Not trying to be snarky, and perhaps it wasn't well stated, but the last paragraph I said I'm concerned about identification via my writing style. If they have my emails, they would have my writing style. It doesn't have to be tied to PII there, they can cross reference it with my blog. I'm speculating because I read that you can identify people by a few sentences of their writing.
reply"Deidentification" seems really murky and imprecise at best.
Reidentification via writing style is definitely possible, and I doubt the vendor will modify things in a way sufficient to handle that.
replyBut I think this is a place where we should apply bounded distrust: there are lots of places where we should distrust Google, but reidentifying people in an explicitly deidentified dataset isn't one of them.
You have to trust that this really "deidentifies". Time and time again it was shown, that the measures taken were not enough to anonymize.
replyE.g. the parent wrote that he fears, he could be identified by his writing style, which is totally plausible. How would you "deidentify" this?
Even if they follow to the letter a deidentification process, Google and Meta have so much data about individuals that re-identification shouldn't be very hard for the majority of airline passengers' data they put their hands on.
replyOf course, takes a lot more effort than not doing proper deindetification in the first place but if they wanted to appear like caring about data privacy they still have enough data points to correlate the sets later on (and/or over time).
No such animal.
replyI have a bridge for sale, hardly seen use, pay me ${money} and you can collect it in New York City. Interested?
