According to the key management system of the present invention, even when the key management device is not connected to the network, the key management device is a key such as new information when the user's PIN is changed. The management registration information can be updated from the key management device, and the key management device temporarily stores the key management registration information updated at that time.
Thereafter, when the key management apparatus is connected to the network, the updated key management registration information stored in the key management apparatus is transmitted to the key management server, and the key management registration information is the key management server. In the case where there are a plurality of key management devices, the key management registration information is transmitted from the key management server to another key management device other than the transmission source via the network. Even if the device is of the portable (portable) type, the key management registration information can be updated immediately. That is, the portable key management device may be in an environment in which network connection can not be made at the transfer destination, but even in such a situation, the key management registration information can be updated at any time.
Therefore, it is not necessary to connect the key management device to the key management server in real time via the network, and only if the user who has the authority to register and change the key management registration information on the key management device side needs to change the setting in real time. It is easy to use and has excellent security.
Also, for example, when an expiration date is set for the user's PIN code, the key management device and the key management server can not connect to the network, so that the PIN code can not be changed, and the key can be extracted. It is possible to solve the conventional problem of becoming a situation where there is no

  Note that if there is only one key management device, the updated key management registration information can not be transmitted to other key management devices, but the key management device or another management device can be network-connected later. In this case, the updated key management registration information can be shared, which is useful.

Further, according to the present invention, when not connected to the network, if there is the updated key management registration information and the information is not transmitted to the key management server, it is urged to connect to the network. Are automatically displayed by displaying a message on the display unit provided in the key management device, for example, a liquid crystal touch panel provided on the surface of the key management device, or turning on or flashing the status display LED. This prevents the key management registration information, which has already been updated for a long time, from being transmitted to the key management server.
According to this, in the key management device, the storage amount for storing the history information consisting of the update contents of the key management registration information and the update date is limited, and when the capacity is exceeded, the oldest information is overwritten and deleted. Although there is a possibility that history information may not be transmitted to the key management server, it is possible to prevent human error by providing a display prompting transmission.

  Further, according to the present invention, the key management server manages the updated key management registration information, and another management apparatus having a communication specification different from that of the key management apparatus, for example, an entry / exit management apparatus for managing entry / exit The storage management device for storing and managing documents and packages is transmitted via the network according to the communication specification corresponding to them. Therefore, key management registration information updated between the devices due to the difference in the characteristics of each management device Can not be transmitted via the network, and information can be reliably shared among management devices.

  Further, according to the present invention, another terminal device such as a personal computer separate from the key management device transmits the key management registration information updated by the key management device to the key management server via the network. Since the key management device is not provided with the network connection function, the key management registration information can be updated using another terminal device such as a personal computer which is usually used.

Further, according to the present invention, when the key management registration information is user information such as a personal identification number, the key management server has a server storage device for storing the update date and time corresponding to each user information. Comparing the stored update date corresponding to the user acquired by the updated user information (example of key management registration information) transmitted from the key management apparatus with the update date transmitted from the key management apparatus; The updated user information (example of updated key management registration information) is sent to other key management devices via the network only when the update date is later than the storage update date, so it is always the latest User information (example of key management registration information) is obtained, and this information is transmitted to another key management apparatus.
Therefore, for example, before the key management device is connected to the network, there is a possibility that the password number (an example of the user information) of the same user may be changed from another key management device, in which case the key management device There is also a problem that the latest PIN code is overwritten with the old one depending on the timing of connection to the network, but in the present invention, the key management server transmits the latest PIN code (an example of user information) There is no such problem because it is supposed to be

  As in the key management system of the present invention, the point that the key management registration information can be updated anytime for a key management device not connected to the network is completely described in the above-mentioned Patent Document 1. Absent.

Then, when there is a request from the key management server 50 (403), the information related to the history information, that is, the updated user information is transmitted to the key management server 50 if the user information is updated. (404). Here, the user whose user information has been updated and the updated PIN code of the user are read from the user information storage area 37a, and the update date and time at that time are read from the history information storage area 37c, These pieces of information are sent together with the history information.
If the user information is not updated, the history when the device information is updated, the usage history of the key management device 30, the history of error information generated in the key management, etc. are transmitted.
In addition, if the request from the key management server 50 is not for a predetermined time t, the processing is ended.

(Control in key management server 50)
In the control device 51 of the key management server 50, processing content as shown in FIG. 7 is executed.
When the control device 51 receives a signal from the key management device 30 connected to the network 100 (501), the control device 51 determines whether or not there is unreceived history information (502), and if there is unreceived history information A signal requesting information is transmitted to the key management device 30 (503).

Then, when there is a signal from the key management device 30, it is received and stored (504, 505, 506).
Next, the control device 51 determines whether or not there is updated user information in the received information (507), and if there is updated user information, the updated user information And store the history information (508). The history information at this time includes the update date (X) when the user information is updated.

  Next, the control device 51 sends the corresponding user (sent from the key management device 30) based on information related to all users who use the present system, as shown in FIG. 8, which are stored in advance in the server storage device 54. The information on the user who has input information to the key management device 30 is read out (509). Here, the registration number and the name of the corresponding user, and the latest date and time when the personal identification number related to the user is updated (the date and time of the first registration if not particularly updated) (Z) are read.

Then, the control device 51 compares the update date (X) transmitted from the key management device 30 with the stored update date (Z) stored in advance in the server storage device 54 (510). The information on the corresponding user in the server storage device 54 is updated and stored only when the update date (X) transmitted from the server is newer than the stored update date (Z) stored (511, 512). This will always provide the latest registration update information.
Here, the password of the user who has input the update information is updated to a new password, and the update date (X) is updated as the storage update date (Z) and stored in the server storage device 54. In addition, the usage history of the key management device 30 transmitted is also stored.
In addition, in order to determine the presence or absence of transmission to the other key management devices 10 and 20 from the comparison of the update date and time generated by the key management device 30 and the storage update date and time stored by the key management server 50 It is necessary to perform time synchronization of the respective management devices 10 to 12, 20, 30 including the key management server 50 of FIG. As a method of time synchronization, when each management device 10-12, 20, 30 is in a state of being connected to the network, each time information managed by the computer of the key management server 50 is at regular intervals such as once every hour in the system.

There is also a method in which a time delivery server is disposed on the network 100, and each device in the system is synchronized at that time.

  Next, the control device 51 updates the key management registration information of the updated key management device 30, in this case the password of the corresponding user, to a key management device other than the key management device 30 of the transmission source, here Distributed to the key management device 10 of the branch A and the key management device 20 of the branch B (513), and other management devices other than the key management device, in this case, the storage management device 11 and the entry / exit management device 12 of the branch A It distributes in the state corresponding to those communication specifications (514), and shares information.

  After the information sharing is executed, the user who has been updated to a new password is a new key management device 10 other than the key management device 30, the key management device 20, the storage management device 11, and the room access management device 12 the new one. A PIN can be used.

The control device 51 compares the transmitted update date (X) with the stored update date (Z) stored in advance in the server storage device 54 (510), and the transmitted update date (X) If it is older than the stored update date and time (Z), information on the corresponding user in the server storage device 54 is sent to the key management device 30 that has sent the updated key management registration information. It can also be done. According to this, in the key management device 30, the latest registration update information is always obtained by storing the latest registration update information.
Further, the control device 51 is a management device other than the key management device, in this case from the storage management device 11 and the room access management device 12 of the branch A, in a state corresponding to the communication specifications thereof You can also receive updated user information for

According to the key management system configured and controlled as described above, even when the key management device 30 is not connected to the network 100, the key management device 30 changes the PIN of the user. The new password can be updated from the key management device 30, and the key management device 30 temporarily stores the updated new password of the user at that time along with the update date and time.
Thereafter, when the key management device 30 is connected to the network 100, the new password of the updated user stored in the key management device 30 is sent to the key management server 50, and the key management server 50 Since the key management device 30 other than the transmission source key management device 30 is transmitted via the network 100 to the key management device 30, it can always update the user's PIN code for the key management device 30 that can not be connected to the network 100 by carrying. can do.
