Description

Technical Field

[0001] The present invention relates to an activity information management system that centrally manages activity information in each process from collection to final processing on a timeline, and can prevent unauthorized tampering of the activity information.

Background Art

[0002] In recent years, with the widespread use of mobile communication terminals, a method for managing information by linking the computer system of the mobile communication terminal and the Internet network has been proposed and is used in various fields such as health management, urban planning, and safety measures. In particular, with the spread of IoT (Internet of Things), various objects are connected to and utilized by clouds or servers through the Internet network.

[0003] In the field of industrial waste, various methods have been proposed for managing the process of waste via a server using mobile communication devices and systems through the Internet network. Among them, there is a simple method that can manage the activity records of the person in charge of the object by using an authentication card with a two-dimensional code and a mobile communication terminal.

[0004] For example, in Patent Document 1, by using a widely used mobile communication terminal to read the two-dimensional code of the authentication card held by the person in charge, management information including the read person-in-charge information, the date and time information when the authentication card was read, the location information, and the process information of the object is transmitted to the management server as the activity information of the person in charge. The activity information transmitted to the management server is recorded on the server in chronological order, and an activity information management system for creating a timeline is proposed. The activity information is transmitted to the management server every time the two-dimensional code is read by the person-in-charge's mobile communication terminal, and the activity record is accumulated on the management server to create and manage a timeline.

[0005] Even with a simple management system like the one in Patent Document 1, inaccurate activity information can be sent to the server due to human error in parts that are operated manually, such as inputting information about objects or selecting process information, resulting in errors such as operational mistakes, miscounting, input errors, or omissions. In such cases, it has been desirable to be able to edit the activity information, including errors, that has already been sent to the management server by correcting, adding, or deleting it. However, a system that simply makes the transmitted activity information editable has the problem that it is difficult to detect if a malicious actor edits the activity information with the intention of tampering with it. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Patent No. 7261554 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] The present invention has been made in view of the above circumstances, and aims to provide an activity information management system that centrally manages activity information by creating a timeline in which activity information of persons in charge at each stage from collection of the target object to final processing is transmitted to a server and the activity information is accumulated in chronological order, and by making it possible to check whether there are any errors in the activity information and to understand whether the activity information with errors has been corrected, added or deleted, thereby providing an activity information management system that has high credibility, transparency, reliability, traceability, and evidentiary value and can prevent unauthorized falsification. [Means for solving the problem]

[0008] The inventors of this invention have conducted extensive research to solve the above problems and have found that by providing a function to check and display the correctness (presence or absence of errors) of activity information, and a function to modify, add, delete, etc., of activity information, and a record of such actions (logs) linked to the modified activity information and recorded in the management server, it is possible to understand when activity information has been modified, and thus the above problems can be solved, leading to the completion of the present invention. In other words, the present invention is as follows.

[0009] (1) An activity information management system in which management information including personnel information read from a two-dimensional code attached to the personnel's authentication card, date and time information when the authentication card was read, location information, and information about the object is transmitted to a management server as activity information, and a timeline is created by recording the activity information transmitted to the management server in chronological order on the server, A monitoring function checks for errors in the activity information recorded in the aforementioned management server and displays the results of the check. The aforementioned monitoring function records in the management server, linked to the activity information in which the error was discovered, the traces (logs) of when the activity information containing the error was corrected, added, or deleted. An activity information management system characterized by having the following features. (2) The activity information management system described in (1), further comprising an anti-tampering function that prevents editing of activity information and traces of activity information. (3) The activity information management system described in (1), wherein the activity information further includes image information. (4) The activity information management system described in (1) above, wherein the activity information management system is a system for managing activity information relating to delivered goods, mail, recyclable materials, products, waste, or recycled resources. [Effects of the Invention]

[0010] According to the present invention, the activity information stored on the management server can be checked for errors by a monitoring function, and if an error is detected in the activity information, it can be edited to correct information using an editing function. Furthermore, the editing log (trace) when the activity information is modified, added, or deleted is linked to the edited activity information and recorded on the management server. This allows for a quick understanding of who modified which activity information and how, thereby enhancing the credibility, transparency, reliability, traceability, and evidentiary value of the activity information and preventing unauthorized tampering. [Brief explanation of the drawing]

[0011] [Figure 1] This figure shows a schematic of the first activity information management system of the present invention. [Figure 2] This is a diagram illustrating the monitoring function of the present invention. [Figure 3] This figure shows a schematic of the second activity information management system of the present invention. [Figure 4] This is a flowchart of the verification process in the present invention. [Figure 5] This diagram schematically illustrates the activity information management system for recyclable resources according to the present invention. [Figure 6] This is a diagram illustrating the resource recycling process in the present invention. [Modes for carrying out the invention]

[0012] The activity information management system of the present invention will be described in detail with reference to the drawings. It goes without saying that the present invention is not limited to the management system described later, and various modifications are possible.

[0013] <Activity Information Management System> The activity information management system of the present invention comprises a management server that collects and stores activity information transmitted via the Internet network from mobile communication terminals held by persons in charge of each process from the collection of an object to its final processing; a monitoring function that checks for input errors and other misinformation (errors) in the activity information transmitted to the management server and displays the results of the check; and an editing function that allows editing such as correction, addition, and deletion of errors found by the monitoring function, and leaves a record (log) of the editing. This system records the actions taken by persons in charge of an object as activity information in the management server and manages them centrally. As a result, activity information of persons in charge from the collection of an object to its final processing can be easily stored, the stored data can be edited as needed, and the recording of editing logs ensures the credibility, transparency, reliability, traceability, and evidentiary value of the edited data, thus providing an effect of preventing unauthorized tampering. In this invention, the object to be managed is a person's activity record (activity information).

[0014] Figure 1 is a schematic diagram of the first activity information management system of the present invention. As shown in Figure 1, the actions (activity information) of the person in charge at each stage from Site 1 to Site N are transmitted from the person in charge's mobile communication terminal to a management server that manages the activity information via the internet network. If the activity information concerns industrial waste, the activity information of the person in charge at each stage from collection and transportation to final processing is transmitted to the management server. Within the management server to which the activity information is transmitted, a timeline is created by accumulating the transmitted activity information in chronological order, and it is centrally managed. The activity information accumulated in the management server is checked for errors by a monitoring function, and the confirmation result is displayed. If an error is found in the activity information by the monitoring function, the error display data is edited as necessary by an editing function.

[0015] The aforementioned items include delivered goods, mail, recyclable materials, manufactured goods, waste, or recycled resources. Hereinafter, these items may be collectively referred to as "delivered goods, etc." Examples of the items to be delivered include products purchased at stores and other places, as well as products purchased at online shops, Internet auctions, and the like. The postal items refer to articles sent and received through postal services, including ordinary postal items (letters, correspondence, notices, postcards, sealed letters, periodicals, communication education and academic publications, etc.) of domestic and international postal services, small packet postal items, and the like. Examples of the resource items include minerals obtained from nature, natural resources such as land and water, marine resources, fishery resources, animal and plant resources derived from these, energy resources, food resources, and the like. The products refer to goods produced by adding human labor to the resource items and are tangible products. For example, they include household appliances, furniture, foodstuffs, clothing, sundries, industrial products, building materials, and the like. In contrast, intangible products are called services, such as communication, medical care, education, and the like. Examples of the waste items include general waste, industrial waste defined by the Waste Disposal Act, or specific general waste and specific industrial waste defined by the Special Measures Act on Countermeasures against Radioactive Substance Contamination. The recycling resources refer to the "recycling resources" defined in Article 2, Paragraph 3 of the Basic Law for Promoting the Formation of a Recycling-based Society. As stipulated in the same paragraph, they are useful ones among the waste items. That is, in accordance with the concept of recycling rather than discarding used products as waste, waste items that can be recycled as raw materials from the collected products or reused in another place are applicable.

[0016] The industrial waste refers to 20 types defined by the Waste Disposal Act among the waste items generated in business activities. Among industrial waste, those having properties harmful to human health or the living environment such as explosiveness, toxicity, and infectivity are classified as specially managed industrial waste. Further, among specially managed industrial waste, those containing waste PCBs, PCB contaminants, heavy metals, dioxins, organic chlorine compounds, etc. at a certain concentration or more are defined as specified harmful industrial waste. The general waste refers to those other than the industrial waste and includes business-related general waste, household waste, and specially managed general waste. The aforementioned specified general waste and specified industrial waste are waste with low levels of radioactive cesium contamination, other than the specified waste described later. Specified waste refers to waste located within the contaminated waste control area around the Fukushima Daiichi Nuclear Power Plant (waste within the control area), and waste with a radioactive cesium concentration exceeding 8,000 becquerels / kg that has been designated by the Minister of the Environment (designated waste). Specified waste is processed by the national government in accordance with the Act on Special Measures Concerning the Handling of Radioactive Material Contamination, while specified general waste and specified industrial waste are processed by municipalities, general waste treatment companies, waste generators, industrial waste treatment companies, etc., in accordance with the Waste Management Act and the Act on Special Measures Concerning the Handling of Radioactive Material Contamination.

[0017] The process from collection to final processing, in the case of items such as delivered goods, mail, recyclable materials, or manufactured goods, includes collecting the delivered goods, etc., sent by the client; transporting the collected delivered goods, etc., to a collection point where the delivered goods, etc., are gathered; sorting them by delivery area at the collection point; transporting the sorted delivered goods, etc., to collection points in the delivery area; and finally delivering them from the collection point to the recipient. If the object in question is waste, the process involves collecting the waste gathered at the site or collection point, transporting the collected waste to an intermediate or final processing plant (hereinafter sometimes collectively referred to as "processing plant"), unloading the waste upon arrival at the processing plant, and processing the unloaded waste within the processing plant. In addition, if necessary, the waste may be temporarily stored in a storage area before being transported to the processing plant. Furthermore, if the activity information includes the demolition of a house or other structure at the site, the process involves demolishing the house or structure, separating the demolished materials, transporting the separated waste, and processing it within the processing plant. Furthermore, if the object in question is a circulating resource, as shown in Figure 5, the process includes: (1) procurement and transport of raw materials (loading, unloading, storage, delivery, etc., the same applies hereafter); (2) manufacturing and transport of products; (3) collection, sorting (reduce), transport of consumed products, and transport of reused products (reuse); (4) collection, sorting, recycling, and transport of discarded products; and (5) collection and transport of reused and recycled resources. As shown in Figure 5, even in the case of circulating resources where products (resources) are (1) produced from raw materials, (2) consumed, (3) reused, or products (resources) that have been (3) consumed and (4) discarded are (5) recycled, and these are used to make (2) products again, activity information can be accumulated and managed at each stage of the process.

[0018] <Activity information> In this invention, activity information includes personnel information and management information. The aforementioned contact person information includes the contact person's personal information, is encrypted using an encryption code, and can be read by the mobile communication terminal described later. The aforementioned management information includes date and time information, location information, and process information obtained by operating the mobile communication terminal when the authentication card is read by the mobile communication terminal.

[0019] Activity information is sent to the management server through the following steps. First, the encrypted code is read via an application installed on the mobile communication terminal held by the person in charge. Once the encrypted code is read, the person in charge information contained within the encrypted code is temporarily stored in the internal memory of the mobile communication terminal. At the same time, date and time information indicating the date and time the encrypted code was read, and location information indicating the place where it was read, are automatically obtained from the mobile communication terminal and temporarily stored in the internal memory. Then, the current process information of the target object is selected from the screen of the mobile communication terminal, and a transmission operation to the management server is performed. As a result, the management information consisting of the person in charge information, date and time information, location information, and process information is sent to the management server as activity information.

[0020] Preferably, the transmission to the management server is performed after the encrypted code is read using a mobile communication terminal, the process information is entered using the mobile communication terminal, and the server is ready to receive the information, and then the transmission operation is performed. This prevents the transmission of incomplete activity information to the management server due to user error. The state in which data can be sent to the management server refers to the state in which a transmission operation can be performed on the screen of the mobile communication terminal. Before the process information is manipulated, even if a transmission operation is performed in the application, the activity information cannot be sent from the mobile communication terminal to the management server. It is preferable that the process information becomes available for transmission to the management server once it has been manipulated.

[0021] According to the present invention, the person in charge can send activity information to the management server with minimal operation, thus reducing the need for complicated procedures and minimizing the transmission of erroneous information. Furthermore, since activity information can be sent from the location, there is no need to travel to a location where a transmission terminal is installed.

[0022] The aforementioned persons include all individuals involved with the delivered goods. For example, this includes the client who requests the shipment of goods, the transportation company that collects and transports the goods, the sorting staff, the on-site staff who receive the goods at the delivery destination or demolish and separate the materials from the house, the transportation company that loads, transports, and unloads the goods, the storage staff, and the processing companies that perform intermediate and final processing.

[0023] The aforementioned mobile communication terminal can be one that the person in charge normally carries. Examples include mobile phones, smartphones, tablet devices, laptop computers, handheld terminals, and barcode readers. Among these, mobile phones or smartphones are preferred because they are lightweight, compact, widely available, and have functions such as reading two-dimensional codes, transmitting the read information to a management server, and taking pictures.

[0024] [Contact Person Information] In this invention, the person in charge information is information created for each person in charge of each process from collection to final processing, encrypted with an encryption code, and attached to the authentication card. The person in charge information is registered in advance before the creation of the authentication card, and an encryption code, encrypted based on the registered information, is printed on the authentication card and attached to it.

[0025] The aforementioned contact person information includes the names, departments, company names, addresses or locations, telephone numbers, individual company codes assigned to each company, vehicle numbers of transport vehicles, and individual vehicle codes assigned to each transport vehicle. Furthermore, in the case of persons engaged in businesses related to industrial waste, this includes the names, departments, company names, addresses or locations, telephone numbers, individual company codes assigned to each company, vehicle numbers of transport vehicles, individual vehicle codes assigned to each transport vehicle, and house codes assigned to each house being demolished. For those engaged in businesses related to recycled resources, the information provided may include the names, departments, company names, addresses or locations, telephone numbers, individual company codes assigned to each company, vehicle numbers of transport vehicles, and individual vehicle codes assigned to each transport vehicle, as shown in Figure 5. From this information, one or more pieces of information necessary for each person in charge are selected to form their person in charge information, which is then encrypted and attached to an authentication card distributed to each person in charge.

[0026] The aforementioned encrypted code is one that is encrypted so that it cannot be read by a mobile communication terminal that does not have a specific application or decryption program (hereinafter referred to as "application, etc.") installed. By having the aforementioned application, etc. pre-installed on the mobile communication terminals carried by the person in charge of each process, if the encrypted code is read without going through the application, etc., the read information will be garbled and will not be recognized properly. Therefore, there is no need to worry about a third party reading or misusing the person in charge information contained in the barcode, and security can be improved. If a two-dimensional code that does not contain person in charge information is read by a mobile communication terminal with the application, etc. installed, an error should be displayed on the mobile communication terminal screen or a warning sound should be emitted.

[0027] Examples of the aforementioned encryption codes include stacked two-dimensional codes such as PDF417, Micro PDF417, Code49, Code16K, Codablock, Supercode, Ultracode, RSScomposite, and AztecMesa; and matrix-type two-dimensional codes such as QR Code (registered trademark), Micro QR Code, SP Code, VeriCode, MaxiCode, CP Code, DataMatrix, DataMatrixECC200, Code1, AztecCode, Interactor Code, Card e, and Chameleon Code. Among these, QR Code is preferred because it does not require concern about the angle between the mobile communication terminal and the encryption code during reading, can be easily read with a camera, etc., and can be read even if it is dirty or damaged.

[0028] While one-dimensional codes (barcodes) can also be used as encryption codes, they are unsuitable for the activity information management system of the present invention because they can only contain a limited amount of information (around a few dozen characters) and can only barcode alphanumeric characters and symbols. On the other hand, IC tags can contain large amounts of information, but they are expensive in themselves, and require a dedicated reader, resulting in enormous management costs per object, which is undesirable. Furthermore, IC tags are not suitable for data encryption, and in this respect as well, they are unsuitable for the present invention.

[0029] [Management information] In the present invention, the management information includes at least date and time information, location information, and process information. The aforementioned date and time information can be obtained by using a mobile communication terminal to read the encrypted code, providing information about the date and time at which time. By using the date and time from the mobile communication terminal, direct input is eliminated, thus reducing input errors, lowering the burden of work management, and making the system easier for users to use. The aforementioned location information can be obtained by using a mobile communication terminal to access location information at the time the encrypted code is read. Specifically, the Global Positioning System (GPS) installed in the mobile communication terminal can be used, making it easy to acquire location information.

[0030] The aforementioned process information is transmitted to the management server by the person in charge regarding the current status and progress of their work. The person in charge selects or inputs process information displayed on the screen of the application on the mobile communication terminal, etc., and transmits it to the management server. Specifically, for delivered goods, this includes process information such as shipping, collection, transportation, sorting, and receiving. For waste and recycled resources, this includes process information such as on-site dismantling, sorting of waste, collection, transportation, unloading, receiving, storage, and processing.

[0031] Other management information may include: the name, address, telephone number, item name, number of packages, and delivery precautions for delivered goods; the name, address or location, and telephone number of the waste generator, transporter, storage operator, and processing operator (hereinafter collectively referred to as "generators, etc."); a management code individually assigned to each generator, etc.; a classification code assigned to each type and item of industrial waste, specially controlled industrial waste, and specified industrial waste; a hazardous substance code assigned to waste containing hazardous substances classified as specially controlled industrial waste; and remarks containing special notes such as volume, packaging, and processing method. For delivered goods, including the item name and precautions such as fragile items in the management information makes it easy to alert transporters. Similarly, for waste, including the type, item, and special notes in the management information facilitates transportation and intermediate / final processing operators.

[0032] [Image Information] Furthermore, the present invention may include image information captured by a camera function installed in a mobile communication terminal as activity information. The aforementioned image information is transmitted to the management server as activity information, along with the person in charge's information and management information, after the encryption code of the authentication card is read and the process information is entered, using the camera function of the person in charge's mobile communication terminal to capture an image of the object. By including image information in the activity information, the actual image of the object can be visually confirmed, further improving the accuracy, reliability, traceability, and evidentiary value of the activity information transmitted at each process.

[0033] The images transmitted as image information include still images and moving images. Moving images have the advantage of being easy for viewers to understand because they contain a large amount of information, while still images have the advantage of requiring less data capacity, although they can transmit less information. Among these, still images are preferred because they have a small transmission capacity and short transmission time. There is no limit to the number of images that can be taken; you should take and send as many as necessary for management. The image information is centrally managed on the management server as part of the activity information that makes up the timeline described later.

[0034] At demolition sites for houses and other buildings, it is sometimes necessary to photograph the interior and exterior of the house before demolition, either from a specific direction or of a specific object. In this case, the aforementioned direction or other arrangements are displayed as shooting items on the application, and after being selected on the screen, an image is taken. By associating the shooting items with the image information, there is no need to worry about forgetting to take necessary images. In other words, the person in charge selects demolition from the process information, selects the shooting items, takes an image, and sends it to the management server, so that the image information can be included in the activity information. This transmission can be done for each item as it is taken, or after all items have been photographed. Furthermore, by changing the display of items that have been photographed and items that have not been photographed, the risk of missing any images can be further reduced.

[0035] <Management Server> In this invention, the management server collects, stores, and centrally manages activity information transmitted by the person in charge in chronological order. Since the management server automatically stores the activity information transmitted by the person in charge in chronological order to create a timeline, no special work is required. The management server recording the activity information in chronological order constitutes the creation of the timeline. In the management server shown in Figure 1, the vertically stacked data indicates that activity information is being accumulated. The terms "Site 1" and "Site N," along with the white arrows, indicate that activity information from Site 1 to Site N is being accumulated in chronological order.

[0036] When an authorized person accesses the management server and requests to view the timeline, the management server returns the created timeline and informs them of the current status. This allows the requester to view the activity information of the person in charge and understand the current status of the subject. For security reasons, access to the aforementioned management server should be restricted to individuals who have registered their personal identification (ID) and password with the management server in advance, and it is preferable to require the ID and password when accessing the server. Those who can access the server include clients, staff, supervisors, site managers, and other individuals related to the object in question.

[0037] The aforementioned timeline is created for each person in charge. This makes it easy to understand when, where, which object, and to what stage the person in charge has completed their work, so that the person in charge of each stage does not need to create separate ledgers. Examples of the aforementioned ledgers include daily reports, reports, management slips, and management documents that record the day's work, transportation details, and construction and demolition work. Furthermore, the timeline is not limited to individual employees. It goes without saying that it can be used to broaden the scope of management beyond individual employees to include groups, teams, companies, entire corporate groups, or combinations of these.

[0038] The timeline may also include output and printing functions for formats such as Excel and PDF. This allows for management in both electronic and paper formats, enabling management tailored to the administrator's needs.

[0039] <Monitoring function> In this invention, the monitoring function is a function that checks the content of activity information sent to the management server and notifies or displays the result if the activity information deviates from the normal range. Specifically, in the case of activity information sent by the person in charge, inaccurate activity information may be sent to the management server due to human error. In such cases, the management server compares and checks the sent activity information with previously sent activity information, and if there is a possibility of error, it notifies or displays that fact.

[0040] Examples of error check items in the aforementioned monitoring function include differences in personnel, differences in numerical values ​​such as the number of items lifted and unloaded, differences in the type of object, differences in the destination, or failure to transmit activity information due to operational errors or forgetting to operate, but the present invention is not limited to these. Needless to say, all items that can normally be conceivable can be used as error check items, and they can be freely set as appropriate depending on the situation in which the present invention is applied.

[0041] The method of displaying the monitoring function is not particularly limited, and examples include displaying activity information containing errors in a different color on a mobile communication terminal or management server, adding a note indicating the presence of an error, emitting an alarm sound, or sending a separate notification to the mobile communication terminal or management server. Alternatively, methods such as directly contacting the administrator or person in charge of the management server via email may be adopted. A display method can be appropriately selected according to the situation to which the present invention is applied. Among these, it is preferable that activity information containing errors is displayed in a different color from other activity information without errors, so that the person in charge of the activity information can determine at a glance whether or not there is an error. Furthermore, it is particularly preferable to color-code the information by site, by person in charge, etc., so that it is possible to determine at what stage the error occurred.

[0042] Examples of terminals equipped with the aforementioned monitoring function include the same mobile communication terminals used by the person in charge. Among these, mobile communication terminals such as mobile phones, smartphones, tablet terminals, and laptop computers are preferred because they are lightweight, widely available, and easy for anyone to operate. Alternatively, the mobile communication terminal may be connected to an internet network, and monitoring may be performed within the network or in the cloud.

[0043] Figure 2 illustrates the case where inaccurate (error-filled) activity information is sent to the management server by the monitoring function of the present invention. As shown in Figure 2, first, the person in charge at Site 1 (source) sends activity information, including person in charge information, date and time information, location information, image information, etc., to the management server via a mobile communication terminal (initial entry). Upon receiving this, the management server records the activity information within the management server. Next, when the person in charge at Site 2 (intermediate) makes an inquiry or request regarding the activity information at Site 1, the management server responds by sending the recorded activity information to the person in charge. The person in charge at Site 2 refers to the transmitted activity information to confirm the target object and performs tasks such as receiving and unloading. When the person in charge performs the receiving or other work processes, activity information is sent to the management server via the mobile communication terminal of person in charge 2 (additional entry). The management server compares the activity information sent by the person in charge at Site 1 (initial entry) and the activity information sent by the person in charge at Site 2 (additional entry) using its monitoring function to check whether there are any errors in the activity information. At this time, if the data is confirmed to be correct, it is recorded in the management server. If the activity information is found to be incorrect, it is recorded in the management server as an activity with errors, with a different color than activity information without errors. This process is carried out up to site N (final) (completion), accumulating activity information and creating a timeline. The created timeline is checked for errors by the person in charge of managing the site, and edits are made as needed using the editing function described later. The person in charge of management only needs to check the activity information with errors, thus simplifying the verification process and reducing the time required for verification.

[0044] <Editing function> In the present invention, the editing function is a function that enables editing to correct errors in activity information discovered by the monitoring function. In the present invention, editing means one or more of the following actions: modification, deletion, and addition. While the entities that can edit errors may or may not be limited, it is preferable to limit those who can edit in order to enhance the reliability, traceability, and evidentiary value of the data against malicious editing. Specific examples of editors include on-site managers and supervisors, the person in charge of the management server and their managers, and supervisors. It is preferable that editors be able to edit using their own devices.

[0045] In this invention, it is crucial that an editing log is recorded when an error in activity information is edited from a terminal owned by the editor. Preferably, the editing log includes not only the edited content but also date and time information, editor information of the person who made the edit, and information about the edited item. This makes it immediately clear who edited which activity information, when, and to what extent, and is expected to have an effect in preventing unauthorized tampering. Specifically, when editing actions such as modification, deletion, or addition are performed on activity information in the management server, the edited activity information and the editing log (edited content) are linked and recorded in the management server. This improves the credibility and transparency of the data in the case of edits due to differences in numerical values, etc., and prevents unauthorized tampering, thereby increasing reliability, traceability, and evidentiary value. It is preferable that the linking is performed automatically within the management server in terms of improving reliability and evidentiary value.

[0046] Figure 3 is a schematic diagram of the second activity information management system of the present invention. In the activity information management system shown in Figure 3, the process is the same as the first activity information management system described with Figures 1 and 2 until editing logs are recorded using the editing function; therefore, a detailed explanation will be omitted.

[0047] <Tamper-proof function> A second feature of the activity information management system of the present invention is that, in addition to the monitoring and editing functions, it is equipped with a tamper-proof function that prevents anyone from editing the activity information and editing logs after a predetermined instruction has been given. By providing this tamper-proof function, reliability, traceability, and evidentiary value can be further improved. It is desirable that the tamper-proof function be activated when a predetermined instruction is given to the management server, in terms of ease of operation and speed. Examples of the prescribed instructions include actions and signatures indicating that inspection and acceptance testing have been completed. The entities that can give these prescribed instructions include the editor, their superior, or their supervisor.

[0048] Figure 4 is a flowchart illustrating the second activity information management system of the present invention. S1 is activity information sent by the person in charge and a timeline created by the management server. S2 is a monitoring function that checks for errors in the activity information and timeline. If an error is detected by the monitoring function, it is rejected in S3 and an error is displayed. S4 is an editing function that edits the error item. If edited using the editing function, the edited activity information and the editing log recording the edited content are linked. Then, the monitoring function S3 checks it again. If no errors are detected in the re-checked data, the verification process for that activity information is completed. S2 to S4 are repeated until no errors are detected in any activity information, and the verification process for that activity information is completed (S5). After the verification process for the activity information is completed, once the person with acceptance authority has completed the final check, it is processed as acceptance data (S6). The acceptance data that has undergone the above processing cannot be edited further due to the tamper-proof function.

[0049] Furthermore, the present invention can be suitably used in resource recycling in a circular economy. A circular economy is defined as "a society in which the generation of waste from products is suppressed, and when products become recyclable resources, their proper cyclical use is promoted, and for recyclable resources that are not used cyclically, proper disposal (disposal as waste (garbage, bulky waste, incinerator ash, sludge, human and animal waste, waste oil, waste acid, waste alkali, animal carcasses, and other pollutants or unwanted materials, whether solid or liquid; the same applies hereinafter)) is ensured, thereby suppressing the consumption of natural resources and reducing the burden on the environment as much as possible" (Article 2, Paragraph 1 of the Basic Act on Promotion of the Formation of a Circular Society). The aforementioned recyclable resources are, as described above, useful waste (Article 2, Paragraph 3 of the same Act). The aforementioned useful materials are those from which some value can be found that allows them to be used as resources. Figure 5 shows a schematic diagram of the application of the activity information management system of the present invention to recyclable resources, and Figure 6 is an explanatory diagram that shows the schematic diagram of resource recycling shown in Figure 5 in more detail. In Figure 6, the terms enclosed in squares and the arrows extending from them indicate situations where the activity information of the person in charge can be transmitted to the management server for management, while the terms enclosed in diamonds indicate branching points in resource recycling. In other words, by managing the activity information of the person in charge in a timeline at each stage, from raw materials to manufacturing, sales, and back to manufacturing as recycled material, it is possible to create a system that manages the activity information of the person in charge involved in recycled resources. One of the objectives of resource recycling is to return recycled resources to the manufacturer, but by using the activity information management system of the present invention, it becomes possible to manage the origin of recycled resources (which product the recycled material originated from). This has the advantage that the manufacturer can accurately grasp the origin of the recycled material and the value (brand) of the recycled material is guaranteed. [Industrial applicability]

[0050] The activity information management system of the present invention is suitably used for delivery items, mail, recyclable materials, products, waste, and recycled resources, but it can also be applied to other services such as home renovation, remodeling, or care services such as personal care, daily living assistance, and transportation assistance to medical appointments.
