ABSTRACT:
Using know methods a digital signature, such as a one-way hash, of a document is produced. A digital representation of a signature is associated with the digital signature. The digital representation may be, for example, a digitized picture of the signature. Both the digital signature and the digital representation of the signature are sent to a recipient. The recipient may then view the digital representation of the signature and provide visual confirmation of the authenticity of the signature. In addition, the digital representation of the signature may be electronically analyzed to determine a match. The digital representation of the signature may then be shown to the recipient when the electronic analysis indicates an authentically signed document so as to provide a visual assurance of integrity.
