But the same MS researcher that developed "differential privacy" has said and explained how its not really effective except for in short terms studies. I'm surprised a publication coming from MIT would not bring that up. It seems like its just "clever" marketing on Apples part. Also Chrome already employees "differential privacy" for w/e thats worth.

Do you have a quote for the first point? It doesn't sound (i) correct, or (ii) like something Cynthia would say.

Its inherent in the understanding of what "differential privacy" is. But please listen to her explain it herself, http://www.sciencefriday.com/segments/crowdsourcing-data-whi...

Basically, its either your statics approach meaninglessness and maintain the individuals privacy or "overly accurate estimates of too many statistics is blatantly non-private"

More so, is there proof of the second quote that Chrome uses differential privacy?

Not sure if this[0] is exactly what you're looking for but, I think it's baked into chromium[1].

It's mentioned in the article: RAPPOR.

Apple and their PR, as always.
