Hi HN. This all started when I was targeted by one of those fake video call schemes we hear so much about lately. I was invited into a video call with someone posing as a person I’d met at a conference, and I was close to being fooled before their “audio problems” became increasingly suspicious. When Tavus announced its Griffin-Lite model last month, they claimed 48% of callers mistook it for a human. I think to avoid future scenarios like my own, it’s clear we need irrefutable proof of who’s on the other side of your call and not simply a judgement call.
So I’ve been working these last few months on a solution that proves the person on the other side of a call is using a genuine camera and is who they say they are, without sacrificing privacy and avoiding the pitfalls of using detection.
The result is Apertrue Witness. You can find details on how it works in the first comment, on the landing page, and full technical detail here (https://witness.apertrue.photo/how).
Witness is live today on macOS 27+ and iPhone (https://witness.apertrue.photo/download, Windows and Android coming soon). You can check out a previously verified call here: https://witness.apertrue.photo/verify/sample and the verifier here: https://github.com/Apertrue/witness-verify. It’s free while we complete our independent audit.
