Individuals appearing in videos on any platform or TV station can self-authenticate by QR-signing their own speech with a private key.
DeepFakes suck. For one thing, people can create fake videos of you. A side effect is that people might not even trust your authentic content, because they're worried it's a fake. How can we empower everyday people, celebrities, and community leaders to prove their own identities whenever they appear in a video?
Enter WordSig! WordSig is a (very simple) protocol for generating QR streams that digitally sign your words as you speak. If you display the stream in any video — even one that someone else is recording — viewers of the video will be able to check that the words are being signed with your private key. The signatures can't be copied or pasted onto other words without verifiably destroying their validity. It's kind of magical, in the way digital signatures are always kind of magical 🙂
The idea for the WordSig app came from academia; someone still needs to build it! Salary is negotiable based on your experience, starting at $150k/year. Apply here if you think you might be up to the task!
