2
-Differential privacy (DP) is a well-known privacy model that offers strong privacy guarantees. However, when applied to data releases, DP significantly deteriorates the analyti…
Multi-Dimensional Randomized Response
Josep Domingo-Ferrer, Jordi Soria-Comas
In our data world, a host of not necessarily trusted controllers gather data on individual subjects. To preserve her privacy and, more generally, her informational self-determinati…
Connecting Randomized Response, Post-Randomization, Differential Privacy and t-Closeness via Deniability and Permutation
Josep Domingo-Ferrer, Jordi Soria-Comas
We explore some novel connections between the main privacy models in use and we recall a few known ones. We show these models to be more related than commonly understood, around tw…
Individual Differential Privacy: A Utility-Preserving Formulation of Differential Privacy Guarantees
Jordi Soria-Comas, Josep Domingo-Ferrer, David Sánchez +1
Differential privacy is a popular privacy model within the research community because of the strong privacy guarantee it offers, namely that the presence or absence of any individu…
From t-closeness to differential privacy and vice versa in data anonymization
J. Domingo-Ferrer, J. Soria-Comas
k-Anonymity and ε-differential privacy are two mainstream privacy models, the former introduced to anonymize data sets and the latter to limit the knowledge gain that results from…
Utility-Preserving Differentially Private Data Releases Via Individual Ranking Microaggregation
David Sánchez, Josep Domingo-Ferrer, Sergio Martínez +1
Being able to release and exploit open data gathered in information systems is crucial for researchers, enterprises and the overall society. Yet, these data must be anonymized befo…
t-Closeness through Microaggregation: Strict Privacy with Enhanced Utility Preservation
Jordi Soria-Comas, Josep Domingo-Ferrer, David Sánchez +1
Microaggregation is a technique for disclosure limitation aimed at protecting the privacy of data subjects in microdata releases. It has been used as an alternative to generalizati…
Co-Utility: Self-Enforcing Protocols without Coordination Mechanisms
Josep Domingo-Ferrer, Jordi Soria-Comas, Oana Ciobotaru
Performing some task among a set of agents requires the use of some protocol that regulates the interactions between them. If those agents are rational, they may try to subvert the…
Improving data utility in differential privacy and k-anonymity
Jordi Soria-Comas
We focus on two mainstream privacy models: k-anonymity and differential privacy. Once a privacy model has been selected, the goal is to enforce it while preserving as much data uti…
