With secure access and transparent file details, you can add a new level of trust to signed files. This is well suited to manage access and credentials, like a drivers license.
Add a file containing a hash of a credential to the public. For example, a city office uploads a citizen's driver license.
The file has the keys of both the driver and the city official attached to it. Both must sign to create the file, but either can sign to delete the file; in this case if the license expires or has too many points.
Owners can optionally provide file details and prove the file existed at a point in time. This can be checked by insurance providers, employers, and more.
