DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of an authentication system. In FIG. 1, in an ID authentication device 12, an authentication server 2 for authenticating ID data and a receiving device 4 for receiving authentication ID data are connected to a network 1 by a cable. A plurality of receiving devices 4 can be provided corresponding to the plurality of gates 6 of the building 5. The authentication server 2, the receiving device 4, and the gate 6 can be integrated and installed in the building 5. The receiving device 4 is wirelessly connected to the transmitting device 3 that transmits the authentication ID data.
[0010]
The transmission device 3 holds ID data 9 therein. It also has a wireless communication function and has an antenna 8. It also has a button 10 for starting transmission. The receiving device 4 also has an antenna 7, and the transmitting device 3 wirelessly communicates ID data with the receiving device 4 via these antennas 7 and 8. The authentication server 2 includes a registration ID database 11. In the registration ID database 11, ID data that matches the ID data held by the transmission device 3 is registered.
[0011]
In FIG. 1, the user goes to the gate 6 where the user wants to enter and leave the building 5 with the transmission device 3, and wirelessly transmits the authentication ID data to the reception device 4. The reach of radio waves transmitted from the transmission device 3 is limited by the power supply capacity of the transmission device 3 and is several meters. At this time, a transmission effective time zone is set for the transmission device 3, and the transmission device 3 does not perform transmission work when it is not the transmission effective time zone. When it is in the transmission effective time zone, the transmission device 3 performs transmission work. When the transmission start time 10 is pressed when the transmission effective time zone is not reached, the transmission device 3 performs transmission work. The authentication ID data received by the receiving device 4 is transmitted to the authentication server 2 via the network 1, and the authentication server 2 searches the registration ID database 11 and compares it with the corresponding registration ID data for authentication. The result is sent back to the receiving device 4 again via the network 1, and the receiving device 4 notifies the transmitting device 3 that the gate 6 can be opened when the authentication result is "match", When it is “mismatch”, this is notified to the transmission device 3.
[0012]
When the transmission apparatus 3 starts transmitting the authentication ID data by pressing the transmission start button 10 when it is not the effective transmission period of the authentication ID data, the transmission is continued for a certain period of time. If the authentication result is not received from the receiving device 4, the transmission is stopped, and if the authentication result is received, the transmitting device 3 records the time when the authentication result is received, and a certain time period from that time, or A fixed time zone before and after that time is newly set as a transmission effective time zone. Further, when a notification of the authentication result has not been received from the receiving device 4 once in a transmission effective time zone for a certain continuous day, the transmission effective time zone is canceled and set to a transmission invalid time zone.
[0013]
The transmitter 3 can be a small portable device with good portability, such as a wristwatch with a wireless communication function, a card with a wireless communication function, or the like. Further, a display function may be provided in the transmission device 3 to display that the transmission is valid when it is in the transmission effective time zone, and to indicate that the transmission is invalid when it is in the transmission invalid time zone. As ID data registered in the authentication server 2 and the transmission device 3, an ID unique to the user of the transmission device 3, such as a personal identification number, can be used. In the transmission effective time zone of the authentication ID data, the transmission device 3 simply transmits the authentication ID data every second, for example. On the other hand, transmission is not performed when it is not in the transmission effective time zone, and the transmission apparatus is in a dormant state, so that the power consumption is also in the lowest state.
[0014]
As described above, according to the present embodiment, since it is sufficient to consume power for transmission only during the transmission effective time zone, power consumption is reduced as a whole, and a battery having a small electric capacity can be used as a power source. Thus, it can be made smaller and more portable, or the battery life can be extended.
[0015]
Also, in this embodiment, when there is no authentication match for a certain consecutive day, the effective transmission time zone is canceled, so that the user's authentication system use time zone changes and the user is in a valid transmission effective time zone. Can be used when the authentication system is no longer used.
[0016]
Further, in this embodiment, even when the transmission is not valid, by pressing the transmission start button 10, the ID data transmission work can be started. It is possible to cope with the case where there is a time zone when the authentication system is used.
