In our article “Database Reconstruction Is Not So Easy and Is Different from Reidentification”, we show that reconstruction can be averted by properly using traditional statistical disclosure control (SDC) techniques, also sometimes called legacy statistical disclosure limitation (SDL) techniques. Furthermore, we also point out that, even if reconstruction can be performed, it does not imply reidentification. Hence, the risk of reconstruction does not seem to warrant replacing traditional SDC techniques with differential privacy (DP) based protection. In “Legacy Statistical Disclosure Limitation Techniques Were Not an Option for the 2020 US Census of Population and Housing”, by Simson Garfinkel, the author insists that the 2020 Census move to DP was justified. In our view, this latter article contains some misconceptions that we identify and discuss in some detail below. Consequently, we stand by the arguments given in “Database Reconstruction Is Not So Easy:: :”.

对加芬克尔的反驳 (2023) – 用于保护 2020 年十年一次的美国人口普查的传统统计披露限制技术：仍然是一个可行的选择

在我们的文章“数据库重建并不那么容易，并且与重新识别不同”中，我们表明，可以通过正确使用传统的统计披露控制（SDC）技术（有时也称为传统统计披露限制（SDL）技术）来避免重建。此外，我们还指出，即使可以进行重建，也不意味着重新识别。因此，重建的风险似乎并不需要用基于差分隐私（DP）的保护来取代传统的 SDC 技术。在 Simson Garfinkel 所著的《2020 年美国人口和住房普查中不能采用传统统计披露限制技术》一文中，作者坚称 2020 年人口普查转向 DP 是合理的。在我们看来，后一篇文章包含一些误解，我们将在下面详细讨论这些误解。因此，我们支持“数据库重建并不那么容易:::”中给出的论点。
