PROBLEM TO BE SOLVED: To enable a registrant to constantly and easily provide many referrers with the latest pieces of private information. SOLUTION: Since identification information, a reference password and an updated password are provided to the registrant to perform data registration of the private information in a host processor, the referrers can refer to the private information from a reference user terminal 13 with the identification information and the reference password provided from the registrant and the registrant can update the data of the private information to the latest contents from a registration user terminal 12 with the identification information and the updated password.
