Abstract
Systems and methods for digitally certified stationery are described. In one aspect, a stationery granting authority (SGA) receives a request from a user to generate a document. If the user is authorized for the requested document, the SGA generates a certificate with credentialing information from data in the request. The SGA generates a first digital signature from some of the credentialing information. The SGA communicates the certificate to the user for editing and distribution as the document. A recipient of the document determines whether the document is “official” by contacting a specified service to provide certain information from the document. The verification service computes a second digital signature from the provided information for comparison to the first digital signature. If there is a match, the service notifies the recipient that the document is valid/official. Otherwise, the recipient is notified that the document is not valid.
