How does Entropia Internet Notary Service differ from a Notary Public?
Aside from the signature being digitally applied, this service serves solely to witness the existence of a specific electronic file at a specific point in time, and so long as you keep your secret information undisclosed to others, it can be demonstrated that it was you who notarized the file. If you digitally sign your file using your own secret keys before having it notarized, this would be considered legally binding under some pending legislative bills.
