A renewal apparatus for a portable storage device, such as an IC card, holding biometric data of an individual, avoids divulging biometric data during renewal, while rigorously confirming the identity of the individual. A control unit (22) confirms the identify of the individual in biometric authentication by the biometric authentication functions of an old IC card (5). and confirmation of the identity of the individual is performed rigorously using the IC card with biometric authentication functions. If confirmation of the identity of the individual is satisfactory, the biometric data obtained in the biometric authentication is registered in a new IC card (5-1). The renewal can be performed with only a single image capture operation, and divulgence of biometric information is prevented.
