Examples of means for obtaining information indicating that the client is at or near the worker's workplace include location information services such as mobile phones and PHS, and GPS. Any means may be used as long as it is a means for obtaining information indicating that it is in the vicinity.

Because location information services such as mobile phones and PHS and GPS have errors, even when operating a client in the workplace, the workplace and the vicinity of the workplace may be within the error range. Even when a nearby client is operated, the workplace and the neighborhood of the workplace may be within the error range. In addition, if there is no error, or if there is an error and the method is very accurate, it may be possible to identify that a client in the workplace has been operated or that a client in the vicinity of the workplace has been operated. . Therefore, in claim 3, “workplace or the vicinity of the workplace” is described without distinguishing between the workplace and the vicinity of the workplace so as to cope with any case.

As described above, in the invention described in claim 3, there is a case where it can be specified only that the client is at or near the workplace. However, even if the client cannot be proved to be 100% at work, it can be proved that the client is at least in the vicinity of the work, so that it becomes an objective clue to know the date and time when the worker who operated the client was at the work. In addition, if you use a personal record that a worker has recorded, it will be more powerful evidence.

The invention according to claim 4 records and certifies the date and time when the worker was at or near the worker's workplace by a third party who is neither the worker nor the employer of the worker. A system that is operated by a worker and includes equipment at or near the worker's workplace or near the worker's workplace, wherein the worker is at or near the worker's workplace And a step of proving the date and time that the worker was at or near the worker's workplace, and the worker is at or near the worker's workplace. And a means for authenticating a worker who has operated the device at or near the worker's workplace and obtaining information for identifying the certified worker, and Means for identifying the date and time and the device used for authentication Means for obtaining information indicating that the workplace of the certified worker is or near the workplace of the certified worker, information for identifying the certified worker obtained by the above means, date and time of certification, and use for certification Means for associating and recording information indicating that the device is at or near the certified worker's workplace or the certified worker's workplace, wherein the worker is in the worker's workplace or the worker At the stage of proving the date and time in the vicinity of the workplace, the information for identifying the certified worker recorded by the above means, the date and time of certification, and the device used for certification are the workplace or certification of the certified worker. And means for issuing a certificate using information indicating that the worker is in the vicinity of the workplace.

Examples of the device include a GPS device, a device designed for the present invention, and the like. However, any device may be used as long as the device can be provided.

In the description, in order to use the words common to the inventions according to claims 1 to 3, there is a part in which the device is described as a client for convenience.

From here, what is common to claims 1 to 4 will be described.

The term “employer” used in the description refers to a person who hires a worker to receive labor and pays wages. In the notification to prevent overtime work by the Ministry of Health, Labor and Welfare, the term “user” is used in the same meaning, but in order to avoid the misunderstanding of “user” in the sense of using the device. , Dare to use the word "employer".

The term “workplace” used in the description refers to all places where workers work, not just within the employer's premises. For example, for a worker who is doing sales work, the place visited by sales is also the workplace.

As a means to authenticate workers, there are various methods such as a method using an ID and a password, a method using a physical feature such as a fingerprint or a retina, a method using an ID card, a method using an electronic certificate, etc. Alternatively, a combination thereof is conceivable, but any means can be used as long as it can authenticate the worker who operates the client.

There are various certificates to be issued, such as a certificate displayed on the screen, a paper certificate, an electronic certificate, or a combination of them. Anything is acceptable.

By using the present invention, it is possible for a third party who is neither this worker nor the employer of this worker to record and prove the date and time when the worker was at the workplace or the clue of when the worker was at the workplace. become. If the worker uses the present invention at the start / end of work, it becomes possible to record and prove the start / end time of the worker and to clarify the correct working hours. Further, if the present invention is used before and after the break time, the break time can be recorded and proved.

The present invention can be used only by the will of the worker regardless of the will of the employer. Therefore, even when the employer requests service overtime, recording the date and time when the worker was at the workplace in the present invention is a powerful proof when the wage for the service overtime is claimed later. On the contrary, by making the worker use the present invention at the will of the employer, it is possible to show that the employer does not allow service overtime.

By using the present invention, it becomes possible for a third party who is neither the worker nor the employer of the worker to record and prove the date and time when the worker was at the workplace. Therefore, the present invention can be a powerful proof both when requesting the employer to improve the service overtime and when paying the wage for the service overtime later, and can prevent the service overtime.

An example for carrying out the invention described in claim 1 is shown in the first embodiment. In the first embodiment, a communication means can be accessed via the Internet, a client can access the Internet via a work network, a personal computer equipped with a web browser, a server called a web server and a program called using a CGI (Common Gateway Interface), labor This is an example in which an ID assigned to each worker is used as information for identifying a worker, a method of using an ID and a password as authentication means, and an IP address and related information as information indicating that the client is at work.

FIG. 1 is a block diagram mainly showing a software configuration of the first embodiment. Reference numeral 101 denotes a third party server. The server communicates with the web browser of the client, the CGI (104) which is an interface for calling each means from the web server, authenticates the worker who operates the client, and obtains the ID of the authenticated worker Authentication means (107), date and time specification means (108) for specifying the date and time of authentication using a clock in the server, etc., information indicating that the client is at work and information related to the IP address Obtaining means for obtaining information indicating that the client is in the workplace (109), means for recording the information in association with each other (103), database for recording the information (102), and issuing a certificate using the recorded information Certificate issuing means (106). 110 is the Internet of communication means. 111 represents a worker's workplace. In the workplace, there is a client personal computer (112) operated by a worker (115). The client comprises a web browser (114). The client is assigned a global IP address (IP address that can directly communicate with devices on the Internet) (113), and the web browser uses this IP address to communicate with the web server. The IP address itself is information indicating that the client is at work, but in order to obtain more information, the reverse lookup function (116) of the DNS server that looks up the host name from the IP address, and the IP address is A whois server (117) of an IP address management organization (such as JPNIC) that checks the assigned organization is used.

FIG. 2 is a block diagram mainly showing a hardware configuration of the first embodiment. FIG. 2 is an example of a hardware configuration for realizing the software of FIG. 201 is a third party server. The server issues a control means (203) such as a CPU, a storage medium (202) for recording information, a communication means (204) for communicating with a client, a date and time specifying means (206) such as a clock in the server, and a certificate. A certificate issuing unit (207) and a storage medium (205) storing software of the system. The certificate issuing means may not need to be implemented as hardware when using only an electronic certificate without using a paper certificate. Reference numeral 208 denotes the Internet of communication means. Reference numeral 209 denotes a worker's workplace. The workplace includes a workplace network (210) and a client personal computer (211) operated by a worker (216). The personal computer of the client includes a control means (214) such as a CPU, a communication means (213) for communicating with a server, and an interface (215) operated by a worker. Further, a global IP address (212) is assigned to the client, more precisely, the communication means of the client, and communication with the server is performed using the IP address. Reference numerals 217 and 218 denote a reverse lookup function (217) of the DNS server that checks the host name from the IP address, and a whois server (218) of the IP address management organization that checks the organization name to which the IP address is assigned from the IP address.

FIG. 3 is a sequence diagram illustrating processing at a stage of recording that a worker is in the workplace in the first embodiment. The synchronous message in FIG. 3 expresses that processing is continued after waiting for a response to the message. Here, it demonstrates along the procedure which performs a process. A worker operates a personal computer (S301) of a client in the workplace to access a third party server (S302) (S304). The server requests input of ID and password (S305). When the worker inputs the ID and password (S306) and transmits them to the server, the IP address of the client and the port number used for communication by the client are also notified to the server (S307). This is an Internet specification, more precisely, a TCP (Transmission Control Protocol) specification used by a web server and a web browser for communication. The server authenticates the worker using the ID and password (S308). If the authentication fails (S309), it requests the input of ID and password again (S305). When the authentication is successful (S310), the ID of the authenticated worker is obtained (S311). The date and time of authentication is obtained using the date and time specifying means of the server (S312). From the notified IP address, an inquiry is made to the DNS / whois server (S303) about the host name associated with the IP address and the organization name to which the IP address is assigned (S313), and the DNS / whois server returns a reply. The host name and organization name obtained are obtained (S314). Associating the worker ID, date and time of authentication, client IP address, host name, organization name assigned IP address, and port number used by the client for communication, obtained in the above procedure Recording is performed (S315). Finally, the worker is notified that the recording has been completed (S316).

In the first embodiment, it is not necessary to record the port number. However, the port number may be required in other embodiments, and even in that case, the port number is also recorded for the same handling.

FIG. 4 is a flowchart illustrating the processing of the server at the stage of recording that the worker is at the workplace in the first embodiment. Here, it demonstrates along the procedure which performs a process. When there is an access from the client, the server process is started (S401). The client is requested to input an ID and password (S402). When receiving the ID and password from the client, the IP address of the client and the port number used for communication by the client are also notified (S403). Using the received ID and password, the server authenticates the worker (S404). If the authentication fails (S405), the ID and password are requested again (S402). When the authentication is successful (S406), the ID of the authenticated worker is obtained (S407). The date and time of authentication is obtained using the date and time specifying means of the server (S408). From the notified IP address, the DNS whois server is inquired of the host name associated with the IP address and the organization name to which the IP address is assigned (S409), and the host name returned from the DNS whois server And the organization name are received (S410). Associating the worker ID, date and time of authentication, client IP address, host name, organization name assigned IP address, and port number used by the client for communication, obtained in the above procedure Recording is performed (S411). Finally, the worker is notified that the recording has been completed (S412).

FIG. 5 is an example of a certificate issued in the first embodiment. FIG. 5 shows the date and time when the worker assigned the corresponding ID is authenticated using the information recorded above, the connection source information (information indicating that the client used for authentication is in the workplace), and This is a certificate that is listed in units of one month. In this certificate, there is a field for writing the name in addition to the worker ID. However, in some cases, it may be desirable to write information such as an address. Conversely, as long as the ID is described, it may not be necessary to describe the name. In such a case, in order to prove that the certificate belongs to the user, authentication is performed in front of the other party (in the first embodiment, authentication is performed by entering an ID and password). It may be necessary. Although it is not necessary to describe the port number in the certificate according to the first embodiment, the port number may be necessary in other embodiments, and the port number is also described for handling in the same manner as that case.

FIG. 6 is a flowchart illustrating processing for issuing a certificate in the first embodiment. FIG. 6 is a process for issuing the certificate of FIG. Here, it demonstrates along the procedure which performs a process. The ID of the worker to be certified and the date to be certified are designated (S602). The name and ID of the worker to be certified and the date of certification are written in the certificate (S603). The process between S604 and S607 is repeated until all the information for one month has been written. Information on the date and time of the worker to be certified is taken out from the recorded information (S605). A line of the certificate is written using the extracted information (S606). When the writing of information for one month is completed, the process ends (S608). In addition, the word “write” here is not limited to writing on a paper certificate, but when displaying on the screen, creating an electronic certificate, or creating another certificate. But it shows you to create each certificate.

With this certificate, the worker assigned the listed ID operated the client listed on the connection source on the date and time listed, that is, was in the same location as the client listed on the connection source Can prove. When the present invention is used by operating a client at a worker's workplace, the connection source becomes a client at the workplace, so that it is possible to prove that the worker was at the workplace. This certificate can be a powerful proof both when the employer is requested to improve service overtime and when he / she is billed later for wages for service overtime, and can prevent service overtime.

(Embodiment 2)
An embodiment for carrying out the invention described in claim 1 is shown in a second embodiment. FIG. 7 is a block diagram illustrating a configuration of the second embodiment. In the second embodiment, an IP address conversion device (705) such as a firewall or a broadband router is provided between the Internet (702) and the worker's workplace network (706). ) Is an example in which a private IP address (an IP address that is valid only within a specific network and cannot directly communicate with devices on the Internet) (707) is assigned. There are many examples of such a configuration in a corporate network. In FIG. 7, the internal configuration of the third-party server (701) and the client personal computer (708), the DNS server and the whois server are the same as in FIGS.

In the second embodiment, the IP address and port number notified in S307 of FIG. 3 are not the IP address (707) and port number of the client operated by the worker, but the IP address (704) and port of the IP address translation device. Number. Recording the IP address of the IP address translation device does not provide information for identifying which client has accessed. However, since it is certain that access was made via an IP address translation device between the Internet and the worker's workplace network, the client is connected to the inside of the IP address translation device, that is, to the workplace network. Can prove that the client is in the worker's workplace. Therefore, the implementation mobile phone 2 can be handled in the same manner as in the first embodiment.

The sequence diagram and flowchart showing the process of recording the worker at the workplace in the second embodiment are the same as those in FIGS. 3 and 4 in the first embodiment. The second embodiment can be used as it is.

Certificates similar to those shown in FIGS. 5 and 6 of the first embodiment can also be used. When interpreting the certificate, since the connection source is the IP address translation device, it is clear that the access is via the workplace network, and it can be proved that the client was at the workplace.

(Embodiment 3)
An example for carrying out the invention described in claim 1 is shown in a third embodiment. FIG. 8 is a block diagram illustrating a configuration of the third embodiment. The third embodiment is an example in which the IP address translation device (805) is not dedicated to the workplace of the worker but is shared with other organizations or individuals (811 to 813) in the second embodiment. Also in FIG. 8, the internal configuration of the third party server (801) and the client personal computer (809), the DNS server and the whois server are the same as those in FIG. 1 and FIG.

In the third embodiment, even if the IP address (803) of the IP address translation device is recorded, it cannot be proved that the client is at work. In this case, if the access record (log) of the IP address conversion device is checked based on the IP address (803), the port number (804), and the date and time of access, whether the accessed client is at the worker's workplace. Can be determined. Therefore, if the port number is recorded, the third embodiment can be handled in the same manner as the first embodiment. In the first and second embodiments, the port numbers that do not need to be recorded are recorded in the same manner as in the third embodiment. However, there is a possibility that the access record (log) may be erased if time passes after recording. Even in that case, it is possible to prove which IP address translation device has been passed, so that it becomes a clue as to whether the accessed client is in the workplace.

The sequence diagram and the flowchart showing the process of recording the fact that the worker is in the workplace in the third embodiment are the same as those in FIGS. 3 and 4 in the first embodiment. The third embodiment can be used as it is.

Certificates similar to those shown in FIGS. 5 and 6 of the first embodiment can also be used. When interpreting the certificate, it is necessary to check with the administrator of the shared IP address translation device based on the IP address, port number, and date / time of the connection source to confirm whether the client used at the workplace There is. In this case, a public disclosure order is probably necessary.

The case where the IP address is dynamically assigned is almost the same as that of the third embodiment. In this case, it is necessary to check with the provider that dynamically assigned the IP address based on the IP address and the date and time whether the used client was in the workplace. Again, a public disclosure order is probably necessary.

(Embodiment 4)
An embodiment for carrying out the invention described in claim 2 is shown in a fourth embodiment. FIG. 9 is a block diagram illustrating a configuration of the fourth embodiment. The fourth embodiment is an example in which the personal computer (905) of the client is in the vicinity of the workplace (903) instead of the worker's workplace (907) in the first embodiment. In FIG. 9, the internal configuration of the third-party server (901) and the client personal computer (905), the DNS server and the whois server are the same as in FIGS.

The fourth embodiment is an example in which the present invention is used by a client in the vicinity of the workplace when a worker's workplace does not have the necessary equipment or when the present invention cannot be used even if there is equipment. . An example of a client in the vicinity of a workplace is an internet cafe computer.

The only difference between Embodiment 4 and Embodiment 1 is that the client is not in the workplace, but in the vicinity of the workplace. Therefore, the fourth embodiment can be handled in the same manner as the first embodiment.

The sequence diagram and flowchart showing the process of recording that the worker is in the vicinity of the workplace in the fourth embodiment are the same as those in FIGS. 3 and 4 in the first embodiment. The server can be used in the fourth embodiment as it is.

Certificates similar to those shown in FIGS. 5 and 6 of the first embodiment can also be used. The certificate according to the fourth embodiment proves the date and time when the worker was in the vicinity of the workplace, and does not directly prove the date and time when the worker was at the workplace. However, it is certainly an objective clue to know the date and time when the worker was at the workplace, and if it is used together with a notebook that the worker has recorded, it will be more powerful evidence.

In the first to fourth embodiments, the configuration and processing on the third party server side are the same. The difference is only on the client side. Therefore, if one server is prepared, all cases of Embodiments 1 to 4 that vary depending on the client side can be handled.

An embodiment for carrying out the invention described in claim 2 is shown in a fifth embodiment. The fifth embodiment is an example in which an automatic ticket gate of a station used by a worker for commuting is used as a client, and a method of reading a commuter pass with an ID using an automatic ticket gate as an authentication means. The ID of the commuter pass is used as information for identifying the worker.

FIG. 10 is a block diagram mainly illustrating a software configuration of the fifth embodiment. Reference numeral 1001 denotes a third party server. The server uses a communication means (1004) for communicating with the client, a date specifying means (1006) for obtaining the date and time of authentication, a means (1003) for associating and recording information, a database (1002) for recording information, and using the recorded information And a certificate issuing means (1005) for issuing a certificate. Reference numeral 1007 denotes a communication means. Reference numeral 1008 denotes an automatic ticket gate of the client. The automatic ticket gate of the client is a communication means (1009) that communicates with the server, the worker (1012) reads and authenticates the ID ticket (1011) presented on the client's automatic ticket gate, and authenticates the ID of the authenticated ticket Authentication means (1010) for obtaining FIG. 10 does not describe a portion of the automatic ticket gate that is not related to the present invention.

FIG. 11 is a sequence diagram showing processing at a stage of recording that a worker has presented a commuter pass on an automatic ticket gate at a station used for commuting in the fifth embodiment. The asynchronous message in FIG. 11 represents that processing is continued without waiting for a response to the message. Here, it demonstrates along the procedure which performs a process. The commuter pass with ID presented by the worker is read at the automatic ticket gate (S1101) of the station that the worker uses for commuting (S1103). Authentication is performed using information on the commuter pass (S1104). If the authentication fails (S1105), it requests the presentation of a commuter pass again (S1103). If the authentication is successful (S1106), the commuter pass ID and the station name where the client's automatic ticket gate is located are transmitted to a third party server (S1102) (S1107). The date and time of authentication is obtained using the date and time specifying means of the server (S1108). The ID of the authenticated commuter pass, the date and time of authentication, and the name of the station where the client's automatic ticket gate is obtained in association with each other are recorded in association with each other (S1109). In FIG. 11, portions that are not related to the present invention in the automatic ticket gate processing are not described.

FIG. 12 is an example of a certificate issued in the fifth embodiment. FIG. 12 shows the date and time when a worker having a commuter pass with the corresponding ID uses the information recorded above to present and authenticate the commuter pass on the client's automatic ticket gate, the name of the station where the client's automatic ticket gate is located, This is a certificate that is listed in units of one month. The procedure for issuing the certificate in FIG. 12 is the same as that in FIG.

With this certificate, it can be proved that a worker who has a commuter pass with the described ID presented the commuter pass on the automatic ticket gate of the described station on the described date and time. The certificate of the fifth embodiment proves the date and time when the worker presented the commuter pass on the automatic ticket gate of the station used for commuting, and does not directly prove the date and time when the worker was at the workplace. However, it is certainly an objective clue to know the date and time when the worker was at the workplace, and if it is used together with a notebook that the worker has recorded, it will be more powerful evidence.

(Embodiment 6)
An embodiment for carrying out the invention described in claim 3 is shown in the sixth embodiment. In the sixth embodiment, a mobile phone network is used as a communication means, a mobile phone that can use a location information service for a client, and a location information service of a mobile phone is used as a means for obtaining information indicating that the client is at or near the workplace. It is an example. As information for identifying a worker, an ID assigned to each worker is used. As an authentication method, an example using a fingerprint reading device built in a small number of mobile phones may be considered, but this time, an example of a method using an ID and a password that can be used with more mobile phones. explain. In addition, since an ID is assigned to each mobile phone, an authentication method in which the mobile phone itself substitutes for an ID card can be considered.

At the time of the filing of the present invention, a method for specifying the position using both the radio wave from the GPS satellite and the radio wave from the base station has been put into practical use for the mobile phone location information service. Is possible. Many attempts have been made to improve accuracy, and further improvement in accuracy can be expected in the future.

Reference numerals 1311 to 1313 denote GPS satellites for specifying positions. 1314 represents the workplace of the worker. The worker (1320) operates the client's mobile phone (1315) at or near the workplace, and records the date and time when the worker (1320) was at or near the workplace. The mobile phone of the client uses a control means (1317) such as a CPU, a communication means (1316) for communicating with the server, an authentication means (1318) for authenticating a worker in cooperation with the server authentication means, and a location information service. And a position specifying means (1319) for specifying the position of the client.

FIG. 14 is a block diagram mainly illustrating a hardware configuration of the sixth embodiment. FIG. 14 is an example of a hardware configuration for realizing the software of FIG. Reference numeral 1401 denotes a third party server. The server issues a control means (1403) such as a CPU, a storage medium (1402) for recording information, a communication means (1404) for communicating with a client, a date and time specifying means (1406) such as a clock in the server, and a certificate. A certificate issuing unit (1407) and a storage medium (1405) storing software of the system. Reference numeral 1408 denotes a cellular phone network as a communication means. Reference numeral 1409 denotes a mobile phone base station. Reference numerals 1410 to 1412 denote GPS satellites for specifying positions. 1413 represents the workplace of the worker. The worker (1415) records the date and time when he / she was at or near the workplace by operating the mobile phone (1414) of the client at or near the workplace.

FIG. 15 is a sequence diagram illustrating processing at a stage of recording that a worker is at or near the workplace in the sixth embodiment. Here, it demonstrates along the procedure which performs a process. The worker operates the client's mobile phone (S1501) at or near the workplace to access the third party server (S1502) (S1503). The server requests input of ID and password, and transmission of the client position (S1504). The worker inputs the ID and password (S1505), obtains the position of the client using the position specifying means (S1506), and transmits the ID, password and client position to the server (S1507). The server authenticates the worker using the ID and password (S1508). If the authentication fails (S1509), it requests the input of the ID and password again and the transmission of the client position (S1504). If the authentication is successful (S1510), the ID of the authenticated worker is obtained (S1511). The date and time of authentication is obtained using the date and time specifying means of the server (S1512). The worker ID, the date and time of authentication, and the position of the client obtained in the procedure so far are recorded in association with each other (S1513). Finally, the worker is notified that the recording has been completed (S1514).

FIG. 16 is an example of a certificate issued in the sixth embodiment. FIG. 16 shows a list of the date and time when the worker assigned the corresponding ID is authenticated using the information recorded above and the information of the connection source (the location of the client used for authentication) on a monthly basis. The certificate is listed in the table. The process of issuing the certificate in FIG. 16 is the same as that in FIG. Since there is an error in the location information service of the mobile phone and the magnitude of the error varies depending on the case, the magnitude of the error is also described in this example of the certificate. In some cases, it may be necessary to display a range of the error on the map instead of the size of the error.

With this certificate, it can be proved that the worker assigned with the described ID was at the described position on the date and time described. This certificate does not always prove that the worker is at the workplace because of the error in the location indicated. However, in the future, the improvement in accuracy is expected, and even if it cannot be proved that it was 100% at work, it can be proved that it was in the vicinity of the work, so the objective to know the date and time when the worker was at the work It is certain that it will be a clue, and if it is used in combination with a notebook that the worker has recorded, it will be more powerful evidence.

(Embodiment 7)
An embodiment for carrying out the invention described in claim 4 is shown in a seventh embodiment. Embodiment 7 is an example in which a GPS device capable of specifying a position using a GPS satellite is used as the device. As described in the description of the sixth embodiment, since the position to be specified in the seventh embodiment also has an error, the same consideration as in the sixth embodiment is necessary.

FIG. 17 is a block diagram illustrating a configuration of the seventh embodiment. As for the internal configuration of the GPS device, it is difficult to distinguish between software and hardware. Therefore, this figure is described without distinguishing between software and hardware. Reference numerals 1701 to 1703 denote GPS satellites for specifying positions. Reference numeral 1704 denotes a worker's workplace. The worker (1713) operates the GPS device (1705) at or near the workplace, and records the date and time when the worker was at or near the workplace. The GPS device includes a control means (1707) such as a CPU, an authentication means (1712) for authenticating a worker and obtaining information for identifying the authenticated worker, a date specifying means (1711) for specifying the date and time of authentication, a GPS Position specifying means (1710) for specifying the position of the GPS device using satellites, means for recording information in association (1708), storage medium for recording information (1709), certificate issuing means for issuing a certificate (1706).

The certificate issuing means here does not necessarily have to work with this GPS device alone. For example, connect to a printer to print a certificate, connect to a personal computer to transfer GPS device information and issue a certificate, take out an internal storage medium, read the information, and issue a certificate Such means can be considered. The GPS device itself can be used as a certificate.

FIG. 18 is a flowchart illustrating processing in a stage of recording that the worker is at or near the workplace in the seventh embodiment. Here, it demonstrates along the procedure which performs a process. When the recording procedure is started (S1801), authentication is first requested (S1802), and the worker is authenticated by the GPS device (S1803). If the authentication fails (S1804), the authentication is requested again (S1802). If the authentication is successful (S1805), the ID of the authenticated worker is obtained (S1806). The date and time of authentication is obtained using the date and time specifying means (S1807). Using the position specifying means, the position of the GPS device used for authentication is obtained (S1808). The worker ID, the date and time of authentication, and the position of the GPS device obtained by the procedure so far are recorded in association with each other (S1809). Finally, the worker is notified that the recording has been completed (S1810).

If this device is designed to be used by one person, it is not necessary to record the worker's ID. If you have the means to authenticate only one of them, you can prove that all recorded information belongs to that person.

The certificate issued in the seventh embodiment has the same contents as in FIG. 16 of the sixth embodiment. The process for issuing a certificate is the same as that in FIG. This is because the difference between the sixth embodiment and the seventh embodiment is that the client information is transmitted to the server and recorded on the server, or is recorded on the GPS device itself, and there is no difference in the recorded contents. .

In the seventh embodiment, since information is recorded on a device operated by a worker, measures to prevent the information from being tampered with in some cases are necessary. For example, it is possible to encrypt and record the information so that it cannot be tampered with, or use a case that leaves an open trace once the case is opened, but the information cannot be tampered with or tampered with. Any countermeasure can be used as long as it can be confirmed.
