What is verifiable EXIF data? The submission was simulating a 100 year old photo. There could never be verifiable EXIF data for that. Sony didn't care; they liked the creativity.

Sony problem was in not catching someone who wanted to embarrass them. There's not a good way to detect that in advance.

The image was submitted digitally, so if it was originally antique, there would be a digitization stage, scanner or camera.

Sony makes cameras; signing the image in the exif with a public key would establish authenticity.

This event isn't likely to spur that change, but it may well come.
