Further, an IC card for personal authentication and identification is distributed to each client. Also, each client machine 10 has a card reader / card for performing the authentication / identification processing of the user while being present on an IC card basis.
A writer is equipped.

An IC card is a storage medium that carries an employee ID and a password of a user who holds the card. For example, it is preferable that the employee ID is recorded in the read-only area of the IC card and the password is recorded in the readable / writable area, thereby permitting the change of the password while prohibiting the diversion of the IC card.

The IC card and the card reader / writer are
For example, the reading / writing operation may be performed by a non-contact method such as an electromagnetic transfer method. Of course, the reading / writing operation may be performed by a contact method such as magnetic recording, or the employee ID and the password may be input based on the user console without using a card. .

The client machine 10 is constituted by a general computer system such as a personal computer (PC). On the display screen of the client machine 10, an organization (or a specific workplace that is a part of the organization) is displayed.
A seat browser for displaying the state of the entire seat, and an indicator that allows the client user himself to input a destination when the user leaves the console are arranged.

FIG. 2 shows a display example of the seat browser displayed on the primary screen of each client machine 10. As shown in the figure, the seat browser is composed of a spreadsheet that lists the status of each employee's presence / absence and the destination when leaving. Each client
The user can check the presence / absence status of another employee on the screen of the host terminal 10 assigned to him / her.

FIG. 3 shows a display example of a destination indicator on each client machine 10 for the user to input a destination to the console when the user leaves the desk. As shown in the figure, "On Seat", "Off"
There are a number of radio buttons, such as "Seat", "Meeting", and "Out of Office", indicating the presence status and the standard destination when leaving, and the user can use his / her mouse to operate his / her own radio button. Alternatively, the user can input the location, or if the user skips the input of the destination indicator when leaving the seat due to forgetfulness or the like, a standard destination may be set.

On each client machine 10, an IC

1 is interconnected with other devices (to be described later) by a bus 508.

The memory 502 is a storage device used to store a program code to be executed by the CPU 501 and temporarily store work data being executed. It should be understood that the memory 502 shown in the figure includes both non-volatile and volatile memories.

The display controller 503 uses C
This is a dedicated controller for actually processing a drawing command issued by the PU 501. The drawing data processed by the display controller 503 is once written in, for example, a frame buffer (not shown), and then output to the screen by the display 511.

The input device interface 504 is a device for connecting user input devices such as a keyboard 512 and a mouse 513 to the computer system 500. For example, through a screen of the display 511, a GUI (Graphi
A cal User Interface (CUI) environment is provided so that the user can enter user commands into the system 500 in a visual and intuitive manner based on the operation of the mouse 513.

Network interface 505
Uses a LAN (Local Area Network) according to a predetermined communication protocol such as Ethernet.
Connect to a local network such as The local network is attached to a predetermined office or a premises owned by a company or other organization. Of course, the local network can be connected to a wide area network such as the Internet by a router (not shown).

On the network, between each client machine 10 and the presence status collection server 50, the employee ID and the password read by the card reader / writer are transmitted, and the presence information on all the client machines is transmitted. Data transfer such as distribution is performed. Of course, other data and programs may be distributed via a network. For example, a client application or a server application for implementing the present invention may be distributed via a network.

The external device interface 507 is a device for connecting an external device such as a hard disk drive (HDD) 514 or a media drive 515 to the system 500.

The HDD 514 is an external storage device on which a magnetic disk as a storage carrier is fixedly mounted (well-known), and is superior to other external storage devices in terms of storage capacity and data transfer speed. Placing a software program on the HDD 514 in an executable state is referred to as “installing” the program in the system. Usually HD
D514 stores, in a nonvolatile manner, an operating system program code to be executed by the CPU 501, an application program, a device driver, and the like.

For example, a client application or a server application for realizing the present invention can be installed on the HDD 514.
Further, data such as presence information received via the network can be stored on the HDD 514.

Used for the purpose. For example, a client application or a server application for realizing the present invention can be physically distributed and distributed between a plurality of devices using these portable media.

Next, a card registration process performed on the presence status collection server 50 will be described.

The card distributed to each employee is applied to the use of countermeasures for leaving the seat by utilizing the personal authentication / identification processing of the employee. Cards are more preferred. The employee ID is recorded in the read-only area, and the password is recorded in the read / write function area (described above). Each client machine 10 provides a service for reading out an employee ID and a password from an IC card of a user who attempts to access the machine via a card reader / writer provided.

The read employee ID and password are
The card is transferred to the presence status collection server 50 via the network, and the card is registered. “Registration” referred to here is to associate a client machine 10 to which a card reader / writer is connected with an employee ID (that is, a specific client user).

FIG. 5 is a flowchart showing a card registration process according to this embodiment. The processing is
In practice, this is realized by executing a predetermined program code on the presence status collection server 50.

When the presence status collection server 50 receives a new employee ID from a specific client machine 10 via a network, the presence status collection server 50 transmits the new employee ID to the client machine 10 (or a card mounted on the client machine 10). The registration is made in association with the seat number corresponding to the reader / writer (step S1).

When the client user leaves the registered seat, the default seat status is registered (step S2).

The registered contents such as the correspondence between the client machine 10 and the employee ID are stored, for example, on the local database 51 of the presence status collection server 50. In addition, the presence status collection server 50 can recognize the registered employee ID and password at the time of presence or absence of a person based on such registration information.

FIG. 6 is a flowchart showing a procedure performed in the security system 1 when an employee first sits on the client machine 10 assigned to him / her. The process at the time of sitting is actually realized by a cooperative operation between the client machine 10 and the presence status collection server 50 via the network. Hereinafter, a processing procedure executed at the time of sitting will be described according to this flowchart.

When the power of the client machine 10 for the employee is turned on, the seat browser is automatically started (step S11).

An employee inserts his card into a card reader /
When placed on the writer (or when the card is placed in a readable state) (step S12), the employee ID and password are read from the card.

Then, the client machine 10 adds its own seat number to the read employee ID and password, and transmits it to the presence status collection server 50 (step S13).

The presence status collection server 50 searches the local database based on the seat number, extracts the seat, ie, the employee ID and password of the employee registered as a user of the client machine 10, and Employee ID received from client machine 10
And password (steps S14 and S1).
5).

If the seat number, the employee ID, and the password match, the seat, ie, the client
It can be determined that the user registered in the machine 10 is seated. In this case, the presence status collection server 50
Switches the presence information of the corresponding record in the presence status database from "off" to "on" (step S1).
6).

On the other hand, if at least one of the seat number, the employee ID, and the password do not match, it can be determined that a person other than the registered user has seated on the seat. In this case, assuming that the user authentication process has failed,
The seat browser is closed (step S17). And
The process returns to step S11, and waits until the next employee logs in.

In the security system 1, the status of the presence / absence of an employee at each client machine 10 is constantly monitored. FIGS. 7 to 9 show, in the form of flowcharts, processing procedures performed in the security system 1 after an employee, that is, the user himself or herself, sits on the client machine 10. This processing procedure is actually realized by the client machine 10 and the presence status collection server 50 performing a cooperative operation via a network. Hereinafter, a processing procedure for monitoring the presence / absence state of an employee will be described with reference to the flowcharts of the respective drawings.

The presence status collection server 50 periodically executes a card presence confirmation (Request Response) command via the network (for example, sends a card presence confirmation command all at once) (step S21), and each client The presence information of each user is periodically updated by confirming the presence of the card on the machine 10 (step S22).

In step S23, the client
The presence of the card on the machine 10 is confirmed. When it is determined that the card does not exist and the client machine 10 is away from the desk, the presence status on the client machine 10 is switched from "on" to "off" (step S31). Then, the transmission of information from the client machine 10 to the presence status collection server 50 and the operation on the client machine 10 are locked (input / output prohibited) (step S32).

On the other hand, when it is determined that a card is present on the client machine 10, the presence status collection server 50 sends the card to the client machine 10 in accordance with the input contents of the destination indicator on the client machine 10. Update your presence status above.

That is, the client machine 10
Is changed according to the display of the destination indicator entered on the client machine 10 (step S41), and the employee ID, password, and seat number on the client machine 10 are collected. The data is transmitted to the server 50 (step S42).

The presence status collection server 50 searches the local database based on the seat number, extracts the seat, ie, the employee ID and password of the employee registered as a user of the client machine 10, and Employee ID received from client machine 10
And password (steps S43 and S4).
4).

If the seat number, the employee ID, and the password match, that is, if the user authentication is successful, the presence status is changed from “ON” to the requested status on the presence status collection server 50. Yes (Step S4
5). Then, the operation on the client machine 10 is locked (input / output prohibited) (step S46).

On the other hand, if at least one of the seat number, the employee ID, and the password does not match, that is, if the user authentication fails, the process returns to step S21 without changing the seating status, and A process such as periodically issuing a card presence confirmation command and periodically updating the presence status is repeatedly executed.

FIG. 10 is a flowchart showing a processing procedure performed in the security system 1 when an employee who is away from the desk, ie, the user himself or herself, is seated on the client machine 10 again. This processing procedure is actually realized by the client machine 10 and the presence status collection server 50 performing a cooperative operation via a network. Hereinafter, the processing procedure when the employee is seated will be described with reference to the flowcharts of the respective drawings.

An employee inserts his card into a card reader /
When placed on the writer (or when the card is placed in a readable state) (step S51), the employee ID and password are read from the card.

Then, the client machine 10 adds the own seat number to the read employee ID and password, and transmits the result to the presence status collection server 50 (step S52).

The presence status collection server 50 searches the local database based on the seat number, extracts the seat, ie, the employee ID and password of the employee registered as a user of the client machine 10, and Employee ID received from client machine 10
And password (steps S53 and S5).
4).

If the seat number, the employee ID, and the password match, the seat, that is, the client
It can be determined that the user registered in the machine 10 is seated. In this case, the presence status collection server 50
Switches the presence information of the corresponding record in the presence status database from “off” to “on” and unlocks the client machine 10 that is locked (input / output prohibited) (step S55). As a result, the seated user himself or herself
Can resume daily operations (step S5)
6).

On the other hand, when at least one of the seat number, the employee ID, and the password do not match, it can be determined that a person other than the registered user has sat on the seat. In this case, assuming that the user authentication process has failed,
The operation lock state of the client machine 10 is maintained. Then, the process returns to step S51. <Wait until the employee logs in next time.

The password on the card can be rewritten by the user himself / herself, so that the reliability of the security system 1 can be prevented from being impaired by the regular password exchange.

For example, a card reader / writer and management software connected to the presence status collection server 50 may be used. Place the card on the reader / writer (or place the card in a readable location) and enter the old and new passwords. Provided that the old password is the same as the password on the card, the new password is written on the card and is also encrypted and transferred to the presence status collection server 50 and written on its local database.
