Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness. It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.

In the embodiment of the invention, the doctor can diagnose the disease condition of the patient based on the block chain technology. The block chain is an integrated innovation application mode of computer technologies such as fused distributed storage, point-to-point data transmission, a consensus mechanism and an encryption algorithm. In general, a blockchain is an organization structure of information resources, and is logically a linked list formed by one or more blocks, where the blocks are used to store one or more information resources such as transaction records and intelligent contracts, and each node in a blockchain-based distributed network (hereinafter referred to as a blockchain network) holds the same blockchain, and the blockchain network is composed of the nodes holding blockchains.

The block chain can be divided into a public chain, a private chain and a alliance chain according to the application range and different node admission objects. Wherein: public chains are open to all people on the internet, such as bitcoin, ether house. Private chains are typically used inside organizations and are not open to others. Federation chains are open to specific organizations and enterprises. Some of the terms appearing in the examples of the present invention are explained below:

consensus: block chain terminology. There is no single accounting center on the blockchain, and the ledgers are recorded jointly by the whole network, which raises a problem of how to determine whether a transaction is legal. The process of determining whether a transaction is legal and whether a block of packages recommended by a node is approved by everyone is called consensus, and only blocks passing the consensus are approved by the whole network.

Intelligent contract: a piece of program code on the blockchain specifies the rights and obligations of the contractual associate and the terms of the action. Contract associates confirm smart contracts by sending blockchain transactions, paying for digital currency that the contracts may require, invoking functions specified by the smart contracts, and the like.

Fig. 1 is a schematic diagram of main steps of a diagnosis method based on a blockchain network in an embodiment of the present invention, and as shown in fig. 1, the diagnosis method based on a blockchain network in an embodiment of the present invention may specifically perform the following steps:

step S101: and the patient terminal stores medical record information of the patient, writes the medical record information into the block chain maintained by each node of the block chain network, and sends a treatment message to the target doctor terminal.

In an embodiment of the invention, the blockchain network is a computer network consisting of a plurality of network nodes, including a patient terminal and a doctor terminal. In some embodiments, the network node may also comprise a hospital terminal. It is understood that the patient terminal is a terminal used by a patient, the doctor terminal is a terminal used by a doctor, and the hospital terminal is a terminal used by a hospital, and the terminals can be various computing devices such as a smart phone, a tablet computer, a laptop portable computer, a desktop computer, and the like. In specific applications, the terminal generally needs to execute the diagnosis method according to the embodiment of the present invention through a corresponding application program (e.g., an application program on a desktop computer, an APP on a smart phone) set in the terminal. Fig. 2 is a schematic structural diagram of a blockchain network according to an embodiment of the present invention, and as shown in fig. 2, a plurality of patient terminals and doctor terminals may be connected to each other based on any network connection type to form a blockchain network, and each patient terminal and each doctor terminal store the same blockchain therein. In practical applications, the above blockchain network may be a public-chain network.

As a preferred scheme, before executing step S101, the patient terminal, the doctor terminal and the hospital terminal may first enter the parking block chain network through the parking process. Fig. 3 is a schematic flow chart of the method for a patient terminal to enter a dwell blockchain network according to an embodiment of the present invention, and as shown in fig. 3, the patient terminal first stores identification information and payment route information provided by a patient. Illustratively, the identification information of the patient may include at least one of: the name, identification number, mobile phone number, and facial features extracted through a preset algorithm or model, and in some embodiments, the name, identification number, mobile phone number, and facial features may also include age, gender, and the like. The payment route information of the patient may include bank account information (e.g., a bank card number) of the patient or electronic account information such as a payment treasure, a WeChat, and the like. In step S301, the patient terminal invokes a corresponding interface of an authentication system (e.g., a national resident identity information system) to verify the identification information such as the name, the identification number, the face feature, and the like of the patient, and if the verification is passed, the subsequent steps are executed, otherwise, the process is ended. In step S302, the patient terminal invokes a payment verification system (e.g., a bank card center) to verify payment route information such as a bank card number of the patient, and if the payment verification system can determine a binding relationship between the payment route information such as the bank card number and the patient, a subsequent process is executed, otherwise, the process is ended.

In step S303, the patient terminal encrypts the identification information and the payment route information of the patient, where the encryption type may be symmetric encryption or asymmetric encryption, and the asymmetric encryption will be described as an example below. In this step, the patient terminal may randomly generate a paired public key and private key according to an intelligent contract pre-deployed in the blockchain, and encrypt the identification information and payment route information of the patient using the private key. In a specific application, the encryption generally needs to combine the identification information and the payment route information of the patient with the current timestamp for encryption. In step S304, the patient terminal calculates third index data for referring to the encrypted data based on the encrypted data of the patient identification information and the payment route information, for example, a hash value corresponding to the encrypted data as the third index data. In step S305, the patient terminal writes the encrypted data and the third index data into the blockchain. It should be noted that the process of writing the relevant data into the blockchain includes that the data reaches a consensus in the whole blockchain network and is synchronized to each node of the blockchain network, and any consensus mechanism such as PoW (Proof of workload), PoS (Proof of rights and interests), etc. may be adopted. In step S306, the patient terminal stores the third index and a third key for decrypting the encrypted data (i.e., the public key paired with the private key used by the encryption identification information and the payment route information) locally. It is understood that the patient terminal may subsequently obtain the encrypted data from the blockchain through the third index data, and obtain the identification information and payment route information of the patient from the encrypted data by using the third key.

Fig. 4 is a schematic flow chart of a doctor terminal entering a resident block chain network in an embodiment of the present invention, and as shown in fig. 4, the doctor terminal first stores identification information, payment route information, and authentication information provided by a doctor. Illustratively, the identification information of the doctor may include at least one of: the name, identification number, mobile phone number, and facial features extracted through a preset algorithm or model, and in some embodiments, the age, sex, and the like of the doctor may also be included. The payment route information of the doctor may include bank account information (e.g. a bank card number) of the doctor or electronic account information such as a payment treasure, a WeChat, etc., and the authentication information of the doctor may include medical practice hospital information (e.g. a hospital name) where the doctor is located and medical practice certificate information (which may include a certificate number, a medical practice range, etc.).

In step S401, the doctor terminal invokes a corresponding interface of an identity verification system (e.g., a national resident identity information system) to verify the identification information such as the name, the identification number, the face feature, and the like of the doctor, and if the verification is passed, the subsequent steps are executed, otherwise, the flow is ended. In step S402, the doctor terminal calls a corresponding interface of a qualification verification system (e.g., a national health commission official website) to verify the authentication information of the doctor. In practical applications, the doctor terminal may verify the licensed hospital information in the doctor authentication information according to the verified hospital information written in the blockchain in advance, and the content of writing the hospital information in the blockchain will be described below. In step S403, the doctor terminal invokes a payment verification system (e.g., a bank card center) to verify payment route information such as a bank card number of the doctor, and if the payment verification system can determine a binding relationship between the payment route information such as the bank card number and the doctor, a subsequent process is executed, otherwise, the process is ended.

In step S404, the doctor terminal encrypts the doctor' S identification information, payment route information and authentication information, and the encryption type may be symmetric encryption or asymmetric encryption. In a specific application, during encryption, identification information, payment route information and authentication information of a doctor are generally required to be combined with a current timestamp for encryption. In step S405, the doctor terminal calculates fourth index data for querying the encrypted data based on the encrypted data of the doctor identification information, the payment route information, and the authentication information, for example, taking a hash value corresponding to the encrypted data as the fourth index data. In step S406, the doctor terminal writes the encrypted data and the fourth index data into the block chain. In step S407, the doctor terminal stores the fourth index and a fourth key (for example, a public key paired with a private key used for the encrypted identification information, the payment route information, and the authentication information) for decrypting the encrypted data described above locally. It can be understood that the doctor terminal can subsequently obtain the encrypted data from the blockchain through the fourth index data, and obtain the identification information, payment route information and authentication information of the doctor from the encrypted data by using the fourth key.

Fig. 5 is a schematic flow chart of a hospital terminal entering a block chain network according to an embodiment of the present invention, and as shown in fig. 5, the hospital terminal first stores qualification information and payment route information provided by a doctor. Illustratively, the qualification information for the hospital may include at least one of: hospital name, business license information, hospital grade, legal representative, contact phone number, and payment route information of the hospital may include bank account information (such as bank card number) of the hospital or electronic account information such as payment treasure, WeChat, and the like.

In step S501, the hospital terminal calls a corresponding interface of a qualification verification system (e.g., a national health commission official website) to check qualification information of the hospital. In step S502, the hospital terminal invokes a payment verification system (e.g., a bank card center) to verify payment route information such as a bank card number of the hospital, and if the payment verification system can determine a binding relationship between the payment route information such as the bank card number and the hospital, a subsequent process is executed, otherwise, the process is ended. In step S503, the hospital terminal encrypts the qualification information and the payment route information of the hospital, and the encryption type may be symmetric encryption or asymmetric encryption. In a specific application, the hospital qualification information and the payment route information are generally required to be encrypted together with the current time stamp during encryption. In step S504, the hospital terminal calculates sixth index data for querying the encrypted data based on the encrypted data of the hospital qualification information and the payment route information, for example, taking a hash value corresponding to the encrypted data as the sixth index data. In step S505, the hospital terminal writes the encrypted data and the sixth index data into the block chain. In step S506, the hospital terminal stores the sixth index and a sixth key (for example, a public key paired with a private key used for encrypting the certification information and the payment route information) for decrypting the encrypted data described above locally. It is to be understood that the hospital terminal may subsequently obtain the above encrypted data from the blockchain through the sixth index data, and obtain the qualification information and payment route information of the hospital from the encrypted data by using the sixth key. The hospital that has performed steps S501 to S505 is a verified hospital, and the verified hospital information written in the blockchain may be used to verify the medical hospital information in the authentication information provided by the doctor.

In step S101, the patient terminal stores medical record information provided by the patient, writes the medical record information into the block chain, and sends a visit message to the target doctor terminal. The medical record information may include one or more of the following: patient symptom information, historical visit data (e.g., diagnostic procedures and results at a physical hospital, which may also be directly obtained from a corresponding interface provided at the hospital), imaging examination data (e.g., color Doppler, CT image data, various laboratory sheets such as blood routine, biochemical data, etc., CT representing computed tomography). The target doctor terminal can be a terminal used by a doctor appointed by the patient, or can be a terminal used by a doctor automatically recommended to the patient based on medical record information according to an intelligent contract pre-deployed in the block chain.

As a preferred scheme, after storing medical record information provided by a patient, the patient terminal may query encrypted data of patient identification information and payment route information from the blockchain by using third index data stored in advance locally, and decrypt the encrypted data by using a third key stored in advance locally to obtain the patient identification information and payment route information, and thereafter, the patient terminal may compare whether the patient identification information is consistent with corresponding data of the medical record information to verify the medical record information, for example, compare whether the identification information is consistent with data of name, gender, age, and the like in the medical record information. And when the verification is passed, the subsequent flow can be executed, otherwise, the flow is ended.

In practical application, after the patient terminal stores the medical record information, the encrypted data of the medical record information and the first index data for querying the encrypted data can be written into the block chain. Wherein the first index data may be a hash value of the encrypted data. In this case, the visit message sent by the patient terminal to the target doctor terminal may carry the first index data and a first key (e.g., a public key paired with a private key used to encrypt medical record information) for decrypting the encrypted data. It can be understood that the target doctor terminal can subsequently obtain the medical record information of the patient according to the first index data and the first key.

Preferably, if the medical record information of the patient includes the image examination data of the patient, the patient terminal may invoke a first intelligent contract pre-deployed in the blockchain to detect the image examination data after storing the medical record information to obtain an image detection result. The first intelligent contract comprises corresponding algorithms of image processing and target identification, can detect targets such as nodules and the like and provide related information such as target size and position, and through the arrangement, reference opinions can be provided for diagnosis of a doctor, time and energy consumed by the doctor for viewing image examination data are reduced, and diagnosis and treatment efficiency is improved. Thereafter, the patient terminal may package and encrypt the medical record information and the image detection result (in practical applications, the current timestamp may also be combined), and write the encrypted data and the first index data for querying the encrypted data into the blockchain. In some embodiments, the data encrypted and written into the blockchain may include patient identification information and payment route information in addition to the medical record information, the image detection result, and the current timestamp, the patient identification information may be used for further identity verification performed by the doctor terminal, and the payment route information may be used to support a subsequent payment process. In one embodiment, after the patient terminal performs the visit process, the payment of the service fee can be performed according to the payment rule specified by the corresponding intelligent contract, after the payment is completed, the payment result can be written into the block chain, and the related service fee can be transferred according to the payment route information of the corresponding doctor.

Fig. 6 is a schematic diagram of a patient treatment process in an embodiment of the present invention, and as shown in fig. 6, in step S601, the patient terminal obtains encrypted data of patient identification information and payment route information from the blockchain according to the third index data, and performs decryption by using the third key to obtain the identification information and the payment route information of the patient. In step S602, the patient terminal compares the patient identification information with the relevant data in the medical record information to verify the medical record information. In step S603, the patient terminal invokes the first intelligent contract to detect the image inspection data in the medical record information, so as to obtain an image detection result. In step S604, the patient terminal encrypts the medical record information and the image detection result. In step S605, the patient terminal takes the hash value of the encrypted data as first index data. In step S606, the patient terminal writes the encrypted data and the first index data into the blockchain. In step S607, the patient terminal sends the visit message carrying the first index data and the first key to the target doctor terminal.

Step S102: and the patient terminal receives the diagnosis completion message sent by the target doctor terminal. The diagnosis completion message is sent after the target doctor terminal writes the diagnosis result made by the doctor based on the medical record information of the patient into the blockchain, and the medical record information is acquired from the blockchain by the target doctor terminal after receiving the treatment message.

In this step, after receiving the visit message, the target doctor terminal may query encrypted data of the medical record information from the blockchain according to the first index data in the visit message (in some embodiments, the encrypted data may also be encrypted data of the medical record information and the image detection result, and may also be encrypted data of the medical record information, the image detection result, the patient identity information, and the payment route information), and decrypt the encrypted data with the first key in the visit message to obtain the medical record information, or the medical record information and the image detection result, or the medical record information, the image detection result, the patient identity information, and the payment route information. After the target doctor terminal acquires the patient identity information, the patient identity information and related data such as name, age, sex and the like in the medical record information can be further verified to ensure that the diagnosis information is correct.

Thereafter, the target doctor terminal can store the diagnosis result made by the doctor based on the medical record information or the medical record information and the aforementioned image detection result. Particularly, the doctor can only send out voice without writing a diagnosis result during diagnosis, and the target doctor terminal can call a second intelligent contract which is deployed in the blockchain in advance to convert the doctor voice into the diagnosis result in a text format and store the diagnosis result. It will be appreciated that the second intelligent contract includes a corresponding algorithm for converting speech to text. Through above setting, can further improve and diagnose efficiency.

In the embodiment of the invention, after the target doctor terminal stores the diagnosis result, the encrypted data of the diagnosis result and the second index data for inquiring the encrypted data can be written into the block chain. In this case, the diagnosis completion message sent by the target doctor terminal to the patient terminal may carry the second index data and a second key (e.g., a public key paired with a private key used to encrypt the diagnosis result) for decrypting the encrypted data. After receiving the diagnosis completion message, the patient terminal can obtain a diagnosis result according to the second index data and the second key, thereby completing the diagnosis process.

In an alternative scheme, after receiving the diagnosis completion message, the patient terminal may query the encrypted data of the diagnosis result from the blockchain according to the second index data in the diagnosis completion message, and decrypt the encrypted data with the second key in the diagnosis completion message to obtain the diagnosis result. Thereafter, when the patient makes a decision on acceptance, the patient terminal may store acceptance information. Generally, the acceptance information may indicate whether the patient accepts the diagnosis result, and if the patient refuses to accept the diagnosis result, the acceptance information may further include refusal reason information. Thereafter, the patient terminal may write the encrypted data of the acceptance information and fifth index data (which may be a hash value of the encrypted data) for querying the encrypted data into the blockchain, and send a response message to the target doctor terminal, where the fifth index data and a fifth key (for example, a public key paired with a private key used for encrypting the acceptance information) for decrypting the encrypted data of the acceptance information may be carried in the response message.

As an alternative, when the acceptance information indicates that the patient accepts the diagnosis result, the patient terminal may pay according to a corresponding intelligent contract pre-deployed in the block chain, that is, interact with a corresponding institution (e.g., a bank) by using the payment route information and perform procedures such as identity authentication, thereby implementing money transfer. For example, the patient terminal may first freeze the deposit in the patient's bank card, and then deduct the money according to the rules defined by the smart contract (the identity of the payee may also be authenticated during deduction), where the deducted money may include service fees, drug fees, and subsequent check fees. After the payment is completed, the patient terminal may encrypt the payment result into the blockchain and send a payment completion message to the target doctor terminal. After the patient performs the payment process based on his terminal, subsequent drug collection, further examination, etc. may be performed. It should be noted that the above payment process may be executed in parallel with the process of writing the acceptance information into the block chain, or may be executed according to any sequence, which is not limited in the present invention.

After receiving the response message, the target doctor terminal inquires the encrypted data of the acceptance information from the blockchain according to the fifth index data carried in the response message, and decrypts the encrypted data by using the fifth key in the response message to obtain the acceptance information of the patient. If the acceptance information indicates that the patient accepts the diagnosis result, the target doctor terminal may receive a payment completion message transmitted from the patient terminal, and after receiving the message, the target doctor terminal may charge a corresponding money (e.g., a service fee) based on a corresponding intelligent contract. It will be appreciated that the cost of the medication, the cost of follow-up examinations, etc. may be collected by the hospital terminal through interaction of the patient terminal with the hospital terminal. In a specific application, when a doctor diagnoses a plurality of patients, the doctor terminal can preferentially process medical record information of historical patients, and can also process medical record information of each patient according to a time sequence. During the diagnosis process, the doctor can select whether to start the video visit with the patient.

Fig. 7 is a schematic view of a doctor diagnosis process in the embodiment of the present invention, and as shown in fig. 7, in step S701, the target doctor terminal acquires medical record information of the patient or medical record information and an image detection result from the block chain. In step S702, the target doctor terminal stores a diagnosis result obtained by the doctor based on the medical record information or the medical record information and the image detection result. In particular, the diagnosis result may be a text generated by the doctor's voice by the target doctor's terminal invoking the second smart contract. In step S703, the target doctor terminal encrypts the diagnosis result. In step S704, the target doctor terminal takes the hash value of the encrypted data as second index data. In step S705, the target doctor terminal writes the encrypted data and the second index data into the block chain. In step S706, the target doctor terminal transmits a diagnosis completion message to the corresponding patient terminal. In step S707, the patient terminal stores the reception information provided by the patient. In step S708, the patient terminal encrypts the reception information. In step S709, the patient terminal takes the hash value of the encrypted data as fifth index data. In step S710, the patient terminal writes the encrypted data and the fifth index data into the blockchain. In step S711, the patient terminal transmits a response message to the target doctor terminal. In step S712, if the acceptance information indicates that the patient accepts the diagnosis result, the patient terminal automatically performs payment according to the corresponding smart contract. In step S713, the patient terminal writes the payment result to the blockchain. In step S714, the patient terminal transmits a payment completion message to the target doctor terminal. In step S715, the target doctor terminal acquires the acceptance information from the blockchain. In step S716, the target doctor terminal obtains the payment result from the blockchain and performs a collection action.

In practice, after the patient is treated for a period of time based on the diagnosis made by the doctor, the patient may give feedback to the doctor. Specifically, the patient terminal may store evaluation information of the patient on the doctor, adjust the score and/or the level of the doctor according to the evaluation information and a third intelligent contract pre-deployed in the blockchain, and finally write the adjusted score and/or level into the blockchain. It will be appreciated that the above data may be written to the blockchain after encryption. Through the above arrangement, dynamic consideration of the doctor's diagnosis level can be realized based on patient evaluation. In an actual scene, the patient terminal can also propose a double-check or change other doctors for the same doctor according to the corresponding intelligent contract and the evaluation information. In order to avoid the malicious evaluation of individual patients, corresponding rules can be set in the intelligent contract, for example, patients with poor evaluation frequency or proportion larger than a threshold value are added into a blacklist. Fig. 8 is a schematic diagram of a patient feedback process in an embodiment of the present invention, and as shown in fig. 8, in step S801, a patient terminal stores evaluation information provided by a patient. In step S802, the patient terminal invokes a third intelligent contract to adjust the doctor' S score or level. In step S803, the patient terminal writes the adjusted doctor score or rank into the block chain.
