When the node server 130 receives the seeker enlightenment publishing request of the user terminal 110, a seeker enlightenment for the seeker enlightenment publishing request is generated; then, the node server 130 broadcasts a person finding inspiring to the blockchain network to perform consensus verification for the person finding inspiring; after the consensus on the person finding inspiring in the blockchain network is achieved, the node server 130 stores the consensus block corresponding to the person finding inspiring into the blockchain of the blockchain network, so that the blockchain link points of the blockchain network issue the person finding inspiring. In practical applications, the user terminal 110 may specifically be a desktop terminal or a mobile terminal, and the mobile terminal may specifically be at least one of a mobile phone, a tablet computer, a notebook computer, and the like. The node server 130 may be implemented as a stand-alone server or a server cluster comprised of a plurality of servers.
As shown in fig. 2, in one embodiment, a flow diagram of a people-seeking heuristic publication method based on a blockchain is provided. The present embodiment is mainly illustrated by applying the method to the node server 130 in fig. 1. Referring to fig. 2, the people-seeking heuristic issuing method based on the blockchain specifically includes the following steps:
s210, when the person searching elicitation publishing request of the user terminal is obtained, the person searching elicitation aiming at the person searching elicitation publishing request is generated.
The seeker heuristic issue request may refer to a request generated by the user terminal 110 according to a seeker application filled by the user.
In a specific implementation, when a user needs to issue a seeker heuristic, the user may access a certain seeker platform by using the user terminal 110 and fill in seeker application information, such as missing person name, missing person shape and appearance, missing person portrait, contact person name, contact person contact information, and the like. Then, the user terminal 110 generates a seeker enlightenment issue request corresponding to the seeker application, and submits the seeker enlightenment issue request to the node server 130 corresponding to the homing platform.
When the node server 130 receives the seeker enlightenment publishing request of the user terminal, the node server 130 obtains the seeker application information in the seeker enlightenment publishing request, and generates the seeker enlightenment aiming at the seeker enlightenment publishing request according to the seeker application information.
S220, broadcasting the person finding inspirations to the block chain network so as to carry out consensus verification aiming at the person finding inspirations.
The consensus verification may refer to an authentication process for making each blockchain node in the blockchain network agree on the people-seeking heuristic based on a consensus system.
In practical applications, the common identity system may include a workload attestation mechanism (PoW), a rights and interests attestation mechanism (PoS), a stock authorization attestation mechanism (DPoS), a verification pool (PooI), a Practical Byzantine (PBFT), and the like.
In a specific implementation, after the node server 130 generates the seeker event release request, the node server 130 may further perform asymmetric encryption and digital signature on the seeker event to obtain the encrypted seeker event; the node server 130 then broadcasts the encrypted seeker heuristic into the blockchain network for consensus verification against the seeker heuristic.
More specifically, since the blockchain network is a distributed network. Therefore, in the process that the node server 130 broadcasts the encrypted seeker initials to the blockchain network, the node server 130 sends the encrypted seeker initials to the blockchain nodes adjacent to the node server 130, namely, the adjacent node servers through the network routing function, so that the adjacent node servers receive the encrypted seeker initials, decrypt and verify the encrypted seeker initials, and the decrypted seeker initials are obtained. Meanwhile, after receiving the encrypted seeker initiative of the node server 130, the adjacent node server continues to send the encrypted seeker initiative to the adjacent block chain node, and so on, thereby realizing the broadcast of the seeker initiative to the block chain network. In the process of performing consensus verification on the person finding inspiring, each blockchain node in the blockchain network performs consensus verification on the person finding inspiring based on a preset consensus system.
The consensus system used by each blockchain node in the blockchain network in this embodiment may be a workload certification mechanism, and when each blockchain node in the blockchain network receives the person finding heuristic, each blockchain node performs consensus operation. Specifically, after each block chain link point in the block chain network receives a person searching start event, the person searching start event is used as input information and the input information is verified, after the verification is completed, the input information is stored in a memory pool, and a hash tree used for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET
wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version (version number) is version information of related block protocols in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.
When the block chain link points calculate to obtain the random numbers meeting the formula, generating a block head and a block main body based on the person searching inspirations to obtain a consensus block, encrypting and broadcasting the consensus block to a block chain network, and further providing the block chain nodes except the block chain link points to obtain the consensus block, thereby completing the person searching inspirational consensus verification so that all the block chain link points in the block chain network achieve consensus on the person searching inspirational inspirations.
And S230, after the consensus on the person searching inspirations is achieved in the block chain network, storing the consensus blocks corresponding to the person searching inspirations into the block chains of the block chain network so that the block chain link points of the block chain network release the person searching inspirations.
Wherein the consensus blocks may refer to blockchain blocks generated based on the people heuristic after consensus on the people heuristic is achieved in the blockchain network.
In a specific implementation, when the node server 130 is a block link point that first completes the consensus operation in the block link network, the node server 130 uses a block created based on the person finding heuristic as the consensus block, encrypts and broadcasts the consensus block to the block link network, so that the block link nodes except the node server 130 can obtain the consensus block and perform effective verification, and after the effective verification passes, the block link nodes of the consensus block are in the respective block links.
Meanwhile, the node server 130 stores the common identification block corresponding to the person seeking heuristic into the block chain of the block chain network, specifically, the node server 130 generates the common identification block on the block chain according to the block head characteristic value of the first block in the block chain, and further stores the common identification block into the block chain of the block chain network; the first block is a previous block of the consensus block, and the consensus block is used for recording the people searching inspiration.
Of course, the node server 130 may not be the blockchain node that performs the consensus operation first in the blockchain network. The node server 130 may obtain the consensus blocks broadcasted by the chain nodes of other blocks that have performed the consensus operation first, and perform block validity verification on the consensus blocks, for example, verify the update time, data structure, data content, and other information of the consensus blocks. When the block is verified legally, the common identification block is stored in the block chain of the node server 130. Therefore, the person searching initials are synchronized to the block chains of the block chain nodes in the block chain network, and the person searching initials can be issued by reading the person searching initials stored in the block chains.
According to the person finding inspiring publishing method based on the block chain, when a person finding inspiring publishing request of a user terminal is obtained, a person finding inspiring aiming at the person finding inspiring publishing request is generated; then, the node server broadcasts a person finding inspiring to a block chain network so as to carry out consensus verification aiming at the person finding inspiring; after the consensus on the people searching inspirations is achieved, the consensus blocks corresponding to the people searching inspirations are stored in the block chains of the block chain network, so that the people searching inspirations are distributed to the block chain link points, and therefore in the process of publishing the people searching inspirations, all the block chain link points in the block chain network can accurately share the same people searching inspirations published by the publisher, the publisher is prevented from publishing the people searching inspirations on all the people searching platforms respectively, and the publishing efficiency of the people searching inspirations is improved.
In one embodiment, the people-seeking heuristic publishing method based on the block chain specifically further includes: inquiring a to-be-issued seeker heuristic in a block chain of a block chain network; determining a target publishing node identifier of the seeker heuristic to be published; and issuing the seeker inspirations to be issued according to the target issuing node identification.
The to-be-issued person finding inspiring can refer to a person finding inspiring which needs to be issued on a person finding platform.
The target publishing node identifier may refer to an identifier of a block chain node which is specified by a user in advance and used for publishing the to-be-published seeker heuristic.
In practical application, the target publishing node identifier may refer to an access website of the parent searching platform corresponding to the block link node.
In specific implementation, the node server 130 detects whether the block chain has the seeker heuristic to be issued, and if the block chain has the seeker heuristic to be issued, the seeker heuristic to be issued is acquired; then, determining the target publishing node identification of the seeker heuristic to be published; further determining a block chain node which is specified by a user in advance and used for issuing the to-be-issued seeker inspirations; and finally, issuing the seeker introspection to be issued according to the target issuing node identification. Specifically, when the node server 130 obtains the block link point identifier of the node server 130, then the node server 130 determines whether the block link point identifier of the node server 130 matches the target publishing node identifier, and if the block link point identifier matches the target publishing node identifier, it is determined that the node server 130 designates the block link point for publishing the seeker heuristic to be published for the user, and the seeker heuristic to be published is published to the parent platform corresponding to the node server 130.
For example, assuming that there are a parent searching platform a, a parent searching platform B and a parent searching platform C, when a user needs to publish a person searching heuristic to the parent searching platform B, the user submits a person searching heuristic publishing request for the person searching heuristic to the node server 130 through the user terminal 110, where the person searching heuristic publishing request has an access website identified by the target publishing node as the parent searching platform B. After receiving the person finding inspiring release request, the node server 130 generates a person finding inspiring for the person finding inspiring release request, and broadcasts the person finding inspiring to the blockchain network to perform consensus verification for the person finding inspiring; after the consensus on the seeker inspirations is achieved in the block chain network, the seeker inspirations are used as the seeker inspirations to be issued, and the consensus blocks corresponding to the seeker inspirations to be issued are stored in the block chains of the block chain network, so that the seeker inspirations are issued by the block chain link points of the block chain network.
When the node server 130 detects that the seeker heuristic to be issued exists in the block chain, the node server 130 determines that the target issuing node identifier of the seeker heuristic to be issued is the access website of the parent seeking platform B; further determining a parent searching platform B which is specified by a user in advance and used for publishing the seeker initiatives to be published; and then, according to the target publishing node identification, publishing the seeker heuristic to be published. More specifically, when the node server 130 obtains the block link point identifier of the node server 130 itself as the parent searching platform a, at this time, the node server 130 determines that the block link point identifier of the node server 130 is not matched with the target publishing node identifier, and does not publish the to-be-published person finding introspection on the parent searching platform corresponding to the node server 130.
When the node server 130 obtains the block link point identifier of the node server 130 itself as the parent searching platform B, at this time, the node server 130 determines that the block link point identifier of the node server 130 matches with the target publishing node identifier, determines that the node server 130 designates the block link point for publishing the seeker heuristic to be published for the user, and publishes the seeker heuristic to be published to the parent searching platform B corresponding to the node server 130.
Fig. 3 provides a schematic release flow diagram of a block chain-based seeker heuristic release method, as shown in fig. 3, specifically including the following steps: s310, inquiring the to-be-issued seeker inspirations in the block chain of the block chain network. S320, determining the target publishing node identification of the seeker heuristic to be published. And S330, issuing the seeker introspection to be issued according to the target issuing node identifier.
Because the detailed implementation process of each step is described in detail in the above embodiments, it is not described herein again.
According to the technical scheme of the embodiment, a person-seeking inspiring matter to be issued in a block chain of a block chain network is inquired; determining a target publishing node identifier of the seeker heuristic to be published; and finally, issuing the person finding initiatives to be issued according to the target issuing node identification, so that a user can select a proper person finding platform to issue the person finding initiatives, the situation that the issuer needs to issue the person finding initiatives on each person finding platform is avoided, and the issuing efficiency of the person finding initiatives is improved.
In one embodiment, step S220 specifically includes: acquiring a public key of a receiving node; encrypting the person finding inspirations by using the public key of the receiving node to obtain the encrypted person finding inspirations; generating a private key, and signing the person finding inspirations by using the private key to obtain a digital signature; the digital signature is used for the receiving node to check and find people and inspires; and sending the encrypted person finding inspirations and the digital signatures to a receiving node.
The receiving node is a block chain node used for receiving the person finding inspirations in the block chain network.
In a specific implementation, before the node server 130 broadcasts the seeker initiative to the blockchain network, the node server 130 needs to encrypt the seeker initiative, and the node server 130 obtains a public key of the receiving node; then, the node server 130 encrypts the person finding heuristic by using the public key of the receiving node to obtain the encrypted person finding heuristic; then, the node server 130 generates a private key corresponding to the node server 130, and signs the person-seeking inspirations by using the private key according to a preset digital signature algorithm to obtain a digital signature; the digital signature is used by the receiving node to verify whether the seeker elicitation received from the node server 130 has been tampered with. Finally, the node server 130 packages the encrypted seeker initiatives and digital signatures and sends them to the receiving node.
It should be noted that, after the receiving node receives the encrypted seeker initiative and the digital signature of the node server 130, the receiving node decrypts the encrypted seeker initiative by using the private key corresponding to the public key of the receiving node, so as to obtain the seeker initiative of the node server 130. Meanwhile, the receiving node verifies the digital signature corresponding to the person finding heuristic by using the public key of the node server 130, and then judges whether the person finding heuristic received from the node server 130 is tampered in the transmission process; if the operation is falsified, the above-mentioned person-searching inspirations are abandoned.
According to the technical scheme of the embodiment, the node server obtains the public key of the receiving node; encrypting the person searching inspirations by using the public key of the receiving node to obtain the encrypted person searching inspirations; generating a private key, and signing the person finding inspirator by using the private key to obtain a digital signature; the encrypted seeker initials and the encrypted digital signatures are sent to the receiving nodes for the receiving nodes to receive and encrypt, so that the safety of the seeker initials in data transmission among the block chain link points in the block chain network is improved, the stability of the seeker initials for issuing is prevented from being reduced due to data tampering, and the issuing efficiency of the seeker initials is improved.
In one embodiment, the step of signing the seeker heuristic with the private key to obtain the digital signature specifically comprises: generating an information abstract of the person-finding inspiring according to a preset abstract algorithm; and encrypting the information digest by using the private key to obtain the digital signature.
The digest algorithm may refer to an algorithm for generating a digest of information of the original data, for example, a hash algorithm. In practical applications, the digest algorithm may be SHA256 algorithm (a kind of hash algorithm).
In a specific implementation, the process that the node server 130 signs the seeker inspirations by using the private key of the node server 130 to obtain the digital signature specifically includes: the node server 130 generates an information summary for the seeker's introspection according to a preset summary algorithm.

The to-be-cancelled people-seeking inspiring can be a people-seeking inspiring needing to be cancelled on a parent-seeking platform.
In a specific implementation, when a user needs to cancel a previously issued seeker inspiration on a seeking platform, the user uses the user terminal 110 to select a to-be-cancelled seeker inspiration that needs to be cancelled on the seeking platform. Then, the user terminal 110 generates a seeker enlightenment canceling request corresponding to the seeker enlightenment to be canceled for the seeker enlightenment to be canceled, and then the user terminal 110 sends the seeker enlightenment canceling request to the node server 130 for the node server 130 to receive.
After receiving the seeker initiatory revocation request, the node server 130 broadcasts the seeker initiatory revocation request to the block chain link points in the block chain network, and the node server 130 can further perform asymmetric encryption and digital signature on the seeker initiatory revocation request to obtain the encrypted seeker initiatory revocation request; then, the node server 130 broadcasts the encrypted seeker enlightening revocation request into the blockchain network to perform consensus verification on the seeker enlightening revocation request.
In the process that the node server 130 broadcasts the encrypted seeker enlightening revocation request to the block chain network, the node server 130 sends the encrypted seeker enlightening revocation request to a block chain link point adjacent to the node server 130, namely an adjacent node server, through a network routing function, so that the adjacent node server receives the encrypted seeker enlightening revocation request, decrypts and verifies the encrypted seeker enlightening revocation request, and the decrypted seeker enlightening revocation request is obtained. Meanwhile, after receiving the encrypted seeker enlightening revocation request from the node server 130, the adjacent node server continues to send the encrypted seeker enlightening revocation request to the adjacent block chain node, and so on, thereby realizing that the seeker enlightening revocation request is broadcast to the block chain network. In the process of performing consensus verification on the person finding inspiring revocation request, each blockchain node in the blockchain network performs consensus verification on the person finding inspiring revocation request based on a preset consensus system.
In this embodiment, the consensus system used by each blockchain node in the blockchain network is a workload certification mechanism, and when the node server 130 is a blockchain link point that first completes consensus operation in the blockchain network, the node server 130 uses a block created based on the person-finding inspiring revocation request as a consensus block, encrypts and broadcasts the consensus block to the blockchain network, so that the blockchain link points of other blockchain nodes obtain the consensus block and perform effective verification, and after the effective verification passes, the respective blockchains of the consensus blocks are verified. Meanwhile, the node server 130 stores the consensus block corresponding to the people-seeking inspiring cancellation request into the block chain of the block chain network.
Of course, the node server 130 may not be the blockchain node that performs the prior consensus operation in the blockchain network. At this time, the node server 130 may obtain the consensus blocks broadcasted by the block link nodes that have performed the consensus operation first in the block chain network, and perform block validity verification on the consensus blocks, for example, verify the update time, data structure, data content, and other information of the consensus blocks.

S630, broadcasting the person-seeking inspiring updated data to a block chain network so as to carry out consensus verification on the person-seeking inspiring updated data. And S640, after the consensus on the person-searching inspiring update data in the block chain network is achieved, storing the consensus blocks corresponding to the person-searching inspiring update data into the block chains of the block chain network, so that the block chain nodes update the person-searching inspiring to be updated according to the person-searching inspiring update data.
The to-be-updated person finding inspirations can be person finding inspirations needing to be updated on the person finding platform.
In a specific implementation, when a user needs to associate a previously issued seeker enlightenment on a homing platform, the user uses the user terminal 110 to select the seeker enlightenment to be updated which needs to be updated on the homing platform and fill in data which needs to be updated, such as a missing person photo and the like. Then, the user terminal 110 generates a person-seeking heuristic update request corresponding to the person-seeking heuristic to be updated and the data to be updated, and then the user terminal 110 sends the person-seeking heuristic update request to the node server 130 for the node server 130 to receive.
After receiving the seeker enlightenment canceling request, the node server 130 determines seeker enlightenment updating data of the seeker enlightenment to be updated according to the seeker enlightenment updating request; then, the person-seeking brought event update data is broadcasted to the block chain link points in the block chain network, and the node server 130 can also carry out asymmetric encryption and digital signature on the person-seeking brought event update data to obtain encrypted person-seeking brought event update data; then, the node server 130 broadcasts the encrypted seeker inspiring update data into the blockchain network to perform consensus verification on the seeker inspiring update data.
In the process that the node server 130 broadcasts the encrypted seeker initiative update data to the blockchain network, the node server 130 sends the encrypted seeker initiative update data to a blockchain point adjacent to the node server 130, namely an adjacent node server, through a network routing function, so that the adjacent node server receives the encrypted seeker initiative update data, decrypts and verifies the encrypted seeker initiative update data, and the decrypted seeker initiative update data is obtained.

Meanwhile, the node server 130 stores the consensus blocks corresponding to the data of the people-seeking inspiring update into the block chain of the block chain network.
Of course, the node server 130 may not be the blockchain node that performs the consensus operation first in the blockchain network. At this time, the node server 130 may obtain the consensus block broadcasted by the link node of the block that first completes the consensus operation in the blockchain network, and perform block validity verification on the consensus block, for example, verifying the update time, data structure, data content, and other information of the consensus block. When the block is validated, the common identification block is stored in the block chain of the node server 130. Therefore, the data updating of the to-be-updated person finding initials corresponding to the person finding initials updating request is realized by synchronizing the person finding initials updating data to the block chains of each block chain node in the block chain network, and each block chain node can update the data of the to-be-updated person finding initials by reading the person finding initials updating data stored in the block chains.

The predicted portrait photograph may be a portrait photograph obtained by predicting the current appearance of a missing person.
Wherein the photo taking time may refer to the time of a missing person portrait photo. In practical applications, the photo taking time of the missing person portrait photo may be the age of the missing person when the missing person portrait photo is taken.
In a specific implementation, in the process of generating the person-seeking inspiring for the person-seeking inspiring issuing request by the node server 130, the node server 130 may further determine, according to the person-seeking inspiring issuing request, missing person information in the person-seeking inspiring that the user needs to issue. Wherein, the node server 130 determines the missing person portrait photo and the photo taking time of the missing person portrait photo in the missing person information; then, the node server 130 judges whether the shooting time of the missing person portrait photo exceeds a preset time threshold value up to the present time according to the photo shooting time and the current time; in practical applications, the time threshold may be 10 years. When the shooting time of the missing person portrait photo exceeds the preset time threshold value, the node server 130 calls a preset portrait aging picture generation model to predict the current appearance of the missing person according to the missing person portrait photo and the shooting time of the missing person portrait photo, and then generates a predicted portrait photo. The image aging picture generation model can be a picture generation model obtained by training a neural network model.
