ABSTRACT:
A method for determining whether a disputed electronic signature is that of a purported signator includes the steps of (a) creating in a single step an ink on paper signature and an identical electronic signature of the purported signator; (b) verifying that the ink on paper signature is consistent with known ink on paper signatures of the purported signator; and (c) comparing the disputed electronic signature with the electronic signature of the purported signator to determine whether the disputed electronic signature is that of the purported signator.
