It looks to me that the only reason Google is pursuing "Privacy Sandbox" is because Chrome dominates the browser marketplace. (I put it in quotes because it neither preserves privacy, nor is it a sandbox). If I don't want 3rd-party cookies (I don't!) then I just toggle them off in Firefox. Sandbox is opaque in the sense that ordinary users can't hope to understand it; and a privacy guarantee is useless, if the user can't understand it. WTF is k-anonymity? I looked it up on Wikipedia, and I still don't understand it.
I guess that's why the Competition and Markets Authority is involved.
- jampekka 2y agok-anonymity means there must be at least k persons (or similar) that have identical data in the dataset. E.g. with k=5 there has to be at least 5 rows for each unique set of column values. It's easily broken if multiple such datasets are combined. And that's probably exactly what the commercial surveillance industry does.
- Nifty3929 2y agoK-anonymity is where you determine that you need at least K individuals in a group with a certain number of shared personal information such that you can't identify individuals within that group. For example, people >2m tall with January birthdays who's favorite color is red. If there was only one person in that group then you could identify them, so you shouldn't use that grouping. But if there are 1000 people in that group (in your dataset), then you can't ID them, so it's okay.
