US Patent 7529934 Individual certification method

The present invention provides a safe and quick individual authentication method using a mobile terminal. When authentication is demanded from a mobile terminal 30 to an authentication server 10, the authentication server 10 transmits verification code for authentication to the mobile terminal 30. The mobile terminal 30 returns the verification code through a sales management server 23 via a reader 21 or the like to the authentication server 10 for authentication. The authentication server 10 verifies the returned verification code to the verification code previously generated, and returns a result of the verification and personal data required by the sales management server 23 to the sales management server 23.
