Fig. 2 is a schematic flow chart of a medical information processing method according to another embodiment of the present application. The method can be applied to operator nodes in a blockchain network, wherein the blockchain network further comprises user nodes, hospital nodes and medical insurance nodes.

As shown in fig. 2, the medical information processing method includes, but is not limited to, the following steps.

Step S201, the identity information of the user node is verified, and a first verification result is obtained.

The identity information may be information obtained in an authentication message sent by the user node.

For example, an authentication message sent by a user node is obtained from a blockchain network, where the authentication message includes a blockchain identifier of the user node and an identity encryption result, the blockchain identifier of the user node is a value obtained by performing a hash operation on an identifier of a terminal used by the user node, and the identity encryption result is a result obtained by encrypting identity information of the user node by the user node using a public key of an operator node; decrypting the identity encryption result by using a private key of the operator node to obtain identity information of the user node; searching a database according to the identity information of the user node, obtaining an identifier of a preset terminal corresponding to the user node, and performing hash operation on the identifier of the preset terminal to obtain a preset hash value; and determining a first verification result according to the preset hash value and the block chain identification of the user node.

It should be noted that, because the identifier of the terminal used by the user node has uniqueness, the value obtained by performing hash operation on the identifier of the terminal used by the user node is used as the block chain identifier of the user node, so that the user node can be uniquely represented, and the confusion of the information of the user node is avoided. Moreover, the public key of the operator node is adopted to encrypt the identity information of the user node to obtain an identity encryption result, so that the security of the identity information of the user node in the transmission process can be ensured, and the possibility of the identity information of the user being leaked is reduced.

Step S202, under the condition that the first verification result is determined to be verification passing, encrypted random verification data is sent to the user node in a short message mode in a mobile switching network so that the user node can obtain the random verification data.

The encrypted random verification data is sent to the user node in a short message mode, so that the encrypted random verification data can be prevented from being intercepted or tampered by third-party equipment, and the safety of the data is ensured.

Step S203, obtaining the data to be verified fed back by the user node from the block chain network within the preset time length.

The preset time duration may be a preset time duration such as 1 minute or 3 minutes, the preset time duration is only an example, and other unexplained preset time durations are also within the protection scope of the present application and are not described herein again.

It should be noted that the operator node needs to obtain the data to be verified fed back by the user node within the preset time length to ensure that the data to be verified can be compared with the random verification data randomly generated by the operator node, and if the operator node does not receive the data to be verified fed back by the user node within the preset time length, the operator node does not perform re-verification on the user node; therefore, the user node cannot be further verified, and at this time, the user node is judged to be an illegal node, and the user node is not allowed to be accessed into the block chain network.

Through the setting of the preset time length, the judgment of the user node can be accelerated, the working efficiency of the operator node is improved, and the judgment accuracy of the user node is improved.

And step S204, verifying the user node again according to the random verification data and the data to be verified to obtain a second verification result.

Wherein the second verification result comprises: and the user node is authenticated or not authenticated.

If the random verification data is different from the data to be verified, the second verification result is that the user node is not verified; and if the random verification data is the same as the data to be verified, the second verification result is that the user node is verified to be passed.

The random verification data is used for verifying the data to be verified fed back by the user node again, so that the user node can be further verified, and the verification accuracy of the user node is improved.

And step S205, under the condition that the first verification result and the second verification result are both verified, acquiring and forwarding the medical request message sent by the user node to the blockchain network so that the hospital node obtains the medical request message.

It should be noted that step S205 in this embodiment is the same as step S103 in the previous embodiment, and is not repeated herein.

Step S206, generating and sending a medical response message to the blockchain network according to the identity information of the user node, the prescription information and the medical expense information acquired from the blockchain network, so that the user node can acquire the prescription information and the medical expense information.

Wherein, the medical expense information comprises: at least one of the medical insurance type, reimbursement proportion information and preset medical insurance cost information within a preset time length corresponding to the user node.

For example, the medical insurance type can include commercial medical insurance and/or social medical insurance, and the commercial medical insurance can include at least one of commercial inpatient medical insurance, commercial accidental injury medical insurance, commercial surgical medical insurance, and general commercial medical insurance.

Different types of medical insurance have different corresponding reimbursement proportions, and correspondingly different available preset medical insurance cost information within a preset time (for example, one year and the like), and according to the medical expense information of different user nodes, the reimbursement proportions matched with the user nodes are searched through the medical insurance nodes, so that the expenditure of medical expenses can be reduced as much as possible by the user nodes; and a mode based on a block chain network is adopted, so that the user node can remotely obtain prescription information and medical expense information, and the use experience of the user is improved.

The embodiment of the present application provides another possible implementation manner, where before the step S103 or step S205 is executed, and in a case that it is determined that both the first verification result and the second verification result pass verification, the method further includes, before acquiring and forwarding a medical request message sent by a user node to a blockchain network, the method further includes: acquiring a block chain identifier of a user node, searching a block chain account book according to the block chain identifier of the user node, and acquiring a searching result; and under the condition that the search result is determined that the block chain account book does not comprise the block chain identification of the user node, registering the user node into the block chain network.

The block chain account book stores information of user nodes registered in a block chain network, and block chain identification of the user nodes can uniquely represent the user nodes; if the blockchain account book does not include the blockchain identifier of the user node, it indicates that the user node is not registered in the blockchain network, and a response needs to be made to a registration request sent by the user node, so that the user node can be registered in the blockchain network and can use related resources in the blockchain network in a legal manner.

It should be noted that the identifier of one terminal can only be registered once in the blockchain network, so as to ensure the unique information of the user node, avoid information confusion of different user nodes, and improve the service accuracy of the user node.

In some specific implementations, after executing the step S104 or the step S206 to generate and send the medical response message to the blockchain network according to the identity information of the user node, the prescription information and the medical cost information acquired from the blockchain network, so that the user node obtains the prescription information and the medical cost information, the method further includes: acquiring a second hash value, wherein the second hash value is obtained by carrying out hash operation on prescription information by a hospital node; and writing the second hash value, the first hash value and the identity information of the user node into the block chain account book.

Wherein the prescription information includes: drug information and/or real-time exam information.

For example, the real-time inspection information may include: at least one of laboratory test report information, examination report information, test result and examination result. The medicine information may be the name of the medicine, the dosage and the like of the medicine required to be used by the user node, which are determined by the hospital node according to the real-time examination information.

Through writing the second hash value, the first hash value and the identity information of the user node into the blockchain account book, the related information of the user node in the process of interacting with the hospital node can be recorded into the blockchain account book, and the related information can be conveniently searched and used subsequently. For example, in the case of sending a medical dispute, the relevant medical information of the user node may be obtained by searching the block chain ledger, so as to prove the accuracy of the interaction information between the user node and the hospital node. Moreover, the safety of prescription information and medical expense information can be ensured through the first hash value and the second hash value, and the block chain network is adopted to record and transmit the medical information and the identity information of the user node, so that the possibility that the information of the user is tampered can be reduced, and the information safety of the user can be protected.

The first hash value can represent historical inspection data of the user node, and the historical inspection data of the user node is analyzed, for example, detection parameters in the historical inspection data are verified, or medication information in the historical inspection data is adjusted, so that the generated prescription information can further meet the current state of the user node, the user node can obtain medicine information required by the user node, and the use experience of the user is improved.

In some specific implementations, the processing of the user node according to the first hash value in step S303, obtaining and sending prescription information required by the user node to the block chain network, so that the operator node obtains the prescription information, may also be implemented in the following manner:

Fig. 7 shows a flowchart of an operating method of a medical information processing system provided by an embodiment of the present application. As shown in fig. 7, the method of operation of the medical information processing system includes, but is not limited to, the following steps.

Step S701, the user node 602 acquires the public key and the identifier of the operator node 601 from the blockchain network, and encrypts the identity information of the user node 602 by using the public key of the operator node 601 to generate an identity encryption result; then, the user node 602 performs hash operation on the identifier of the terminal used by the user node according to a preset algorithm to generate a first hash value, and uses the first hash value as the blockchain identifier of the user node 602.

The identifier of the terminal may include: mobile phone number, equipment number of terminal, etc. The identity information of the user node 602 includes: at least one of a user's name, identification number, and address information.

It should be noted that, when initially accessing the blockchain network, the user node 602 only needs to acquire the public key and the identifier of the operator node 601, and does not need to synchronize all the account book information in the blockchain network, so as to save the terminal power and the storage space of the user node 602. The identity encryption result can ensure that the privacy information of the user node 602 is not leaked, and the personal information security is improved. In addition, the first hash value is used as the block chain identifier of the user node 602, and due to the uniqueness of the identifier of the terminal, the uniqueness of the first hash value can be ensured, so that the repetition of identifiers of different users can be avoided, and the distinguishing characteristics of the users can be improved.

In step S702, the user node 602 generates an authentication message according to the first hash value and the identity encryption result, signs the authentication message using the private key of the operator node 601, and generates and sends the signed authentication message to the blockchain network, so that the operator node 601 obtains the authentication message.

Step S703, after obtaining the signed authentication message from the blockchain network, the operator node 601 verifies the signed authentication message using its own public key, and obtains an authentication encryption result and a first hash value in the authentication message when it is determined that the verification passes; then, according to a preset algorithm, the private key of the operator node 601 is used to decrypt the identity encryption result, and the identity information of the user node 602 is obtained.

Step S704, the operator node 601 sends the short message to the user node 602 in the mobile switching network in the short message mode.

Wherein, the SMS includes: the encrypted random authentication data is obtained by encrypting the randomly generated random challenge data using the public key of the user node 602 according to a preset algorithm.

It should be noted that, by sending the encrypted random verification data in a short message manner, the encrypted random verification data can be prevented from being intercepted or tampered by a third-party device, so as to ensure the security of the data.

Step S705, the user node 602 obtains the short message sent by the operator node 601 through a short message channel in the mobile switching network, and obtains encrypted random verification data therein; the user node 602 decrypts the encrypted random verification data according to a predetermined algorithm by using its own private key, and obtains the data to be verified.

In step S706, the user node 602 generates a broadcast message according to the data to be verified, the own blockchain identifier (i.e., the first hash value) and the identity encryption result, signs the broadcast using its own private key, and generates and sends the signed broadcast message to the blockchain network, so that the operator node 601 verifies the user node 602 again.

Step S707, after receiving the broadcast message sent by the user node 602 from the blockchain network, the operator node 601 verifies a private key signature of the broadcast message, and obtains random verification data by querying its own user database when it is determined that the private key signature is verified, where the random verification data is data issued to the user 601 by the operator node 601 within a preset time period; comparing the random verification data with the data to be verified in the broadcast message to obtain a comparison result; if the comparison result is determined to be the same, it indicates that the user node 602 is verified again.

In some implementations, the operator node 601 generates a registration message according to the blockchain identifier and the identity encryption result of the user node 602, signs the registration message using its own private key, and generates and sends the signed registration message to the blockchain network, so that the user node 602 can register in the blockchain network.

For example, miners in the blockchain network may obtain broadcast messages sent by the user node 602 signed by their private key and may also obtain registration messages sent by the operator node 601 signed by their private key. The miners verify the private keys of the operator node 601 and the user node 602 respectively, and in a case that it is determined that the private keys of both the operator node 601 and the user node 602 pass the verification, the miners search the blockchain ledger to know that the blockchain identifier of the user node 602 is not stored in the blockchain ledger (that is, the identifier of the terminal used by the user node 602 is not registered in the blockchain network), and then write the registration information corresponding to the user node 602 (for example, the blockchain identifier of the user node 602, the public key of the user node 602, the identity encryption result, and the like) into the blockchain ledger, and have completed the registration of the user node 602.

The miners can inquire the public key of the operator node 601 through the created block of the block chain, and the public key of the user node 602 can be carried in the broadcast message sent by the miners; and then miners can verify the private keys of different nodes by using the corresponding public keys respectively. It should be noted that the identity of a terminal can only be registered once in the blockchain network,

in step S708, the operator node 601 obtains and forwards the medical request message sent by the user node 602 to the blockchain network, so that the hospital node 603 obtains the medical request message.

The medical request message may be a message signed by the private key of the user node 602, so as to ensure the security of the medical request message during transmission.

It should be noted that the hospital node 603 may store medical records and latest medical conditions of different users (for example, medical records of users in the last 6 months) in a database manner, and further, the hospital node 603 may also store identifiers of terminals used by different users and hash values obtained by performing hash operation on the identifiers of the terminals according to a preset algorithm, so as to facilitate subsequent searching of information of different users.

The medical request message includes: at least one of a blockchain identification of the user node 602, the first hash value, an identification of the hospital node 603, and an identification of the department included therein.

The first hash value is obtained by the user node 602 hashing historical check data (e.g., laboratory test report information, check report information, test result, check result, list of prescription, etc.). The first hash value is obtained by performing hash operation on the historical check data, so that the privacy information of the user node 602 can be protected from being leaked, and the security of the privacy information is ensured.

Step S709, after obtaining the medical request message from the blockchain network, the hospital node 603 verifies the private key signature of the medical request message, and if the verification is passed, obtains the historical check data corresponding to the blockchain identifier of the user node 602 by querying the database inside the hospital node. From this historical exam data, hospital node 603 may be made aware that user node 602 is a reviewing user who has been currently visited by hospital node 603 (e.g., patients who require periodic review within 5 years for hematology or long-term chemotherapy after bone marrow transplantation, etc.).

The hospital node 603 decrypts the current state information of the user node 602 in the medical request message according to a preset algorithm by using its own private key, obtains the current state information of the user node 602, and provides prescription information for the user node 602, where the prescription information includes: drug information and/or real-time exam information (e.g., laboratory test orders, exam orders, etc.); and then, the public key of the user node 602 is used for encrypting the prescription information according to a preset algorithm to generate the encrypted prescription information so as to ensure the safety of the prescription information. The current status information and the encrypted prescription information are then updated to the database of the hospital node 603 to facilitate subsequent examination of the user node 602.

In some specific implementations, the hospital node 603 may further perform hash operation on the encrypted prescription information to generate a second hash value, so as to avoid any tampering of the encrypted prescription information by a third-party device, and ensure the authenticity and validity of the prescription information.

In step S710, the hospital node 603 feeds back the encrypted prescription information and the blockchain identifier of the user node 602 to the operator node 601, so that the operator node 601 obtains the prescription information.

While step S710 is being performed, the hospital node 603 also performs step S711.

Step S711, the hospital node 603 generates and sends an reimbursement request message to the blockchain network according to the prescription information and the medical insurance information corresponding to the user node 602, so that the medical insurance node 604 obtains the reimbursement request message.

Wherein, the reimbursement request message includes: at least one of prescription information, medical insurance information corresponding to the user node 602, a blockchain identification of the user node 602, and a second hash value. The reimbursement request message may also be an encrypted message to ensure the security of the reimbursement request message during transmission.

Step S712, the medical insurance node 604 obtains the reimbursement request message sent by the hospital node 603 from the blockchain network, analyzes the reimbursement request message, and obtains the medical insurance information (e.g., the medical insurance type and reimbursement proportion of the user node 602) corresponding to the user node 602; then, calculating to obtain medical expense information corresponding to the prescription information according to the prescription information and the medical insurance information; the private key of the operator node 601 is used to encrypt the prescription information and the medical expense information, and an expense encryption result is obtained.

In some specific implementations, the hospital node 603 may further provide medical expense information according to the prescription information, and then send the medical expense information to the medical insurance node 604, so that the medical insurance node 604 may search the database of the medical insurance node 604 according to the medical insurance information of the user node 602, obtain information such as a medical insurance type, an reimbursement proportion, and an annual accumulated medical insurance expense corresponding to the user node 602, and check the medical expense information based on the information such as the medical insurance type and the reimbursement proportion corresponding to the user node 602 obtained from the database, to determine final expense information. To avoid errors in the medical expense information.

In step S713, the medical insurance node 604 sends the charge encryption result to the blockchain network, so that the operator node 601 can obtain the medical charge information of the user node 602.

Step S714, the operator node 601 obtains the expense encryption result fed back by the medical insurance node 604 from the block chain network, and decrypts the expense encryption result by adopting the public key of the operator node 601 to obtain the prescription information and the medical expense information of the user node 602; then, medical response information is generated based on the medical expense information, the prescription information obtained in step S710, and the blockchain identification of the user node 602.

In step S715, the operator node 601 signs the medical response information using the private key of the user node 602, and generates and sends the signed medical response information to the blockchain network, so that the user node 602 can obtain the prescription information and the medical expense information.

In step S716, the user node 602 interacts with the hospital node 603 through the blockchain network, and obtains the medicine required by the user node 602 according to the prescription information and the medical expense information.

After obtaining the signed medical response information sent by the operator node 601 from the blockchain network, the user node 602 verifies the private key signature of the signed medical response information, and when the verification is determined to be passed, the user node 602 obtains prescription information and medical expense information and pays medical expenses to the hospital node 603 according to the medical expense information (for example, transfers money to the hospital node 603, and the like); after the hospital node 603 obtains the medical cost, the hospital node 603 mails the medicine required by the user node 602 to the user node 602 according to the prescription information and the mailing address of the user node 602 found from the database, thereby implementing the internet-based medical process.

In some implementations, the operator node 601 may also write the second hash value, the first hash value, and the identity information of the user node 602 into the blockchain ledger. The second hash value is obtained by performing hash operation on prescription information by the hospital node 603, and the prescription information includes: drug information and/or real-time exam information.

In this embodiment, by writing the second hash value, the first hash value, and the identity information of the user node 602 into the blockchain account book, corresponding medical evidence can be provided in the case of medical dispute, and the security of the prescription information and the medical expense information and the information accuracy of the user node 602 can be ensured by the first hash value and the second hash value. In the interaction process of the medical information, the blockchain network is adopted to record and transmit the medical information and the identity information of the user node, so that the possibility of tampering the information of the user can be reduced, and the information security of the user can be protected; moreover, the user node can use the medical insurance information to complete the Internet-based medical treatment process, so that the medical cost of the user node is reduced, the use experience of the user is improved, the development and popularization of an Internet inquiry method are facilitated, the medical treatment pressure of a hospital is relieved, and a convenient and safe medical treatment method is provided for the user.
