Detailed Description
The embodiments of the present invention will be described below with reference to the drawings.
With the rapid development of information technology, the operation of various large-field platforms increasingly depends on reliable transmission of information, for example, in the medical health field, the safe storage and transmission of user health information are very important for users and medical health institutions. In the traditional medical health field, the individual health information registered by each medical health institution is provided by the user, that is, when the user visits different medical health institutions, the user needs to repeatedly provide the individual health information, and the health information of each visit may be different. That is to say, when a user visits a first medical health institution, the first health information is newly added, when the user visits a second medical health institution, the second health information is newly added based on the first health information, when the user visits a third medical health institution, the first health information and the second health information need to be provided again, and when the first health information or the second health information is omitted, the health information is leaked, the difficulty of visiting the user is increased, and the like.
Taking a user with an ophthalmic disease as an example, when the user visits an ophthalmic special hospital, the ophthalmic special hospital registers personal information and ophthalmic disease information of the user in a system of the hospital, if the user has neuropathic pain caused by the ophthalmic disease, when the user visits another hospital different from the ophthalmic special hospital, the user needs to re-provide the personal information and ophthalmic disease information and new neuropathic pain information, once the user loses a diagnosis result list of the ophthalmic special hospital, the hospital which registers information for the second time cannot comprehensively know the personal health information of the user, and the like, so that the workload of the hospital is increased, and the work efficiency of the hospital is reduced.
In order to solve the above problems, embodiments of the present invention provide a method and related device for storing health information, where the method and related device are implemented based on a block chain technique.
The realization of interconnection and intercommunication of various medical health institutions means that personal health information of users can exist in a block chain network to which a plurality of health information institutions belong. For example, after the user registers the personal health information of the user in a private clinic, when the personal health information is for other healthcare institutions in the area to which the private clinic belongs, and the number of successfully verified pieces of the verification results of other node devices in the blockchain network is greater than a second preset threshold, the personal health information of the user can be persistently stored in the blockchain network to which the plurality of healthcare institutions belong, so that the personal health information can be conveniently read by each healthcare institution in the blockchain network. The embodiment of the present invention is described by taking the case where the medical health institution shares the personal health information as an example, and is not limited to the embodiment of the present invention.
The Block Chain (BC) is a novel application mode of computer technologies such as distributed data storage, consensus mechanism, encryption algorithm and the like, and has the characteristics of decentralization, openness, independence, safety, anonymity and the like. Generally, a traditional transaction model is a transaction model constructed based on centralized thinking, that is, on the premise that two transaction parties do not trust each other, the centralized formation of a third party is promoted, and the third party serves as an arbitrator to witness the activities of the two transaction parties in the transaction process. The decentralized feature of the blockchain technology means that in a blockchain network, each node device stores data, data redundancy is realized through distributed storage, all nodes can have the ability to maintain the safety of a database, and the whole transaction is autonomous and simplified.
The embodiment of the invention provides a health information storage method, which specifically comprises the following steps: the first node equipment in the block chain network acquires the personal health information of the user, and verifies the personal health information to obtain a verification result. And when the verification result is that the verification is successful, the first node equipment generates a block according to the personal health information, and the block is issued to the block chain network to which the first node equipment belongs.
By implementing the embodiment of the invention, the first node equipment issues the block to the blockchain network, so that each second node equipment in the blockchain network can store the block, the fair sharing of the personal health information successfully verified by each node equipment in the blockchain network is realized, and the personal health information successfully verified is acquired by each second node equipment in the blockchain network through the first node equipment, so that the personal health information acquired by each second node equipment has reliability.
Taking the schematic architecture of the health information storage system shown in fig. 1 as an example, the health information storage system includes at least one first node device 101 and at least one second node device 102. The first node device and each second node device form a block chain network, and all the node devices in the block chain network share the personal health information in the block chain network. The first node device 101 and the second node device 102 may be respective medical health institutions, wherein each medical health institution may include: a large hospital, a small hospital, or a nursing home. The large hospital may be a special hospital or a comprehensive hospital, and the small hospital may be a private clinic or a physical examination center, which are not limited in the embodiments of the present invention.
For the architecture diagram of the health information storage system shown in fig. 1, it should be noted that the second node device is another node device in the blockchain network, except for the first node device, the number of the second node devices may be one or more, and names of the second node devices are not limited in the embodiments of the present invention, for example, the blockchain network includes a first node device, a second node device, a third node device, a fourth node device, and the like, where the first node device, the second node device, the third node device, and the fourth node device are different from each other, the first node device is a node device obtained by election of each node device in the blockchain network through a consensus algorithm, and the second node device, the third node device and the fourth node device are other node devices except the first node device in the blockchain network.
It should be noted that the first node device is obtained by periodically electing each node device in the block chain network through a consensus algorithm, and the first node devices obtained by electing at different periods may be the same or different. For example, in a certain period, the blockchain network elects a comprehensive hospital a as the first node device of the blockchain network, and then other medical health institutions in the blockchain network are the second node devices, and correspondingly, in a certain period, the blockchain network may elect a private person as the first node device of the blockchain network instead of electing the comprehensive hospital a as the first node device of the blockchain network.
As shown in fig. 1, the first node device 101 obtains the personal health information of the user, and verifies the personal health information to obtain a verification result. When the verification result is that the verification is successful, the first node device 101 generates a block according to the personal health information, and sends the block to each second node device 102, and each second node device 102 stores the block.
The personal health information includes identity information and health information, and the identity information includes but is not limited to: one or more items of user photos, user names, user ages, user sexes, user addresses, user telephones and user mailbox addresses, and health information includes but is not limited to disease names, disease treatment effects and the like. The manner in which the first node device obtains the personal health information includes, but is not limited to: the registration information is obtained through paper registration information, electronic registration information and the like, wherein the paper registration information may include: a user medical record sheet, a user physical examination report, and the like.
Therefore, the first node device in the block chain network generates the block for the personal health information which is successfully verified according to the verification result, and sends the block to each second node device, and each second node device stores the block, so that the node devices in the block chain network can fairly enjoy the personal health information of the user.
Based on the architecture diagram of a health information storage system shown in fig. 1, fig. 2 provides a flow chart of a health information storage method, which includes, but is not limited to, the following steps:
step S201: the first node device obtains personal health information of a user.
Specifically, the first node device receives a registration personal health information request of the user, and acquires the personal health information of the user based on the registration personal health information request of the user.
In one implementation manner, the first node device stores at least one block related to the personal health information, and after the first node device acquires the personal health information of the user, the first node device determines whether the acquired personal health information is the same as the stored personal health information of the at least one block. When the acquired personal health information is different from the stored personal health information of at least one block, the first node equipment determines that the acquired personal health information is not linked, and then the first node equipment checks the acquired personal health information. When the acquired personal health information is the same as the stored personal health information of at least one block, the first node device determines that the acquired personal health information is linked, and then deletes the acquired personal health information, so that the same personal health information is prevented from being stored repeatedly.
For example, the first node device is an orthopedic hospital a, and after the orthopedic hospital a acquires the personal health information of the user, the orthopedic hospital a determines whether the acquired personal health information is the same as the stored personal health information of the at least one block. If the acquired personal health information is different from the stored personal health information of the at least one block, the orthopedic hospital A checks the acquired personal health information, and if the acquired personal health information is the same as the stored personal health information of the at least one block, the orthopedic hospital A deletes the acquired personal health information.
Step S202: the first node device verifies the personal health information.
Specifically, the first node device verifies the acquired personal health information, generates a block based on the personal health and issues the block to the blockchain network if the verification is successful, and correspondingly, each second node device in the blockchain network receives and stores the block.
In one implementation, the first node device performs keyword verification on the personal health information, so as to determine whether the personal health information belongs to the content of the health field. Specifically, the first node device performs keyword recognition on the personal health information to obtain a first keyword of the personal health information, the first node device obtains similarity between the first keyword and each second keyword in a preset database, and when the second keyword exists in the preset database, the similarity between the first keyword and each second keyword in the preset database is greater than a first preset threshold, it is determined that the personal health information is successfully verified. And the first node equipment has a preset database.
For example, the first node device performs keyword recognition on the personal health information to obtain keywords existing in the personal health information, performs similarity comparison on the obtained keywords and a preset database, and determines that the personal health information belongs to the content of the health field when the similarity between at least one keyword existing in the personal health information and the keywords in the preset database is greater than a first preset threshold.
For example, assuming that the first preset threshold is 50%, the first node device includes a specialized hospital, and the specialized hospital performs keyword recognition on the personal health information of the user, and the obtaining of the personal health information of the user through the keyword recognition includes: the first node device judges that the personal health information of the user belongs to the content of the health field if the similarity between at least 1 keyword in the 4 keywords and the keywords in the preset database is more than 50%. The foregoing example is only used to illustrate one implementation method of the block chain network with respect to the keyword checking method, and the embodiment of the present invention does not limit this to other feasible implementation manners.
Therefore, after the first node device acquires the personal health information, keyword verification is carried out on the personal health information, and the personal health information generation block is issued to the block chain network only after the keyword verification is successful. The first node device can be prevented from publishing personal health information which does not belong to the field to the blockchain network, so that the memory space of the blockchain network is wasted.
In one implementation, a first node device searches for a user identifier in personal health information, acquires identification information corresponding to the user identifier, determines that verification of the personal health information is successful when the identity information in the personal health information is the same as the identification information, and determines that verification of the personal health information is failed when the identity information in the personal health information is different from the identification information.
Specifically, the verification method for determining whether the source of the personal health information is legal by using the user identity information may be: the first node equipment acquires the identity information and the user identification of the user from the personal health information of the user, acquires the identity certification information of the user according to the user identification, judges whether the identity information in the personal health information is the same as the identity certification information or not, if the identity information in the personal health information is the same as the identity certification information, the verification is successful, and if the identity information in the personal health information is not the same as the identity certification information, the verification is failed.
The identity information in the personal health information may include: the user photo, the user name, the user age, the user gender, the user address, the user telephone and the user mailbox address, and the user identifier in the personal health information may include: user photo, user name, user age, user gender, user address, user phone, and user mailbox address. The method for the first node device to obtain the identity information according to the user identifier may be as follows: downloading identification information via the internet, etc. The identification information may include: user photo, user name, user age, user gender, user address, user personal information two-dimensional code, user telephone or user mailbox address, etc.
For example, if the identity information in the personal health information is a user photo, the user identifier in the personal health information is a user name, and the first node device finds the identification information of the user according to the user identifier, the first node device compares whether the user photo in the identity information of the personal health information is the same as the user photo in the identification information found according to the user identifier. If the user photo in the identity information of the personal health information is the same as the user photo in the identity information found according to the user identification, the first node device determines that the source of the personal health information is legal, then the first node device can verify the personal health information, if the user photo in the identity information of the personal health information is different from the user photo in the identity information found according to the user identification, the first node device determines that the source of the personal health information is illegal, and then the first node device deletes the personal health information.
Therefore, whether the identity information in the personal health information of the user is the same as the identity information obtained based on the user identifier or not is judged through the first node device, whether the source of the personal health information is legal or not can be judged, and the reliability of the personal health information obtained by the first node device can be improved.
In one implementation manner, the way for the first node device to check the personal health information may be: the first node equipment carries out keyword recognition on the personal health information to obtain a first keyword of the personal health information, obtains the similarity between the first keyword and each second keyword in a preset database, searches a user identification in the personal health information, and obtains identification information corresponding to the user identification. And when a second keyword with the similarity between the second keyword and the first keyword being greater than a first preset threshold exists in the preset database and the identity information in the personal health information is the same as the identity card information, determining that the personal health information is successfully verified. And when a second keyword with the similarity between the second keyword and the first keyword being greater than a first preset threshold value does not exist in the preset database, or the identity information in the personal health information is different from the identity information, determining that the verification of the personal health information fails. The verification method for determining whether the personal health information belongs to the content of the health field by using the keyword of the personal health information and the verification method for determining whether the source of the personal health information is legal by using the user identity information are given in the two implementation methods, and are not described herein again.
The embodiment of the application does not limit the sequence of execution of the first node device for performing keyword recognition on the personal health information to obtain the first keyword of the personal health information and the step of searching the user identifier in the personal health information to obtain the identification information corresponding to the user identifier. For example, when the first node device verifies the personal health information, the keyword verification method may be executed first, and then the user identifier verification method may be executed; for another example, when the first node device verifies the personal health information, the user identifier verification method may be executed first, and then the keyword verification method may be executed; for another example, when the first node device verifies the personal health information, the user identifier verification method and the keyword verification method may be executed at the same time.
As can be seen, the first node device performs keyword verification on the personal health information to obtain a verification result, generates blocks for the verification result as the successfully verified personal health information, and sends the blocks to the second node devices, so that it can be determined that the personal health information issued to the block chain network by the first node device belongs to the health field. In addition, the first node device can make the source of the personal health information issued to the blockchain network by the first node device reliable by comparing whether the identity information of the personal health information is the same as the identity identification information of the user.
Step S203: and if the first node equipment successfully verifies the personal health information, the first node equipment generates a block according to the personal health information.
Specifically, the first node device processes the personal health information to obtain a digital signature of the personal health information, and the first node device generates a block according to the personal health information and the digital signature of the personal health information.
In one implementation, the first node device obtains multiple copies of the individual health information at the same time period, and the first node device may pack the multiple copies of the individual health information at the same time period into one block. Specifically, assuming that the first node device successfully verifies the different pieces of personal health information of the multiple users within the same time period, the first node device may package the different pieces of personal health information successfully verified among the multiple users into one block, and issue the block to the block chain network. For example, in a private clinic, 2 users register personal health information in the same time period, and when the verification results of the private clinic on the personal health information of the two users are both successful, the comprehensive hospital can pack the different personal health information of the 2 users into one block.
In one implementation, the first node device may obtain the number of the personal health information successfully verified, and when the number of the personal health information successfully verified reaches a preset number, the first node device may pack the personal health information successfully verified into one block. For example, assuming that the preset number is 5 pieces of personal health information, when the first node device obtains 7 pieces of personal health information and the number of the pieces of personal health information with the verification result of successful verification is 6 pieces, the first node device determines that the number of the 6 pieces of personal health information with successful verification is greater than the number of the 5 pieces of personal health information, that is, the number of the 6 pieces of personal health information with successful verification reaches the preset number, and then the first node device packages the 6 pieces of personal health information with the verification result of successful verification into one block. The embodiment of the invention does not limit the preset number.
Therefore, the first node device packs a plurality of pieces of personal health information into one block, so that the transmission efficiency of the first node device can be improved, and the use of a memory space is reduced.
Step S204: the first node device issues the block to the blockchain network to which the first node device belongs.
Specifically, the first node device may send the block to each second node device in the blockchain network to which the first node device belongs, and the first node device issues a notification of the persistent block to the blockchain network, and each second node device may locally store the block. By the way of distributing the block to the block chain network, the distributed personal health information is transparent and shared to all node devices in the block chain network.
As can be seen, by implementing the embodiment of the present invention, the first node device verifies the acquired personal health information, and when the verification result is that the verification is successful, the first node device generates a block according to the personal health information, and the first node device sends the block to each second node device in the block chain network. The method and the device can realize that the node devices in the blockchain network share the personal health information fairly, and ensure that the personal health information sent by the first node device to each second node device of the blockchain network has reliability.
Fig. 3 is a schematic flow chart of another health information storage method provided in an embodiment of the present invention, which includes but is not limited to S301 to S309, where:
step S301: personal health information is obtained.
Specifically, the execution process of step S301 may refer to step S201 in fig. 2, which is not described herein again.
Step S302: the first node device verifies the personal health information.
Specifically, the execution process of step S302 may refer to step S202 in fig. 2, which is not described herein again.
Step S303: and if the verification result of the first node equipment on the personal health information is successful, the first node equipment generates a digital signature of the first node equipment.
Specifically, the first node device may generate the digital signature of the first node device when the verification result of the first node device on the personal health information of the user is successful. The digital signature is obtained by the first node device signing the personal health information according to the private key of the first node device.
Step S304: and sending the personal health information and the digital signature of the first node device to each second node device.
Specifically, in addition to sending the personal health information to each second node device of the blockchain network, the first node device also sends the digital signature of the first node device to each second node device of the blockchain network.
Therefore, the first node device sends the personal health information and the digital signature of the first node device to each second node device in the block link network, so that the personal health information is not falsified in the transmission process, and the safety of the personal health information is ensured.
Step S305: each second node device receives the personal health information and the digital signature of the first node device and verifies the personal health information and the digital signature of the first node device.
Specifically, the first node device issues the personal health information and the digital signature of the first node device to the block chain network on the premise that the personal health information is successfully verified, and accordingly, each second node device receives the personal health information and the digital signature of the first node device and verifies the digital signature of the first node device to obtain a verification result.
In one implementation, each second node device may only verify the personal health information. And if the second node device successfully verifies the personal health information, the fact that the personal health information issued to the blockchain network by the first node device is credible is shown. Wherein, the verifying the personal health information by each second node device comprises: and checking the keyword and the user identifier. The verification method of the keyword verification and the user identifier verification is elaborated in step S202, and is not described herein again.
In one implementation, each second node device may only verify the digital signature of the first node device. Specifically, each second node device verifies the digital signature of the first node device through the public key, and when the verification result is that the verification is successful, it indicates that the first node device digitally signs the personal health information through the correct private key, that is, the first node device is a node device in the block chain network, and the identity of the first node device is legal.
Therefore, the second node device checks the digital signature of the first node device, and whether the identity of the sender (the first node device) of the personal health information is legal or not can be determined, so that the reliability of the personal health information in the block chain network is improved.
In an implementation manner, each second node device may verify the personal health information and the digital signature of the first node device, and the specific verification manner is given in the two implementation manners and is not described herein again.
It should be noted that the verification process of the digital signature of the first node device or the personal health information by each second node device in the blockchain network is not affected by other node devices in the blockchain network. For example, when the check result of a certain node device in the blockchain network is a check failure, the check result of the node device does not affect the check process of other node devices in the blockchain network, and even does not affect the check results of other node devices.
The embodiment of the invention does not limit the verification sequence of the personal health information and the digital signature of the first node equipment by each second node equipment. For example, the second node device may perform verification of the personal health information first, and then perform verification of the digital signature of the first node device; for another example, the second node device may verify the digital signature of the first node device first, and then verify the personal health information; for another example, the second node device may perform the verification of the digital signature and the personal health information of the first node device simultaneously.
Step S306: and each second node device in the block chain network sends the check result to the first node device.
Step S307: and the first node equipment generates the personal health information into blocks according to the verification results sent by the second node equipment.
Specifically, the first node device receives the verification result of each second node device, and the verification result of each second node device may be a successful verification or a failed verification. And when the number of successful verification in the verification results of the plurality of second node devices is larger than a second preset threshold value, the first node device generates a block according to the personal health information.
For example, assuming that the second preset threshold is 50%, in a specific example, it is assumed that the check result received by the first node device includes: if 2 verification succeeds and 1 verification fails, the first node device may determine that, in the verification results of the plurality of second node devices, the number of node devices successfully verified is 66% of the total verification results, and 66% is greater than 50%, and then the first node device generates a block according to the personal health information.
Therefore, the first node device determines whether the personal health information is generated into the block or not by judging the verification results of the plurality of second node devices, so that the block issued to the block chain network can be ensured to be successfully verified by most of the node devices in the block chain network, and the reliability of the personal health information is improved.
Step S308: the first node device issues the generated tiles to a blockchain network.
Specifically, the first node device issues the block to the blockchain network, that is, the first node device sends the block to other node devices in the blockchain network.
In one implementation, a first node device issues a blockchain network with a blockchain notification. The persistent block refers to a block permanently stored by a node device in a blockchain network.
In an implementation method, the first node device may issue a persistent block notification to the blockchain network after the local persistent block, and each second node device in the blockchain network performs persistent storage on the block, or the first node device may issue the persistent block notification to the blockchain network and then performs local persistent block, which is not limited in the embodiment of the present invention.
Therefore, by implementing the embodiment of the present invention, each second node device in the blockchain network can verify the personal health information acquired by the first node device, that is, the management of the personal health information in the blockchain network is participated by all the node devices in the blockchain network, thereby ensuring that the personal health information issued to the blockchain network is successfully verified by most of the node devices in the blockchain network.
Fig. 4 is a schematic flow chart of another health information storage method provided in an embodiment of the present invention, which includes, but is not limited to, steps S401 to S408, where:
step S401: the first node device obtains personal health information of a user.
Step S402: the first node device verifies the personal health information.
Step S403: and the first node equipment generates a block according to the personal health information on the premise of successfully verifying the personal health information.
Step S404: the first node device issues the block to the blockchain network to which the first node device belongs.
Steps S401 to S404 are the same as steps S201 to S204 of fig. 2, and are not described herein again.
Step S405: each second node device receives the block and transmits its own attribute information to the first node device.
Specifically, after the first node device issues the block to the block chain network, each second node device sends its own attribute information to the first node device.
The embodiment of the invention takes the medical health field as an application scene, and for each medical health institution, the medical health institution has attribute information about the medical health institution. The attribute information includes, but is not limited to, a grade classification of the health care institution, a classification of a good department of the health care institution, whether the health care institution can reimburse a medical insurance, and the like.
For example, assuming that there are private clinics, specialized hospitals, and physical examination centers in a blockchain network in the medical health field, which are three medical health institutions, the attribute information may be departments that the three medical health institutions are respectively good at. For example, specialized hospitals are good at orthopedics, private clinics are good at acupuncture, and physical examination centers are good at dermatology. After each healthcare institution receives the block, the department that the individual is skilled in sends the block to the healthcare institution (first node device) where the user is located. In the above example, the attribute information is department information of each health care institution. The attribute information of each health care institution is described by taking a specific health care institution as an example, but the attribute information is not limited to the above, and the attribute information of the health care institution is not limited in the embodiment of the present invention.
Step S406: the first node device acquires the matching degree between the personal health information and the attribute information of each second node device.
Specifically, the first node device performs keyword recognition on the personal health information to obtain keywords of the personal health information, and the first node device compares the keywords of the personal health information with the attribute information of each second node device to obtain the matching degree of the keywords of the personal health information and the attribute information of each second node device.
In one implementation, the first node device may compare the keyword of the personal health information with the attribute information of each second node device, so that the first node device obtains a matching degree between the personal health information and the attribute information of each second node device. Specifically, the first node device performs keyword identification on the acquired personal health information to obtain keywords in the personal health information, and compares the keywords identified from the personal health information with attribute information fed back by each second node device to obtain a matching degree between the keywords of the personal health information and the attribute information of each second node device. That is, the first node device obtains the matching degree between the personal health information provided by the user and each of the second node devices by comparing the matching degree between the keyword of the personal health information and the attribute information of each of the second node devices. The matching degree refers to the correlation between the personal health information and the attribute information of the second node device.
For example, the first node device includes a physical examination center a, the two second node devices include a physical examination center B and a physical examination center C, and the keywords of the personal health information acquired by the physical examination center a are as follows: the physical examination center A receives the attribute information of the physical examination center B as the head and the hand numbness, the physical examination center A receives the attribute information of the physical examination center C as the hand soreness and the hand numbness, the physical examination center a may determine that the degree of matching between the keyword of the personal health information and the attribute information of the physical examination center B is 50%, the physical examination center a may determine that the degree of matching between the keyword of the personal health information and the attribute information of the physical examination center C is 100%, the physical examination center a thus obtains the degree of matching between the keywords of the personal health information and the attribute information of the physical examination center B and the physical examination center C, that is, the physical examination center a obtains the degree of matching between the personal health information and the attribute information of the physical examination center B and the physical examination center C, so that the physical examination center a can output the push message based on the degree of matching.
In one implementation manner, each second node device may match the personal health information with its own attribute information, and send the matching result to the first node device, so that the first node device obtains the matching degree between the personal health information and each second node device. Specifically, after each second node device receives the personal health information of the user, each second node device in the blockchain network may identify a keyword of the personal health information, match the keyword of the personal health information with attribute information of the second node device, send a matching degree obtained through the matching to the first node device, and the first node device may push a second node device identifier (target device identifier) related to the personal health information of the user to the user according to the received matching degree.
For example, the first node device is a medical health institution a, the medical health institution a generates a block of the personal health information of the user and sends the block to a medical health institution B, the medical health institution B performs keyword recognition on the personal health information according to the personal health information in the block, matches the keyword of the personal health information with the attribute information of the medical health institution B to obtain a matching degree between the personal health information and the attribute information of the medical health institution B, and the medical health institution B sends a matching degree result to the medical health institution a. Therefore, the personal health information is matched with the attribute information of each second node device through the first node device to obtain the matching degree, or each second node device matches the personal health information with the attribute information of the second node device to obtain the matching degree, and each second node device sends the matching degree to the first node device, so that the first node device can obtain the target device identification related to the personal health information of the user.
It should be noted that the keyword identification of the personal health information by the first node device or the second node device includes: firstly, carrying out keyword identification of disease effect on a medical record of a user; and secondly, carrying out keyword recognition on the physical examination report result of the user. For example, the first node device is a private clinic, and if the keyword obtained by the private clinic on the medical record of the user is "dizziness", the first node device may match the "dizziness" with the attribute information of each second node device to obtain the second node device identifier with the highest degree of association with the disease condition of the user. For example, the user arrives at a physical examination center to perform a physical examination, and the physical examination center determines the department classification of the illness state of the user after performing item physical examination on a physical examination sheet on the user, so that after the physical examination is finished, the physical examination center can obtain the second node device identifier with the highest association degree with the illness state of the user according to matching between the physical examination result after the physical examination and the attribute information of each second node device.
Step S407: and if the first node equipment judges that the matching degree is greater than the preset matching degree, the first node equipment outputs the push message.
In one implementation manner, a first node device identifies a keyword of personal health information, matches the keyword of the personal health information with attribute information of each second node device, obtains a matching degree between the personal health information and the attribute information of each second node device, and determines a target device identifier according to the matching degree, and the first node device may generate a push message according to the target device identifier, where the push message may include the target device identifier, and the target device identifier points to the target device.
The manner in which the first node device generates the push message according to the target device identifier may include: and determining the second node equipment identifier with the highest matching degree as the target equipment identifier, or determining the second node equipment identifier with the matching degree larger than the preset matching degree as the target equipment identifier, or determining the equipment identifier of the second node equipment with the highest matching degree in the plurality of second node equipment with the matching degree larger than the preset matching degree as the target equipment identifier.
For example, assuming that the first node device determines that the preset matching degree of the personal health information and the attribute information of the second node device is 50%, in a specific example, the second node device includes a medical health institution whose attribute information is "acne mark", "whelk", "skin", and when the keyword recognized by the first node device from the personal health information of the user is "skin" and "whelk", the keyword of the personal health information: "skin", and a keyword of the attribute information of the second node device: the "skin" is the same, the keywords of personal health information: "whelk", and a keyword of the attribute information of the second node device: the "whelk" is the same, the first node apparatus may determine that the matching degree between the attribute information of the second node and the keyword of the personal health information is 100%, where 100% is greater than 50%. That is, if the first node device determines that the matching degree between the attribute information of the second node device and the personal health information is greater than the preset matching degree, the first node device outputs the device identifier (target device identifier) of the second node device.
The manner of outputting the push message includes, but is not limited to, voice broadcasting, sending information, or screen display, and the content of the push message may include: and the second node equipment identifier achieves the preset matching degree with the personal health information of the user. The push message is used to advise the user to select a node device that is more appropriate for the personal health information. For example, the medical health institution may suggest a user to select a skin medical health institution more suitable for the condition of the patient in a voice broadcast manner by diagnosing the user and finding that the user has a skin problem, thereby helping the user to achieve a targeted selection of the medical health institution.
In one implementation manner, the first node device receives the matching degree of each second node device, and the first node device obtains a device identifier of a second node device of which the matching degree is greater than a preset matching degree among the plurality of second node devices, and then the first node device outputs a device identifier (target device identifier) of the second node device of which the matching degree is greater than the preset matching degree.
For example, assuming that the preset matching degree is 50%, in a specific example, if the first node device receives that the matching degrees of 3 second node devices are 30%, 60%, and 90%, and then the first node device determines that 60% and 90% are greater than 50%, the first node device determines that the second node devices corresponding to the matching degrees of 60% and 90% are target devices related to the personal health information of the user, and then the first node device outputs the device identifiers of the second node devices corresponding to the matching degrees of 60% and 90%.
Therefore, by implementing the embodiment of the invention, the first node device acquires the matching degree of the personal health information and each second node device and outputs the push message according to the matching degree, so that the user can find the node device which is more suitable for the personal health information of the user compared with the first node device according to the target device identifier in the push message.
