A biometrics authentication system that performs individual authentication in use of biometrics information facilitates authentication operation and reduces authentication errors. A storage unit stores therein the shape of the body part of the user, of which is captured at the time of registration of biometrics data, and a display unit displays the body part shape from the time of registration when authenticating the user for directly identifying the state of image capture of the body part at the time of registration and for guiding into a state of image capture of the body part similar to the state at the time of registration. The body part can be guided effectively such that the circumstances of body part image capture at the time of authentication and at the time of registration are in agreement, for improved verification efficiency.
