minutephysics explains how differential privacy uses mathematical noise to protect individual data in the US Census.

What people say. Recommended as a great walkthrough of the privacy doom principle and how differential privacy works.

On “Cohort IDs can be collected over time to create cross-site tracking IDs”

Your comment reminded me of this minutephysics video about the census. link to this video It a great walkthrough of the "privacy doom principle."

On “Why the 2020 census has 9 fake people in a single house”

Technical explanation by minutephysics: link to this video The amount of privacy is configurable, and researchers who would like to tune it (in either direction) can make a plea so the public can decide the amount of privacy loss they're willing give up in order to aid research. Each culture is different and has different tolerances for privacy and amount of intrusiveness.

On “Google tracks individual users per Chrome installation ID”

> That would make the existence of anonymous data practically speaking impossible to have on the web For almost every type of data that is true. Transforming or substituting data doesn't make it anonymous; the patters in the data are still present. To produce actually anonymous data you have to do what the GDPR instructed: corrupt the data ("rendered anonymous") severely enough that the "data subject is ... no longer identifiable". You need to do something like aggregate the data into a small number of groups such that individual records no longer exist. Techniques like "differential privacy" let you control precisely how "anonymous" your data is by e.g. mixing in carefully crafted noise. >…
