Authentication is performed by confirming that the true operator presents his/her own biometric authentication information at a common portable information terminal. The biometric authentication system has an image capture unit that acquires first and second image data of different biometric areas of an operator during a predetermined period, a display that displays a guide to guide the operator to the location of the biometric area in order to capture different biometric areas of the operator, and a memory that stores biometric authentication information of the operator in advance. Furthermore, the first vital information and the second vital information are extracted from the image data of the different biometric areas, respectively, the identity of the operator is determined based on the first vital information and the second vital information, and if the identity of the operator is confirmed, the biometric authentication is performed.
