Description

[Technical Field]

[0001] The present invention relates to a data management system, a data management method, and a data management program. [Background technology]

[0002] Data management systems such as cloud storage services implement the following functions to prevent and detect hacking and tampering of stored data. (1) Identity authentication: ID and password authentication, two-step authentication, etc. (2) Data encryption: Encryption using a key (3) Traceability: Recording the history of data updates and references

[0003] Here, the conventional technology assumes that the user himself / herself is mentally normal. However, with the conventional technology, even if the user himself / herself is in a mentally abnormal state (depression, dementia, etc.), if he / she passes the identity authentication, he / she can register, update, or delete data. For example, important information (such as a will) created by a user in a state of dementia can be stored as long as identity authentication is passed, even if the data does not reflect the user's correct intentions. In other words, conventional technology can protect stored information from hacking and tampering. However, it has the disadvantage of being unable to identify whether the stored information itself was created by a mentally normal user.

[0004] Data management systems such as cloud storage services are commonly used by businesses and individuals and often store important information. Therefore, future data management systems are likely to place emphasis on data authenticity in addition to data protection.

[0005] The inventors of this application have previously completed inventions relating to a brain information analysis device and a brain information mimicking computing device (Patent Document 1, etc.). These brain information analysis device and brain information mimicking computing device can objectively and statistically estimate what is good or bad for brain health and use it as an index of brain health (BHQ: Brain Healthcare Quotient) for the subject. BHQ is an index for brain health management and is calculated by analyzing brain image data obtained using magnetic resonance imaging (MRI). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 6739841 Summary of the Invention [Problem to be solved by the invention]

[0007] The data management system of the present invention aims to improve the disadvantages of the above-mentioned conventional examples, and in particular to improve the credibility of data stored in a data management system such as cloud storage. [Means for solving the problem]

[0008] To solve this problem, the data management system of the present invention, which allows an authenticated user to register, update, or delete data in the data storage unit, includes a first storage unit that pre-stores normal brain test criteria and an input unit that accepts input of a brain test identifier from the authenticated user. It also includes an acquisition unit that acquires brain test-related values ​​linked to the input brain test identifier from the second storage unit, and a determination unit that determines whether the acquired brain test-related values ​​satisfy the normal brain test criteria. Furthermore, the data management system of the present invention is configured to include an access processing unit that allows a user to register, update, or delete data in the data storage unit on the condition that the brain test-related values ​​satisfy the normal brain test criteria. [Effects of the Invention]

[0009] According to the present invention, data storage is permitted if the user's brain test-related values ​​meet the criteria for determining a normal brain, thereby improving the credibility of data stored in data management systems such as cloud storage. [Brief explanation of the drawings]

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in Figure 1, the data management system 10 includes a first memory unit 11, an input unit 12, an acquisition unit 13, a determination unit 14, an access processing unit 15, a display processing unit 16, a sharing processing unit 17, a user memory unit 18, and a data storage unit D. The input unit 12 accepts input of a brain examination identifier input from the authenticated user's user terminal 30. The first storage unit 11 stores in advance criteria for determining whether a brain is normal.

[0012] The data management system 10 is connected to a BHQ service system 20 via a network. The BHQ service system 20 includes a second recording unit 21 that records the brain test identifier input from the data management system 10. The second recording unit 21 then stores the brain test-related value linked to the input brain test identifier.

[0013] The acquisition unit 13 of the data management system 10 acquires the brain test related values ​​from the second storage unit 21 of the BHQ service system 20. Then, the determination unit 14 determines whether the acquired brain test related values ​​satisfy the brain normality determination criteria. Furthermore, the access processing unit 15 permits the user to register, update or delete data in the data storage unit D on the condition that the brain examination related values ​​satisfy the brain normality criteria.

[0014] Furthermore, the display processing unit 16 provides information to be displayed on a GUI (Graphical User Interface) of the user terminal 30. Furthermore, the sharing processing unit 17 sets other users with whom the data stored in the data storage unit D can be shared. The user storage unit 18 stores basic user information and a brain test identifier in association with each other for each user. The user basic information includes information necessary for login authentication of the user, such as the user ID and login password.

[0015] More specifically, in this embodiment, the second storage unit 21 stores a brain examination identifier and a brain examination-related value in association with each other. In this embodiment, the brain examination identifier is a unique identifier issued to a user each time the user undergoes a brain examination. In this embodiment, the brain test is a brain test using a brain information analysis device and a brain information mimicking computing device, which were mentioned in the Background Art section. In this application, this brain test is called a BHQ dock.

[0016] The brain test-related values ​​are values ​​related to the brain test that has been performed. In this embodiment, the brain test-related values ​​include BHQ values ​​obtained by a BHQ dock using a brain information analysis device and a brain information mimicking computing device. Furthermore, the brain examination related value includes information on the date of the BHQ medical checkup. The association between the brain examination identifier and the brain examination related value is registered in the second storage unit 21 every time the user undergoes the BHQ medical checkup. In this embodiment, the second storage unit 21 is managed by the BHQ service system 20.

[0017] Meanwhile, in this embodiment, the brain normality determination criteria stored in the first storage unit 11 are created based on the date of the BHQ medical checkup. That is, the brain normality determination criteria are based on whether the assessment date is within a predetermined period from the date of the BHQ medical checkup. The judgment unit 14 judges the user's brain condition to be normal (healthy) when JD+T≧TD is satisfied (corresponding to TD1 or TD2 in FIG. 6), where TD is the day of judgment, JD is the examination date, and T is the set fixed period of time. Here, the set fixed period of time T is the period during which the results of the BHQ dock examination are valid. The administrator of the data management system 10 can set and change the fixed period of time T from a management terminal (not shown).

[0018] The data storage unit D stores a user identifier, a data identifier, stored data, and sharing setting information in association with each other. The user identifier is identified by the input unit 12 authenticating the login of the user using the user basic information. The data identifier includes information on the type of file or folder and its path on the database. The stored data refers to the entity of data managed by the data management system 10. The stored data includes information on important documents, such as wills, land titles, and insurance policies.

[0019] The sharing setting information includes the user identifiers of other users (sharers) who are permitted by the user to share the stored data, and the operations permitted to the sharers. The sharing setting information is registered and changed by the sharing processing unit 17. For example, the sharing processing unit 17 sets Lawyer A and Lawyer B as co-owners, and then allows Lawyer A to upload and download wills and land title deeds. The sharing processing unit 17 also enables the setting and modification of sharing, such as allowing Lawyer B to download only land title deeds and insurance policies. In this embodiment, the data management system 10 provides a cloud storage service function, and the data storage unit D is managed by the cloud storage service function.

[0020] 2 is a hardware schematic diagram of this embodiment. The data management system 10, the BHQ service system 20, and the user terminal 30 are connected to a computer network such as the Internet and communicate with each other. For one data management system 10, there are multiple users of the data management system 10 and multiple user terminals 30.

[0021] The data management system 10 includes components of a typical server system, i.e., multiple communication devices for communicating with the BHQ service system 20 and the user terminals 30, multiple mass storage devices, and multiple processors.

[0022] The data management system 10 realizes various operations by executing predetermined programs through cooperation between multiple processors. The operations of the input unit 12, acquisition unit 13, determination unit 14, access processing unit 15, display processing unit 16, and sharing processing unit 17 shown in Fig. 1 are realized by the processors of the data management system 10 executing predetermined programs. Furthermore, the first memory unit 11, user memory unit 18, and data storage unit D shown in Fig. 1 are each provided in a memory area of ​​a mass storage device of the data management system 10.

[0023] Similarly, the BHQ service system 20 also has the components of a general server system. The BHQ service system 20 has a plurality of communication devices for communicating with the data management system 10 and the user terminal 30, a plurality of large-capacity storage devices, and a plurality of processors. The BHQ service system 20 realizes various operations by the cooperation of the plurality of processors and execution of predetermined programs. The BHQ service system 20 performs the functions of the brain information analysis device and brain information mimicking arithmetic device described above by the processors executing the predetermined programs.

[0024] As a result, the BHQ service system 20 calculates the BHQ score of the examinee who has undergone the BHQ dock. The BHQ service system 20 also associates the brain test identifier issued to the examinee with brain test-related values ​​including the BHQ score and the examination date, and stores them in the second storage unit 21. The second storage unit 21 is provided in a storage area of ​​a mass storage device of the BHQ service system 20.

[0025] On the other hand, the user terminal 30 includes components of a typical computer device, such as an input device, a display device, a storage device, a communication device, and a processor. The input device is a keyboard, a touch panel, etc. The display device is an LCD monitor, a touch panel, etc. The storage device includes a temporary storage device and a large-capacity storage device. The communication device is a NIC (Network Interface Card) or the like that communicates with the data management system 10 and the BHQ service system 20. The processor executes predetermined programs to realize various operations.

[0026] 3 is a flowchart showing the operation of this embodiment. First, a user of the data utilization system 10 undergoes a BHQ dock as a brain test (S21). The BHQ service system 20 issues a brain test identifier to the user who has undergone the BHQ dock (S22). The user obtains the issued brain test identifier in writing, by email, or the like. The BHQ service system 20 associates the issued brain test identifier with the BHQ value and the examination date included in the test results of the BHQ dock, and stores them in the second storage unit 21 (S23).

[0027] A user of the data management system 10 logs in to the data management system 10. The data management system 10 authenticates the user by comparing the login authentication information received from the user terminal 30 with the user basic information, and permits the user to log in to the data management system 10. At this time, the data management system 10 identifies the user identifier of the logged-in user (S11). Thereafter, the input unit 12 acquires the brain examination identifier input to the user terminal 30, and associates the user identifier included in the user basic information with the brain examination identifier, and registers them in the user storage unit 18 (S12).

[0028] Thereafter, the data management system 10 receives an access request to the data storage unit D from the user terminal 30 (S13). There are four types of access requests: data registration, update, deletion, or reference. The access processing unit 15 of the data management system 10 determines whether the access request is one of the four types: data registration, update, deletion, or reference (S14). Then, in step S14, if the access request is not data registration, update, or deletion (NO in S14), the data management system 10 performs a reference process for the requested data (S15). The data reference process in step S15 reads the requested stored data from the data storage unit D and sends it to the user terminal 30.

[0029] On the other hand, if the access request is for data registration, update, or deletion (YES in S14), the acquisition unit 13 reads out the brain test identifier linked to the user identifier of the user who requested the access from the user storage unit 18. Then, the acquisition unit 13 notifies the BHQ service system 20 of the brain test identifier, and requests the BHQ service system 20 for the brain test-related value linked to the brain test identifier. Upon receiving this request, the BHQ service system 20 reads out the brain test related value linked to the brain test identifier from the second storage unit 21 and transmits it to the requesting data management system 10. The acquisition unit 14 acquires the brain test related value linked to the brain test identifier from the BHQ service system 20, and passes the information on the examination date included in the brain test related value to the determination unit 14 (S16).

[0030] The judgment unit 14 refers to the normal brain judgment criteria stored in the first storage unit 11 and judges whether the date of examination satisfies the normal brain judgment criteria (S17). If a certain period has passed since the date of examination and the date does not satisfy the normal brain judgment criteria (NO in S17), the access processing unit 15 executes processing to disable data registration, update, and deletion (S19). On the other hand, if the certain period has passed since the date of examination and the examination date satisfies the normal brain judgment criteria (YES in S17), the access processing unit 15 executes data registration, update, or deletion processing requested by the user terminal 30 to the data storage unit D (S18).

[0031] Fig. 4 is a flowchart showing the operation of the display processing unit 16. Fig. 5 shows a GUI that the display processing unit 16 displays on the display device of the user terminal 30. The user can request data registration, update, or deletion from the data management system 10 by operating the GUI shown in Fig. 5. The GUI shown in Fig. 5 includes a first display unit 31 that displays the status of the brain examination, and a second display unit 32 that displays whether data registration, update, or deletion is possible. The displays on the first display unit 31 and the second display unit 32 change as the display processing unit 16 executes the processing of Fig. 4. The second display unit 32 also serves as a request button (request operator) for data registration, update, or deletion.

[0032] In FIG. 4, the display processing unit 16 first determines whether the day displayed by the GUI is within a certain period (valid period) from the examination date (S31). The display processing unit 16 uses TD for the current day, JD for the examination date, and T for the certain period (valid period). If JD + T < TD, it determines that the current day has exceeded the certain period from the examination date (NO in S31: corresponding to TD3 in FIG. 6). In this case, the display processing unit 16 displays a message on the first display unit 31 requesting a new brain examination, and displays a message on the second display unit 32 indicating that data registration, update, or deletion is not allowed (S32). At this time, the display processing unit 16 invalidates the second display unit 32 so that it does not function as a request button. Here, the certain period T is the same as the certain period T shown in the explanation of the brain normal determination criteria.

[0033] On the other hand, in step S31, if JD + T ≥ TD (YES in S31), the current day is within a certain period (valid period) from the examination date (corresponding to TD1 or TD2 in FIG. 6). In this case, the display processing unit 16 determines whether the current day is within the attention period near the expiration date (S33). Using TD for the current day, JD for the examination date, T for the valid period, and R for the attention period, if JD + T - R ≤ TD, the display processing unit 16 determines that the current day has entered the attention period near the expiration date (YES in S33: corresponding to TD2 in FIG. 6). In this case, the display processing unit 16 displays a message on the first display unit 31 recommending a new brain examination, and the second display unit 32 displays a message indicating that data registration, update, or deletion is possible (S34). At this time, the display processing unit 16 validates the second display unit 32 so that it functions as a request button.

[0034] On the other hand, if JD + T - R > TD, the display processing unit 16 determines that the current day has not entered the attention period (YES in S33: corresponding to TD1 in FIG. 6). In this case, the display processing unit 16 displays a message on the first display unit 31 indicating that a brain examination is valid, and the second display unit 32 displays a message indicating that data registration, update, or deletion is possible (S35). At this time, the display processing unit 16 validates the second display unit 32 so that it functions as a request button.

[0035] According to the embodiment described above, if the user's brain test-related values ​​satisfy the brain normality criteria, data storage is permitted, thereby improving the credibility of data stored in cloud storage.

[0036] In particular, the brain test-related value is the date of the brain test, and the criterion for determining whether the brain is normal is whether it is within a certain period from the date of the test, so that the determination of whether the brain is normal can be made by simple processing with a relatively low load.

[0037] In addition, the display processing unit 16 enables or disables the request buttons for data registration, update, or deletion displayed on the user terminal 30 depending on whether the brain normality judgment criteria are met, so that the user can quickly understand whether their own brain normality judgment criteria are met.

[0038] Next, a modification of the above embodiment will be described. The brain test-related value may be an index value representing the brain's health state. In this case, the brain normality criterion may be that the index value indicates a brain normality when compared with a preset threshold. In particular, the brain test-related value may be a BHQ value. In this case, as shown in FIG. 3, the determination unit 14 refers to the brain normality criterion stored in the first storage unit 11 and determines whether the BHQ value satisfies the brain normality criterion (S17). That is, the determination unit 14 determines whether the BHQ value indicates a brain normality when compared with the preset threshold.

[0039] 3, if the brain normality criterion is not met, the access processing unit 15 executes processing to prohibit data registration, update, and deletion (S19). On the other hand, if the brain normality criterion is met, the access processing unit 15 executes data registration, update, or deletion processing requested by the user terminal 30 on the data storage unit D (S18). The other configurations are the same as those of the above-mentioned embodiment. This also achieves the same effects as the above-mentioned embodiment, and makes it possible to determine whether to permit data registration, update, or deletion based on a relatively highly accurate brain normality determination using the BHQ value.

[0040] Here, the scope of the present invention is not limited to the above-described embodiments, but includes all aspects that do not deviate from the scope of the invention as set forth in the claims. For example, the criteria for determining brain normality are not limited to those based on the date of examination. The second storage unit 21 is not limited to those managed by the BHQ service system 20. The data management system 10 is not limited to cloud storage. Various database structures are conceivable for linking one piece of information with other pieces of information. As long as the necessary information is ultimately linked, the database structure is not limited to the above-described embodiments. [Explanation of symbols]
