Through the above technical features, the present embodiment has the following advantages:
The material management and control system based on the blockchain technology can record material information based on the blockchain, and the blockchain has the advantages of non-falsification and multiparty synchronization, so that the whole life cycle of the material information is recorded based on the blockchain, the possibility of forging data and falsifying the data can be avoided, and the donated material information is more conveniently maintained.
And the blockchain technology-based material management and control system freely and safely exchanges donation data, records donation data, updates donation data in a trust environment and records the whole life cycle of donation materials from a donation party, a middle party and a donation party.
The flow control system is described in detail below.
The donor terminal may register with the public chain before donating the supplies.
After entering the identity information of the donator, the donator terminal sends the identity information of the donator to a public chain, and the public chain calls an identity authentication mechanism to check the identity information of the donator, and after successful check, a digital certificate is issued to the donator terminal.
The intermediary terminal may register with the public chain before donating the supplies.
After the identity information of the intermediate party is input, the intermediate party terminal sends the identity information of the intermediate party to a public chain, and the public chain calls an identity authentication mechanism to check the identity information of the donation party, and after the verification is successful, a digital certificate is issued to the intermediate party terminal.
The donor may register with the public chain before sending the demand materials.
After entering the identity information of the donor, the terminal of the donor sends the identity information of the donor to a public chain, and the public chain calls an identity authentication mechanism to verify the identity information of the donor, and after verification is successful, a digital certificate is issued to the middle donor.
It will be appreciated that different authentication methods may be employed by the identity authentication mechanism for the donor, intermediary, or donor. The authentication modes of the intermediate party and the donor party are strict, so that the intermediate party and the donor party are ensured to be real and reliable.
The identity authentication mechanism is used for verifying the identity information of the donor terminal, the intermediate terminal and the donor terminal under the condition of the donor terminal, the intermediate terminal, the donor terminal and registering or logging in a public chain, and issuing digital certificates to the donor terminal, the intermediate terminal and the donor terminal after verification is passed.
The following describes a donation method based on a material management and control system, see fig. 2, comprising the steps of:
Step S201: and the donator terminal logs in the public chain through a digital certificate issued by the identity authentication mechanism, and issues donation material information to the public chain after successful login.
The donator terminal can log in the public chain through the digital certificate, and can issue donation material information to the public chain after successful login. Or alternatively
The donator terminal can log in the public chain through the digital certificate, and can check the lack of material information recorded by the public chain after successful login, and pertinently issue donation material information. In the case of targeted release of donation information, a donor terminal may designate one intermediate terminal.
Step S202: and the public chain verifies the digital certificate of the donor terminal, confirms successful login after verification is successful, receives the donation material information of the donor terminal, and sends the donation material information to the intermediate terminal.
And verifying the digital certificate of the donator terminal by the public chain, and after the verification is successful, explaining that the donator is a legal donator. The public chain receives the donation information of the donation party terminal, and sends the donation information to the middle party terminal under the condition that the donation party designates the middle party terminal so as to enable the middle party terminal to audit the donation information.
In the case where the donor does not designate an intermediary terminal, the donor material information may be sent to an intermediary terminal that is closer to the donor's geographic location. For example, if the donor is in a city of a province, the donation information may be sent to an intermediate terminal corresponding to the city of the province.
Step S203: the intermediate terminal logs in the public chain through a digital certificate issued by the identity authentication mechanism, verifies the legality of the donated material after truly receiving the donated material on line, and records the donated material information to the public chain after the verification is successful.
The intermediate terminal issues a login public chain through the identity authentication mechanism, and the intermediate terminal is verified to pass after the login is successful. And after the login is successful, receiving donation material information sent by the donation party terminal, checking the legality of the donation material (such as whether the checking quantity is complete, whether the checking material is perfect, whether the checking type is correct or not and the like) according to the legality rule of the donation material by the intermediate party terminal, and recording the donation material information to the public chain after the checking is successful.
The donation party terminal and the middle party terminal can negotiate what mode is adopted to transfer the real donation materials, if a logistics mechanism is adopted to transfer the real donation materials, the donation party terminal and the logistics party establish a logistics transaction, and the donation party is used as a sender and the middle party is used as a receiver in the logistics transaction.
The logistic transaction process can interface with the logistic system to track the logistic status of the real donated supplies in real time. After the intermediate side terminal receives the donated material, the logistics transaction can be confirmed in the public chain, so that the process of truly donating the material from the donation side to the receiving side is completed.
In the case where a logistics organization is not employed to transfer real donation materials, the donor terminal may be transported directly to the intermediate terminal site, in which case there may be no logistics transaction process.
Step S204: the intermediate terminal stores donation material information.
The intermediary terminal may save the donation material information to indicate that the intermediary terminal has the donation material.
Step S205: and the public chain receives donation material information recorded by the intermediate terminal, classifies the donation material information, and records the donation material information into corresponding public chain nodes in the public chain according to material categories.
The public chain receives the confirmation instruction of the intermediate terminal, and since donation materials can be of multiple types, donation material information can be classified, and the classified records are recorded in the corresponding public chain nodes.
Taking "mask" as an example, when there are "masks" in the donated material, the number of "masks" may be added to the common chain node corresponding to the "masks". It will be appreciated that there are many types of masks, such as medical masks, N95 masks, and children masks, and that the classification records may be classified according to finer classifications under the common chain nodes corresponding to the "masks".
Each batch of donated supplies will record the full life cycle of the donated supplies. Such as the donor and the date and number of donations, the intermediate and intermediate receiving dates and numbers, the logistics organization of the pathway, and the date and number of donations of the subsequent donated parties, etc.
Step S206: the terminal of the presented party logs in the public chain through the digital certificate issued by the identity authentication mechanism, and issues the demand material information to the public chain after the login is successful.
The terminal of the donor logs in the public chain through the digital certificate issued by the identity authentication mechanism, and after the login is successful, the terminal of the donor is described as a legal user. In the case of a lack of supplies by the donor, the demand supply information can be issued to the public chain.
Step S207: and the public chain verifies the digital certificate of the terminal of the donor, confirms login after verification is successful, classifies the required material information after receiving the required material information of the donor, and adds the required material information into corresponding public chain nodes in the public chain according to material categories.
And the public chain verifies the digital certificate of the terminal of the donor and determines the information of the required materials after the verification is successful. In general, there are a variety of demand material information, and the demand material information may be added to corresponding public chain nodes in a public chain according to material types.
Continuing taking "mask" as an example, in the public chain node corresponding to the mask, the number of masks donated by each donation party can be recorded, and the number of masks lacking by each donation party can also be recorded.
Step S208: and the public chain pushes the demand material information to at least one intermediate terminal.
The public link point in the public chain pushes the demand material information to at least one intermediate terminal based on the demand material information in the public link node.
The public chain nodes also record the quantity of materials corresponding to the terminals of all intermediate parties, for example, the quantity of masks existing in all intermediate parties can be comprehensively calculated in the public chain nodes corresponding to the 'masks'.
The public chain can push the demand material information to the intermediate terminal with the mask so that the intermediate terminal donates the material.
Step S209: and the intermediate side terminal receives the demand material information pushed by the public chain, and establishes donation transaction with the donated side terminal on the public chain after verifying the legality of the demand material information.
And the intermediate terminal receives the demand material information pushed by the public chain and verifies whether the demand material information is legal or not based on the standardization requirement of the demand material. After verifying the legitimacy of the demand material information, a donation transaction is established to the public chain at the terminal of the donor.
The middle side terminal and the donated side terminal can negotiate what mode is adopted to transfer the real donated materials, if a logistics mechanism is adopted to transfer the real donated materials, the middle side terminal and one logistics side terminal in a public chain establish logistics transportation, and the middle side is used as a sender and the donated side is used as a receiver in the logistics transportation.
The logistics transportation process can dock the logistics system so as to track the logistics condition of the real donated materials in real time. After the intermediate receives the donation, the donation transaction can be confirmed in the public chain, so that the process from the intermediate to the donated party of the real donation is completed.
Step S210: after the donation terminal receives donation materials truly on line, the state and transaction legitimacy of the intermediate terminal are checked, and a donation transaction completion instruction is sent to the public chain.
Step S211: public chains record the full life cycle of the donor terminal, the pathway intermediate terminal, the donor terminal.
According to the technical characteristics, the invention has the following beneficial effects:
The donation material information is shared in the public chain, so that the donation material information is recorded by each public chain link point in the public chain, and the mutual correlation between the public chain and the public chain is ensured by cryptography, so that the tampering difficulty and the tampering cost are very high.
The material management and control system based on the blockchain technology can record material information based on the blockchain, and the blockchain has the advantages of non-falsification and multiparty synchronization, so that the whole life cycle of the material information is recorded based on the blockchain, the possibility of forging data and falsifying the data can be avoided, and the donated material information is more conveniently maintained.
The blockchain is utilized to record donation material information, so that the material management and control system can freely and safely exchange donation data, record donation data and update donation data in a trusted environment, and record the full life cycle of donation materials from a donation party, an intermediate party, a route logistics party and a donated party.
And the donor terminal is also used for inquiring the life cycle of the donation material information from the public chain.
And the intermediate terminal is also used for inquiring the life cycle of the donation material information from the public chain.
The donor terminal is further configured to query the public chain for a life cycle of the donation material information.
The public chain can open an API interface so as to enable public terminals with specific authorities to inquire the full life cycle of donated materials, so that the donated materials are kept transparent, the problem of asymmetric information is solved, and the distribution efficiency is improved.
