摘要： 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.

摘要： The present invention achieves high-accuracy multimodal biometric authentication of a plurality of body organisms while suppressing postural fluctuation when the plurality of body organisms are captured and suppressing the computational complexity of processing a plurality of biometric features. According to the present invention, an authentication system includes a storage device that stores feature quantities for a plurality of body organisms in association with users, a capture device that photographs body organisms, and an authentication processing device that performs biometric authentication on the basis of images inputted from the capture device. The capture device photographs a first body organism of a first user during a first period and captures a second body organism and a third body organism of the first user during a second period that is different from the first period. The authentication processing device calculates a first feature quantity from the first body part photographed during the first period, respectively calculates a second feature quantity and a third feature quantity from the second body organism and the third body organism captured during the second period and compares with the feature quantities for the body organisms of each user stored at the storage device.
