Sort of. A camera with internet connectivity could automatically "notarize" photos. The signing authority would vouch that the photo (or other file) hasn't been altered since the moment of signing. It wouldn't be evidence that the photo was not manipulated before that moment.

That could make, EG, photos of a traffic accident good evidence in court. If there wasn't time to for manipulation, then the photos must be real. It wouldn't work for photos that could have been taken at any time.

You could upload a hash to the blockchain of a cryptocurrency for the same purpose. The integrity of the cryptocurrency would then vouch that the photo was unaltered since the upload. But that's not cost-effective. You could even upload the hash to Reddit, since it's not believable that they would manipulate timestamps to help some random guy somewhere in the world commit fraud.
