Differentially Private Fair Division. (arXiv:2211.12738v1 [cs.GT])

Fairness and privacy are two important concerns in social decision-making
processes such as resource allocation. We study privacy in the fair allocation
of indivisible resources using the well-established framework of differential
privacy. We present algorithms for approximate envy-freeness and
proportionality when two instances are considered to be adjacent if they differ
only on the utility of a single agent for a single item. On the other hand, we
provide strong negative results for both fairness criteria when the adjacency
