Well, during the pandemic, we fundamentally refused this false dilemma, this false trade-off between the public good (like contact tracing) on one side and privacy on the other side. During the pandemic in Taiwan, if you entered a venue, you saw a QR code. If you scanned it, it texted a 15-digit random number generated by the venue to 1922, the well-known telecom number for pandemic response. And the thing is, because this is a random number, your telecom actually didn’t know where you had been. When you show that you have texted the number 1922, the venue learns nothing about your phone number or anything about you. It’s called zero-knowledge.
