Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a blockchain-based certificate management method, it is noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than here.
In this embodiment, as shown in fig. 1, an optional certificate management system is used as an execution subject to execute the above certificate management method based on the blockchain, where the certificate management system at least includes a certificate query module, a certificate display module, and a digital collection issuing system, and may further include a certificate making module, where the digital collection issuing system may include a blockchain module and a digital collection technology module. Alternatively, the certificate management system may be built into the platform associated with a charity.
Fig. 2 is a schematic diagram of an alternative certificate management method according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step S201, determining authority information of the target object, and determining the first target module according to the authority information.
In step S201, optionally, the certificate management system may determine the authority information of the target object, and determine the authority of the target object to acquire the certificate based on the authority information of the target object, so as to determine the first target module for responding to the relevant instruction of the target object according to the aforementioned authority. The target object may be an owner of the digital donation certificate to be queried, or may be a related authority or financial institution that needs to use the digital donation certificate, for example, the related authority may provide a tax deduction discount certificate or handle related services for the owner of the digital donation certificate according to the digital donation certificate, the related financial institution may handle related services for the owner of the digital donation certificate according to the digital donation certificate, and the like, and the first target module may be the certificate querying module or the certificate displaying module.
Step S202, a certificate inquiry instruction of the target object is responded through the first target module.
In step S202, the certificate management system may respond to the certificate query instruction of the target object through the determined first target module, so as to execute an operation of querying the certificate for the target object based on the certificate query instruction through the first target module. The certificate inquiry command at least includes inquiry information, where the inquiry information may be information such as a donor identity, a certificate hash value, and a certificate number corresponding to the digital donation certificate to be inquired, and the inquiry information may also be other information capable of characterizing the characteristics of the digital donation certificate to be inquired.
It should be noted that, by responding to the instructions of the target objects with different rights based on different modules, the digital donation certificate to be queried by the target object is fed back based on different modes, so that the phenomenon that an object with low credibility easily forges a directly acquired target digital donation certificate or an object with high credibility difficultly retains the target digital donation certificate in a picture form due to the fact that the target digital donation certificate is fed back to different target objects based on the same mode is avoided.
Step S203, determining a target digital donation certificate to be queried by the certificate query instruction from a second target module, where the second target module is used to store the target digital donation certificate.
In step S203, the first target module may directly determine the target digital donation certificate to be queried by the certificate query command from the second target module, and the first target module may also send a control command to other modules to control the other modules to determine the target digital donation certificate to be queried by the certificate query command from the second target module, and acquire the target digital donation certificate from the other modules, where the other modules are modules in the certificate donation system except the first target module, and the second target module may be a digital collection technology module.
Optionally, in the process of determining the target digital donation certificate to be queried by the certificate query instruction from the second target module, the first target module or another target module may match the information content of the query information with at least one digital donation certificate stored in the second target module, so as to determine the digital donation certificate consistent with the information content as the target digital donation certificate.
It should be noted that, the target digital donation certificate is stored in the second target module, so that the related users or organizations can conveniently inquire, browse and display on line through internet devices such as mobile phones and computers, the trouble that the paper certificate is inconvenient to carry is solved, and meanwhile, the problem that the donation certificate in the paper form is easy to forge is also avoided.
Step S204, verifying authenticity of the target digital donation certificate based on the information stored in the block chain, and feeding back the target digital donation certificate to the target object in a target mode through the first target module under the condition that the target digital donation certificate is determined to be authentic, wherein the block chain is at least used for storing a hash value corresponding to the digital donation certificate, and the first target module corresponds to the target mode.
In step S204, after the first target module obtains the target digital donation certificate, the first target module may first calculate a hash value of the obtained target digital donation certificate, and then search for a hash value corresponding to the query information in the certificate query instruction from a blockchain (that is, the blockchain module), and then the first target module may compare the calculated hash value with the found hash value, so that when the two hash values are the same, it is determined that the target digital donation certificate is authentic, otherwise, when the two hash values are different, it is determined that the target digital donation certificate is abnormal, thereby implementing the authenticity verification on the target digital donation certificate. Optionally, because of different actual application situations, the query information in the certificate query instruction may include a hash value of the certificate to be queried by the target object, and therefore, the first target module may also directly compare the hash value obtained from the query information with the hash value found from the blockchain, so as to verify the authenticity of the target digital donation certificate. In addition, the blockchain may also store certificate information corresponding to at least one digital donation certificate, and directly compare the certificate information with the target digital donation certificate to verify authenticity of the target digital donation certificate, where the certificate information at least includes donation information and may also include a certificate format of the digital donation certificate.
Further, after the first target module determines that the target digital donation is true, the first target module may feed back the target digital donation certificate to the target object based on a target mode, where the target mode may be directly sending the target digital donation certificate to the target object, may also be displaying the target digital donation certificate to the target object, and may also be sending the encrypted target digital donation certificate to the target object, so that the target object may obtain the target digital donation certificate after decrypting the target digital donation certificate. It should be emphasized that the first target module may also control other modules to perform authenticity verification on the target digital donation certificate after controlling other modules to acquire the target digital donation certificate, and acquire the authentic target digital donation certificate from other modules under the condition that the authenticity verification passes, so as to feed back to the target object based on a target manner.
It should be noted that, because the blockchain can effectively ensure that the stored information of the blockchain cannot be tampered, counterfeited, repudiated and traceable under the support of the transparent sharing and tamper-proof capability of the blockchain, the validity of the verification result can be effectively ensured by storing the hash value of the digital donation certificate into the blockchain and verifying the authenticity of the target digital donation certificate in the second target module based on the stored hash value in the blockchain before feeding the target digital donation certificate queried by the target object back to the target object, thereby ensuring the authenticity of the target digital donation certificate sent to the target object.
Based on the schemes defined in steps S201 to S204, it can be known that, in the embodiment of the present invention, in a manner that the authenticity of the certificate to be queried by the target object is verified based on the information stored in the block chain, and the certificate is fed back to the target object after the verification is successful, by determining the authority information of the target object and determining the first target module according to the authority information, then responding to the certificate query instruction of the target object through the first target module, and then determining the target digital donation certificate to be queried by the certificate query instruction from the second target module, the authenticity of the target digital donation certificate is verified based on the information stored in the block chain, and the target digital donation certificate is fed back to the target object in a target manner through the first target module under the condition that the target digital donation certificate is determined to be authentic. The second target module is used for storing a target digital donation certificate, the block chain is at least used for storing a hash value corresponding to the digital donation certificate, and the first target module corresponds to the target mode.
It is easy to notice that, in the above process, since the blockchain can effectively ensure that the stored information can not be tampered, forged, repudiated and marked in the whole process, the hash value of the digital donation certificate is stored in the blockchain, and before the target digital donation certificate inquired by the target object is fed back to the target object, the authenticity of the target digital donation certificate in the second target module is verified based on the stored hash value in the blockchain, so that the validity of the verification result can be effectively ensured, the authenticity of the target digital donation certificate sent to the target object is ensured, and the problem that the paper donation certificate in the prior art is easy to forge is avoided. In addition, the digital donation certificate to be inquired by the target object is fed back in different modes based on different target object authorities, so that the phenomenon that the target digital donation certificate which is obtained directly by the object with low credibility is easy to forge or the target digital donation certificate which is obtained in a picture form is difficult to preserve by the object with high credibility caused by feeding back the target digital donation certificate to different target objects in the same mode is avoided, and the authenticity of the donation certificate is further ensured.
Therefore, the scheme provided by the application achieves the purposes of verifying the authenticity of the certificate to be inquired by the target object based on the information stored in the block chain and feeding the certificate back to the target object after the verification is successful, thereby realizing the technical effect of improving the authenticity of the donated certificate and further solving the technical problem of low authenticity of the certificate caused by the fact that the donated certificate made of paper is easy to forge in the prior art.
In an alternative embodiment, before determining the rights information of the target object, the certificate management system may obtain the donation information of the donation object to the target organization, then generate a digital donation certificate based on the donation information, and generate a hash value corresponding to the digital donation certificate, so as to store the hash value corresponding to the digital donation certificate and the donation information in the blockchain.
Alternatively, as shown in fig. 1, after the social lover or the related organization makes a charitable donation to a charitable organization (i.e., the aforementioned target organization), the certificate management system may respond to the donation information sending request of the charitable organization, and call an interface of the certificate making module based on the donation information sending request, so that the certificate making module obtains the donation information that the donation object sent by the charitable organization makes a donation to the charitable organization. Furthermore, the certificate making module can perform data processing on the acquired donation information after receiving a related receiving instruction and information of a charity, then generate a digital donation certificate from the donation information after the data processing, and send the generated digital donation certificate or information corresponding to the digital donation certificate to the digital collection technology module, that is, transmit the generated digital donation certificate to the digital collection technology module in a picture or 3D data format. The donation information may include information about the object information, donation time, donation amount, donated object, and the like of the donated object, and the data processing may be at least one of processing manners such as data cleaning and data standardization.

In an alternative embodiment, in the process of generating the digital donation certificate based on the donation information, the certificate management system may obtain the target certificate format sent by the donation object, and then generate the digital donation certificate based on the donation information and the target certificate format.
Optionally, the certificate production module may obtain a target certificate format sent by the donated object when obtaining the donation information, where the target certificate format may be selected from a variety of selectable graphics or three-dimensional display modes built in the certificate production module, or may be customized by the donated object. And then, the certificate making module can customize and generate the digital donation certificate according to the donation information and the target certificate format and the personalized aesthetic requirements of the donation objects.
Further, in the process of generating the hash value corresponding to the digital donation certificate, the digital collection technology module may also use the target certificate format as key information while acquiring the object information, the donation date, the donation amount, and the donated object of the donation object corresponding to the digital donation certificate, so as to generate the hash value based on the object information, the donation date, the donation amount, the donated object, and the target certificate format of the donation object.
It should be noted that the donation certificate is made into a digital collection according to the personalized requirements of the donation subject, and more collection values are given to the donation certificate, so that the donation experience and novelty of the donation subject can be improved, and the attention of the social public to the charitable cause is promoted.
In an optional embodiment, in the process of verifying the authenticity of the target digital donation certificate based on the information stored in the blockchain, the certificate management system may calculate a hash value corresponding to the target digital donation certificate, and then determine a first target hash value corresponding to the query information in the certificate query instruction from the blockchain, so that the target digital donation certificate is determined to be authentic when the hash value corresponding to the target digital donation certificate is the same as the first target hash value, and the target digital donation certificate is determined to be abnormal when the hash value corresponding to the target digital donation certificate is different from the first target hash value.
Optionally, the first target module may first calculate the hash value of the obtained target digital donation certificate based on the donation information corresponding to the obtained target digital donation certificate, or the first target module may also calculate the hash value of the obtained target digital donation certificate based on the donation information corresponding to the obtained target digital donation certificate and the target certificate format. Then, the first target module may search the block chain for a hash value (i.e., a first target hash value) corresponding to the query information in the certificate query instruction, so that when the two hash values are the same, it is determined that the target digital donation certificate is authentic, whereas when the two hash values are different, it is determined that the target digital donation certificate is abnormal.
It should be noted that, by comparing the hash value corresponding to the target digital donation certificate with the hash value stored in the block chain, the validity verification of the authenticity of the target digital donation certificate is realized.
In an optional embodiment, in the process of determining the authority information of the target object and determining the first target module according to the authority information, if the authority information of the target object is the first authority information, the target object is determined to be the first target object, the certificate query module is determined to be the first target module, if the authority information of the target object is the second authority information, the target object is determined to be the second target object, and the certificate display module is determined to be the first target module, wherein the authority represented by the first authority information is higher than the authority represented by the second authority information.
In this embodiment, the authority information of the authorized user such as the relevant authority may be set as the first authority information in advance, and the authority information of the non-authorized user such as the individual or the financial institution may be set as the second authority information.
Optionally, the certificate query module is configured to provide a function of querying a donated certificate for an authoritative user (e.g., an external authority), that is, if the authority information of the target object is the first authority information, the certificate query module is determined as the first target module. For example, as shown in fig. 1, when a donation object transacts a certain service (e.g., deduction of tax and discount certificate), an external authority (i.e., the first target object) needs to synchronize donation certificate information of the donation object, so the external authority may perform system interfacing with a certificate query module, and the certificate query module may obtain a target digital authenticity donation certificate from the digital collection technology module and verify the target digital donation certificate according to keywords such as a donator identity or a certificate hash value in query information provided by the external authority.
Optionally, the certificate display module is configured to provide a function of querying a donation certificate for an unauthorized user (e.g., a donation object, a related financial institution), that is, if the authority information of the target object is the second authority information, the certificate display module is determined as the first target module. For example, as shown in fig. 1, when a donation object (i.e., the aforementioned second target object) or another inquiring party (i.e., the aforementioned second target object) needs to inquire or browse the digital donation certificate, the certificate display module may obtain the target digital donation certificate from the digital collection technology module through the certificate inquiry module according to the keywords such as the donor identification or the certificate number information in the inquiry information provided by the inquiring party, and perform authenticity verification on the target digital donation certificate through the certificate display module or the certificate inquiry module.
It should be noted that, because the first target module corresponds to the fed-back target mode, when the authority of the target object is higher, the target object is responded based on the certificate query module, and when the authority of the target object is lower, the target object is responded based on the certificate display module, so that accurate selection of the target modes corresponding to different target objects is conveniently achieved.
In an alternative embodiment, in the process of feeding back the target digital donation certificate to the target object in a target manner through the first target module, when the first target module is the certificate query module, the certificate management system may send the target digital donation certificate to the first target object, and when the first target module is the certificate display module, the certificate management system may display the target digital donation certificate to the second target object.
Optionally, when the first target module is the certificate query module, as shown in fig. 1, the certificate query module may directly send the target digital donation certificate to the first target object, so that the first target object performs operations such as backup and storage on the digital donation certificate, and when the first target module is the certificate display module, the certificate display module may avoid directly sending the target digital donation certificate to the second target object, but convert the target digital donation certificate into a form of a picture or a text, and then perform real certificate information display through terminal devices such as a mobile phone held by the second target object.
It should be noted that, by feeding back the digital donation certificate to be queried by the target object based on different manners, it is avoided that an object with low credibility easily forges the directly acquired target digital donation certificate or an object with high credibility hardly retains the target digital donation certificate in the form of a picture, which is caused by feeding back the target digital donation certificate to different target objects based on the same manner.
In an alternative embodiment, after displaying the target digital donation certificate to the second target object, the certificate management system may respond to a target certificate query command of a third target object, determine target query information based on the target certificate query command, then determine a third target hash value corresponding to the target identifier from the block chain, compare whether the second target hash value is the same as the third target hash value, and feed back a comparison result to the third target object, where the third target object is used to handle the pending service for the second target object, the target query information at least includes the target identifier provided by the second target object and the second target hash value, and the comparison result is used by the third target object to determine whether to handle the pending service for the second target object.
Optionally, when the donated object transacts the pending service in the related financial institution (i.e. the third target object), if the donated object needs to show the digital donation certificate of the donated object to the related financial institution, after viewing the digital donation certificate shown by the donated object, the related financial institution may determine, based on the digital donation certificate shown by the donated object, a target identifier (e.g. a donor identity identifier, a certificate number, etc.) and a second target hash value corresponding to the shown digital donation certificate, and then send a corresponding target certificate query instruction to the certificate management system for information verification. And then, determining a target identifier and a second target hash value from the target certificate inquiry command through the certificate display module, finding a third target hash value corresponding to the target identifier from the block chain, comparing the second target hash value with the third target hash value to obtain a comparison result, and sending the comparison result to a related financial institution. The related financial institutions can access the certificate inquiry website which is opened by the certificate management system to the outside so as to inquire the related digital donation certificates.
Optionally, as shown in fig. 1, if there is a node corresponding to the third target object in the blockchain, the third target object may also directly perform information interaction with the blockchain to obtain a third target hash value corresponding to the target identifier, so as to implement information check on the digital donation certificate displayed by the donation object.
Further, when the associated financial institution determines that the second target hash value is the same as the third target hash value, it may choose to handle the pending transaction for the donated object, and, conversely, it may refuse to handle the pending transaction for the donated object.
It should be noted that, by feeding back the certificate hash value comparison result based on the target certificate query instruction of the third target object, the applicability of the present application is improved, and the application range of the donated certificate is conveniently expanded.
Alternatively, as shown in fig. 3, an alternative application process of the present application is described. Optionally, the process of digital collection of the donation certificate may include the following steps:
1. and calling a certificate making module interface by a charitable organization which donates the donated object or the donated object, and transmitting the donated information to the certificate making module.
2. The certificate manufacturing module generates a corresponding digital donation certificate based on the donation information, and transmits the digital donation certificate to the digital collection technology module to perform digital collection casting.
3. The digital collection technical module calls a block chaining certificate storage intelligent contract and performs chaining certificate storage on key information (such as donation information, certificate format and the like) and the hash value of the digital donation certificate.
Further, as shown in fig. 3, when the inquiring party is an external authority, the process of inquiring and feeding back the digital donation certificate may include the following steps:
4. the external authority accesses the certificate query module and sends a certificate query instruction to query the certificate information.
5. The certificate inquiry module accesses the digital collection technology module and inquires the corresponding digital donation certificate according to the inquiry information in the certificate inquiry instruction.
6. And the digital collection technology module feeds back the corresponding digital donation certificate to the certificate inquiry module according to the information sent by the certificate inquiry module.
7. And the certificate inquiry module carries out authenticity verification on the digital donation certificate and sends the digital donation certificate to an external authority after the verification is passed.
Optionally, as shown in fig. 3, when the inquiring party is a donated object or other relevant organization, the process of inquiring and feeding back the digital donated certificate may include the following steps:
8. the donated object (or other relevant organization) accesses the credential presentation module and sends a credential query instruction to apply for viewing credential information.
9. The certificate display module accesses the certificate inquiry module and applies for inquiring the certificate information.
10. The certificate inquiry module accesses the digital collection technology module, inquires the corresponding digital donation certificate, verifies the authenticity of the acquired digital donation certificate, and then feeds the digital donation certificate back to the certificate display module after the verification is passed.
11. The certificate exposure module exposes the digital donation certificate to the donated object (or other relevant authority).
12. The related financial institution (i.e., the inquiring party in fig. 3) handling the pending service for the donated object may invoke the blockchain inquiry contract through the certificate display module, inquire the certificate information and the hash value stored in the chain based on the certificate label or the donator id obtained from the donated object and the hash value, and feed the inquired information back to the related financial institution through the certificate display module by the blockchain.
