L-diversity: Privacy beyond k-anonymity
TL;DR: This paper shows with two simple attacks that a \kappa-anonymized dataset has some subtle, but severe privacy problems, and proposes a novel and powerful privacy definition called \ell-diversity, which is practical and can be implemented efficiently.

No free lunch in data privacy
TL;DR: This paper argues that privacy of an individual is preserved when it is possible to limit the inference of an attacker about the participation of the individual in the data generating process, different from limiting the inference about the presence of a tuple.
Journal ArticleDOI
Entity resolution: theory, practice & open challenges
TL;DR: This tutorial brings together perspectives on ER from a variety of fields, including databases, machine learning, natural language processing and information retrieval, to provide, in one setting, a survey of a large body of work.
Journal ArticleDOI
Pufferfish: A framework for mathematical privacy definitions
TL;DR: The Pufferfish framework can be used to create new privacy definitions that are customized to the needs of a given application and is introduced to allow experts in an application domain to develop rigorous privacy definitions for their data sharing needs.
