INDIVIDUAL AUTHENTICATION METHOD

摘要

A safe and rapid individual authentication method using a mobile terminal. When an authentication is requested from a mobile terminal (30) to an authentication server (10), the authentication server (10) transmits a reference symbol for authentication to the mobile terminal (30). The mobile terminal (30) transmits the reference symbol to the authentication server (10) via a sale management server (23) via a reader (21) or the like and requests for authentication. The authentication server (10) compares the reference symbol with the reference symbol generated in advance and returns the comparison result and individual data required by the sale management server (23) to the sale management server (23).
