So first disclaimer: this isn't really something anyone in our group does, so I don't know much about it. I know a lot of developmental labs are using video chat. I checked
this recent Webinar, but I didn't see much about security, at least in skimming the transcript. Hyo Gweon has provided a comprehensive tutorial on
doing kid studies via Zoom.
I'm curious which security issues with Zoom you are referring to. Most of what I've heard about is Zoom-bombing; people who have permission to be in the meeting posting pornography or things like that.
Here is a post that has some details on how to protect yourself.
That said, you might try using Signal, which is specifically designed for security. WhatsApp is supposed to also be pretty good. See some info
here.
You are probably doing this, but don't forget to address the security of your data storage. I've known researchers who were very concerned about Web security while keeping identifiable data on an unsecured laptop that is connected to the Web. I wouldn't be surprised if in most labs, the primary security risk is post-collection.
Ultimately, nothing is totally secure, whether online or in person. I would consider both how valuable the information you are collecting is and how potentially damaging it is to your subjects. Are you interviewing North Korean dissidents about their upcoming coup plot? Because then you know there's a state actor who has the capability to break any system and who is highly motivated to gain this information. You're going to need more security than if you are asking random people about their summer vacation plans.
Speaking of, I would think about how to avoid collecting data during the call. That is, can you keep the discussion in the call anonymous and collect names and demographic information through a separate service? Basically, the best security against privacy violations is don't have private information. This would be true for in-lab studies. I don't normally check whether my lab has been bugged, but if I were working with North Korean coup plotters, I would! I'd probably also hire serious security.
I know that's not a precise answer. I don't think there are precise answers here. But hopefully these considerations are helpful. I also think reaching out to Hyo Gweon or Kim Scott (of LookIt) or some of the other people doing online kid interviews might land you some more info. If it does, please post what you learn here!
