Noise infusion banned from Census Bureau statistical products

Summary: A high-discussion front-page post (781 points) by differential-privacy researcher Damien Desfontaines argues against a legislative provision that would ban "noise infusion," the differential-privacy technique the US Census Bureau uses to protect respondent data in published statistics. The post explains how disclosure-avoidance noise works and why removing it raises reidentification risk. HN discussion split on the accuracy-versus-privacy tradeoff in published government data.
Comments: Commenters debated whether differential privacy degrades small-area statistics enough to justify the concern and whether alternative disclosure-avoidance methods would be mandated in its place.
