ABSTRACT:
In one embodiment, the present invention is a method and apparatus for adding signature information to electronic documents. One embodiment of the inventive method involves adding the signature information into a signature data field template corresponding to the electronic document, converting the signature data field template, including the added signature information, to an image file, and superimposing the image file over the electronic document to produce a signed electronic document. The inventive method substantially eliminates the potential for human error and security breaches in the signing of electronic documents.
