　しかりながら、従来の生体情報管理システムである検診システムでは、検査結果を、検体採取キットのキット識別情報とリンクさせて蓄積し、キット識別情報に基づいて読み出しているため、キット識別情報を有するものとして被験者である利用者が特定されてしまうという問題がある。 However, in a screening system that is a conventional biological information management system, the test results are stored in a linked manner with the kit identification information of the sample collection kit, and are read based on the kit identification information. There is a problem that the user who is the subject is specified.
　さらに、被験者としての利用者のみならず、キット識別情報を有する者であれば、キット識別情報により検査結果へ自由にアクセスができてしまうという問題がある。 Furthermore, not only a user as a subject but also a person having kit identification information has a problem that the test result can be freely accessed by the kit identification information.
　以上の事情に鑑みて、本発明は、利用者が特定されることを防止しつつ、生体情報へのアクセスを制限することができる生体情報管理システムを提供することを目的とする。 In view of the above circumstances, an object of the present invention is to provide a biological information management system capable of restricting access to biological information while preventing a user from being specified.
　第１発明の生体情報管理システムは、利用者の生体情報を記憶保持する生体情報管理システムであって、
　前記利用者側に設けられた利用者端末と、
　前記利用者端末とネットワーク接続された管理システム本体と、
　前記管理システム本体とネットワーク接続され、前記利用者の生体情報を記憶保持する分散型台帳システムと

　前記利用者端末から前記管理システム本体にアクセスされることにより、暗号鍵と復号鍵とが生成され、該暗号鍵が該管理システム本体に記憶されると共に、該復号鍵が該利用者端末に記憶され、
　前記管理システム本体は、利用者の生体情報を前記暗号鍵に基づいて暗号化し、暗号化した生体情報を前記分散型台帳システムに記憶保持させると共に、該分散型台帳システムから読み出した暗号化された生体情報を、前記利用者端末から取得した復号鍵により復号することを特徴とする。 The biological information management system of the first invention is a biological information management system that stores and holds the biological information of the user,
A user terminal provided on the user side;
A management system main body connected to the user terminal via a network;

By accessing the management system main body from the user terminal, an encryption key and a decryption key are generated, the encryption key is stored in the management system main body, and the decryption key is stored in the user terminal. And
The management system main body encrypts the user's biometric information based on the encryption key, stores the encrypted biometric information in the distributed ledger system, and stores the encrypted biometric information read from the distributed ledger system. The biometric information is decrypted with a decryption key acquired from the user terminal.
　第１発明の生体情報管理システムによれば、生体情報の記憶保存に際して、予め利用者端末から管理システム本体へのアクセスにより、暗号鍵と復号鍵とが生成され、暗号鍵が管理システム本体に記憶されると共に、復号鍵が該利用者端末に記憶される。 According to the biometric information management system of the first invention, when storing and storing biometric information, an encryption key and a decryption key are generated in advance by accessing the management system body from the user terminal, and the encryption key is stored in the management system body. At the same time, the decryption key is stored in the user terminal.
　そのため、復号鍵は利用者端末に存在しているに過ぎず、復号鍵により被験者である利用者が直接特定されることがない。 Therefore, the decryption key exists only in the user terminal, and the user who is the subject is not directly specified by the decryption key.
　また、利用者の生体情報は管理システム本体の暗号鍵に基づいて暗号化され、暗号化された生体情報が分散型台帳システムに記憶保持させる。さらに、分散型台帳システムから読み出した暗号化された生体情報は、利用者端末から取得した復号鍵により復号されることから、生体情報へのアクセスが暗号鍵と復号鍵により制限される。 Also, the user's biometric information is encrypted based on the encryption key of the management system main body, and the encrypted biometric information is stored and held in the distributed ledger system. Furthermore, since the encrypted biometric information read from the distributed ledger system is decrypted with the decryption key acquired from the user terminal, access to the biometric information is restricted by the encryption key and the decryption key.
　このように第１発明の生体情報管理システムによれば、利用者が特定されることを防止しつつ、生体情報へのアクセスを制限することができる。 Thus, according to the biological information management system of the first invention, access to the biological information can be restricted while preventing the user from being specified.

The encryption key and the decryption key generated by accessing the management system main body from the user terminal are associated with the unique identification ID,
In the management system body, the biometric information measured via the measurement kit is encrypted based on the encryption key via the unique identification ID and stored and held in the distributed ledger system, The encrypted biometric information read from the distributed ledger system through the unique identification ID is decrypted with the decryption key acquired from the user terminal.
　第２発明の生体情報管理システムによれば、暗号鍵と復号鍵とが測定キットの固有識別ＩＤと紐付けされることにより、測定結果である生体情報を固有識別ＩＤに基づいて暗号鍵による暗号化をすることができると共に、固有識別ＩＤと紐付いた復号鍵を有する利用者端末のみに生体情報へのアクセスを可能とすることができる。 According to the biometric information management system of the second invention, the encryption key and the decryption key are associated with the unique identification ID of the measurement kit, whereby the biometric information that is the measurement result is encrypted using the encryption key based on the unique identification ID. In addition, only the user terminal having the decryption key associated with the unique identification ID can be made accessible to the biometric information.
　このように、第２発明の生体情報管理システムによれば、利用者が特定されることを防止しつつ、生体情報へのアクセスを制限することが具体的に実現できる。 Thus, according to the biological information management system of the second aspect of the present invention, it is specifically possible to restrict access to biological information while preventing a user from being specified.
　第３発明の生体情報管理システムは、第２発明において、
　前記生体情報の測定キットは、唾液癌マーカー検査キットであって、
　前記生体情報は、前記唾液癌マーカー検査キットにより採取された唾液のサイトカイン値であり、

The biological information is a cytokine value of saliva collected by the salivary cancer marker test kit,
The management system main body provides a cancer risk evaluation value based on the cytokine value to the user terminal by obtaining a decryption key from the user terminal.
　第３発明の生体情報管理システムによれば、生体情報の測定キットは、唾液癌マーカー検査キットの場合に好適であり、この場合には、生体情報である唾液サイトカイン値へのアクセスに加えて、癌リスク評価値の利用者端末への提供を復号鍵によりアクセス制限することができる。 According to the biological information management system of the third invention, the biological information measurement kit is suitable for a salivary cancer marker test kit, and in this case, in addition to accessing the salivary cytokine value, which is biological information, The provision of the cancer risk evaluation value to the user terminal can be restricted by the decryption key.

　次に、図２～図５を参照して、以上のように構成された生体情報管理システムの処理内容について説明する。 Next, processing contents of the biological information management system configured as described above will be described with reference to FIGS.
　まず、図２を参照して鍵ペアの生成処理について説明する。 First, the key pair generation process will be described with reference to FIG.
　図２において、予め、唾液癌マーカー検査キットに付された固有識別ＩＤとしての機能を有するＱＲコードやシリアルナンバーを読み取ることにより、利用者端末１から管理システム本体２へのアクセスにより利用者端末１が管理システム２との間でＷｅｂアプリの利用が可能となると、トップ画面への利用者のアクセスにより（ＳＴＥＰ１１１／図２）、暗号鍵と復号鍵の鍵ペアの生成がされる（ＳＴＥＰ１１２／図２）。 In FIG. 2, the user terminal 1 is accessed by accessing the management system body 2 from the user terminal 1 by reading a QR code or serial number having a function as a unique identification ID attached to the salivary cancer marker test kit in advance. When the web application can be used with the management system 2, the key pair of the encryption key and the decryption key is generated by the user's access to the top screen (STEP 111 / FIG. 2) (STEP 112 / FIG. 2).
　ここで、暗号鍵と復号鍵の鍵ペアは、それぞれ唾液癌マーカー検査キットに付された固有識別ＩＤに紐付けされる。 Here, the key pair of the encryption key and the decryption key is associated with a unique identification ID attached to each salivary cancer marker test kit.
　そして、鍵ペアができたか否かが判断され（ＳＴＥＰ１１３／図２）、鍵ペアの生成ができない場合には（ＳＴＥＰ１１３／図２でＮＯ）、エラー出力がされる。 Then, it is determined whether or not a key pair has been made (STEP 113 / FIG. 2), and if a key pair cannot be generated (NO in STEP 113 / FIG. 2), an error is output.
　一方、鍵ペアが生成できている場合には（ＳＴＥＰ１１３／図２でＹＥＳ）、暗号鍵が管理システム本体２に送信されて管理システム本体２に保存されると共に（ＳＴＥＰ２１１／図２）、復号鍵が利用者端末１に保存される（ＳＴＥＰ１１５）。 On the other hand, if the key pair has been generated (STEP 113 / YES in FIG. 2), the encryption key is transmitted to the management system body 2 and stored in the management system body 2 (STEP 211 / FIG. 2), and the decryption key Is stored in the user terminal 1 (STEP 115).
　次に、図３を参照して、唾液ＩＤのメタデータの登録処理について説明する。 Next, the registration process of saliva ID metadata will be described with reference to FIG.
　まず、利用者が唾液癌マーカー検査キットにより唾液の採取を行い、例えば、採取管に付された唾液ＩＤのＱＲコードを利用者端末１を介して読み取りを行うと（ＳＴＥＰ１２１／図３）、ＱＲコードが正しく読み取れたか判定される（ＳＴＥＰ１２２／図３）。 First, when a user collects saliva using a salivary cancer marker test kit and reads, for example, a QR code of saliva ID attached to a collection tube via the user terminal 1 (STEP 121 / FIG. 3), QR It is determined whether the code has been read correctly (STEP 122 / FIG. 3).
　そして、ＱＲコードが正しく読み取れていない場合には（ＳＴＥＰ１２２でＮＯ／図３）、エラー出力がなされる（ＳＴＥＰ１２３／図３）。 If the QR code is not read correctly (NO in STEP 122 / FIG. 3), an error is output (STEP 123 / FIG. 3).
　一方、ＱＲコードが正しく読み取れている場合には（ＳＴＥＰ１２２でＹＥＳ／図３）、問診事項の入力画面が表示されて（ＳＴＥＰ１２４／図３）、回答された問診事項が管理システム本体２に送信されて、対象唾液ＩＤのメタデータの登録がなされる（ＳＴＥＰ２２１／図３）。 On the other hand, if the QR code is correctly read (YES in STEP 122 / FIG. 3), an inquiry item input screen is displayed (STEP 124 / FIG. 3), and the answered inquiry item is transmitted to the management system main body 2. Thus, the metadata of the target saliva ID is registered (STEP 221 / FIG. 3).
　なお、ここで採取管に付された唾液ＩＤのＱＲコードは、唾液癌マーカー検査キットに付された固有識別ＩＤとしての機能を有するＱＲコードやシリアルナンバーと基本的に同一であるが、例えば、１つの唾液癌マーカー検査キットに対して複数の採取管があるような場合には、別のものであってもよい。 The QR code of saliva ID attached to the collection tube here is basically the same as the QR code or serial number having a function as a unique identification ID attached to the salivary cancer marker test kit. In the case where there are a plurality of collection tubes for one salivary cancer marker test kit, another one may be used.
　なお、固有識別ＩＤと唾液ＩＤが同一の場合には、前述の暗号鍵および復号鍵との紐付けがそのまま維持される。一方、固有識別ＩＤに対して複数の唾液ＩＤがある場合には、予め固有識別ＩＤと複数の唾液ＩＤが紐付けされ、前述の暗号鍵および復号鍵との紐付けが、固有識別ＩＤを介して唾液ＩＤにも紐付けされる。なお、この場合、固有識別ＩＤは、利用者端末１の識別ＩＤに適宜置き換えられることが好ましい。利用者が唾液癌マーカー検査キットを複数回購入した場合、それぞれに同梱される採取管の唾液ＩＤと利用者とを紐づける必要があるからである。 In addition, when the unique identification ID and saliva ID are the same, the association with the encryption key and the decryption key is maintained as it is. On the other hand, when there are a plurality of saliva IDs with respect to the unique identification ID, the unique identification ID and the plurality of saliva IDs are associated in advance, and the association between the encryption key and the decryption key is performed via the unique identification ID. Also associated with saliva ID. In this case, it is preferable that the unique identification ID is appropriately replaced with the identification ID of the user terminal 1. This is because when a user purchases a salivary cancer marker test kit a plurality of times, it is necessary to associate the saliva ID of the collection tube bundled with each user with the user.
　次に、図４を参照して、唾液ＩＤのサイトカインデータの登録および癌リスク評価結果の作成処理について説明する。 Next, with reference to FIG. 4, registration of cytokine data of saliva ID and creation processing of a cancer risk evaluation result will be described.
　予め、利用者が唾液癌マーカー検査キットにより唾液の採取った採取管を、検査機関に郵送すると、検査機関により当該唾液のサイトカインの分析がなされる。 When a user previously mails a collection tube from which saliva has been collected using a salivary cancer marker test kit to a testing organization, the testing organization analyzes the cytokine of the saliva.
　ここで、サイトカインの分析結果は、管理システム本体２に提供され、唾液ＩＤで特定されるサイトカインの分析結果を管理システム本体２が取得する（ＳＴＥＰ２３１／図４）。 Here, the analysis result of the cytokine is provided to the management system main body 2, and the management system main body 2 acquires the analysis result of the cytokine specified by the saliva ID (STEP 231 / FIG. 4).
　そして、管理システム本体２は、取得した対象唾液ＩＤのサイトカインデータを固有識別ＩＤに基づいて暗号鍵を特定し、かかる暗号鍵でサイトカインデータを暗号化した上で、分散型台帳システム３に登録し、分散型台帳システム３に記憶保存させる（ＳＴＥＰ３３１／図４）。 Then, the management system body 2 specifies the encryption key of the acquired cytokine data of the target saliva ID based on the unique identification ID, encrypts the cytokine data with the encryption key, and registers it in the distributed ledger system 3. Then, it is stored and stored in the distributed ledger system 3 (STEP 331 / FIG. 4).
　さらに、管理システム本体２は、取得した対象唾液ＩＤのサイトカインデータに基づく癌リスク評価結果の作成を行い、作成された癌リスク評価結果を暗号鍵で暗号化した上で当該管理システム本体２に記憶保存する（ＳＴＥＰ２３２／図４）。 Further, the management system main body 2 creates a cancer risk evaluation result based on the acquired cytokine data of the target saliva ID, encrypts the created cancer risk evaluation result with an encryption key, and stores it in the management system main body 2 Save (STEP232 / FIG. 4).
　次に、図５を参照して、癌リスク評価結果の利用者への提供処理について説明する。 Next, with reference to FIG. 5, a process for providing the cancer risk evaluation result to the user will be described.
　まず、利用者が利用者端末１を操作して、評価結果表示画面へアクセスすると（ＳＴＥＰ１４１／図５）、管理システム本体２が対象唾液ＩＤのサイトカインデータを、唾液ＩＤ（固有識別ＩＤ）に基づいて、分散型台帳システム３から取得する（ＳＴＥＰ２４１／図５）。 First, when the user operates the user terminal 1 to access the evaluation result display screen (STEP 141 / FIG. 5), the management system main body 2 uses the saliva ID (unique identification ID) based on the cytokine data of the target saliva ID. And obtained from the distributed ledger system 3 (STEP 241 / FIG. 5).
　次いで、管理システム本体２は、対象唾液ＩＤの癌リスク評価結果を、唾液ＩＤ（固有識別ＩＤ）に基づいて、管理システム本体２内から取得する（ＳＴＥＰ２４２／図５）。 Next, the management system main body 2 acquires the cancer risk evaluation result of the target saliva ID from the management system main body 2 based on the saliva ID (unique identification ID) (STEP 242 / FIG. 5).
　ここで、ＳＴＥＰ２４１およびＳＴＥＰ２４２で取得した対象唾液ＩＤのサイトカインデータおよび癌リスク評価結果は、暗号鍵より暗号化された状態となっている。 Here, the cytokine data and the cancer risk evaluation result of the target saliva ID acquired in STEP 241 and STEP 242 are encrypted with the encryption key.
　そこで、当該暗号鍵と鍵ペアを成す復号鍵を利用者端末１からの送信により（ＳＴＥＰ１４２／図５）、取得できたか判定する（ＳＴＥＰ２４３／図５）。 Therefore, it is determined whether or not a decryption key that forms a key pair with the encryption key has been acquired by transmission from the user terminal 1 (STEP 142 / FIG. 5) (STEP 243 / FIG. 5).
　そして、復号鍵を取得できない場合には（ＳＴＥＰ２４３でＮＯ／図５）、利用者端末１に対してエラー出力を行い（ＳＴＥＰ１４３／図５）、復号鍵を取得できた場合には（ＳＴＥＰ２４３でＹＥＳ／図５）、復号鍵によりサイトカインデータおよび癌リスク評価結果を復号した上で、利用者端末１に送信して表示させる（ＳＴＥＰ１４４／図５）。 If the decryption key cannot be obtained (NO in STEP 243 / FIG. 5), an error is output to the user terminal 1 (STEP 143 / FIG. 5). If the decryption key can be obtained (YES in STEP 243). / FIG. 5), the cytokine data and the cancer risk evaluation result are decrypted with the decryption key, and then transmitted to the user terminal 1 for display (STEP 144 / FIG. 5).
　以上が本実施形態の生体情報管理システムの構成および処理内容であり、かかる生体情報管理システムによれば、生体情報であるサイトカインデータの記憶保存に際して、予め利用者端末１から管理システム本体２へのアクセスにより、暗号鍵と復号鍵とが生成され、暗号鍵が管理システム本体２に記憶されると共に、復号鍵が該利用者端末１に記憶される。 The above is the configuration and processing contents of the biological information management system of the present embodiment. According to such a biological information management system, when storing and storing cytokine data, which is biological information, from the user terminal 1 to the management system body 2 in advance. By the access, an encryption key and a decryption key are generated, the encryption key is stored in the management system main body 2, and the decryption key is stored in the user terminal 1.
　そのため、復号鍵は利用者端末１に存在しているに過ぎず、復号鍵により被験者である利用者が直接特定されることがない。 Therefore, the decryption key exists only in the user terminal 1, and the user who is the subject is not directly specified by the decryption key.
　また、利用者の生体情報であるサイトカインデータは、管理システム本体２の暗号鍵に基づいて暗号化され、暗号化されたサイトカインデータが分散型台帳システム３に記憶保持させる。さらに、分散型台帳システム３から読み出した暗号化されたサイトカインデータは、利用者端末１から取得した復号鍵により復号されることから、生体情報へのアクセスが暗号鍵と復号鍵により制限される。 Further, the cytokine data, which is the user's biometric information, is encrypted based on the encryption key of the management system main body 2, and the encrypted cytokine data is stored and held in the distributed ledger system 3. Furthermore, since the encrypted cytokine data read from the distributed ledger system 3 is decrypted with the decryption key acquired from the user terminal 1, access to the biometric information is restricted by the encryption key and the decryption key.
　さらに、暗号鍵と復号鍵とが測定キットである唾液癌マーカー検査キットの固有識別ＩＤ（唾液ＩＤ）と紐付けされることにより、測定結果であるサイトカインデータを固有識別ＩＤに基づいて暗号鍵による暗号化をすることができると共に、固有識別ＩＤと紐付いた復号鍵を有する利用者端末のみに生体情報へのアクセスを可能とすることができる。 Further, the encryption key and the decryption key are linked to the unique identification ID (saliva ID) of the salivary cancer marker test kit that is the measurement kit, whereby the cytokine data that is the measurement result is expressed by the encryption key based on the unique identification ID. Encryption can be performed, and only the user terminal having the decryption key associated with the unique identification ID can access the biometric information.
　このように、本実施形態の生体情報管理システムによれば、利用者が特定されることを防止しつつ、生体情報へのアクセスを制限することができる。 As described above, according to the biological information management system of this embodiment, access to biological information can be restricted while preventing a user from being specified.
　なお、本実施形態では、生体情報管理システムとして、生体情報の測定キットである唾液癌マーカー検査キットを用いる場合について説明したが、これに限定されるものではなく、その他の検査キット（大腸癌検査キット）や、検査キット以外の生体情報計測機器（血圧計や活動量計等）であってもよい。 In this embodiment, the case where a salivary cancer marker test kit, which is a biometric information measurement kit, is used as the biometric information management system is described. However, the present invention is not limited to this, and other test kits (colorectal cancer test) are used. Kit) or biological information measuring equipment (such as a blood pressure monitor or activity meter) other than the test kit.
　この場合、生体情報（検査で指標とされるデータ値や計測値）や（必要に応じて）これらに基づく評価結果が、暗号鍵により暗号化された上で管理システム本体２から分散型台帳システム３で記憶保存されると共に、分散型台帳システム３から読みだされた生体情報や評価結果は、利用者端末１の復号鍵により復号されて管理システム本体２から利用者端末１に提供される。 In this case, the biometric information (data values and measurement values used as indices in the examination) and evaluation results based on these (if necessary) are encrypted from the management key 2 and distributed to the ledger system. The biometric information and the evaluation result read out from the distributed ledger system 3 are decrypted by the decryption key of the user terminal 1 and provided to the user terminal 1 from the management system main body 2.
