Each module in the present embodiment is a logical module, and in practical applications, one logical unit may be one physical unit, may be a part of one physical unit, or 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, the following describes a method for establishing a bone marrow matching block chain based on a recipient node, a donor node, an operator node, and an originator node.

As shown in fig. 10, the method for bone marrow typing based on blockchain includes:

step S1001, the donation node accesses the block chain, and encrypts the personal information of the donator by using the public key of the operator node to obtain the first donation node encryption result.

The public key of the operator node is obtained by the donation node through inquiring the starting block, the public key of the operator node and the private key of the operator node both belong to the secret key of the operator node, and the signature of the private key of the operator node can be verified through the public key of the operator node.

In some embodiments, after the donor node accesses the blockchain, the starting block of the ledger of the blockchain is synchronized, and then the starting block is queried to obtain the public key and the identity of the operator node.

In order to save the electric quantity and the storage space of the terminal used by the donation node, the donation node only needs the first starting block of the account book of the synchronous block chain, and does not need all the account books of the synchronous block chain.

In some embodiments, the personal information of the donor includes, but is not limited to, the name, identification number, phone number, etc. of the donor. The public key of the operator node is used for encrypting the personal information of the donor, so that the safety of the personal information of the donor can be improved.

It should be noted that each donor corresponds to one donor node, so as to ensure the uniqueness of each donor.

Step S1002, the donation node performs hash calculation on the name and the identification card number of the donator according to a predetermined algorithm to obtain a hash value of the donation node.

The predetermined algorithm may be any algorithm suitable for hash calculation, which is not limited in this embodiment.

Because the identification card number has uniqueness, the hash value obtained according to the identification card number also has uniqueness. Therefore, the hash value of the donation node is used as the unique identifier of the donation node in the block chain, so that the repeatability of the donator can be avoided.

Step S1003, the donation node signs the donation node hash value, the donation node public key and the first donation node encryption result by using the private key of the donation node, obtains a first donation node broadcast message, and broadcasts the first donation node broadcast message in the block chain.

And the hash value of the donation node, the public key of the donation node and the encryption result of the first donation node are used as registration information of the donation node, and the registration information is broadcasted in the block chain so as to complete the registration of the donation node.

The private key of the donation node and the public key of the donation node are both the secret key of the donation node, and the signature of the private key of the donation node can be verified through the public key of the donation node.

When miners in the block chain only receive the broadcast message of the first donation node, the donation node is not registered, and after the fact that the miners receive the verification of the authenticity of the donator by the operator node, the registration of the donation node is completed according to the registration information.

In step S1004, the operator node verifies the registration information of the donor node, and generates a first operator node broadcast message and broadcasts the first operator node broadcast message in the blockchain if the verification passes.

After receiving the broadcast message of the first donation node, the operator node verifies the private key signature of the donation node by using the public key of the donation node, extracts the encrypted result of the first donation node under the condition that the verification is passed, decrypts the encrypted result of the first donation node by using the private key of the operator node according to a predetermined algorithm to obtain the personal information of the donator, and queries a database according to the mobile phone number in the personal information to verify the authenticity of the donator; under the condition of verifying that the information of the donor is real and effective, the operator node signs the registration information of the donor node by using a private key of the operator node to obtain a first operator node broadcast message, and broadcasts the first operator node broadcast message in a block chain.

The registration information of the donation node carried by the first operator node broadcast message is signed by the donation node twice by using a private key of the donation node and by using a private key of the operator node by using the operator node.

Step S1005, after receiving the broadcast message from the first operator node, the originator node/the miners verify their private key signatures using the public key of the donation node and the public key of the operator node, query the block chain account book if the two private key signatures are verified, and write the registration information of the donation node into the block chain account book if the donation node is determined to be unregistered.

The public key of the operator node can be obtained from the originating node, and the public key of the donor node is extracted from the received registration information of the donor node.

In this embodiment, the operator node verifies the donation node registration information, and can ensure the authenticity of the user registered by the donation node, so as to ensure the reliability of the information protection of the donator. Inquiring the blockchain account book can ensure that one donation node can be registered in the blockchain only once, thereby avoiding mass attacks of illegal users.

Step S1006, the donor node encrypts the contact information of the donor by using the public key of the originator node to obtain a second donor node encryption result.

It should be noted that the second donation node encryption result only carries the contact information of the donor, and does not include the name and the identification card information of the donor, so that mutual recognition between the donor and the recipient is avoided, bone marrow donation is performed under the condition that the two parties are not in face and in recognition, and subsequent unnecessary life disputes are avoided.

Step S1007, the donation node signs the donation node hash value, the donator gene hash value, and the second donation node encryption result by using its own private key, obtains a second donation node broadcast message, and broadcasts the second donation node broadcast message in the block chain.

The donor gene hash value is obtained by sequencing a plurality of gene point location information of the donors by the donor nodes according to a predetermined sequence and then performing hash calculation based on the sequenced gene point location information.

In this embodiment, the donor node may select the important gene point location information of ten donors to perform hash calculation, or select the important gene point location information of other numbers of donors to perform hash calculation, so as to obtain the donor gene hash value. The amount of donor gene locus information is based on meeting the bone marrow match.

In this embodiment, the gene site location information of the donor is not directly broadcast in the blockchain, but the hash value based on the gene site location information is broadcast in the blockchain, so that the privacy of the donor can be protected, and the biological crime research can be performed after lawless persons obtain the gene site location information.

Step S1008, after the originator node/the miners receive the second donation node broadcast message, the private key signature of the donation node in the second donation node broadcast message is verified by using the public key of the donation node, and after the verification is passed, the hash value of the donation node, the hash value of the donation gene, and the encryption result of the second donation node are written into the block chain account book.

It should be noted that steps S1001 to S1008 only exemplarily describe how one donor node completes registration in the blockchain, and writes the donor node hash value, the donor gene hash value, and the second donor node encryption result into the blockchain account, and other donor nodes may also register in the blockchain according to steps S1001 to S1008, and write the donor node hash value, the donor gene hash value, and the second donor node encryption result into the blockchain account, so that a large amount of encrypted genetic information and contact information of bone marrow donors are stored in the blockchain account.

In some embodiments, after the donor completes registration and uploads the gene site location information through the donor node, the donor may operate offline until receiving an online notification message.

Step S1009, the gifted node accesses the block chain, encrypts the personal information of the gifted person using the public key of the operator node, and obtains the first gifted node encryption result.

The personal information of the recipient includes, but is not limited to, the name, identification number, phone number, etc. of the recipient. The personal information of the recipient is encrypted by using the public key of the operator node, so that the security of the personal information of the recipient can be improved.

And step S1010, the gifted node performs hash calculation on the name and the identity card number of the gifted person according to a predetermined algorithm to obtain a hash value of the gifted node.

Wherein, the hash value of the donated node is used as the unique identifier of the donated node in the block chain.

In step S1011, the gifted node signs the hash value of the gifted node, the public key of the gifted node, and the encryption result of the first gifted node by using its own private key, obtains a broadcast message of the first gifted node, and broadcasts the broadcast message of the first gifted node in the block chain.

And the hash value of the donated node, the public key of the donated node and the encryption result of the first donated node are used as registration information of the donated node, and the registration information is broadcasted in the block chain so as to complete the registration of the donated node.

The private key of the given node and the public key of the given node are both the keys of the given node, and the signature of the private key of the given node can be verified through the public key of the given node.

When miners in the block chain only receive the broadcast message of the first donated node, the donated node is not registered, and after the miners receive the verification of the authenticity of the donator by the operator node, the registration of the donated node is completed according to the registration information.

In step S1012, the operator node verifies the registration information of the donor-recipient node, and in case the verification passes, generates a second operator node broadcast message, and broadcasts the second operator node broadcast message in the block chain.

After receiving the broadcast message of the first given node, the operator node verifies the private key signature of the given node by using the public key of the given node, extracts the encrypted result of the first given node under the condition that the verification is passed, decrypts the encrypted result of the first given node by using the private key of the operator node according to a predetermined algorithm to obtain the personal information of a given person, and queries a database according to the mobile phone number in the personal information to verify the authenticity of the given person; under the condition that the information of the donate is verified to be real and valid, the operator node signs the registration information of the donate node by using a private key of the operator node, obtains a second operator node broadcast message, and broadcasts the second operator node broadcast message in the block chain.

The registration information of the given node carried by the broadcast message of the second operator node is signed twice by the given node by using the private key of the given node and by using the private key of the operator node by using the operator node.

Step S1013, after the originator node/the miners receive the broadcast message of the second operator node, the public key of the donated node and the public key of the operator node are used for verifying respective private key signatures, the block chain account book is inquired under the condition that the two private key signatures are verified, and the registration information of the donated node is written into the block chain account book under the condition that the donated node is confirmed to be unregistered.

The public key of the operator node can be obtained from the originating node, and the public key of the gifted node is extracted from the received registration information of the gifted node.

In this embodiment, the operator node verifies the gifted node registration information, and can ensure the authenticity of the gifted node registered user, thereby ensuring that the gifted node information is reliable. Inquiring the blockchain ledger can ensure that a given node can only be registered once in the blockchain, thereby avoiding illegal backselling of bone marrow.

And step S1014, synchronizing all block chain accounts by the donated nodes, sequencing the gene point location information of the donates according to a predetermined sequence, and performing Hash calculation based on the sequenced gene point location information to obtain the gene Hash value of the donates.

In this embodiment, the donor node may select the important gene point location information of ten donors to perform hash calculation, or select the important gene point location information of other numbers of donors to perform hash calculation, so as to obtain the donor gene hash value. The number of gene locus location information of the recipient is based on the requirement of bone marrow matching.

Step S1015, the recipient node searches for the block chain account book based on the recipient gene hash value, and if the corresponding donor gene hash value is obtained, signs the donor node hash value, the donor gene hash value, and the second donor node encryption result using its own private key, obtains a second recipient node broadcast message, and broadcasts the second recipient node broadcast message in the block chain.

Wherein, in order to avoid a plurality of receivers to rob the marrow resource, more avoid unfairly flat phenomenon, the node given a gift can be sent the second node broadcast message given a gift to the timestamp server, give the second node broadcast message given a gift by the timestamp server and increase the timestamp, namely, the second node broadcast message given a gift carries the timestamp, the timestamp can distinguish the precedence order of the second node broadcast message given a gift that the node was given a gift issued, the different receivers who need the same type of allotment have been avoided to the question of fairness, thereby avoid unnecessary dispute.

Step S1016, after the originating node receives the second donated node broadcast message, the public key of the donated node is queried in the block chain account book through the donated node hash value, the private key of the donated node in the second donated node broadcast message is verified by using the public key of the donated node, and under the condition that the verification is passed, the donated node hash value, the donator gene hash value, and the second donated node encryption result are obtained. And the originating node decrypts the encrypted result of the second donation node by using the private key of the originating node according to a predetermined algorithm to obtain the contact information of the donator.

The originating node notifies the donor to go online. The present embodiment may notify the donor to go online through a telephone or other means, and the present application does not limit the manner of notifying the donor to go online. After uploading the gene information and the contact information of the donor to the blockchain, the donor may not find a donor capable of being matched with the donor for several years or even for life, and if the donor is always online, unnecessary consumption of electric quantity and flow is easily caused.

Step S1017, the donor node sends a third donor node broadcast message.

And if the donor does not agree with the bone marrow donation, the third donation node broadcast message is not sent.

In some embodiments, the third donor node broadcasts a message including information agreeing to the bone marrow donation and a donation price. And, the donation node signs the information agreeing to the bone marrow donation and the donation offer with its own private key and then obtains a third donation node broadcast message.

Step S1018, after the donated node receives the third donation node broadcast message, the public key of the donation node is used to verify the private key signature of the donation node, and the third donated node broadcast message is broadcast in the block chain under the condition that the verification is passed and the donation offer of the donator is agreed by the donator.

And under the condition that the verification of the donation node is passed and the donation of the donator is agreed by the donator, the donation node signs the thank you information by using the private key of the donation node, and a third donation node broadcast message is obtained. Meanwhile, the gifted node can also send the cost required by the physical examination to the gifted node.

Step S1019, the donation node encrypts the health examination report according to a predetermined algorithm by using the public key of the donation node, signs the encrypted health examination report by using the private key of the donation node to obtain a fourth donation node broadcast message, and broadcasts the fourth donation node broadcast message in the block chain.

For example, to avoid revealing the personal information of the donors, before encrypting the physical examination report, the physical examination report is decrypted, namely the personal information of the names, identification numbers, mobile phone numbers, addresses and the like of the donors is deleted.

And step S1020, after the donated node receives the fourth donation node broadcast message, verifying the private key signature of the donation node in the fourth donation node broadcast message by using the public key of the donation node, and decrypting the encrypted physical examination report by using the private key of the donated node according to a predetermined algorithm under the condition that the verification is passed, so as to obtain the physical examination report of the donator.

And step S1021, under the condition that the physical condition of the donor is confirmed to accord with the bone marrow transplantation operation according to the physical examination report of the donor, making an intelligent contract, and signing the intelligent contract by using a private key of the intelligent contract to obtain a fourth donated node broadcast message.

The recipient can analyze the physical examination report of the donor through a professional, and make an intelligent contract if the physical condition of the donor is confirmed to be in accordance with the bone marrow transplantation operation. Terms in the intelligent contract include, but are not limited to, the donor node hash value, the recipient node hash value, the donor offer amount, and the default amount. The default money is the reimbursement money to be paid to the recipient after the donation default is caused by the non-physical reason of the donor, the reimbursement amount may be 10 times the donation price amount, or other fixed amount, and the reimbursement amount is not limited in this embodiment.

In this embodiment, if the bone marrow donation is over, the patient needs to pay the donation price amount to the donor while returning the deposit to the donor. If a bone marrow donation cannot be made due to the donor, the donor needs to pay a default fee to the recipient.

It should be noted that default time is also agreed in the intelligent contract, for example, after the patient enters a warehouse and begins to undergo large chemotherapy for marrow clearance, the bone marrow donor does not donate or default 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 S1022, the donation node performs secondary signature on the intelligent contract by using its own private key, obtains a fifth donation node broadcast message, and broadcasts the fifth donation node broadcast message in the block chain.

When the donor agrees with each term in the intelligent contract, the donor node signs the intelligent contract for the second time by using the private key of the donor node, namely the fifth donor node broadcast message carries the private key signature of the donated node and the private key signature of the donor node.

And S1023, automatically executing corresponding transfer processing of subsequent deposit and default deposit by the originating node according to a mechanism code of deposit processing in the intelligent contract and a preset condition.

Wherein, the starting node is the leading person and the founding person of the marrow matching block chain network. The preset condition is a condition for executing an intelligent contract term, such as the default term described above.

Step S1024, under the condition that the bone marrow donation is completed, the donation node signs the donation bone marrow operation record sheet and the stem cell extraction record sheet by using a private key of the donation node to obtain a sixth donation broadcast message, and sends the sixth donation broadcast message to the block chain network, so that the originating node can conveniently execute subsequent payment and deposit refund operations according to an intelligent contract.
