Read Technology preview: Private contact discovery for Signal by moxie0 (Signal)
At Signal, we’ve been thinking about the difficulty of private contact discovery for a long time. We’ve been working on strategies to improve our current design, and today we’ve published a new private contact discovery service. Using this service, Signal clients will be able to efficiently and scalably determine whether the contacts in their address book are Signal users without revealing the contacts in their address book to the Signal service.
There’s a lot of work involved here, but this is an intriguing proposition for doing contact discovery in social media while maintaining privacy. I can’t wait to see which silos follow suit, but I’m even more curious if any adventurous IndieWeb creators will travel down this road?
