Is there a way that a person could create a QR code made from one-way private key? The QR code would contain date and time and other Metadata that is decrypted with a public key that proved the QR code in the video was made by, for example, the person in the video? This would "prove" the video was real? I guess the speech would still be manipulated. So the whole transcript would have to be encrypted in this way...
- lucb1e 8y agoI don't know why you're talking about QR codes and transcripting/encrypting the audio when you can just sign the file? gpg --sign video.mp4
- misnome 8y agoI assume they are talking about signing/watermarking a video in a way that survives video encoding/lossy transmission. A QR code probably wouldn’t work for various reasons but is an easy mental analogy to think of.
- lucb1e 8y agoFor embedding, you should just put it in the metadata. Encoding it in the video itself... I don't really see the point.
