But the bank and the horn content provider could collude and that would let the bank know that you're watching horn (shame, shame!).

The ZKP approach aims to prevent this attack method.

Chase.com currently is using:

mPulse

Google Marketing Platform Meta

LinkedIn Ads

Trade Desk

Aggregate Knowledge (Trans Union)

Adobe Audience Manger

Can you elaborate on how the risk of ironbank and hornpub colluding by de-anonymizing you via rainbow tables or IP forensics is substantially greater than Chase and PornHub using - Google Marketing?

It isn't, but due to bureaucracy, when designing a solution, it's that solution that has to be "secure" without really considering that the current outside situation is already insecure..

Anyway I'm not advocating for this solution, just addressing the question directly.

Thanks for the feedback.

I don't see this as the end all ultimate solution for age verification. I see it more as a tourniquet; imperfect - but better than bleeding to death.
