Hereinafter, an approval system and an approval method according to an embodiment of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a functional block diagram illustrating an example of an approval system 1 according to the first embodiment.
As shown in FIG. 1, the approval system 1 includes a work terminal 2, a business server 3, a mobile device 4, a mobile device 5, and an approval server 6. The work terminal 2, the business server 3, and the approval server 6 are connected to the network NW1. The mobile device 4 and the mobile device 5 are connected to the network NW1 via an IP (Internet Protocol) network, a mobile carrier network (wireless access network), and the like.

  The work terminal 2 is a client terminal for an operator to perform an operation (work) on a business server 3 having an IT (Information technology) system such as a financial system. The work terminal 2 includes, for example, an NW (network) communication unit 21, an input unit 22, a display unit 23, and a terminal control unit 24.

The NW communication unit 21 is connected to the network NW1 and communicates with the business server 3 via the network NW1.
The input unit 22 is an input device such as a keyboard and a mouse, for example, and receives an operation (work) for the business server 3 by an operation of the worker. For example, the input unit 22 receives a command when performing an operation on the business server 3.
The display unit 23 (an example of an output unit) is a liquid crystal display device, for example, and displays various types of information. The display unit 23 displays, for example, information such as a command received by the input unit 22, information indicating an approval result described later, and the like.

  The terminal control unit 24 is a processor including, for example, a CPU (Central Processing Unit) and controls the work terminal 2 in an integrated manner. For example, the terminal control unit 24 transmits an operation execution request received by the input unit 22 to the business server 3 via the NW communication unit 21. Further, the terminal control unit 24 causes the input unit 22 to display information (for example, an operation execution result) received from the business server 3 via the NW communication unit 21, for example.

  The business server 3 has, for example, an IT (Information Technology) system such as a financial system, and executes an operation (for example, a command) input to the terminal control unit 24 by an operator. When executing the operation, the business server 3 inquires of the approval server 6 whether or not the operation received from the work terminal 2 may be executed. In addition, the business server 3 executes the operation received from the work terminal 2 based on the approval result received from the approval server 6. The business server 3 includes, for example, an NW communication unit 31, an operator storage unit 32, and a work control unit 33.

The NW communication unit 31 is connected to the network NW1, and communicates with the work terminal 2 and the approval server 6 via the network NW1.
The worker storage unit 32 stores information regarding the worker. The worker storage unit 32 stores, for example, login information to the business server 3. For example, as illustrated in FIG. 2, the worker storage unit 32 stores “worker ID” and “password” in association with each other.

FIG. 2 is a diagram illustrating an example of data in the worker storage unit 32 in the present embodiment.
In FIG. 2, “worker ID” is an example of worker identification information for identifying a worker. The “worker ID” is used as a user ID when logging into the business server 3 from the work terminal 2. The “password” is a password used when logging into the business server 3 from the work terminal 2.
In the example illustrated in FIG. 2, “worker ID” is “abcde” for “password” for “W0001”. As described above, it is assumed that the “worker ID” and the “password” are registered (stored) in the worker storage unit 32 in advance.

  Returning to the description of FIG. 1, the work control unit 33 is a processor including a CPU, for example, and executes control related to operations. The work control unit 33, for example, according to whether the user ID (worker ID) and password transmitted from the work terminal 2 match the worker ID and password stored in the worker storage unit 32. The operator is allowed to log in to the business server 3 via the work terminal 2.

In addition, after logging in, the work control unit 33 transmits an approval request for requesting approval of execution of a command included in the operation to the approval server 6 in response to the operation execution request transmitted from the work terminal 2. In other words, the work control unit 33 transmits an approval request message including the worker ID and the command to the approval server 6 via the NW communication unit 31.
Further, the work control unit 33 executes the operation based on the approval result information indicating the approval result received from the approval server 6 via the NW communication unit 31. That is, the work control unit 33 executes the operation when the approval server 6 approves the approval request (permits the operation), and does not execute the operation when it does not approve (the operation is not permitted). The work control unit 33 transmits the operation execution result to the work terminal 2 via the NW communication unit 31.

The storage unit 62 stores information used for various processes executed by the approval server 6. The storage unit 62 includes, for example, a work authority storage unit 621, a work information storage unit 622, and a device information storage unit 623.

  The work authority storage unit 621 stores the worker ID, the confirmer ID, and authority information indicating authority to execute the work contents in association with each other. For example, as illustrated in FIG. 3, the work authority storage unit 621 stores “worker ID”, “confirmer ID”, “command type”, and “execution authority” in association with each other.

FIG. 3 is a diagram illustrating a data example of the work authority storage unit 621 in the present embodiment.
In this figure, “worker ID” is the same as in FIG. 2 described above, and “confirmer ID” is an example of confirmer identification information for identifying a confirmer. The “command type” indicates the type of command (for example, addition, deletion, update, etc.) that is the work content of the operation executed in the business server 3. Further, “execution authority” indicates whether or not the execution of the command indicated by “command type” is permitted, and is an example of the authority information described above.
In the example shown in FIG. 3, “Delete” of “Command Type” is “X” and “Execution Authority” is “×” for a pair of “Worker ID” “W0001” and “Confirmer ID” “C0001”. "Update" in "Command Type" indicates that "Execution Authority" is permitted.

  Returning to FIG. 1 again, the work information storage unit 622 stores at least a work ID and an expiration time in association with each other. Here, the work ID is, for example, a random value, and the expiration time indicates the time at which the execution of the work expires. The work ID and the expiration time are generated by an approval processing unit 631 described later. For example, as illustrated in FIG. 4, the work information storage unit 622 stores “command”, “work ID”, and “expiration time” in association with each other.

FIG. 4 is a diagram illustrating a data example of the work information storage unit 622 in the present embodiment.
In this figure, “command” is, for example, a command included in the approval request received from the business server 3, and “work ID” is an example of work identification information for identifying work content. “Expiration time” indicates the expiration time of approval for the “command” and “work ID”.
In the example illustrated in FIG. 4, “123456” is assigned as “Work ID” to “XXXX” as “Command”, and “Expiration Time” for “XXXX” and “123456” is “01:00:00”. It is shown that. In the example shown in FIG. 4, the time information of “hour”, “minute”, and “second” is applied as the “expiration time”, but “year” and “month” such as the year. Date information such as “day” may be included.

Returning to FIG. 1 again, the device information storage unit 623 stores the worker ID and identification information for identifying the portable device 4 of the worker in association with each other. That is, the device information storage unit 623 stores, for example, “worker ID” and “device ID” in association with each other as illustrated in FIG.
FIG. 5 is a diagram illustrating a data example of the device information storage unit 623 in the present embodiment.
In this figure, “device ID” is, for example, an IP address. When the user authentication unit 461 of the mobile device 4 (4a to 4d) determines that the user of the mobile device 4 is a valid worker, the “device ID” is transmitted to the approval server 6 (6a to 6c). Then, the “worker ID” and the “device ID” may be associated with each other and stored in the device information storage unit 623. Further, the “device ID” may be identification information that designates a transmission destination of a message to the mobile device 4 such as a MAC address (Media Access Control address) instead of the IP address.
In the example illustrated in FIG. 4, the “device ID” corresponding to the “worker ID” “W0001” is “XXX.XXX.XXX.XX1”.

  Returning to FIG. 1 again, the control unit 63 is a processor including, for example, a CPU and controls the approval server 6 in an integrated manner. For example, the control unit 63 executes an approval process for an approval request from the business server 3. For example, the control unit 63 includes an approval processing unit 631.

The approval processing unit 631 (an example of a processing unit) transmits the worker ID received from the business server 3 to the portable device 4 via the second wireless interface, and sets the worker ID to the worker ID via the second wireless interface. A corresponding confirmer ID is received. Specifically, the approval processing unit 631 receives an approval request message including the worker ID and the command from the business server 3 via the NW communication unit 61. The approval processing unit 631 generates the above-described work ID and invalidation time for the received command, and stores the command, the work ID, and the invalidation time in association with each other in the work information storage unit 622.
Further, the approval processing unit 631 transmits an inquiry message including the generated work ID and the worker ID received from the business server 3 to the portable device 4 via the network NW1 and the second wireless interface. And the approval process part 631 receives the message | telegram containing work ID, worker ID, confirmer ID, and distance information from the portable apparatus 5 via the network NW1 and a 2nd wireless interface.

  The approval processing unit 631 also checks the worker ID and confirmation stored in the work authority storage unit 621 when the distance measured by the portable device 5 is within a predetermined distance (for example, within 1 m (meters) to within 2 m).

[Fourth Embodiment]
Next, an approval system 1c and an approval method according to the fourth embodiment will be described with reference to the drawings.
As shown in FIG. 16, the approval system 1c according to the present embodiment includes a work terminal 2, a business server 3a, a portable device 4b, a portable device 5c, and an approval server 6b. In addition, since the functional block of each structure with which the approval system 1c is provided is the same as that of 1st Embodiment shown in FIG. 1, the description is abbreviate | omitted here. In the present embodiment, instead of executing the approval process for each command, the first embodiment is that the approval process is periodically executed every predetermined time, and the work ID and the expiration time are not controlled. Different from form.
For example, it is assumed that the approval server 6b in this embodiment does not include the work information storage unit 622.

FIG. 16 is a diagram for explaining an example of the operation of the approval system 1c in the present embodiment.
In this figure, the processing of step S41 and step S47 is the same as the processing of step S11 and step S17 shown in FIG.
In step S42, the business server 3a periodically transmits the worker ID.
Next, the approval server 6b transmits the worker ID received from the business server 3a to the portable device 4b (step S43).
The subsequent processing in step S44 and step S45 is the same as the processing in step S14 and step S15 shown in FIG. 6 except that the work ID is not included in the message. That is, the portable device 4b transmits a message including the worker ID to the portable device 5c (Step S44, the portable device 5c transmits a message including the worker ID, the confirmer ID, and the distance information to the approval server 6b. Send.

In step S46, the approval server 6b transmits, for example, approval result information including executable command information to the business server 3a. The business server 3a executes an operation (command) based on executable command information.
Note that the approval system 1c in the present embodiment periodically executes the processing from step S42 to step S46 at predetermined time intervals.

Next, the details of the approval process of the approval server 6b will be described with reference to FIG.
FIG. 17 is a flowchart showing an example of the operation of the approval server 6b in the present embodiment.
As shown in FIG. 17, the approval processing unit 631 of the approval server 6b determines whether or not there is a periodic approval request (step S801). The approval processing unit 631 determines whether or not the NW communication unit 61 has received a periodic approval request including the worker ID from the business server 3a. The approval process part 631 advances a process to step S802, when a regular approval request is received (step S801: YES). Further, the approval processing unit 631 advances the process to step S804 when the periodic approval request has not been received (step S801: NO).

  In step S802, the approval processing unit 631 acquires the worker ID. That is, the approval processing unit 631 acquires the worker ID received from the business server 3 by the NW communication unit 61.

  Next, the approval processing unit 631 transmits an inquiry message including the worker ID to the portable device 4b of the worker WK (step S803). The approval processing unit 631 transmits the inquiry message including the received worker ID to the portable device 4b via the NW communication unit 61 and the second wireless new interface, and the process proceeds to step S804.

  In step S804, the approval processing unit 631 determines whether there is a message from the portable device 5c. The approval processing unit 631 determines whether the NW communication unit 61 has received a message including the worker ID, the confirmer ID, and the distance information from the mobile device 5c. The approval process part 631 advances a process to step S805, when a message | telegram is received (step S804: YES). Moreover, the approval process part 631 returns a process to step S801, when the electronic message is not received (step S804: NO).

  In step S805, the approval processing unit 631 acquires the worker ID, the confirmer ID, and the distance information. That is, the approval processing unit 631 acquires the worker ID, the confirmer ID, and the distance information received from the portable device 5c by the NW communication unit 61 (receiving step).

  In step S806, the approval processing unit 631 determines whether the distance between the mobile device 4b and the mobile device 5c is within a predetermined distance. For example, the approval processing unit 631 determines whether or not the distance is within a predetermined distance based on the received distance information. When the distance is within the predetermined distance (step S806: YES), the approval processing unit 631 advances the process to step S807. If the distance is not within the predetermined distance (step S806: NO), the approval processing unit 631 advances the process to step S809.

  In step S807, the approval processing unit 631 determines whether or not there is an execution authority. The approval processing unit 631 acquires the execution authority corresponding to the worker ID and the confirmer ID received from the mobile device 5c from the work authority storage unit 621, and the acquired “execution authority” is “○”. It is determined whether or not there is. If there is an execution authority (there is a command type that becomes “◯”) (step S807: YES), the approval processing unit 631 proceeds to step S808. Further, the approval processing unit 631 advances to step S809 when there is no execution authority (there is no command type that becomes “◯”) (step S807: NO).

  In step S808, the approval processing unit 631 transmits approval result information including command information that permits execution. For example, the approval processing unit 631 extracts executable command information, and transmits approval result information including command information permitting execution to the business server 3a. After the process of step S808, the approval processing unit 631 returns the process to step S801.

  In step S809, the approval processing unit 631 transmits approval result information not permitting execution of the command to the business server 3a. After the process of step S809, the approval processing unit 631 returns the process to step S801.

As described above, in the approval system 1c in this embodiment, instead of executing the approval process for each command, the approval process is periodically executed at a predetermined time interval.
Even in this case, the approval system 1c and the approval method according to the present embodiment can suppress fraud and an operation error of the worker WK, as in the first embodiment. Moreover, since the approval system 1c and the approval method according to the present embodiment periodically execute the approval process, the load on the network NW1 and the process load on the approval processing unit 631 of the approval server 6b can be further reduced.

Moreover, in the approval system 1c in this embodiment, the approval server 6b does not include the work information storage unit 622, and the approval processing unit 631 does not generate the work ID and the expiration time.
Thereby, while simplifying the structure of the approval server 6b, the processing load of the approval process part 631 can be reduced.

In the above example, the business server 3a periodically sends an approval request to the approval server 6b. However, the business server 3a sends an approval request for each command to the approval server as in the first embodiment. 6b, and the approval server 6b may periodically execute the approval process at predetermined time intervals. In this case, the approval server 6b transmits the approval result information to the business server 3a without sending an inquiry message to the portable device 4b when the operation is permitted (approved) before a certain period of time. Also good.
In this case, similarly to the approval system 1c in the present embodiment described above, the load on the network NW1 and the processing load on the approval processing unit 631 of the approval server 6b can be further reduced.
