Thanks a lot for your time.

You need to query information and only get back without letting them know what you’re querying, and so forth. I’d be very happy to talk to you in the future.

Very interesting. About all the other things, in a usual day, like federated learning or differential privacy, the work we’re doing with MPC and homomorphic encryption. It’s a big anti-money-laundering type of use or form of encryption, which is very similar to what you need here.

Absolutely. So, are you working with the Israelis?

Do you find that there’s a lot of people coming to you for finding out, like what I’m doing right now, what you’ve done?

You say as a result of SARS…

Oh, I see. Everybody gets quarantined unless they have symptoms. Then they go to the hospital.

Any thoughts about that? That there are people your system didn’t check mark as going into quarantine?

Yeah, there has been talk about that. Certainly there is some upside to this shelter-in-home. One other thing that is not privacy related, but when I read about it in the beginning, is that you were checking for symptoms of people arriving to Taiwan. As far as they understand now, ...

Eventually there has to be some kind of…We want to continue with this idea that we can travel globally and do business globally. It requires being the right person. It has to be some thinking about how much…

Again, the social privacy of your citizens, protected by your constitution…

In terms of international collaboration, there’s the Taiwan system and then people are leaving Taiwan saying they’re going to another airport, whether they’re doing it now or not doing it in the future. There’s going to be a lot of travel, so there has to be a lot of collaboration ...

There is a system here, and obviously it’s been successful. Are there statistics? Tell me about this application that the telecom company has about the quality of this proximity-checking. Is there any kind of feedback from this experiment?

Those are the people who haven’t been quarantined. For people who have been quarantined, then it’s a weird question. You know that they’re part of the system, the governmental system that wants to make sure that they were being monitored and is able to track their movements.

Essentially, what you’re saying is that the privacy issue then are between the telephone company, which has the information anyway, and yourself.

True. The assumption here is that people are going to report – in some sense, take care of themselves, or go and ask for masks.

My question is, how do you enforce that?

Still, let’s say they were exposed. Now they know that they were exposed, because their phone tells them that. At this point, they are at risk. They are a risk to society, possibly, because they can transmit it further.

On my phone, within my phone, I can tell when I was in proximity, also when I should be, but it’s not only me that knows it. That information also goes to…

You’ve probably have heard this particular idea of a scheme, just because it’s probably the first thing people come up with. Your phone generates some random numbers every time it’s in a location, just a random number and location. Later, people who have been in the same…if you get sick, ...

The thing is, I guess that the issues that people are dealing with right now is, who is doing the recording? Who’s entitled to that information? Obviously, the telephones companies have that information. The other question is does it ever leave the phone or doesn’t leave the phone?

This part of finding out whether they overlapped with someone else’s phone, that means you want to have access to the information of the other phones as well, and then checking whether the GPS are in the same place, to be defined, or the Bluetooth. It talks about…

Like you said, they went to the store or something because they need to.

They’re the people went to the border, you say, and now they’re in quarantine, and now you want to make sure that they are not leaving the quarantine, or if they are, who they’re meeting, or that’s not a question at all. At that point, it was just a question ...

Good. This made sense early on, where you could control some of the people who would go into quarantine.

I guess what I meant is not that you’re collecting new data, is that you’re processing data on everyone, or you’re processing the data on people who…?

What’s deemed to be necessary and what’s not deemed to be necessary.

Even when you talk about this, saying that the law says that you are allowed to collect information in this particular case, a virtual collection, as long as it helps protect the patient himself or the public, then there’s a question of whether even there there’s a restricted amount of ...

You want to know very accurate information, which is in very high resolution. My question is, when you said you already did some legwork because of SARS, to go through the constitutional process, and to see what’s acceptable, not acceptable. Does this mean what level of privacy is acceptable, or ...

Actually, the things you’ve mentioned, federated learning and differential privacy, as you’ve said, these are great areas of research, great areas to use theoretical techniques in practice and maybe get less accuracy. It doesn’t matter in the applications that mostly you would be using. Here, this is not the case, ...

Early on, I guess, my expectation would have been that you would have been the second-hard hit after China.

What is the situation right now?

Thanks a lot for your time.
