Ask HN: Are photos unique enough to use as QR codes?

1 点作者 quantum2022大约 1 年前
I had a dream where I was holding a photograph that when you looked at it moved like a video. That spurred this idea where you could print a photo off of a video at any time during the video and then if you scanned the photo with your phone it would take you to the video. Could that be possible in the future? I know you could have a QR code in the corner of the photo perhaps, I just wasn't sure if a photo would be unique enough to use as an identifier somehow. Thanks.

Using an image as a search key is possible now. Google has a reverse image search and photo sites like Getty regularly search for people plagiarizing thier ip.<p>It seems reasonable to st sometime it will be possible to find a video from a still in a similar way to finding an audio track from a small clip.
