Description

  The present invention relates to an attendance management system for appropriately managing attendance and work man-hours at a dispatch destination in, for example, a small-scale company or office having many stores, or a dispatch company that dispatches dispatched employees. More specifically, the present invention relates to a dispatch work management system having a function of preventing fraud such as falsification of the result of dispatch work.

  In recent years, the proportion of elderly people has been increasing in Japan, and care for elderly people such as bedridden and dementia has become a serious problem.

  In general, care for elderly people who are bedridden or demented is in a state in which the caregiver becomes ill or mentally unstable due to the strict work content, lengthening, aging of the family being cared for, etc. There are many cases that fall. In addition, nursing care requires a certain level of specialized knowledge, and it is actually difficult to provide sufficient care with family care. Against this background, a care service business in which temporary staff with knowledge related to care specializes in elderly care is attracting attention.

  In a business mode in which temporary staff (visiting caregivers) who belong to a nursing care facility visit the home of the care recipient and provide care services, the temporary staff goes directly to the care recipient. In many cases, they go home without going to their offices even when they leave the office. In such a business form, temporary staff attendance and attendance management is conducted by a caregiver dispatched from a nursing care office, receiving a working time approval stamp from the care recipient, recording the time on a paper, and submitting it to the affiliated office at a later date. The method was general.

  However, with this conventional method, the caregiver can correct or falsify the time after receiving the approval stamp from the care recipient, and the office cannot be managed accurately, so the caregiver cannot manage the time. There was a problem between the subject and the business. In addition, there are cases in which the status of attendance and work is ascertained only by self-reporting by the temporary staff, but there are problems that it takes time to confirm work and paperwork, and it is difficult and inaccurate to grasp actual working hours. .

  Therefore, as can be seen in Patent Document 1, a time management method and a time management system have been developed that enable accurate management of temporary staff attendance. The operation and effect of the method and system described in Patent Document 1 are as follows.

(1) At the dispatch destination, the stamp data generation terminal installed at the dispatch destination is connected to the mobile phone owned by the worker, and the attendance information is sent to the host computer via the network by e-mail. Send.
(2) The identification data indicating the work location is set in advance in the terminal for generating stamped data, and the data input outside the work location can be prevented by transmitting it together with the attendance information.
(3) Since the time of the time stamp uses the clock of the time stamp data generation terminal, the worker cannot set false time data. It is also possible to check the history of time data corrected by operating the time stamp data generation terminal by sending it to the host computer.
(4) Since the attendance information is encrypted and transmitted by the terminal for generating stamped data, data alteration can be prevented.
(5) Can be engraved with simple operation by personal authentication using the mobile phone number. In addition, since mobile phones cannot be easily lent or borrowed, it is a deterrent to proxy fraud.
(6) While the server access time stamp requires real-time connection, the attendance information is sent by e-mail after the time stamping, so the access is concentrated and the response is poor, or the communication system is temporarily down. There is no problem.
JP 2004-355344 A

  However, the attendance management method and system described in Patent Document 1 have the following problems.

(1) A terminal device having an imprint data generation function and a mobile phone connection function is indispensable for each dispatch destination. Since it is necessary to install dedicated terminals in advance at all small branches, offices, and care recipients' homes, costs are high and it is difficult to respond flexibly to sudden changes.
(2) Since third parties outside the company do not intervene in the processes of generating time stamp data, collecting data on the host computer, and subsequent various attendance processes, fraud is possible if the persons in charge in the company cooperate.
(3) Since each processing time such as the time of stamping depends on a clock built in each processing apparatus, an accurate time recording is not left. In addition, it is not possible to completely prevent fraud caused by changing the setting of a clock built in each device.
(4) If the identification data indicating the work location set in the stamp data generation terminal is falsified, it is not impossible to impersonate the work location.
(5) Since mobile phones cannot be borrowed or borrowed easily (because business information and personal information necessary for work are stored), the deterrence effect of proxy fraud is expected to some extent, but it cannot be completely prevented. , The risk of acting fraud remains.

  Therefore, the technical problem of the present invention is that the dispatching work that allows the temporary staff or the staff of the temporary staff to go to and from the dispatch destination and the work man-hours can be managed accurately and at low cost while completely preventing fraud.

And a function.

(4) Further, in the dispatch work management system according to claim 4 of the present invention, the mobile terminal possessed by the worker has a time acquisition function for acquiring an accurate time from GPS data or a mobile phone base station, A time stamp adoption function that adopts these GPS times or mobile phone base station times as the time stamp is provided, and the data center has a function of maintaining an accurate time synchronized with Coordinated Universal Time (UTC). And a storing function for storing and managing the stamped data together with the accurate time when the stamped data is received.

( 5 ) Further, in the dispatch work management system according to claim 5 of the present invention, an error occurs at the time of accessing the ID identification medium or at the time of each communication operation in the GPS, mobile phone base station or other devices. In some cases, an error log is stored, and the error log is collected and managed in the data center.

( 6 ) Further, the dispatching work management system according to claim 6 of the present invention accesses the data center from the communication terminal of the dispatching company via a network, and determines the period, worker information, or work place. When output conditions such as information and classification are specified, the corresponding stamp information data is extracted from the stamp information database in accordance with the specified conditions, and the result data file is created and transmitted to the communication terminal of the dispatching company. It is characterized by that.

( 7 ) Further, in the dispatch business management system according to claim 7 of the present invention, the ID identification medium is an IC card, the portable terminal has an IC card writing function, and the storage device of the IC card includes: Each stamping information up to the previous time is stored in accordance with the unused capacity of the storage device.

According to the means according to claim 1 described in the above (1), in the dispatch destination, for example, only an ID identification medium comprising an IC card or an RFID tag having a card ID and a dispatch destination identification code, and a portable terminal of a mobile phone Since the start and end of work or work can be stamped using this, the attendance destination such as the person in charge of the office or the person being cared for can be maintained and managed while accurately managing the attendance status and work man-hours with a simple system configuration. Since it is engraved by using the ID identification medium, it is possible to properly manage the dispatching work with fraud suppression.

Further, according to the means according to claim 1 described in the above (1), when the mobile terminal is in a communicable state, immediately after the time stamping, the time stamp information is transmitted to the data center in real time, and the fraud suppression effect is obtained. Although it can be demonstrated, if real-time transmission is not possible, it can be stored inside the mobile phone and then retransmitted when communication is possible. In addition, when data is collected without re-sending, if the number of collected data reaches a certain number, the subsequent processing is prohibited, so the worker (visiting caregiver) may interfere with work. Since the data must be retransmitted to arrive, problems due to data storage can be prevented.

  Furthermore, according to the means according to claim 1 described in (1) above, a business center that dispatches temporary staff or staff to record and manage time stamp information by a data center that is a third party with no interest. The burden on the user is reduced and data alteration can be suppressed by the intervention of a third party.

  According to the means according to claim 2 described in the above (2), the data center as the third party sends the time stamp returned from the time stamp issuing organization to the result data file to which the electronic signature of the data center is attached. Since the data file is transmitted to the dispatching company after the token is granted, the dispatching company can objectively prove the issuer of the data file and non-tampering in the future. For example, it is possible to easily prove that there is no fraud by presenting a performance data file with an electronic signature and time stamp when auditing from a local government etc. to a care provider, which is performed irregularly .

  According to the means according to claims 3 and 4 described in (3) and (4) above, the position information acquired by GPS at the time of engraving or the position information acquired from the mobile phone base station is stored in the ID identification medium. In order to compare and confirm with the location information, it is possible to prevent location information fraud, and at the time of stamping, to acquire the exact time from GPS or mobile phone base station, and to set this time as the stamping time, Since the time can be set to a more accurate time and the time of the internal clock of the portable terminal is not used, fraud due to changing the clock can be prevented. In addition, when the time stamp data is received at the data center, it is stored together with the accurate time synchronized with the Coordinated Universal Time (UTC), and the accurate time is used consistently throughout the system, thereby preventing time-related fraud. be able to.

According to the means of claim 5 described in the above (5), when an error occurs , error log data of ID identification medium access / GPS / base station is also transmitted, so that follow-up investigation is possible later.

  In addition, when accurate time acquisition is not possible, the time of the internal clock of the mobile phone is used, but the validity / validity is verified by tracking the correlation between the time stamped data, each error log, and data center registration information. You can check sex.

According to the means described in claim 6, described in the above (6), the period and various other information specified by the dispatch operator, or employment (temporary) area, joining local government, the level of care required, in charge of care manager The time stamp data required for each category is collected from the time stamp information database, and a record data file is created and sent to the communication terminal of the dispatch operator. Can be received under specified conditions, making it possible to facilitate the attendance management of temporary staff and the calculation of temporary compensation.

Save According to the measures of claim 7 described in the above (7), by the ID discrimination medium dispatch destination accepting dispatching workers possessed the IC card, also the time stamped data in the IC card In addition, since new data can be left in first-in first-out, it can be dealt with when trouble occurs in the data due to some kind of trouble (preliminary data). The deterrent effect can be further enhanced.

As described above, according to the management system for dispatching work according to the present invention, the dispatching destination has a simple configuration of an ID identification medium made up of an IC card or an RFID tag and a portable terminal of a mobile phone, and the attendance status and work man-hours. For example, since it is engraved using a non-contact IC card held by the care recipient at the visited site, it can be confirmed that the other party has been visited reliably. Since the consent of the care recipient is required at the time, fraud becomes more difficult and proper management by the dispatching company becomes possible.

  In addition, the time stamp data is given the check result of the position information from the GPS or mobile phone base station and the exact time from the GPS or mobile phone base station, and is always the location by the position information check. In addition, because it does not use the internal clock of the mobile phone, it is not possible to make fraud to change the time. "Or" an act of changing the time setting of the internal clock of the device to fake the time "is completely impossible, and the reliability of the stamped data can be further improved.

  In addition, by leaving an error log when access to each system is not possible, it is possible to perform a tracking check together with the stamped data and data center registration information, and a third-party data center is involved. Combined with the data falsification prevention effect and the provision of digital signatures and time stamps, the data issuer and the ability to prove non-falsification can be further enhanced in the future. Can do.

  Furthermore, when auditing from a local government to a care provider performed irregularly, it is possible to easily prove that there is no fraud by presenting a performance data file with a time stamp.

That is,
1. Fraud suppression / prevention effect on individual stamped data
2. Data collection, aggregation, and management by a third party with no interest = Data neutrality
3. Unable to tamper with actual data by time stamp authentication
In addition, the data center acts as the collection and management of each individual data and the complicated fraud prevention system, so the burden on the care provider is reduced and nursing care is provided even to small and medium businesses. Service business management becomes easier.

  Hereinafter, the embodiment of the management system for dispatching work according to the present invention described above will be described with reference to the drawings. FIG. 1 is a configuration diagram illustrating the entire visiting care management system according to an embodiment of the present invention. In the figure, 10 is a temporary worker (temporary care provider) that dispatches a temporary employee or temporary staff (visiting caregiver), 20 is a destination (temporary caregiver's home) where the temporary employee or temporary staff is dispatched, and 30 is the first. Data center as three parties, 40 is a time stamp issuing organization, 50 is a mobile phone related business provider that provides various mobile phone services, 60 and 70 are an Internet line network and a telephone line network that connect the above parts to each other, Reference numeral 80 denotes a GPS satellite for acquiring position information and standard time, and 90 denotes a mobile phone base station.

11 is a communication terminal of a temporary worker 10 (care provider), 12 is a mobile phone (mobile terminal) possessed by a worker 13 (temporary employee, temporary staff, visiting care worker, etc.) dispatched by the temporary worker 10, 21 Indicates a non-contact type IC card (ID identification medium) possessed by a dispatch destination (a person in charge of a dispatch reception office or a care recipient).

The IC card 21 has data areas of a card ID, a dispatch destination identification ID code (a dispatch destination identification code) , a dispatch destination name (name), a dispatch destination location information, and the last stamped data in an internal storage device. Specifically, a non-contact readable / writable IC card medium represented by Felica (registered trademark of Sony Corporation) is used.

  Of the data held in the internal storage device, the card ID is IDm and is a unique code for each card, which is recorded at the time of card manufacture and is fixed data that cannot be rewritten. Also, the dispatch destination identification ID code is an identification code assigned to each dispatch destination, and the dispatch destination name (name) is the name of the care recipient who holds the IC card, the name of the establishment that accepts the dispatch, etc. Yes, the dispatch destination location information is the latitude / longitude value indicating the location of the care recipient's home or business location where the IC card is placed, and the stamping data is the unused capacity of the memory. The fixed data such as the dispatch destination identification ID code, the dispatch destination name, and the position information is stored in advance and distributed to each house or business location that is the dispatch / visit destination.

  In the mobile phone 12 described above, unique information (worker ID, worker name, etc.) of the worker 13 (temporary staff, visiting caregiver) is stored in advance, and the worker 13 himself carries it. In addition to input functions such as key switches, display functions, and standard functions such as voice input / output, the cellular phone 12 receives radio waves from the GPS satellite 80 and a read / write function to the (non-contact) IC card. A function of receiving time information and calculating position information from the orbit of each satellite and a time difference; a function of communicating with the mobile phone base station 90 to acquire accurate time and position information; and a mobile phone base station 90 A function for transmitting / receiving data to / from the data center 30 via the communication network 60 such as the Internet, and an application program (for example, i-αppli “registered trademark of NTT DoCoMo, Inc.”) It is set in advance and has a memory for storing time stamping data and failure information (error log). Worker 13 (temporary staff, visiting caregiver) It is intended to bring to dispatch and visited.

  Next, the above-mentioned data center 30 is for collecting various information such as dispatch stamp data and providing a fraud prevention service from the standpoint of a third party. 60 and communication functions, accurate time functions synchronized with Coordinated Universal Time (UTC) (by various time synchronization systems such as NTP), and time stamps collected by the dispatcher for each period and classification Data file creation function, electronic signature generation key Kds, electronic signature assigning function, time stamp request creation function including hash value, etc., and time stamp information database 32 (each time stamp data and error log data) And a computer device 33 having these functions.

  Next, the time stamp issuing organization 40 described above returns a time stamp token in response to a time stamp request from the client, and provides a time stamp authentication service. A function (based on a reference clock 41 such as an atomic clock that accurately and fairly clocks time), a signature generation key Kts unique to the time stamp issuing organization, a time stamp issue request verification function, a time stamp issue function, have.

  The time stamp service protocol such as the time stamp request and the time stamp token is standardized in ISO / IEC18014, RFC3161, JISX5063, and the like. These protocol time stamp issuing systems are composed of a time stamp issuing organization that issues time stamps and a client that issues a time stamp issuing request for the purpose of digital data existence time certification and non-falsification certification.

  Next, a temporary worker, a staff, or a temporary worker 10 who sends a visitor is a temporary staffing company, a nursing care service provider, a small-scale company or business that has many stores, and the period and classification are determined from the communication terminal 11. Designated data is received from the data center 30, and attendance management of temporary staff (visiting caregivers) is performed.

Next, the flow of the process of the present invention will be described by taking home care as an example.
≪Process at dispatch destination 20≫
(A) It is assumed that an IC card 21 (FeliCa card) for specifying a work place (caregiver person) is distributed in advance to the work place (caregiver person).
(B) The worker (visiting caregiver) visits the place of work (caregiver's home) with the mobile phone 12 equipped with the dispatching (visiting care) stamping processing application software (i-appli).
(C) For work (service) content, make advance preparations such as explanations and meetings in advance.
For example, both sides confirm the care plan submitted by the care manager.
(D) Operate the cellular phone 12 to perform a service start time stamping process. Details of the stamping process will be described later.
(E) Worker 13 (visiting caregiver) performs the specified service.
(F) When the service ends, the service end time stamping process is performed.
(G) If a plurality of tasks (services) on the day are scheduled, steps (C) to (F) are repeated, and service start and service end are marked for each task (service).

  The stamping process performed using the IC card 21 described above is performed by operating the above-described cellular phone 12 and starting a stamping process application software (for example, created by an i-appli) that is mounted in advance. Thereafter, the process proceeds according to the stamping process flowchart of FIG.

  In the first step S1, an initial screen stamping menu screen (FIG. 3) is displayed. When any one of the menus is selected, the content selected in step S2 is determined, and the service start or end is selected. If yes, the process proceeds to step S3. In step S3, the processing code (01 or 02) corresponding to the selected service start or end is stored in a predetermined area. When service start is selected in step S2, a service menu (FIG. 4) is displayed. When a corresponding service is selected in step S4, a code corresponding to the selected service is stored in a predetermined area.

  Next, when the IC card 21 is displayed close to the display unit 12A of the mobile phone 12 (not shown, voice guidance or the like may be used together), the care recipient 22 holds the IC card 21 over the mobile phone 12. In step S5, each card data (IDm, dispatch destination identification ID code, dispatch destination name, dispatch destination position information) is read from the IC card 21 in a non-contact manner. When the reading is performed normally, the display for bringing the IC card 21 closer is changed, and the completion of reading is clearly indicated to the operator. If reading is not completed normally within a certain period of time, error log data indicating that the IC card cannot be read is created and stored, and the process is continued. The error log data indicating that the IC card cannot be read is created by setting the processing code to 06 (card read error) in the stamping information data shown in FIG.

  In the next step S6, reception from the GPS satellite 80 is performed, and the reception result is checked. If reception is OK, the process proceeds to step S7 to acquire time data and calculate position information. If reception from the GPS satellite 80 is NG in step S6, error log data indicating that GPS reception is not possible is received in step S13. Create and save. The GPS error log data is created by setting data (appropriate data) in each area after setting 03 (GPS error) in the processing code in the stamp information data of FIG. Next, after receiving position information and accurate time from the mobile phone base station 90 in step S14, the process returns to step S8.

  Note that some mobile phones 12 have a function of automatically correcting the time by communicating with the mobile phone base station 90. In this case, apart from the automatic time correction function, an accurate time at that time is intentionally received from the mobile phone base station 90. If connection to the mobile phone base station 90 cannot be established, error log data indicating that the mobile phone base station cannot be received is created and stored as in the case of the GPS satellite 80. In this case, 04 (base station error) is set as the processing code.

  Next, the process proceeds to step S8, where the position information read from the IC card 21 and the position information calculated from the data received from the GPS satellite 80 or acquired from the mobile phone base station 90 are compared and checked. judge. The determination result is stored in a predetermined area, and the process proceeds to the next step S9. Although not shown in the figure, when the determination result is NG, an error may be output by display or sound. In step S9, the stamp information shown in FIG. 5 is created. Specifically, the processing code (stored in step S3), the IDm of the IC card 21 read in step S5, the ID code of the worker 13 preset in the mobile phone 12, and the step S4 Service code corresponding to the service content selected in (1), the current time (accurate time acquired from the GPS satellite 80 or the mobile phone base station 90, and if both the GPS satellite 80 and the mobile phone base station 90 cannot be received, the mobile phone The time of the internal clock of the telephone 12), position information (data read from the IC card 21 and data acquired from the GPS satellite 80 or the mobile phone base station 90 and the result of the comparison and determination), the identification ID code of the dispatch destination 20, Further, the name of the dispatch destination 20 or the name of the worker may be included. Furthermore, part or all of the created stamp information may be displayed, and the process may proceed to the next transmission process after the confirmation input operation.

  Next, the process proceeds to step S10, where the created time stamp information and each error log data generated so far are sent to the data center 30 together. If the transmission check at step S11 is OK, the time stamp is entered. After writing the time data into the IC card 21 in step S12, the time stamping process is terminated and the process returns to the standby state. In the writing process, as in step S5, guide display is performed so that the IC card 21 is brought close to the display unit 12A of the mobile phone 12 (not shown, voice guidance or the like may be used). Have the care recipient 22 hold the IC card 21 over the mobile phone 12 and write to the IC card 21 without contact. If writing is not completed successfully within a certain time, set the processing code 07 (card write error) and create error log data that cannot be written to the IC card in the same way as the previous error log data. ,Send.

  On the other hand, if the transmission check in step S11 is NG, error log data in which the processing code is set to 05 (transmission error) is created and stored, and the transmission information is stored in the internal memory of the mobile phone 12 in step S15. Thereafter, the engraving process is terminated and the process returns to the standby state. The transmission information stored in the internal memory of the mobile phone 12 can be retransmitted later from the menu.

[Reprint processing of stamping information]
The stamp information and error log data stored in the mobile phone 12 cannot be deleted by operation. Since these are erased for the first time when transmission to the data center 30 is completed, they have a fraud prevention effect. If that had been pooled data without retransmission, workers 13 (Visit caregivers) for the subsequent processing Once become a certain number of cases is configured so that is prohibited re-sent in order to interfere with the business I have to do it.

  Further, if a transmission error occurs in step S11 and there is stored stamping information or various error log data, it can be retransmitted manually from the menu. If there is no saved retransmission data, [3. Data retransmission] cannot be selected on the time stamp processing menu screen.

  In step S1 of FIG. 2, the initial screen stamping process menu screen (FIG. 3) is displayed. When [3. Data retransmission] is selected, the process proceeds from step S2 to step S16 to step S17 to execute data retransmission processing. Then, after setting a retransmission flag and a retransmission time for each piece of stored transmission information (time stamp data and various error log data), all the transmission information is transmitted to the data center 30.

  The transmission information transmitted normally as described above is erased from the memory of the mobile phone 12, and if the transmission is not completed normally, a transmission error in which the processing code is set to 05 (transmission error) as in step S11. Log data is created and saved, and transmission information that has not been transmitted is left in the memory of the mobile phone 12 as it is. (Save until next retransmission.)

≪Processing at data center 30≫
Since the data center 30 which is a third party records and manages time stamp information, the data center 30 has an advantage that leads to fraud deterrence against the worker 13 (visiting caregiver) and the dispatching company 10.

[Time stamp information reception processing]
The data center 30 receives the time stamp information transmitted from the mobile phone 12 owned by the worker (visiting caregiver), gives an accurate time synchronized with Coordinated Universal Time (UTC), and enters the time stamp information database. Record. In addition, by recording the exact time at the time of reception, it is possible to perform time-series tracking / reason check, thereby exhibiting an illegal deterrent effect.

[Actual data file transmission processing]
Furthermore, the data center 30 accepts access (browser, standard e-mail, etc.) from the communication terminal 11 of the dispatching company 10 (nursing care company), period (year / month / day), worker information, work place information. When the designation of the output condition such as classification is received, the corresponding stamp information data is extracted from the stamp information database according to the specified condition, and the result data file (format such as CSV, PDF) is created and created. A data center electronic signature is given to the actual data file using the electronic signature generation key Kds.

  Next, the data center 30 calculates a hash value of the actual data file to which the electronic signature is given, creates a time stamp request (issue request) including the hash value, transmits the request to the time stamp issuing organization, The time stamp token returned from the stamp issuing organization 40 is attached to the record data file to which the electronic signature is attached, and then sent to a dispatching business operator (care provider). The dispatching company 10 (nursing care provider) can add up the nursing care points based on the received record data file of the stamping information and apply to the local government.

[Result data file verification process]
On the other hand, when the dispatching company 10 (nursing care provider) or its auditing organization (local government, etc.) wants to verify the validity of the performance data file, it verifies the time stamp and electronic signature attached to the performance data file. Thus, it is possible to confirm that the issuer of the file and that the content of the file has not been tampered with.

  As described above, according to the management system for dispatch work according to the present invention, the non-contact IC card 21 held by the care recipient 22 is engraved, that is, obtained with the consent of the care recipient 22. Since it is engraved, improper engraving becomes very difficult. Moreover, it is proved that the place was visited at the time surely by combining the check of the position information and the time stamp by the accurate time (obtained from GPS or mobile phone base station).

  Further, if the error of the time stamp of the time stamp data and the reception time of the data center 30 is within a suitable range, and there is no error log related to the time stamp data before and after, there is little possibility that the data is fraudulent. It can be said. Since the system that checks each process of stamping and leaves a log in case of an error, the fact that there is no error log means that everything was processed smoothly and stamped, and most stamped data is this It becomes like this.

  That is, the position information and accurate time are obtained from the GPS satellite 80, the time stamp data is generated, and when the data center 30 is received without a time lag, the advanced technology and knowledge to counterfeit the radio wave from the GPS satellite 80. In general, it is almost impossible. In addition, in order to tamper with data read into the mobile phone 12, knowledge of installed applications and software creation technology are necessary, so that it is generally almost impossible. In addition, since it has a highly reliable stamping time and position information determination result and is received by the data center 30 in real time, there is no time to apply something. Therefore, there is almost no possibility of fraud.
