Living in a world where we only trust photos from official photojournalists because everything else may have been doctored is not a good outcome.

  We already live in a world we can't trust photos from everyone who calls themselves official photojournalists. I've seen photos of the recent nazi rally in Orlando that were very slightly manipulated to darken the skin of participants to imply they were, in fact, "infiltrated BLM or Antifa". Anyone could use this system or a similar one - if the sensor signs the image with its private key anyone can trace a raw image to a specific sensor and, therefore, to a specific camera. If that image (or enough hash bits it becomes impractical to fake the data via collisions and still have a recognizable image) is placed on a public ledger, you can prove those pixels are yours and were taken at or before the moment in time they were added to the ledger. If the camera is part of a larger system, such as a phone, the software can add your own credentials to the raw image data, proving it was you who took the picture (unlocking the phone with, say, your face). I would not, however, want my personal family photos to be trackable like that. EU restrictions on images already took away a lot of my joy of photographing people.
