Description
Technical Field

Background
Donation is a public welfare which volunteers to dedicate things owned by oneself to the society in order to help others live. In addition, in order to guarantee the rights and interests of the donated objects, the donated objects can receive help preferentially and without payment by means of previous donation information or donation information of relatives of the donated objects when the donated objects need help. For example, when a donor needs blood, the donor can give priority to blood consumption for compensation by using the previous blood donation information or the blood donation information of the relative.
At present, in order to record the donation information of a donated object, after each donation of the donated object, the association receiving the donation may issue a donation certificate recorded with the donation information to the donated object, so that the donated object may receive help preferentially by means of the donation certificate when the donated object needs help in the future. For example, after each donation by a donor, the blood-donating association issues to the donor a blood-donating certificate that records the number of donations and the amount of donated blood, so that the donor can prioritize the use of blood for compensation when the donor needs blood at a later date.
However, because the donation certificate only donates the object and needs to be carried at any time, the current storage method for donation information may result in low query efficiency of donation information, a single query method, and low transparency of donation information.

Detailed Description
in order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
fig. 1 is a schematic diagram of an implementation environment related to a distributed storage method for donation information according to an embodiment of the present invention. As shown in FIG. 1, the implementation environment may include: a pre-established blockchain network 10, where the blockchain network 10 may include a plurality of nodes 101 (only 4 nodes are shown in fig. 1), each node 101 may be a computer device, and each node 101 may receive input information during normal operation and maintain shared data within the blockchain network 10 based on the received input information. For example, referring to fig. 1, the computer device may be a server, or may also be a terminal device such as a desktop computer or a smart phone.
Also, referring to fig. 1, in order to ensure the information intercommunication of the blockchain network 10, a communication connection may be established between the nodes 101, and information transmission may be performed between the nodes 101 through the communication connection. That is, when any node 101 receives data, the data can be broadcast to the entire blockchain network 10, so that other nodes 101 in the blockchain network 10 can receive and store the data, i.e., all nodes 101 included in the blockchain network 10 can store the data. Optionally, each node 101 may further have a node identifier corresponding thereto, and may store node identifiers of other nodes in the blockchain network 10 except the node, so that each node 101 may reliably broadcast the received data to the other nodes through the communication connection according to the node identifiers of the other nodes.
For example, referring to table 1, a node identification list maintained in each node 101 is shown, which may include: node name and node identification. The node identifier may be an Internet Protocol (IP) address and any other information that can be used to identify the node, and only the IP address is used as an example in table 1. For example, referring to table 1, the node name is node 1, and the node identifier corresponding to the node 1 is: 117.114.151.174.
TABLE 1
| Node name | node identification |
| Node 1 | 117.114.151.174 |
| Node 2 | 117.116.189.145 |
| … | … |
| node N | 119.123.789.258 |
in addition, in order to ensure the consistency of the data stored by each node 101, each node 101 may also maintain the entire blockchain network 10 based on a set of consensus mechanisms. That is, the nodes 101 may perform data correction for multiple times through a pre-configured consensus algorithm, and continuously broadcast the data that is corrected for the last time to the whole network until the data stored by the nodes 101 are consistent, that is, until the nodes 101 achieve consensus. The principle of the consensus algorithm comprises the following steps: the node receiving the data compares the received data with the data stored in the node, and the data with the accuracy rate larger than the accuracy rate threshold value in the plurality of data determined after comparison is broadcasted to the whole network again; then, the node receiving the corrected data continues to repeatedly perform the comparison operation, i.e., perform network diffusion iteration until the whole network is agreed.
For example, in the embodiment of the present invention, a node that receives a donation record for the first time may broadcast the donation record to the entire network, and any node that receives the donation record sent by the node may compare the received donation record with a donation record that is pre-stored by itself (i.e., make a consensus on the donation record), and broadcast the more correct donation record after comparison to the entire network again. And any node receiving the corrected donation records continuously compares the corrected donation records with donation records stored in advance, broadcasts the more correct donation records to the whole network again after comparison, and continuously executes repeatedly until the donation records stored by all nodes in the network are consistent.
it should be noted that, in the embodiment of the present invention, the blockchain network 10 may be a decentralized network system, i.e., the donation records may be managed by the blockchain network 10 in a decentralized technology. Wherein, decentralization means: there is no concept of a central node in the blockchain network 10, the positions of the nodes 101 in the blockchain network 10 are equal, each node 101 may store the same blockchain, each blockchain includes a plurality of blocks, each block stores different data, and the data stored in all the blocks on the blockchain constitute all the shared data of the blockchain network.
In addition, since the distributed storage method for the donation information provided by the embodiment of the present invention needs to receive the donation record of the donation object, needs to query the donation information of the donation object, and may even need to receive the parent information of the donation object, the mechanism for collecting the donation of the donation object, the mechanism for querying the donation information of the donation object, and the mechanism for collecting the parent information of the donation object all need to be added to the blockchain network 10. Of course, the donor subject may also join the blockchain network 10 by himself through his terminal.
For example, assuming the donation is blood, the donation information may be blood donation information. Referring to fig. 2, the institution collecting the donor's blood (e.g., a blood collection station), the institution inquiring about the donor's blood donation information (e.g., a hospital), and the institution collecting the donor's relatives information (e.g., a public office and a local office) each need to join the blockchain network 10, i.e., the computer devices of the institution collecting the donor's blood, the structure inquiring about the donor's blood donation information, and the institution collecting the donor's relatives information need to become nodes in the blockchain network 10. Of course, the donor himself may also join the blockchain network 10 via his terminal.
The donation information is stored and managed through the block chain technology, and compared with the related technology that donation information is stored and managed through a donation certificate, the method can directly inquire on line when a donation object urgently needs help, so that the inquiry is more convenient, and the efficiency is higher. And because the transparency of the blockchain network is higher, the information transparency of the donated information is higher.
fig. 3 is a flowchart of a donation information distributed storage method according to an embodiment of the present invention, which may be applied to any node included in the blockchain network shown in fig. 1. As shown in fig. 3, the method may include:
Step 301, receiving a donation record for a donated object.
wherein the donation record may include a user identification and donation information for the donated object. Alternatively, the user identifier may be information (such as an identity document identifier or a genetic identifier) for uniquely indicating the user identity. The donation information may include at least one of information related to a user donation (e.g., a donation time of a donated object, a donation location, a donation or a donation amount of a donation).
In the embodiment of the present invention, when a donation object donates, a user identifier of the donation object may be notified to a user who collects the donation object, and then the user who collects the donation object may upload the received donation information of the donation object and the user identifier provided by the donation object to any node of a pre-established blockchain network through a terminal. That is, any node may receive a donation record for a donated object uploaded by a user.
Step 302, broadcast the donation records to the blockchain network over the entire network.
In the embodiment of the present invention, after receiving the donation record, the node may broadcast the received donation record to the entire network of the blockchain network, that is, the node of the received donation record may transmit the donation record to other nodes through a communication connection established with other nodes, so that each node may store the donation record.
Optionally, in order to ensure consistency of information stored by each node, each node that receives the donation records may further perform consensus processing on the donation records through a consensus algorithm and then broadcast the donation records to the whole network again, and continuously execute the consensus processing until the donation records stored by each node are all consistent.
step 303, receiving a donation information query request carrying the user identifier to be queried.
In the embodiment of the present invention, if the donation information of a certain user needs to be queried, the user querying the donation information may input the user identifier of the user to be queried to the node through the terminal, and accordingly, the node may receive the donation information query request carrying the user identifier to be queried.
and step 304, inquiring the donation information corresponding to the user identifier to be inquired according to the donation information inquiry request.
when any node receives a donation information query request carrying a user identifier to be queried, the node can determine the identity of a donation object according to the user identifier, reliably search the donation information of the donation object according to the determined identity of the donation object, and inform a querier of the queried donation information.
In summary, the embodiment of the present invention provides a method for distributed storage of donation information. Any node of the pre-established blockchain network can receive the donation records of the donated objects and broadcast the donation records to the whole blockchain network, so that all nodes included in the blockchain network can store the same donation records. And the node can also receive a donation information query request carrying the user identifier to be queried and automatically query donation information corresponding to the user identifier to be queried according to the request. The donation information is stored and managed through the block chain network technology, and compared with the method that donation information is stored and managed through a donation certificate in the related technology, the donation information of a donor can be directly inquired on line through the method, so that the donation information inquiry efficiency is higher, and the donation information transparency is higher. And when the user identification comprises multiple types, the query method can be richer.
Fig. 4 is a flowchart of another donation information distributed storage method according to an embodiment of the present invention, which may be applied to any node included in the blockchain network shown in fig. 1. As shown in fig. 4, the method may include:
step 401, a donation record for a donated object is received.
In the embodiment of the present invention, in order to manage the donation records by using the blockchain technique, the blockchain network 10 shown in fig. 1 needs to be established in advance, and the blockchain network 10 needs to include nodes belonging to the entity receiving the donation records, that is, the entity receiving the donation records needs to join the blockchain network 10. The user receiving the donation record of the donation object can upload the donation record of the donation object to the corresponding node through the terminal, namely, the node can receive the donation record of the donation object uploaded by the user.
Optionally, the donation record may include the user identifier and the donation information of the donation object, and correspondingly, the user who collects the donation may upload the user identifier provided by the donation object and the received donation information of the donation object to the node together, and the node that receives the donation record may store the user identifier and the donation information of the donation object in a one-to-one correspondence manner. For example, in a blood donation application scenario, referring to fig. 2, a blood collection facility (e.g., a blood collection station) that collects blood from a donor needs to join the blockchain network 10. The blood-collecting doctor who collects the blood of the blood donor can upload the user identification provided by the blood donor and the collected blood-donation information of the blood donor to the node through the terminal, namely the node can receive the blood-donation record of the blood donor uploaded by the blood-collecting doctor, and the node can correspondingly store the user identification of the blood donor and the blood-donation information one by one.
Wherein, the user identifier of the donated object can be information for uniquely indicating the identity of the donated object. For example, the user identification of the donated object may include: the identification information of the donated subject may be an identification number of the donor, and the genetic identification may be genetic information (also referred to as DNA information) stored in DeoxyriboNucleic Acid (DNA). By receiving the user identifier, the subsequent reliable inquiry of the donation information of different donation objects according to the user identifier can be facilitated. The donation information of the donated object may be information related to user donation, for example, the donation information of the donated object may include: at least one of a time of donation, a location of donation, a donation, and a donation amount of donation to the subject. For example, for a donor, the donation information of the donor may be blood donation information related to the blood donation of the donor, and the blood donation information of the donor may include: at least one of a blood donation time, a blood donation site, and a blood donation amount.
It should be noted that, for the same node, it may receive the donation information of different donated objects, so for the convenience of subsequent query, the node may also set a number for uniquely indicating the donated object for the different donated objects in advance.
For example, taking a blood donation scenario as an example, assuming that a number a is set for a donation object (i.e., a donor) by a certain node, fig. 5 shows a blood donation record of donor a received by the node. As can be seen with reference to fig. 5, the blood-donation record for donor a received by the node includes the donor's user identification including the donor's identification number and DNA, and the blood-donation information. The blood donation information includes a blood donation amount, a blood donation time, and a blood donation site. Optionally, the blood-donation record may also include other donor-related information. For example, the blood donation record may also include the blood type, name, cell phone number, address, and number of blood donations of the donor. For example, referring to fig. 5, the node shown also receives the blood type of donor a.
Step 402, broadcast the donation records to the blockchain network over the entire network.
In the embodiment of the present invention, in order to facilitate that each node of the entire blockchain network can store the donation record, the node receiving the donation record may broadcast the donation record to the entire network, that is, the node may send the donation record to each other node through a communication connection established with another node.
alternatively, since a donor may make multiple donations at different time points (e.g., a donor may make multiple blood donations at different time points), for the convenience of distinguishing and recording, a time stamp may be configured for each donation information in advance, and the time stamp configured for each donation information may be different. Correspondingly, any node can generate a target block according to the received donation information and the corresponding timestamp information, and broadcast the target block and the user identifier to the whole network. In addition, in order to ensure the consistency of the data stored in each node, as described above, any node that receives the target block and the user identifier may perform consensus processing on the received information, store the verified information, and broadcast the verified information to the entire block chain network again. Any node after receiving the check can perform consensus processing on the received target block again, broadcast to the whole network again, and iterate continuously until the information stored by each node of the whole block chain network is completely the same.
By way of example, taking a blood-donation scenario as an example, fig. 6 is a schematic diagram of another received blood-donation record of a blood donor according to an embodiment of the present invention, and as shown in fig. 6, the blood-donor a received by the node includes a plurality of blood-donation information, and each blood-donation information corresponds to one time stamp information. For example, blood-donation information 1 corresponds to timestamp 1, blood-donation information 2 corresponds to timestamp 2, blood-donation information 3 corresponds to timestamp 3, and so on. In connection with fig. 5, each blood donation information may include information such as a blood donation time, a blood donation site, and a blood donation amount, and fig. 6 is not shown.
And step 403, receiving the relative information of the donated objects sent by the personnel list statistics department.
In the embodiment of the present invention, the roster statistic department may include a civil administration (i.e., civil bureau) or a public security department (i.e., public security administration). Accordingly, the blockchain network needs to include nodes belonging to the roster, i.e., the roster receiving the information of the relatives of the donated objects needs to join the blockchain network. The personnel list statistical department can upload the relative information of the donated objects to the nodes through the terminal, namely, any node can receive the relative information of the donated objects sent by the personnel list statistical department.
Optionally, the staff list statistics department may periodically upload the information of the relatives of the donated objects, or the node may periodically obtain the information of the relatives of the donated objects from the staff list statistics department. In the embodiment of the invention, the personnel list statistical department is a higher authority organization such as a civil administration department or a public security department, so that the real-time performance and the reliability of the acquired relative information can be ensured. Certainly, the node can also receive the relative information uploaded by the donation object, namely, the donation object can also upload the relative information to the node through the terminal of the donation object.
By way of example, taking a blood donation scenario as an example, fig. 7 is a schematic diagram of the relative information received by a node according to an embodiment of the present invention. As shown in fig. 7, the node receiving the relative information of donor a includes: spouse, parent and child of donor a. Optionally, this step 403 may be executed synchronously with step 401, that is, the node may receive the blood-donation record and the relative information of the blood donor at the same time, and accordingly, may perform the consensus processing on the blood-donation record and the relative information at the same time, which saves processing resources.
Step 404, the information of the relative of the donated object is matched with the user identifier of the donated object.
In the embodiment of the invention, after receiving the relative information of the donated object, the node can match and correspondingly store the relative information and the user identifier of the donated object, thereby facilitating subsequent query.
for example, taking a blood donation scenario as an example, refer to fig. 8, which shows a schematic diagram of matching results of donor a and its relative information. As can be seen from fig. 8, for each relative, the node a also receives the blood donation record of the relative, and the recording method may refer to step 401 and step 402, which is not described again.
step 405, broadcasting the matching result to the whole block chain network.
In the same step 402, the node may notify other nodes of the matching result between the relative information of the donated object and the user identifier of the donated object in a network-wide broadcast manner, so that each node stores the relative information of the donated object. Similarly, in order to ensure the consistency of the data stored in each node, as described above, any node that receives the matching result may further perform consensus processing on the matching result, store the verified matching result, and broadcast the verified matching result to the entire blockchain network again. Any node after receiving the verification can perform consensus processing on the received matching result again, broadcast to the whole network again, and iterate continuously until the matching results stored by all nodes of the whole block chain network are completely the same. For the specific consensus process, reference is made to the above description, which is not repeated herein.
Step 406, receiving a donation information query request carrying the user identifier to be queried.
In the embodiment of the present invention, if the donation information of a certain user needs to be queried, the querier may input the user identifier of the user to be queried to the node through the terminal, and accordingly, the node may receive the donation information query request carrying the user identifier to be queried.
For example, taking a blood donation scenario as an example, assuming that the user identifier is an identity document identifier and the identity document identifier is an identity card number, when an inquirer uploads the identity card number of a blood donor to the node through a terminal, the node may receive a blood donation information inquiry request carrying the identity card number of the blood donor to be inquired.
step 407, inquiring the donation information corresponding to the user identifier to be inquired and the donation information of the relative of the donation object according to the donation information inquiry request carrying the user identifier to be inquired.
When a node receives a donation information query request carrying a user identifier to be queried, the node can determine the identity of a donation object according to the user identifier, reliably search donation information of the donation object according to the determined donation object identity, and inform a query result to a querier. Of course, for the relatives of the donated objects, the donation information may also be recorded by referring to the above steps 401 and 402, and correspondingly, the node may also query the donation information of the relatives of the donated objects according to the donation information query request.
It should be noted that, in the embodiment of the present invention, the user identifier may include an identity document identifier and a gene identifier, and correspondingly, the node may also query the donation information of the donated object according to the donation information query request carrying the gene identifier, and the query method is relatively rich. Moreover, under the condition that the gene identification or the identity document identification cannot be verified, verification is carried out through another verification mode, and the reliability is higher.
by way of example, reference is made to fig. 8, which shows the final stored blood-donation records for donor a, the relative information, and the corresponding blood-donation records for each relative. The storage contents and storage modes of the relative blood donation records and the blood donation record of the donor A are the same. Such as a spouse for donor a, whose blood-donation record includes a user identification of the spouse including the spouse's identification number and DNA, and blood-donation information including a plurality of blood-donation information, and timestamps corresponding to the plurality of blood-donation information.
it should be noted that, when receiving the donation information query request, the node may also verify the identity of the querier to determine whether the querier has the right to query the donation information of the donation object.
It should be further noted that, in order to facilitate that when a certain donation object needs help, a donation of a suitable donation object can be quickly selected, in the embodiment of the present invention, when the node receives a donation record of the donation object, the node may further perform classification processing on the donation of the donation object according to the target attribute, that is, the donations of different donation objects are classified and stored according to the target attribute.
for example, taking a blood donation scenario as an example, in order to facilitate a donor to quickly select appropriate blood for the donor when blood is needed urgently, when a node receives a blood donation record of the donor, the blood of different donors can be stored according to the health degree classification of the blood, i.e. the target attribute may be the health degree of a donation (i.e. blood). Optionally, for unhealthy blood, different types of diseases can be classified and stored for further convenient selection.
Fig. 9 is a flowchart of another method for distributed storage of donation information according to an embodiment of the present invention. As shown in fig. 9, the method may include:
Step 901, receiving the qualified status of the donation from the donation object.
Optionally, the user (e.g., a blood collection physician) receiving the donation may also perform qualification testing on the donation (e.g., blood) received from the subject (e.g., a blood donor), and upload the testing result to the node through the terminal. I.e., the node may receive eligibility status for the donation object donations uploaded by the user. Of course, the node may also directly detect the eligibility status of the donation when it receives the donation from the donated subject.
Step 902, broadcast the eligibility status of the donation to the blockchain network.
as in step 402, the node may inform other nodes of the eligibility status of the donation (e.g., the blood eligibility status of the donor) via a network-wide broadcast, so that each node stores the eligibility status of the donation. Similarly, in order to ensure the consistency of the data stored by each node, as described above, any node that receives the eligibility status of the donation may further perform consensus processing on the eligibility status of the donation, store the eligibility status of the verified donation, and broadcast the eligibility status of the verified donation to the entire blockchain network again. Any node after receiving the verification can perform consensus processing on the received information again, broadcast the information to the whole network again, and iterate continuously until matching results stored by all nodes of the whole block chain network are completely the same. For the specific consensus process, reference is made to the above description, which is not repeated herein.
step 903, when receiving a donation qualification status query request carrying the user identifier to be queried, querying the donation qualification status corresponding to the user identifier to be queried, and displaying a query result.
Like steps 406 and 407, when the inquirer needs to inquire the donation qualification status (e.g. blood qualification status) of the donated object, the inquirer (e.g. the donor himself) can input the user identifier thereof to the node through the terminal, and correspondingly, the node can receive the inquiry request of the donation qualification status carrying the user identifier to be inquired. And the node can quickly inquire the qualified condition of the donation according to the qualified condition inquiry request of the donation and display the inquiry result so that an inquirer can know the inquiry result. By the method, the risk of privacy disclosure of the patient caused by a manual informing mode of the patient can be avoided. Step 901 can be executed synchronously with step 401, and correspondingly, step 902 can be executed synchronously with step 402.
it should be noted that the donation information distributed storage method may be applied not only to the above-mentioned blood donation scenario, but also to other donation application scenarios. In addition, the order of the steps of the donation information distributed storage method provided by the embodiment of the present invention may be appropriately adjusted, such as step 403 may be executed synchronously with step 401, or executed before step 401. Any method that can be easily conceived by those skilled in the art within the technical scope of the present disclosure is covered by the present disclosure, and thus, the detailed description thereof is omitted.
In summary, the embodiment of the present invention provides a method for distributed storage of donation information. Any node of the pre-established blockchain network can receive the donation records of the donated objects and broadcast the donation records to the whole blockchain network, so that all nodes included in the blockchain network can store the same donation records. And the node can also receive a donation information query request carrying the user identifier to be queried and automatically query donation information corresponding to the user identifier to be queried according to the request. The donation information is stored and managed through the block chain network technology, and compared with the method that donation information is stored and managed through a donation certificate in the related technology, the donation information of a donor can be directly inquired on line through the method, so that the donation information inquiry efficiency is higher, and the donation information transparency is higher. And when the user identification comprises multiple types, the query method can be richer.
