- Authors: Ferdinando Fioretto, Cuong Tran, Pascal Van Hentenryck,
- Abstract summary: The U.S. Census Bureau releases data sets and statistics about groups of individuals that are used as input to a number of critical decision processes.
To conform to privacy and confidentiality requirements, these agencies are often required to release privacy-preserving versions of the data.
This paper studies the release of differentially private data sets and analyzes their impact on some critical resource allocation tasks under a fairness perspective.

- Abstract: Agencies, such as the U.S. Census Bureau, release data sets and statistics about groups of individuals that are used as input to a number of critical decision processes. To conform to privacy and confidentiality requirements, these agencies are often required to release privacy-preserving versions of the data. This paper studies the release of differentially private data sets and analyzes their impact on some critical resource allocation tasks under a fairness perspective. {The paper shows that, when the decisions take as input differentially private data}, the noise added to achieve privacy disproportionately impacts some groups over others. The paper analyzes the reasons for these disproportionate impacts and proposes guidelines to mitigate these effects. The proposed approaches are evaluated on critical decision problems that use differentially private census data.

This paper shows that surveys of important societal relevance introduce sampling errors that unevenly impact group-level estimates.
To address these issues, this paper introduces an optimization approach modeled on real-world survey design processes.
Privacy-preserving methods used to determine sampling rates can further impact these fairness issues.

This paper characterizes the impact of Differential Privacy on bias and unfairness in the context of releasing information about networks.
We consider a network release problem where the network structure is known to all, but the weights on edges must be released privately.
Our work provides theoretical foundations and empirical evidence into the bias and unfairness arising due to privacy in these networked decision problems.

In the second, an attacker uses a threshold that accounts for the effect of the data release on the separation in scores between individuals.

We consider partial differential privacy (DP), which allows quantifying the privacy guarantee on a per-attribute basis.
In this work, we study several basic data analysis and learning tasks, and design algorithms whose per-attribute privacy parameter is smaller that the best possible privacy parameter for the entire record of a person.

It proposes a novel post-processing mechanism that is (approximately) optimal under different fairness metrics.
