It is determined whether or not a portable memory ID and password are input (S12). If there is an input, the received portable memory ID and password are temporarily stored (S13) (S14).

The portable memory ID may or may not be valid. Compare the stored information with the current password and check whether the password rule is satisfied by the information length, etc. (S15), and if the mobile memory ID and password are the same as the current one, registration is not renewed and the terminal responds normally Notify and exit.
If it is determined in step S15 that the check is not the same and the password is appropriate, it is determined whether there is an abnormality (S16). If there is no abnormality, the new password is registered and updated (S17), and a normal response is notified to the terminal 6 (S18). ,finish. If the stored password is invalid, registration is not updated and an abnormal response is notified and the process ends.

FIG. 4 is a flowchart for explaining the operation of the third embodiment of the portable memory connection use authentication system according to the present invention.
FIG. 4 shows a processing flow on the terminal side when using a password (that is, during authentication). Also at this time, when registering the password, the terminal and the portable memory are connected and processing is performed while communicating with each other.
There are cases where you want to create multiple terminals that do not require password entry. In the portable memory connection use authentication system of the third embodiment, in this case, when the same password as the password already registered in the portable memory 1 (FIG. 1) is re-registered, as in the first embodiment. The same contents are registered in the terminal 6 (FIG. 1), and thereafter used when the portable memory 1 is connected.

Referring to FIGS. 1 and 4, terminal 6 does not perform this process unless automatic authentication is permitted. It is determined whether or not automatic authentication is to be started (S21). When automatic authentication is to be performed, the start is declared in the portable memory 1 (S22), and a memory ID is requested and received (S23) (S24).
Whether there is a password corresponding to the memory ID is searched (S25), if it exists, it is transmitted (S26), and authentication is performed (if the memory ID is empty, password transmission is repeated). If not, exit.

FIG. 5 is a flowchart for explaining the operation of the fourth embodiment of the portable memory connection use authentication system according to the present invention. FIG. 5 shows a processing flow on the portable memory side when using a password (that is, during authentication). Also at this time, when registering the password, the terminal and the portable memory are connected and processing is performed while communicating with each other.
In a mobile memory connection use authentication system, there is a possibility that a different mobile memory may be attached or detached on the terminal side at any time, and there is a possibility that the number of passwords to be held increases. Is too inefficient.
Therefore, in the fourth embodiment, the portable memory side has a function of registering a unique ID that is paired with a password, and the terminal has a means for confirming this unique ID with the portable memory side when the memory is mounted.
