PURPOSE: A system authenticating an originality of a trade secret and a method thereof with reinforced security and selectivity are provided to encrypt content of an original document and request electronic fingerprints from a user's computer, thereby reducing inhibition about transmitting the user's trade secrets. CONSTITUTION: A user originality authentication agent program transmitter(1100) transmits an originality authentication agent program to a user's computer. A generated electronic fingerprint receiver(1220) receives electronic fingerprints about a digital file from the user's computer for an originality authentication service. An authentication requester(1240) transmits the electronic fingerprints to a certificate authority. An authentication result receiver(1250) receives electronic authentication information from the certificate authority. An originality authentication generator(1260) generates originality authentication information and an originality authentication certificate using the electronic authentication information.
