some ideas from Corona Virus "Stay at Home" order

[Bob Rasmussen]

Insurance photos is something I have thought about. Maybe for damage to a 
car.  Maybe before and after photos. Meaning you might need to verify 
geolocation and also date/time the photo was taken. Maybe even the 
direction the camera was pointing.

To "harden" the proof, you could embed the JPG photo (containing the 
GEOTAG, etc.) inside a PDF, which can then be certified (tied to a 
certificated individidual, tied to a validated date/time clock, 
encrypted, and password protected. When a certificate is applied to a PDF, 
that process hashes the entire PDF, so that contents within can not be 
changed. I think this could prove when and where the the picture was 
taken. I'm not sure what the mechanism could be for validating the 
date/time clock.
