“…In Francis (2022) it is shown that race and ethnicity can be inferred with more precision and less prior knowledge from TDA outputs than from the outputs of the Census previous protection algorithm. An alternative has also been proposed by Ruggles (2021) to investigate the impact of reconstruction on reidentification. The idea is to first match the external database to the reconstructed census data.…”

Database Reconstruction Is Not So Easy and Is Different from Reidentification

In recent years, it has been claimed that releasing accurate statistical information on a database is likely to allow its complete reconstruction. Differential privacy has been suggested as the appropriate methodology to prevent these attacks. These claims have recently been taken very seriously by the U.S. Census Bureau and led them to adopt differential privacy for releasing U.S. Census data. This in turn has caused consternation among users of the Census data due to the lack of accuracy of the protected outputs. It has also brought legal action against the U.S. Department of Commerce. In this article, we trace the origins of the claim that releasing information on a database automatically makes it vulnerable to being exposed by reconstruction attacks and we show that this claim is, in fact, incorrect. We also show that reconstruction can be averted by properly using traditional statistical disclosure control (SDC) techniques. We further show that the geographic level at which exact counts are released is even more relevant to protection than the actual SDC method employed. Finally, we caution against confusing reconstruction and reidentification: using the quality of reconstruction as a metric of reidentification results in exaggerated reidentification risk figures.

“…Carpenter and Ruggles have independently noted that the mechanical energy input to the mercury from the ''instantaneous'' energy deposition from the beam scales as the square of the incident beam energy [15,16]. They argue that both the pressure rise (Dp) and the volume expansion (DV) required to relieve the pressure scale directly with beam power deposition (Q).…”
