Fig. 2 is a schematic flow chart illustrating a remote medical information processing method according to another embodiment of the present application. The method can be applied to a first operator node in a block chain network, and the block chain network further comprises a second operator node, a user node, a hospital node and a medical insurance node, wherein the second operator node provides communication service for the user node. As shown in fig. 2, the remote medical information processing method includes the following steps.
Step S201, the identity information of the user node is verified, and a first verification result is obtained.
The identity information of the user node comprises: identification of the terminal used by the user node. 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, a second encryption result fed back by the second operator node is obtained.
And the second encryption result is obtained by encrypting the random verification data by the second operator node according to the service password corresponding to the terminal used by the user node and a preset algorithm.
Step S203, in a case that the first verification result is determined to be verification pass, generating and sending a broadcast message to the blockchain network according to the randomly generated random verification data and the blockchain identifier of the user node, so that the second operator node and the user node obtain the random verification data.
Before the broadcast message is sent, the random verification data in the broadcast message can be encrypted, and the encrypted random verification data is packaged into the broadcast message, so that the safety of the random verification data is improved.
Step S204, a first encryption result fed back by the user node is obtained from the block chain network.
The first encryption result is obtained by encrypting the random authentication data by the user node according to the service password of the second operator and a preset algorithm.
Step S205, comparing the first encryption result and the second encryption result to obtain a comparison result.
Wherein, the comparison result comprises that the first encryption result is the same as the second encryption result, or the first encryption result is different from the second encryption result.
In step S206, a second verification result is determined according to the comparison result.
When the comparison result is that the first encryption result is the same as the second encryption result, determining that the second verification result is that the user node is verified to be passed; otherwise, when the comparison result is determined to be that the first encryption result and the second encryption result are different, the second verification result is determined to be that the user node is not verified.
Step S207, in a case that it is determined that both the first verification result and the second verification result are 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 S207 in this embodiment is the same as step S104 in the previous embodiment, and is not repeated herein.
And step S208, generating and sending a medical response message to the blockchain network according to the identity information of the user node, the prescription information fed back by the hospital node and the medical expense information fed back by the medical insurance node, which are 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.
The reimbursement proportions corresponding to different medical insurance types are different, and the corresponding available preset medical insurance cost information is different 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 still another possible implementation manner, where before performing step S104 or step S207, 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 implementations, the first operator node and the second operator node communicate through core network equipment; step S203 can also be implemented as follows: signing the random verification data and the block chain identifier of the user node by using a private key of a first operator node, generating and sending a signature message to a block chain network so as to enable the user node to obtain the random verification data; generating a message to be processed according to the random verification data and the block chain identification of the user node; and sending the message to be processed to the core network equipment.
The core network equipment forwards the message to be processed to the second operator node, so that the second operator node obtains the random verification data, information leakage caused by interception and capture of the random verification data by third-party equipment during transmission in the network can be avoided, and the transmission safety of the random verification data can be ensured.
The embodiment of the present application provides another possible implementation manner, and after performing step S105 or step S208, 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.

Fig. 7 shows a flowchart of a working method of the telemedicine information processing system provided by the embodiment of the application. As shown in FIG. 7, the method of operation of the telemedicine 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 first operator node 601 from the blockchain network, and encrypts the identity information of the user node 602 using the public key of the first 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 first 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 first operator node 601, and generates and sends the signed authentication message to the blockchain network, so that the first operator node 601 obtains the authentication message.
Step S703, after obtaining the signed authentication message from the blockchain network, the first 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 is passed; then, according to a preset algorithm, the private key of the first operator node 601 is used to decrypt the identity encryption result, and the identity information of the user node 602 is obtained.
Further, the first operator node 601 queries the database according to the identity information of the user node 602, and determines that the identifier (e.g., a mobile phone number) of the terminal used by the user node 602 is not in its service identifier list, but the second operator node 605 provides a communication service for the terminal used by the user node 602.
In step S704, the first operator node 601 randomly generates a random authentication data, and generates and sends a broadcast message to the blockchain network based on the random authentication data and the blockchain identifier of the user node 602, so that both the user node 602 and the second operator node 605 can obtain the random authentication data.
In some implementations, the second operator node 605 may obtain the random authentication data through a forwarding operation of the core network device and an industry gateway of the second operator node 605.
In step S705, the user node 602 encrypts the obtained random authentication data by using a pre-stored customer service password of the second operator node 605 and using a preset algorithm, and generates a first encryption result. The user node 602 signs the first encryption result, the blockchain identifier of the user node 602, and the public key using its own private key, and generates and sends a signed message to the blockchain network, so that the first operator node 601 can obtain the first encryption result fed back by the user node 602.
It should be noted that, while step S705 is executed, step S706 is also executed between the second operator node 605 and the first operator node 601.
In step S706, after obtaining the random authentication data in step S704 and the identifier of the terminal used by the user node 602, the second operator node 605 encrypts the random authentication data according to the customer service password and the preset algorithm, and obtains and sends a second encryption result to the blockchain network, so that the first operator node 601 obtains the second encryption result.
In some specific implementations, the second encryption result obtained by the second operator node 605 and the identifier of the terminal used by the user node 602 may also be forwarded to the first operator node 601 through the core network device and the industry gateway of the second operator node 605.
Step S707, after obtaining the first encryption result fed back by the user node 602 and the second encryption result fed back by the second operator node 605, the first operator node 601 compares the first encryption result with the second encryption result, and if the two encryption results are the same, it indicates that the user node 602 is verified again; otherwise, it is determined that the user node 602 is not authenticated.
Under the condition that the user node 602 is determined to pass the verification again, the first 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 by using a private key of the first operator node, and generates and sends the signed registration message to the blockchain network, so that the user node 602 can register in the blockchain network.
In some implementations, 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 first operator node 601 signed by their private key. The miners verify the private key of the first operator node 601 and the private key of the user node 602 respectively, and in a case that it is determined that the private keys of both the first operator node 601 and the user node 602 are verified, 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 and the identity encryption result of the user node 602, 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 first 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 first 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.
