Transmission terminal, transmission system and recording medium

摘要

A transmission terminal includes an authentication unit that determines, when the transmission terminal is not connected to a network, whether authentication of a storage medium is confirmed based on authentication information stored in a storage unit and authentication information read from the storage medium, and transmits, when the transmission terminal is connected to the network, an authentication request containing the authentication information read from the storage medium to an authentication device connected to the network, and a maintenance unit that alters maintenance functions executable on the transmission terminal based on whether authentication of the storage medium is confirmed based on the authentication information stored in the storage unit or a notice indicating that authentication of the storage medium is confirmed is received from the authentication device.

主权项

1. A transmission terminal, comprising:
a detachable-storage interface to which a first storage is detachably attached, the first storage storing first information; a second storage configured to store second information; and circuitry configured to
determine whether the transmission terminal is connected to a network;determine, when the transmission terminal is not connected to the network, whether an offline maintenance process is authorized according to the second information stored in the second storage and the first information read from the first storage;maintain performance of the transmission terminal, when the offline maintenance process is determined to be authorized, by utilizing the offline maintenance process according to first instructions stored in the second storage;transmit, when the transmission terminal is connected to the network, an authentication request to an authentication device connected to the network;receive an authentication message from the authentication device in response to the transmitted authentication request;maintain performance of the transmission terminal, when the authentication message indicates that an online maintenance process is authorized, by utilizing the online maintenance process according to second instructions received from the authentication device;perform a videoconference process when the offline maintenance process is determined to be not authorized; andperform the videoconference process when the authentication message indicates that an online maintenance process is not authorized.
