Differential Privacy: on the trade-off between Utility and Information Leakage [PDF]
, 2011 Differential privacy is a notion of privacy that has become very popular in the database community. Roughly, the idea is that a randomized query mechanism provides sufficient privacy protection if the ratio between the probabilities that two adjacent ...

Differential Privacy as a Mutual Information Constraint [PDF]
, 2016 Differential privacy is a precise mathematical constraint meant to ensure privacy of individual pieces of information in a database even while queries are being answered about the aggregate. Intuitively, one must come to terms with what differential privacy does and does not guarantee.

Position Paper on Simulating Privacy Dynamics in Recommender Systems [PDF]
arXiv, 2021 In this position paper, we discuss the merits of simulating privacy dynamics in recommender systems. We study this issue at hand from two perspectives: Firstly, we present a conceptual approach to integrate privacy into recommender system simulations, whose key elements are privacy agents. These agents can enhance users' profiles with different privacy

Bounded-Leakage Differential Privacy [PDF]
, 2020 We introduce and study a relaxation of differential privacy [Dwork et al., 2006] that accounts for mechanisms that leak some additional, bounded information about the database.

Understanding How to Inform Blind and Low-Vision Users about Data Privacy through Privacy Question Answering Assistants [PDF]
arXiv, 2023 Understanding and managing data privacy in the digital world can be challenging for sighted users, let alone blind and low-vision (BLV) users. There is limited research on how BLV users, who have special accessibility needs, navigate data privacy, and how potential privacy tools could assist them.
