Abstract
In this invention, a member generates unique information of an electronic file to be notarized by using a member terminal. Upon identifying the member by signature input, a notary server stores the unique information and the identification information of the member in a database, together with a registration key, in correspondence with each other, and transmits the registration key ID to the member. When a general user wants to check notarization of the electronic file, he/she uses a general user terminal to generate unique information by using the electronic file, and transmits it to the notary server, together with the electronic file and acquired registration key ID. The notary server transmits notary information to the general user if the received unique information coincides with the unique information in the database.
