The IAU 1 is constituted of a fingerprint identification part 1 a and an IC card part 1 b.
The write system 2 is constituted of an application (APL) 21 for connecting the system 2 to the server 4 to obtain data or a program to be written into a rented area or areas, and a write application (write API) 22 for delivering various data to the IAU 1. The various data include information on the presence or absence of authentication as defined for each contract, an access file number (file No.), an access key (write key), and write data.
The fingerprint identification control part 12 receives a fingerprint identification instruction from the common control part 11, accesses the FACCT 13 to obtain an encrypted key for opening a fingerprint template file in the IC card part 1 b, and outputs the encrypted key to the IC card part 1 b.
Upon receipt of the fingerprint template data from the IC card part 1 b, the fingerprint identification control part 12 expands the data in the work RAM to compare the data with fingerprint data inputted from the fingerprint sensor 14. Then the fingerprint identification control part 12 outputs the comparison result to the common control part 11.
The IC card part 1 b is connected to the common control part 11 through a serial interface, and the common control part 11 serves as a card reader for the IC card part 1 b.
The structure of the IC card part 1 b is the same as a general IC card. In the structure, an internal IC card CPU divides a memory into designated structural blocks so that the memory will be managed on a block basis. An individual key (access password) can be set for each block, and any access key such as read, write, or delete key can also be set.
In FIG. 1, EF 4 corresponds to a rented memory area 16 a.
The fingerprint template file holds one or more fingerprint data on an authorized user or users. The fingerprint template is opened by the key decrypted in the MF 15 so that the fingerprint data will be outputted.
an authentication unit having an IC card part for storing plural files and a fingerprint identification part with a fingerprint sensor, the fingerprint identification part allowing access to a specific file of the IC card part when fingerprint identification is authenticated;
a terminal application for outputting to said authentication unit the file number and the information for accessing the file to read the contents written in the file so as to start a specific application, wherein
