Semiconductor element, biometric authentication method, biometric authentication system and mobile terminal

摘要

A semiconductor element (110) or mobile terminal stores a user's biometric information pattern (134) used for execution of a biometric authentication process and the residual number of trials (136) indicating the number of allowed failures in the biometric authentication process, sends processing data to an external device (200) so that the external device (200) can use the processing data when the external device (200) executes part of the biometric authentication process, and decreases the residual number of trials (136) by a predetermined value while the processing data is output to the external device (200) after start of communication with the external device (200).
