Why not just sign the content with a digital signature?

  You mean devices could sign the images they create and then wherever someone publishes the picture you'd be able to validate the signature using that device's (published somewhere) public key? That would be cool indeed. Except it wouldn't change anything. Facebook doesn't care about fakes and people wouldn't care whether the picture someone shared hasn't been tampered. Also whoever manipulated the picture could just sign it again probably.

    Some people do care about authenticity though, hence the genesis of the OP's work to try and authenticate and it's why people still read news papers vice trusting their clickbait Google "news" feed. I'm just saying that I'd trust some encryption cert (whatever it is) traced back to a known more reputable source (say Financial Times and the like) than an algorithm that is just guessing that a photo/video is an un-altered genuine original vice a fake. The challenge is establishing an author's credibility in the first place. If I trace a cert back to joe schmo off the street or some empty front business, then I'd probably not trust the content.

  Because then you would lose in the buzzword bingo game.
