How Does It Work
How do Digital Signatures work?
The digital signature process used by Civil Twilight is powered by DocuSign.
DocuSign's patented process diverges from the cumbersome and potentially risky
PKI approach utilized by other digital signature providers. Signers using
DocuSign password-protect their access to the signing system, select a script
font with which to sign, and are assigned a unique alphanumeric identification
number that appears with their signature every time they sign.
Different levels of authentication are available, from simply using the
recipient's e-mail address, to a verbally-delivered access code, to a Fair
Issac authentication. In the Fair Issac authentication, a questionnaire is
generated based upon the last four digits of the signer's SSN, containing
detailed historical questions about the signer that must be answered correctly
in order to access the signing module.
An audit trail is maintained throughout the signing process for each document
that can be used subsequently to provide additional proof that the purported
signer actually executed the document. This audit trail differs greatly from
the paper world, where it is much easier for someone to assert that "it's not
my signature". In the world of digital signatures, if an audit trail ties the
signature to the signer's computer, the burden of proof has now effectively
been shifted back to the signer to prove that someone else had access to their
computer and signing password. Moreover, a true forgery in the digital world
will lack the appropriate audit trail and can be immediately identified as
