According to an embodiment, each node that owns the blockchain can share and store the hash value of the next node. That is, the Nth node stores the hash value (Hash N-1) of the N-1th node, the N-1th node stores the hash value (Hash N-2) of the N-2th node, and the second The node may store the hash value (Hash 1) of the first node, and the first node may store the hash value (Hash 0) of the management node that is the first original node.

Each node may be a hospital that stores and manages individual medical record data and prescription data. As a hospital, each node can store medical records data, prescription data, and surgery data of the hospital, and hash data on medical records of other hospitals.

In the event of an emergency, data on medical records of other hospitals may be received from a personal health record platform management server or a user (ie, patient) terminal. The received data can be verified for integrity using the stored hash data. When new data is stored for each node with a blockchain, a block can be created and the hash data of the generated data can be shared with other nodes.

According to another embodiment, each node may be, for example, an emergency medical doctor or an emergency rescue team.

5 is a conceptual diagram illustrating a first information sharing method of a method of operating a cPHR service based on a block chain according to an embodiment of the present invention.

Referring to FIG. 5, in the method of operating a cPHR service based on a block chain according to an embodiment of the present invention, a first information sharing method can be identified, and more specifically, an information sharing method that can be performed at normal times can be identified. .

Specifically, the user may activate the sharing function through the execution of the application 510 in the terminal. Basically, the application can be executed by touching an icon displayed on the display of the terminal, but in some cases, it is possible to shake the terminal more than a predetermined number of times or swipe a specific area to execute the application.

This is because the application can be quickly executed by shaking the terminal or swiping a specific area of the display rather than finding and executing the cPHR application icon on the complex screen displayed when the terminal user is in an emergency situation.

Next, users can choose which data to share. In normal cases, My cPHR can be selected, and in case of an emergency, Emergency Summary can be selected. The information sharing method in case of an emergency will be described in detail in FIG. 6.

When the user selects My cPHR, the approval process 520 may pass, and My cPHR information may be shared from the user terminal to the medical personnel or guardian's terminal. In order to verify the user's identity, it is possible to approve using a fingerprint or password method, and in some cases, it is possible to use methods such as iris or face recognition.

When the person is authenticated through the above method, a terminal of a medical person or guardian to be shared may be set to share 530 personal health records online. The personal health record of the user (or patient) may be transmitted from the cPHR platform server to the terminal of a medical practitioner or guardian.

6 is a conceptual diagram illustrating a second information sharing method of a method of operating a cPHR service based on a block chain according to an embodiment of the present invention.

Referring to FIG. 6, in the method of operating a cPHR service based on a block chain according to an embodiment of the present invention, a second information sharing method can be identified, and in more detail, information sharing that can be performed in case of an emergency situation occurs. You can check the method.

The method of executing the application 610 in the terminal may be the same as the usual method of executing the application. However, according to an embodiment, a method of providing information in another emergency situation may be provided differently from a method of providing information in an ordinary way. When the Emergency Summary is selected as the shared data, the step 620 of authenticating the identity of the emergency medical service provider may be performed.

Specifically, after an emergency medical provider such as an emergency crew completes authentication through fingerprint recognition or password authentication in the terminal, the emergency patient's emergency summary may be received (630) by tagging with the user terminal of the emergency patient.

For example, when patient X is collapsed due to a sudden cardiac arrest, the paramedic who has received a report and dispatched runs the cPHR application on the paramedic's terminal, selects Emergency Summary, and performs fingerprint authentication. After that, the emergency summary information can be received from the terminal of patient X by tagging the terminal of the paramedic and the terminal of patient X.

Therefore, it is possible to check the disease, etc. that Patient X usually has and take it into account to perform first aid.

Referring to FIG. 12, a second configuration of a method for operating a cPHR service based on a block chain according to an embodiment of the present invention is described, and in more detail, a life log is generated during the process of interlocking between individual members, hospitals, and cPHR services. You can see how it is done and how the caregiver is monitored.

The cPHR service according to an embodiment of the present invention is performed based on a cPHR system to be described later.

The cPHR system according to an embodiment of the present invention connects the subject of creating health and medical records of patients with a block chain node to construct a personal health record book (My Data) integrating the generated health and medical records.

Specifically, as shown in FIG. 1B, the patient's health record may include the patient's exercise record, meal record, sleep record, genetic record, etc. In addition, heart rate, oxygen saturation, and electrocardiogram input from the user device , Blood pressure, blood sugar, and the like, and the patient's medical record may include the patient's test record, prescription record, medical record, and the like.

Accordingly, the subject of creating the patient's health record and medical record may be a hospital, a public health center, and the patient himself (e.g., a user device), and these generating subjects may be connected to a blockchain node.

In addition, each node shares only the hash value for personal health records in normal times, and can be connected based on a blockchain in situations where necessary. Through this, there is an effect that, as shown in FIG. 3, while personal health records, which were normally distributed by medical institutions, are connected to the individual in case of an emergency, concerns about the commercial use of personal medical information can be ended.

The personal health record ledger integrating the above-described patient's health record and medical record may be shared with at least one of a patient, a guardian, a hospital, and an emergency agency through a cPHR system.

In particular, since the patient's health and medical records provided to the personal health record book are sensitive personal information, it can be provided with the consent of the patient, and in the case of providing the record to the hospital normally, it is provided with the consent of the patient when necessary. It is desirable, but if it is unavoidably difficult to obtain patient consent in an emergency situation, records may be provided with the patient's prior consent, and it is desirable that the records can be viewed only with the authorization of the emergency medical provider.

In addition, the cPHR system according to an embodiment of the present invention may provide at least one of a disease prevention notification, a diet recommendation, a hospital recommendation, and a lifestyle recommendation based on the personal health record book.

Looking at this in more detail, after the cPHR system receives consent to collect information from an institution that holds personal health records, it may provide at least one of disease prevention notification, diet recommendation, hospital recommendation, and lifestyle recommendation using the collected information.

Specifically, the cPHR system may collect individual disease history and seasonal disease patterns from institutions holding personal health records, and may send guidance to prevent diseases experienced by patients at specific periods each year. In addition, the cPHR system can derive individual patients' possible genetic diseases (for example, diabetes) from institutions holding personal health records, analyze the patient's life health information, and continuously send notifications about the patient's possibility of developing genetic diseases. , You can guide lifestyle habits (meal recommendations, hospital recommendations, lifestyle recommendations, etc.) that can prevent the onset of genetic diseases.

According to an embodiment of the present invention, the cPHR system records the personal health record of the emergency patient through the emergency medical provider authentication of the emergency medical provider who has received a report from a third party and dispatched in an emergency situation where the patient is unconscious and there is no guardian nearby. You can provide a ledger.

Specifically, as shown in FIG. 6, when the emergency medical provider terminal is activated based on motion in the terminal of the emergency medical provider, the emergency medical provider can authenticate the emergency medical provider using a fingerprint or pin number. .

Thereafter, only when the patient's prior consent is given, the emergency patient's personal health record book may be provided to the emergency medical service provider using NFC, and FIG. 9 is an example of a screen for providing such a personal health record book.

In addition, when the emergency medical provider is authenticated, an emergency notification may be delivered to a guardian, and an example of the emergency notification may be illustrated in FIG. 10.

In other emergencies, the patient is conscious and may call paramedics.

The cPHR system may provide the personal health record book to emergency personnel, hospitals scheduled to be transferred, and guardians when there is a call from a patient in the emergency situation.

If you look closely at the information provided to the personal health record book, you can see user information, medical treatment information of treatment institutions, examination information of examination institutions, surgery information of surgery institutions, prescription information of prescribing institutions, and life information automatically linked from user devices. I can.

In addition, the user information is input by the user once for the first time, and additional information is updated from time to time, and the treatment information, the examination information, the surgery information and the prescription information are respectively a treatment institution, an examination institution, a surgery institution, and a prescribing institution. It is updated when at least one of treatment, examination, surgery, and prescription is performed in connection with, and the living information is updated at any time by automatically linking sensing information of a smart phone and a wearable device.

Specifically, user information includes personal information such as name, nationality, date of birth, gender, phone number, and address; Body information such as height, weight, and blood type; Guardian information, such as the guardian's name, relationship with the user, and the guardian's phone number; It can be a family history, allergies, smoking status, drinking frequency, and medications you are taking.

The medical treatment information includes institutional information such as name of the hospital, the symbol of the nursing institution, the name of the medical treatment, and the license number of the medical treatment; It can be result information such as treatment date, treatment subject, disease name, disease classification code, health care terminology standard, and initial visit.

The examination information includes institutional information such as the name of the hospital, the symbol of the nursing institution, the name of the medical examiner, and the license number of the medical examiner; It can be result information such as inspection date, inspection name, inspection item name, inspection item code, inspection type, and inspection result.

Surgery information includes institutional information such as name of name, surgical institution symbol, name of operating surgeon, license number of operating surgeon, name of anesthesia, license number of anesthesia, name of assistant, license number of assistant, etc.; Operation date It can be result information such as operation name, operation code, operation method, surgical wound, anesthesia method, preoperative diagnosis name, postoperative diagnosis name, etc.

Prescription information includes institutional information such as hospital name, prescription institution symbol, prescription medical person name, and prescription medical person license number; It can be result information such as prescription date, drug name, number of doses per day, dose per dose, number of doses, KD code, total dose, and usage.

Life information includes activity information such as number of steps, travel time, travel distance, and sleep time; It can be biometric information such as heart rate, oxygen saturation, electrocardiogram, blood sugar, and blood pressure.

In addition, even though the patient's condition deteriorates without notice and the patient suddenly loses consciousness, there may be cases where there are no guardians around. In these cases, it may be difficult for the patient to receive timely action.

For example, it is possible to consider the case of a patient who needs management due to high blood pressure and wears a user device capable of measuring blood pressure at any time.

If it is determined that the patient's condition is deteriorating and the patient is unconscious, the user device can be operated to immediately provide the personal health record book to paramedics, hospitals to be transferred, and guardians, and to notify that there is an emergency. .

Criteria for determining that the patient is unconscious include the case that the patient's heart rate, blood pressure, blood sugar, oxygen saturation level, etc. fluctuate rapidly or there is no movement for a certain period of time beyond a predetermined threshold, and the threshold value is It can be determined in consideration of the patient's physical condition and age.

In addition, the user device may generate an alarm to check whether the patient is conscious. When the patient's condition exceeds a predetermined threshold value set in advance, for example, when the patient's blood pressure rises rapidly, when the user device recognizes that it is a dangerous situation, sound and vibration can be generated so that the patient can hear it. , The patient hears these sounds and vibrations (alarms), and if conscious, the alarm generated by the user device can be stopped. If the patient is not conscious, the alarm generated by the user device cannot be stopped.

Therefore, if the alarm of the user device does not stop for a certain period of time, the user device determines that the patient is unconscious, immediately provides the personal health record book to the paramedics, the hospital to be transferred, and the guardian, and operates to notify the emergency situation. Can be.

In addition, the cPHR system of the present invention may provide hospital information, which is information on the location of a hospital using the cPHR system and information on medical personnel on duty, thereby providing a treatment reservation and storage function.

Specifically, while providing medical records to the personal health record ledger in the hospital, which is the subject of creating medical records, additionally, the location of the hospital, information on the working medical personnel, and the working schedule of the medical personnel can be provided to the cPHR system.

Through this, the patient can access the cPHR system to find a hospital near him and make a medical appointment. In addition, the patient may check whether his or her doctor is working and make an appointment on the day the doctor is treating.

In addition, the cPHR system can provide a storage function using a conventional wireless payment system, through which a patient can receive a payment without using a hospital counter through the cPHR system after completing treatment.

In addition, a method of operating a cPHR service based on a block chain according to an embodiment of the present invention

For example, the collected and managed personal health record (eg, PHR) 191 may include medical treatment information, drug prescription information, sleep pattern, genetic information, diet information, exercise information, and medical test information in a hospital. . This is only exemplary, and is not limited thereto, and may further include personal medical-related information by a skilled person.

According to an embodiment of the present invention, the personal health record 191 may be provided (or transmitted) to the plurality of nodes 193 through the block chain 192. For example, the provided content (or data) may be a hash value, and in some cases, it is also possible to provide the collected information itself. In addition, the system according to an embodiment of the present invention checks the integrity of information by sharing only the hash value with the plurality of nodes 193 when the first condition is satisfied, and when the second condition is satisfied, the medical record data It may share itself with a plurality of nodes 193. For example, in the case of medical information such as medical records and prescriptions among personal health records, security is important, so in normal times, only the hash value is shared to check the integrity of the information. It is possible.

According to an embodiment of the present invention, it is possible to provide only a hash value for some data and the data itself for some data according to the type of data. That is, among data of the same type (eg, including first data and second data), it is possible to provide only the hash value for the first data and the data itself for the second data. In other words, it is also possible to provide only a hash value for at least one of treatment information, drug prescription information, and medical examination information, and provide data itself for at least one of sleep pattern information, meal information, and exercise information. Here, treatment information, drug prescription information, and medical examination information may be included in the first information group, and sleep pattern information, meal information, and exercise information may be included in the second information group.

According to an embodiment of the present invention, a plurality of nodes 193 (for example, an emergency agency, a power agency, a base hospital, a cooperative hospital, a local health center, etc.) are divided into a first node group and a second node group to be set. I can. For example, the first node group can only share information whose sensitivity is greater than or equal to the threshold value, and the second node group can only share information that is less than the threshold value of the information.

For example, the processor 110 may set sensitivity for each of the information included in the first information group and the second information group, and among the pieces of information, information having a sensitivity equal to or greater than a threshold is set as the first sensitivity information. , Among the pieces of information, information whose sensitivity is less than a threshold may be set as second sensitivity information. Here, the sensitivity corresponding to each information may be set by a user who inputs the information, or may be set by an administrator of a server operating a block chain-based cPHR service according to an embodiment of the present invention.

Also, the processor 110 may share the first sensitivity information with at least one node included in the first node group, and share the second sensitivity information with at least one node included in the second node group.

In addition, when the number of stored second sensitivity information among at least one node included in the second node groups exceeds a predetermined threshold, the processor 110 determines that the number of second sensitivity information exceeds a predetermined threshold. May reset the node to a node of the first node group. This may be an operation performed even if the information has relatively low sensitivity, since it is necessary to provide security protection if a large number of information about the patient is included.

In addition, the processor 110 includes information (e.g., medical treatment information, drug prescription information, sleep pattern, etc.) , Genetic information, meal information, exercise information, medical test information, etc.) Alternatively, different algorithms may be performed depending on whether information is stored in a node included in the second node group.

For example, a signal (or message) requesting access to information (e.g., medical information, drug prescription information, sleep pattern, genetic information, meal information, exercise information, medical examination information, etc.) included in a plurality of nodes 193 ) Is received from a hospital terminal and/or a user terminal, the processor 110 includes the type, type, mode, and number of information indicated by the signal, the type, type, and location of the node in which the information indicated by the signal is stored, The number can be checked, and then different algorithms can be performed according to the identified type, type, aspect, and number.

In addition, when the information indicated by the signal is stored in both the node included in the first node group and the node included in the second node group, the processor may perform any one of the first node group and the second node group according to a predetermined criterion. By selecting only a node group, the requested information may be obtained from a node included in the selected node group.

In addition, the processor 110 is a request signal for requesting to view the information (e.g., medical treatment information, drug prescription information, sleep pattern, genetic information, meal information, exercise information, medical test information, etc.) through the network interface 130 ( Or a first time (or a first transmission time) when a request message) is sent, and a second time (or a first reception time) when each of the plurality of nodes 193 receives the request signal (or request message). Information can be obtained. In addition, the processor 110, a third time (or a second transmission time) when a response signal (or response message) transmitted in response to the request signal (or request message) is transmitted from each of the plurality of nodes 193, Information on a fourth time (or a second reception time) when the response signal (or response message) is received by the network interface 130 may be obtained.

The processor 110 includes, for example, information indicated by the signal (eg, medical treatment information, drug prescription information, sleep pattern, genetic information, meal information, exercise information, medical test information, etc.) in the first node group. When stored in both the node and the node included in the second node group, the first time (or first transmission time), the second time (or first reception time), the third time (or second transmission time), Based on at least one of the fourth time (or the second reception time), by selecting/determining whether to acquire information (indicated by the signal) from which node among the plurality of nodes 193, i) the A request signal may be additionally transmitted to the selected node, or ii) information (indicated by the signal) may be received from the selected node. Here, the first time, the second time, the third time, and the fourth time may be obtained based on data obtained by a previously transmitted request signal and a response signal. In addition, the processor 110, for example, among the plurality of nodes 193, at least one of the difference between the first reception time and the first transmission time and the difference between the second reception time and the second transmission time is the shortest. The request signal may be transmitted by selecting only a node or a node lower than a predetermined threshold.

The processor 110 includes, for example, information indicated by the signal (eg, medical treatment information, drug prescription information, sleep pattern, genetic information, meal information, exercise information, medical examination information, etc.) in the first node group. When stored in both the node and the node included in the second node group, the first time (or first transmission time), the second time (or first reception time), the third time (or second transmission time), Information (indicated by the signal) from any node among the plurality of nodes 193, based on at least one of the fourth time (or the second reception time) and the consideration cost required by each of the plurality of nodes 193 You can select/determine whether or not to acquire. For example, the processor 110 may determine the difference between the first reception time and the first transmission time, and the second reception time and the second transmission time among the remaining plurality of nodes after excluding a node whose consideration cost is higher than a predetermined threshold. The request signal may be transmitted by selecting only a node having at least one of the differences between the shortest nodes or a node lower than a predetermined threshold.

Although described with reference to the above embodiments, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention described in the following claims. I will be able to.
