The patient's personal information includes, but is not limited to, name and identification card. The predetermined algorithm may be any suitable hash algorithm, and the hash algorithm is not limited in this embodiment.

In some embodiments, the originating node receives a first complimentary broadcast message broadcast by a complimentary node in a blockchain.

a second generating module 701, configured to generate the donor node blockchain identifier by a pre-agreed hash algorithm based on the personal information of the patient.

In this embodiment, the gifted node blockchain identifier is a unique identifier of the gifted node in the blockchain. The patient's personal information includes, but is not limited to, the patient's name and identification card.

In the apparatus for establishing a bone marrow type blockchain provided in this embodiment, the second generating module of the given node generates a given node blockchain identifier based on personal information of a patient through a predetermined hash algorithm, the second obtaining module uses a private key of the given node to sign the given node blockchain identifier and a public key of the given node to obtain a first given broadcast message, and broadcasts the first given broadcast message in the blockchain, so that the originating node writes the given node blockchain identifier into a blockchain account based on the given node blockchain identifier and the public key of the given node to complete establishment of the bone marrow type blockchain.

In addition, each module in the above embodiments is a logical module, and in practical applications, one logical unit may be one physical unit, may be a part of one physical unit, and may be implemented by a combination of a plurality of physical units. In addition, in order to highlight the innovative part of the present invention, elements that are not so closely related to solving the technical problems proposed by the present invention are not introduced in the present embodiment, but this does not indicate that other elements are not present in the present embodiment.

In order to better understand the technical solution of the present application, a method for establishing a bone marrow matching block chain is described below based on a recipient node, a donor node, a timestamp server node, and a starting node.

As shown in fig. 8, the method for establishing the marrow type block chain includes:

step S801, the donor node encrypts its contact information using the public key of the originator node to obtain the donor encryption result.

Wherein the donor node may obtain the public key of the originator node from the founder block query. The contact details of the donor include, but are not limited to, the donor's phone, address, etc. information.

In this embodiment, in order to save the electric quantity and the storage space of the terminal used by the donor, after the donor node is connected to the current block chain, only the first generative block of the ledger of the current block chain needs to be synchronized, and not all the ledgers of the current block chain need to be synchronized.

The embodiment encrypts the contact information of the donor by using the public key of the originating node, so as to ensure the privacy of the personal information of the donor.

Step S802, the donation node performs HASH calculation on the personal information according to a predetermined algorithm to obtain a HASH value HASH-A1 as a donation node block chain identifier.

Personal information includes, but is not limited to, name and identification card. The predetermined algorithm may be any suitable hash algorithm, and the hash algorithm is not limited in this embodiment.

Because the ID card number of the donor has uniqueness, the HASH value HASH-A1 obtained based on the ID card number has uniqueness in the current block chain, and the donor node takes the HASH value HASH-A1 as the unique identifier of the donor node in the block chain, namely the donor node block chain identifier HASH-A1, so that the block chain identifier of the bone marrow donor node is prevented from generating a repeated phenomenon in the block chain.

In step S803, the donor node signs the donor node block chain identifier HASH-A1 and the donor node public key using the donor node private key, and obtains a first donor broadcast message.

In step S804, the donor node broadcasts the first donation broadcast message in the blockchain.

Step S805, after the originating node receives the first donation broadcast message, the originating node extracts the donation node public key from the first donation broadcast message, verifies the signature of the donation node private key, queries the block chain ledger if the verification passes, and writes the corresponding relationship between the donation node block chain identifier HASH-A1 and the donation node public key into the block chain ledger if it is determined that the donation node block chain identifier is not registered. In the event that it is determined that the donor node blockchain identification has been registered, the donor is denied registration with the blockchain.

In this embodiment, the blockchain ledger is queried to determine whether the blockchain identifier of the donor node has been registered, so as to ensure that each donor is registered only once, thereby preventing one donor from obtaining multiple registration identities, i.e., ensuring the uniqueness of the donor in the blockchain.

In step S806, the originating node returns the result of passing the verification to the donor node.

Step S807, the donor nodes sort the gene point location information of the donors according to a predetermined sequence, perform Hash calculation on the gene point location information to obtain corresponding donor gene Hash values HASH-A2, and then sign the block chain identifiers HASH-A1, HASH-A2 and the encryption results of the donors by using the private keys of the donors to obtain a second donor broadcast message.

The gene site location information may be important gene site location information, for example, ten important gene site location information are adopted, and the ten important gene site location information are sorted according to a predetermined sequence.

In this embodiment, the genetic point location information of the donor is not directly broadcast in the blockchain, but the hash value based on the genetic point location information is broadcast in the blockchain, so that not only the privacy of the donor can be protected, but also the biological crime research can be avoided after lawbreakers obtain the genetic point location information.

At step S808, the donor node broadcasts a second donation broadcast message in the blockchain.

Step S809, after the originating node receives the second donation broadcast message, verifying the private key signature of the donor, and writing the donation node block chain identifier HASH-A1, the gene HASH value HASH-A2, and the donor encryption result into a new block under the condition that the verification is passed, thereby writing into the block chain account book.

The private key signature may be verified in any suitable manner, which is not limited in this embodiment.

It should be noted that, this embodiment only describes how the donor writes the information such as the contact information and the gene into the blockchain account book in an encrypted manner by taking the donor as an example, but the embodiment is not limited thereto. In fact, any donor can also write the information of the respective contact addresses, genes, etc. into the blockchain ledger through steps S801 to S809 in an encrypted manner, that is, the blockchain ledger stores a large amount of information of the contact addresses, genes, etc. of the donors.

It should be further noted that after the donor uploads the information such as the contact information and the gene to the blockchain, the account book information of the blockchain is not required to be synchronized in real time, but the donor can be operated offline until the donor receives the wake-up information. The wake-up message may be a phone or a mail of the originator, or may also be other ways to notify the donor to go online, which is not limited in this embodiment.

And step S810, the gifted node performs HASH calculation on the personal information according to a pre-agreed algorithm to obtain a HASH value HASH-AA1 as a gifted node block chain identifier.

The personal information of the patient includes, but is not limited to, the name and identification card of the patient. The predetermined algorithm may be any suitable hash algorithm, and the hash algorithm is not limited in this embodiment.

Because the identity card number of the patient has uniqueness, the HASH value HASH-AA1 obtained based on the identity card number has uniqueness in the current block chain, and the patient uses the HASH value HASH-AA1 as the unique identifier of the patient in the block chain, namely the block chain identifier HASH-AA1 of the donated node, so that the block chain identifier of the patient is prevented from being repeated in the block chain.

In step S811, the gifted node signs the gifted node block chain identifier HASH-A1 and the gifted node public key using the gifted node private key to obtain a first gifted broadcast message.

In step S812, the gifted node broadcasts the first gifted broadcast message in the block chain.

Step S813, after receiving the first given broadcast message, the originating node extracts the public key of the given node from the first given broadcast message, verifies the signature of the private key of the given node, queries the block chain ledger if the verification passes, and writes the corresponding relationship between the block chain identifier HASH-AA1 of the given node and the public key of the given node into the block chain ledger if the block chain identifier of the given node is determined not to be registered. In the event that it is determined that the recipient node blockchain identification has been registered, the donor node is denied registration with the blockchain.

Step S814, the donated node synchronizes all the account book information of the current block chain, sorts the gene point location information according to a predetermined sequence, and performs HASH calculation on the gene point location information to obtain a corresponding patient gene HASH value HASH-AA2.

According to the method, the gene point location information of the patient is not directly broadcast in the block chain, but the hash value based on the gene point location information is broadcast in the block chain, so that the privacy of the patient can be protected, and the biological crime research can be avoided after lawbreakers obtain the gene point location information.

Step S815, the recipient node queries the block chain account book, and obtains the gene point location information of the donor matched with the gene point location information of the recipient node, that is, obtains the donor gene HASH value HASH-A2 corresponding to the patient gene HASH value HASH-AA2 based on the patient gene HASH value HASH-AA2.

In step S816, the recipient node signs the block chain identifier HASH-A1, the donor gene HASH value HASH-A2, and the donor encryption result of the donor in the second donation broadcast message using its own private key, and obtains a second recipient broadcast message.

In this embodiment, since the second given broadcast messages all carry timestamps, the sequence of the second given broadcast messages issued by the patients can be distinguished by using the timestamps, and it is possible to avoid that different patients requiring the same assignment challenge request time are unfair and compete for bone marrow assignment resources, thereby avoiding unnecessary disputes.

Step S817, the donated node sends the second donated broadcast message to the timestamp server.

In step S818, the timestamp server signs and marks the timestamp on the second gifted broadcast message by using its own private key, and the gifted node sends the second gifted broadcast message carrying the timestamp to the originating node.

In step S819, the timestamp server returns the second gifted broadcast message carrying the timestamp to the gifted node.

Step S820, after the originating node receives the second donated broadcast message, the recipient node public key is queried in the block chain account book through the recipient node block chain identifier HASH-AA1, the recipient node private key in the second donated broadcast message is verified by using the recipient node public key, and under the condition that the verification is passed, the donation node block chain identifier HASH-A1, the donator gene HASH value HASH-A2, and the donator encryption result are obtained. The originating node decrypts the encrypted result of the donor according to a predetermined algorithm by using a private key of the originating node, and obtains the contact way of the donor.

In step S821, the originating node notifies the donor of the online.

It should be noted that, in this embodiment, the donor may be notified to go online through a telephone notification manner, or may be notified to go online through other manners, and the manner of notifying the donor to go online is not limited in this application.

In this embodiment, after uploading the genetic information and the contact information of the donor to the blockchain, the donor may not find a patient that can be matched with the donor for several years or even for life, and if the donor is online all the time, unnecessary consumption of electric power and flow is easily caused.

Step S822, after the donation node receives the online notification, if the donation node still agrees to donate, the online block chain is started, the private key of the donation node is used for signing the message agreeing to donation and the donation amount of the donation price, a third donation broadcast message is obtained, and the third donation broadcast message is broadcast in the block chain.

Wherein the donation price amount is the price the donor proposes for the bone marrow donation, i.e., the desired return.

Step S823, after the donated node receives the third donation broadcast message, the donated node verifies the private key of the donated node by using the public key of the donated node, and under the condition that the verification is passed and the donator is agreed, the donated node signs the thank you information by using its private key to obtain a second donated broadcast message.

Wherein the thank you message is information that the patient thank you donor donates bone marrow to himself. The medical costs may be provided to the donor by money transfer, etc.

In step S824, the donated node broadcasts the second donated broadcast message in the blockchain, and sends the physical examination cost to the donating node.

Step S825, after the donor is subjected to physical examination, encrypting the physical examination report by using the public key of the patient according to a predetermined algorithm, signing the encrypted physical examination report by using the private key of the donor, obtaining a fourth donation broadcast message, and broadcasting the fourth donation broadcast message in the block chain.

In order to protect the privacy of the donor and prevent the donor and the patient from knowing, the donor can perform desensitization processing on the physical examination report, such as deleting personal information such as name, identification number, contact information, address and the like in the physical examination report.

And step S826, after receiving the fourth donation broadcast message, the donation node public key is used for verifying the signature of the donation node private key, and under the condition that the signature passes, the donation node public key in the encrypted physical examination report is decrypted by using the private key of the donation node public key according to a predetermined algorithm to obtain the physical examination report of the donator.

And step S827, under the condition that the physical examination report is qualified, drafting an intelligent contract by the gifted node, and signing the intelligent contract by using a private key of the gifted node to obtain a third gifted broadcast message.

Wherein, the qualification of the physical examination report means that all indexes of the bone marrow donation accord with the bone marrow transplantation operation. The terms in the intelligent contract include, but are not limited to, the donor node blockchain identification, the recipient node blockchain identification, the donor bid amount, and the default funds. The default money is an amount of compensation to be paid to the patient for the default of the donation due to the non-physical reason of the donor, the amount of compensation may be 10 times the amount of the donation offer, or other amounts, and the embodiment does not limit the amount of compensation.

In this embodiment, if the bone marrow donation is over, the patient needs to pay the donation price amount to the donor, and if the bone marrow donation cannot be performed due to the donor, the donor needs to pay the default money to the patient.

It should be noted that default time is also stipulated in the intelligent contract, for example, after the patient enters a warehouse and begins to undergo chemotherapy for myeloablation, the bone marrow donor does not donate or violates for more than hours. And if the donation of the bone marrow donor is finished and a donation certification record is issued, and the success of the donation is not confirmed by the patient for more than time, automatically transferring the money to the bone marrow donor. Different thresholds are set for different situations to limit both donor and patient.

Step S828, after receiving the third donation broadcast message, the donation node verifies the signature of the private key of the donation node using the public key of the donation node, obtains the specific terms of the intelligent contract if the verification passes, and if the terms of the intelligent contract are agreed, performs secondary signature on the intelligent contract using its own private key to obtain a fifth donation broadcast message, and sends the fifth donation broadcast message to the blockchain network.

Step S829, the starting node automatically executes the corresponding transfer processing of the subsequent deposit and the default deposit according to the condition and the mechanism code of deposit processing in the intelligent contract.

Step S830, when the donation node completes the bone marrow donation, the donation node signs the donation bone marrow surgery record slip and the stem cell extraction record slip by using its own private key to obtain a sixth donation broadcast message, and sends the sixth donation broadcast message to the blockchain network, so that the originating node can perform subsequent payment and deposit refund operations according to the intelligent contract.
