That's correct. People would be surprised at the number of HIPAA violations that happen everyday. It is, however, among the strongest and most well-enforced data privacy laws (in the US).
> True, but that doesn't mean that Google is the right entity to do this. In my opinion, they're the wrong entity, because Google is not exactly trustworthy.
You're certainly right to be concerned. I don't share your opinion about Google per se, but this is important data for our society. I'd argue that OpSec at a large provider--let's say Microsoft--is more sophisticated than a start-up. So how does an organization decide who is the "right" entity to deal with?
> But they're Google. What this sort of thing means for me is that I need to start asking medical providers if they're participating in this sort of thing with Google (or other companies that I consider bad actors), so I know which ones to avoid using.
If this is important to you, I would strongly encourage it. Our health industry is better when consumers are better informed, and can make informed decisions. Personally, it's more important to me to be able to actually know how much a procedure is going to cost rather than who owns the AI stack behind their clinical decision support system.
