Based on the above description, the embodiment of the present invention provides a revenue verification method based on a federated chain, which is mainly implemented based on the federated chain technology, where the federated chain is a novel application of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. is essentially a de-centralized database, that is, a string of data blocks that are generated by using a cryptographic method to correlate, and each data block includes a batch of transaction information for verifying the validity of the transaction information and generating the next block. The federation chain underlying platform may include processing modules for user management, basic services, intelligent contracts, operation monitoring, and the like. The user management module is responsible for identity information management of all blockchain participants, including maintenance of public and private key generation (account management), key management, maintenance of correspondence between the true identity of the user and alliance chain address (authority management), and the like. The specific implementation steps of the method comprise the steps that a terminal obtains income information of a target user, the income information of the target user comprises an identification of the target user and a income value of the target user, the income information of the target user is uploaded to a alliance chain, and when a income verification request aiming at the target user is received, income verification is carried out on the target user according to the income information of the target user stored in the alliance chain, and a verification result is obtained. In one implementation scenario, the coalition chain may be formed by a plurality of terminals of companies, each terminal of the company serves as a node in the coalition chain, each terminal of the company may collect income information of employees of the company and upload the income information of the employees into the coalition chain, the target user is any one of the employees of the company, and when the target user needs to perform income verification, the node in the coalition chain may query the income information of the target user in the coalition chain and complete corresponding verification. Optionally, in order to ensure confidentiality of employee income information, the node may upload the encrypted income information to the federation chain, encrypt the threshold when income needs to be verified, compare the value between the encrypted threshold and the value of the encrypted income information, if the value of the encrypted income information is greater than the encrypted threshold, determine that the value of the actual income information is greater than the threshold, and determine that the income verification result for the target user is verification passing, where the threshold may be used as a verification condition, and when the income value in the income information is greater than the threshold, determine that the verification condition is satisfied.
In summary, by adopting the revenue verification method based on the alliance chain, when the user is verified, the user is not required to provide corresponding revenue evidence, thus preventing the user from forging the revenue evidence, and the revenue verification is completed in the alliance chain, the manual participation links of the revenue evidence issuing and verification are removed, and the efficiency of the revenue evidence issuing and verification is greatly improved. And the encrypted income information is uploaded in the alliance, so that the income information of the user is kept secret, the verification is performed based on the encrypted income information during verification, a decryption link is not needed, and whether the income meets the requirement or not is verified on the premise of protecting personal privacy.
An embodiment of the present invention provides a revenue verification method based on a federation chain, referring to fig. 1, the revenue verification process based on the federation chain may include the following steps S101 to S103:
s101, acquiring income information of a target user by a terminal, wherein the income information of the target user comprises an identification of the target user and a income value of the target user.
In the embodiment of the invention, the terminal can acquire the income information of a plurality of users, the target user can be any one of the plurality of users, the income information of the target user can comprise the identification of the target user and the income value of the target user, and the income value can be a annual income value, a quarterly income value and a monthly income value, and can be specifically preset by a person using the terminal. The terminal can be mobile phone, computer, tablet personal computer, etc., which can be used as a node in the alliance chain, and the terminal can periodically obtain the income information of the target user, or obtain the income information of the target user when receiving the corresponding request.
In one implementation scenario, the terminal may specifically carry a personnel system of a company, where the personnel system may be connected to a salary system of the company to obtain salary data of each month of an employee in the salary system, and generate corresponding revenue information according to the salary data of the employee, where the employee of the company includes a target user.
S102, the terminal uploads the income information of the target user to the alliance chain.
In the embodiment of the invention, the terminal is used as a node in the alliance chain, and after acquiring the income information of the target user, the income information of the target user can be uploaded into the alliance chain.
In one implementation, the specific process of the terminal to uplink the income information of the target user may be that the terminal broadcasts the income information of the target user, so that the node in the coalition chain performs consensus verification on the income information of the target user, and if the node in the coalition chain passes the income information verification, the terminal packages the income information into blocks and links the blocks to the coalition chain.
In one implementation, in order to ensure confidentiality of the income information of the target user, the specific process of the terminal for uplink of the income information of the target user may be that the terminal encrypts the income information of the target user to obtain encrypted income information, the terminal broadcasts the encrypted income information in the coalition chain so that nodes in the coalition chain perform consensus verification on the encrypted income information, and if the nodes in the coalition chain pass the verification on the encrypted income information, the terminal packages the encrypted income information into blocks and links the blocks to the coalition chain. The terminal may encrypt the revenue value in the revenue information based on a preset encryption rule, for example, the revenue value is a monthly revenue value of the target user, the preset encryption rule is to double the value of the revenue value of the part with the revenue value smaller than 3000, and multiply the value of the part with the revenue value larger than 3000 by 3, when the revenue value of the target user is 2000, the encrypted value is 2x2000=4000, when the revenue value of the target user is 5000, the encrypted value is 2x3000+3x2000=12000, and by adopting the above encryption manner, the terminal may make the data stored in the coalition chain not be the actual revenue value of the target user, and when the terminal needs to invoke the actual revenue value of the target user, the terminal may decrypt the encrypted information stored in the coalition chain by adopting the decryption manner corresponding to the encryption manner to obtain the actual revenue value of the target user. By the method, the real income information of the user can be kept secret.
In one implementation, the specific process of the terminal to uplink the income information of the target user may also be that the terminal performs a segmentation process on the income value in the income information based on at least one preset segmentation value, so as to obtain a segmentation result, where the segmentation result includes a threshold interval where the income value in the income information is located, and the terminal uploads the segmentation result to the coalition chain. Specifically, the terminal broadcasts the segmentation result of the income information of the target user, so that nodes in the alliance chain perform consensus verification on the segmentation result, if the nodes in the alliance chain pass the segmentation result verification, the terminal packages the segmentation result into blocks, and links the blocks to the alliance chain. By the method, the section where the income of the target user is located can be uploaded instead of detailed income, and confidentiality of the income value of the user can be improved.
It should be noted that, in the process of performing the consensus check on the income information by the nodes in the alliance association, the consensus number may be preset, and when the number of nodes passing the consensus check is greater than the consensus number, the consensus check is determined to pass. Or, the consensus weight may be preset, and each node may have a different weight, and when the weight of the result of the consensus verification is greater than the preset consensus weight, it is determined that the verification passes, for example, there are 3 nodes in the federation chain, which are a first node, a second node and a third node, respectively, where the preset consensus weight is 5, the weight of the first node is 3, the weight of the second node is 3, and the weight of the third node is 1. If only the first node and the second node pass the common-knowledge verification, the weight can be determined to be 6 and larger than the preset common-knowledge weight, and if only the second node and the third node pass the common-knowledge verification, the weight can be determined to be 4 and smaller than the preset formula weight, and if the verification is determined not to pass, the uplink operation of the income information cannot be completed.
In one implementation scenario, the nodes in the coalition chain may be terminals of individual companies, each of which may carry personnel systems of the company. The terminal of each company can acquire the corresponding income information generated based on the actual compensation of the staff of the company, encrypt the income information and upload the income information into the alliance chain. So that each node in the federation chain records the encrypted revenue information. The node having the key to the revenue information may obtain the actual revenue value for the employee in the company by decrypting the encrypted revenue information.
S103, when the terminal receives a income verification request aiming at the target user, income verification is carried out on the target user according to income information of the target user stored in the alliance chain, and a verification result is obtained.
In the embodiment of the invention, after the terminal uploads the user identification and the travel ticket information to the blockchain, the terminal can receive the income verification request aiming at the target user. The terminal can acquire the income information of the target user in the alliance chain based on the identification of the target user, perform income verification on the target user according to the income information of the target user stored in the alliance chain, and acquire a verification result.
In one implementation, the revenue verification request further carries a revenue threshold, the revenue information of the target user stored in the coalition chain is an actual revenue value of the target user, the terminal detects whether the actual revenue value of the target user stored in the coalition chain is greater than the revenue threshold, if so, the terminal determines that the revenue verification result for the target user is verification passing, and if not, the terminal determines that the revenue verification result for the target user is verification failing. For example, the income threshold is 5000, the actual income value of the target user stored in the alliance chain is 6000, the terminal determines that the actual income value is greater than the income threshold, and the income verification result of the target user is verification pass.
In one implementation, the revenue verification request carries a revenue threshold, and the specific manner of performing revenue verification on the target user by the terminal according to the revenue information of the target user stored in the coalition chain is that the revenue threshold is uploaded to the coalition chain, and intelligent contracts in the coalition chain are called to analyze the revenue threshold and the encrypted revenue information to obtain an analysis result, wherein the analysis result comprises a magnitude relation between the revenue threshold and the revenue value of the target user; and if the analysis result indicates that the income threshold value is larger than the income value of the target user, determining that the income verification result of the target user is verification passing, and if the analysis result indicates that the income threshold value is smaller than or equal to the income value of the target user, determining that the income verification result of the target user is verification failing. For example, the value of the encrypted income information of the target user stored in the alliance chain is 12000, the income threshold carried by the income verification request is 6000, the terminal uploads the income threshold to the alliance chain, the intelligent contract encrypts the income threshold by adopting the same preset encryption rule for encrypting the income information of the target user, wherein the preset encryption rule can be a part with the income value smaller than 3000, the value of the preset encryption rule is doubled, the part with the income value larger than 3000 is multiplied by 3, the obtained encrypted income threshold is 3000×2+3000×3=15000, the intelligent contract determines that the income threshold after encryption is larger than the income value of the encrypted income information, and the income threshold is larger than the income value of the target user because the size relation among numbers is not changed after encryption, and returns the analysis result to the terminal, and the terminal determines that the income verification request does not pass according to the analysis result.
In one implementation, the revenue verification request carries a revenue threshold, and the specific manner of performing revenue verification on the target user by the terminal according to the revenue information of the target user stored in the coalition chain is that the terminal obtains the segmentation result of the target user stored in the blockchain based on the intelligent contract in the coalition chain, determines the magnitude relation between the revenue value of the revenue information of the target user and the revenue threshold according to the segmentation result, and determines that the verification result for the revenue verification request is verification passing if the magnitude relation indicates that the revenue value of the target user is greater than the revenue threshold. The segmentation result stored in the alliance chain can be subjected to segmentation processing on the revenue value in the revenue information in advance by the terminal based on at least one preset segmentation value to obtain the segmentation result, wherein the segmentation result comprises a threshold interval of the revenue value in the revenue information, and the segmentation result is uploaded to the alliance chain by the terminal. For example, the income value in the income information of the target user is 5000, the segmentation result of the terminal aiming at the income value in the income information is 4000-6000, the segmentation result is uploaded to the alliance chain, when the terminal receives the income verification request aiming at the target user, the income threshold value in the income verification request and the segmentation result of the target user are analyzed to obtain the magnitude relation between the income value of the target user and the income threshold value, if the income threshold value is 7000, the income value of the target user is determined to be smaller than the income threshold value, the income verification result of the terminal aiming at the target user is verification failure, if the income threshold value is 3000, the income value of the target user is determined to be larger than the income threshold value, and the terminal determines that the income verification result aiming at the target user is verification pass. By the method, the true income value of the target user can not be disclosed in the alliance chain, and when the income of the user needs to be verified, the verification is performed based on the income interval of the target user.
Referring to fig. 2, referring to the federation chain-based revenue verification system shown in fig. 2, the federation chain-based revenue verification system refers to a system for data sharing between nodes, and the federation chain-based revenue verification system may include a plurality of nodes 201, and the plurality of nodes 201 may refer to respective terminals in the federation chain-based revenue verification system. Each node may receive input information while operating normally and maintain shared data within the federated chain-based revenue verification system based on the received input information. In order to ensure information interworking within the federated chain-based revenue verification system, there may be an information connection between each node in the federated chain-based revenue verification system through which information may be transferred between the nodes. For example, when any node in the federation chain based revenue verification system receives input information, other nodes in the federation chain based revenue verification system acquire the input information according to a consensus algorithm, store the input information as data in shared data, so that the data stored on all nodes in the federation chain based revenue verification system are consistent.
For each node in the federated chain based revenue verification system, each node in the federated chain based revenue verification system may have a node identification corresponding thereto, and each node in the federated chain based revenue verification system may store node identifications of other nodes in the federated chain based revenue verification system for subsequent broadcasting of the generated block to other nodes in the federated chain based revenue verification system based on the node identifications of the other nodes. Each node can maintain a node identification list shown in the following table, and the node names and the node identifications are correspondingly stored in the node identification list. The node identifier may be an IP (Internet Protocol, protocol of interconnection between networks) address, and any other information that can be used to identify the node, and the IP address is only illustrated in table 1.
| Node name | Node identification |
| Node 1 | 117.114.151.174 |
| Node 2 | 117.116.189.145 |
| … | … |
| Node N | 119.123.789.258 |
Each node in the federation chain based revenue verification system stores one and the same federation chain. The alliance chain is composed of a plurality of blocks, see fig. 3, the alliance chain is composed of a plurality of blocks, the starting block comprises a block head and a block main body, the block head stores a version number of input information, a last block hash value and Merkle root nodes, and the block main body stores the input information; the next block of the starting block takes the starting block as a father block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the version number of the father block, the hash value of the last block and the Merkle root node, and the like, so that the block data stored in each block in the alliance chain are associated with the block data stored in the father block, and the safety of the input information in the block is ensured. In a specific implementation, revenue information uploaded by each node can be stored in each block.
When each block in the alliance chain is generated, when the node where the alliance chain is located receives the input information, checking the input information, storing the input information into a memory pool after the checking is completed, and updating a hash tree used for recording the input information; then, updating the update time stamp to the time of receiving the input information, trying different random numbers, and calculating the characteristic value for a plurality of 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 eigenvalue algorithm used to calculate eigenvalues; version number is version information of related block protocol in alliance chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value in a period of time, and is determined again after exceeding a fixed period of time; x is a random number; TARGET is a eigenvalue threshold that can be determined from nbits.
Thus, when the random number meeting the formula is calculated, the information can be correspondingly stored to generate the block head and the block main body, and the current block is obtained. And then, the node where the alliance chain is located respectively sends the newly generated blocks to other nodes in the alliance chain-based revenue verification system where the node is located according to the node identification of other nodes in the alliance chain-based revenue verification system, the other nodes verify the newly generated blocks, and after the verification is completed, the newly generated blocks are added into the stored alliance chain.
In the embodiment of the invention, the terminal acquires the income information of the target user, wherein the income information of the target user comprises the identification of the target user and the income value of the target user, the income information of the target user is uploaded into the alliance chain, and when a income verification request for the target user is received, the income verification is carried out on the target user according to the income information of the target user stored in the alliance chain, and a verification result is obtained. By implementing the method, the income value of the user can be conveniently verified, and the intelligence and the accuracy of the income value verification are improved.

s401, the terminal acquires income information of the target user, wherein the income information of the target user comprises an identification of the target user and a income value of the target user.
In the embodiment of the invention, the terminal can acquire the income information of a plurality of users, the target user can be any one of the plurality of users, the income information of the target user can comprise the identification of the target user and the income value of the target user, and the income value can be a annual income value, a quarterly income value and a monthly income value, and can be specifically preset by a person using the terminal. The terminal can be mobile phone, computer, tablet personal computer, and other electronic equipment, and can be specifically used as a node in the alliance chain.
In one implementation scenario, the terminal may specifically carry a personnel system of a company, where the personnel system may be connected to a salary system of the company to obtain salary data of each month of an employee in the salary system, and generate corresponding revenue information according to the salary data of the employee, where the employee of the company includes a target user.
S402, the terminal encrypts the income information of the target user to obtain encrypted income information.
In the embodiment of the invention, in order to ensure confidentiality of income information of a target user, a terminal can encrypt the income information of the target user to obtain encrypted income information, and specifically, the terminal can encrypt the income value in the income information based on a preset encryption rule, wherein the preset encryption rule can amplify or reduce the income value in the income information according to the rule, and the larger the income value is, the larger the encrypted income value is, namely, the original size relation of the numerical value is not changed after encryption. For example, the income value is the income value of the target user per month, the preset encryption rule is to double the income value of the part with the income value smaller than 3000, and the income value of the part with the income value larger than 3000 is multiplied by 3, when the income value of the target user is 2000, the encrypted value is 2×2000=4000, when the income value of the target user is 5000, the encrypted value is 2×3000+3×2000=12000, the terminal adopts the encryption mode, so that the data uploaded to the alliance chain is not the actual income value of the target user, and when the terminal needs to call the actual income value of the target user, the terminal can decrypt the encrypted income information by adopting the decryption mode corresponding to the encryption mode, so as to obtain the actual income value of the target user.
S403, the terminal broadcasts the encryption income information in the alliance chain so that nodes in the alliance chain perform consensus check on the encryption income information.
In the embodiment of the invention, the terminal encrypts the income information of the target user, and after obtaining the encrypted income information, the terminal can broadcast the encrypted income information in the alliance chain so as to enable the nodes in the alliance chain to carry out consensus verification on the encrypted income information.
In a specific implementation, the number of the consensus checks can be preset, and when the number of the nodes passing the consensus checks is greater than the number of the consensus checks, the passing of the consensus checks is determined. Or, the consensus weight may be preset, and each node may have a different weight, and when the weight of the result of the consensus verification is greater than the preset consensus weight, it is determined that the verification passes, for example, there are 3 nodes in the federation chain, which are respectively a first node, a second node and a third node, the preset consensus weight is 5, the weight of the first node is 3, the weight of the second node is 3, and the weight of the third node is 1. If only the first node and the second node pass the common-knowledge verification, the weight can be determined to be 6 and larger than the preset common-knowledge weight, and the verification passes the common-knowledge verification, if only the second node and the third node pass the common-knowledge verification, the weight can be determined to be 4 and smaller than the preset common-knowledge weight, and if the verification does not pass, the uplink operation of the income information can not be completed.
S404, if the node in the alliance chain passes the verification of the encryption income information, the terminal packages the encryption income information into blocks and links the blocks into the alliance chain.
In the embodiment of the invention, after the node in the alliance chain carries out consensus verification on the encryption income information, the terminal packages the encryption income information into blocks and links the blocks into the alliance chain.
In one implementation manner, in order to make the encryption income information uploaded by the terminal have an anti-counterfeiting effect, the specific manner that the terminal packages the encryption income information into blocks and links the blocks to the alliance chain may be that the terminal adopts an asymmetric encryption manner to perform secondary encryption on the encryption income information, that is, adopts a target private key to perform secondary encryption on the encryption income information and sends a target public key corresponding to the target private key to a node in the alliance chain, and the terminal packages the encryption income information after the secondary encryption into blocks and links the blocks to the alliance chain. By the method, other nodes in the alliance chain can decrypt the encrypted income information encrypted secondarily by adopting the target public key to determine that the identity of the terminal uploading the encrypted income information is the true identity, for example, after the terminal encrypts the encrypted income information by adopting the target private key, the format of the encrypted income information is changed, if the first format is changed to the second format, other nodes in the alliance chain can decrypt the encrypted income information by adopting the target public key, if the decrypted format is the first format, the encrypted income information can be determined to be uploaded by legal nodes, and if the decrypted format is not the first format, the encrypted income information can be determined to be uploaded by illegal nodes, and the asymmetric encryption mode is adopted to enable the data stored in the alliance chain to have anti-fake effect.
S405, the terminal generates an intelligent contract according to the encryption income information and uploads the intelligent contract to the alliance chain.
In the embodiment of the invention, after the terminal packages the encryption income information into the blocks and links the blocks into the alliance chain, the intelligent contract can be generated according to the encryption income information, the intelligent contract indicates the verification mode aiming at the encryption income information, and the terminal uploads the intelligent contract into the alliance chain, so that the intelligent contract can automatically analyze the income of the target user based on the income verification request aiming at the target user sent by the node and return the corresponding analysis result.
S406, when receiving the income verification request for the target user, the terminal verifies the income of the target user according to the income information of the target user stored in the alliance chain, and obtains the verification result.
In the embodiment of the invention, after the encrypted income information of the target user is stored in the alliance chain, the income verification request aiming at the target user can be received, and the income verification is carried out on the target user according to the income information of the target user stored in the alliance chain.
In one implementation, the revenue verification request carries a revenue threshold, and the specific manner of performing revenue verification on the target user by the terminal according to the revenue information of the target user stored in the coalition chain is that the revenue threshold is uploaded to the coalition chain, and intelligent contracts in the coalition chain are called to analyze the revenue threshold and the encrypted revenue information to obtain an analysis result, wherein the analysis result comprises a magnitude relation between the revenue threshold and the revenue value of the target user; and if the analysis result indicates that the income threshold value is larger than the income value of the target user, determining that the income verification result of the target user is verification passing, and if the analysis result indicates that the income threshold value is smaller than or equal to the income value of the target user, determining that the income verification result of the target user is verification failing. For example, the revenue value of the encrypted revenue information of the target user stored in the coalition chain is 12000, the revenue threshold carried by the revenue verification request is 6000, the terminal uploads the revenue threshold to the coalition chain, the intelligent contract encrypts the revenue threshold by adopting the same preset encryption rule for encrypting the revenue information of the target user, wherein the preset encryption rule is a part with the revenue value smaller than 3000, the value of the preset encryption rule is doubled, the part with the revenue value larger than 3000 is obtained, the encrypted revenue threshold is 3000×2+3000×3=15000, the intelligent contract determines that the encrypted revenue threshold is larger than the revenue value of the encrypted revenue information, and the intelligent contract determines that the revenue threshold is larger than the revenue value of the target user because the magnitude relation among the digits is not changed after encryption, and returns the analysis result to the terminal, and the terminal determines that the revenue verification request does not pass according to the analysis result.
In one implementation, the revenue verification request carries a revenue threshold, and the specific manner of performing revenue verification on the target user by the terminal according to the revenue information of the target user stored in the coalition chain is that the terminal obtains the segmentation result of the target user stored in the coalition chain based on the intelligent contract in the coalition chain, determines the magnitude relation between the revenue value of the revenue information of the target user and the revenue threshold according to the segmentation result, and determines that the verification result for the revenue verification request is verification passing if the magnitude relation indicates that the revenue value of the target user is greater than the revenue threshold. The segmentation result stored in the alliance chain can be subjected to segmentation processing on the revenue value in the revenue information in advance by the terminal based on at least one preset segmentation value to obtain the segmentation result, wherein the segmentation result comprises a threshold interval of the revenue value in the revenue information, and the segmentation result is uploaded to the alliance chain by the terminal. For example, the income value in the income information of the target user is 5000, the terminal segments the income value in the income information into 4000-6000, and uploads the segmented result to the alliance chain, when the terminal receives the income verification request for the target user, the income threshold in the income verification request and the segmented result of the target user are analyzed to obtain the magnitude relation between the income value of the target user and the income threshold, if the income threshold is 7000, the income value of the target user is determined to be smaller than the income threshold, the income verification result of the terminal for the target user is verification failure, if the income threshold is 3000, the income value of the target user is determined to be larger than the income threshold, and the terminal determines that the income verification result for the target user is verification passing. By the method, the true income value of the target user can not be exposed in the alliance chain, and when the income of the user needs to be verified, the verification is performed based on the income interval of the target user.
It should be noted that any other node in the federation chain may also receive the verification request for the target user, and verify the income of the target user by acquiring the income information of the target user in the federation chain in the same verification manner as the terminal verifies the target user in steps S401-406.
In one implementation scenario, the nodes in the coalition chain may be terminals of individual companies, each of which may carry personnel systems of the company. The terminal of each company can acquire the corresponding income information generated based on the actual compensation of the staff of the company, encrypt the income information and upload the income information into the alliance chain. As shown in fig. 5, the nodes in the federation chain include terminals of company a, company B and company C, and the terminals of company a, company B and company C are used as accounting consensus nodes in the federation chain, and can upload income information of employees of the company in the federation chain and perform consensus verification on the encrypted income information uploaded by other companies. The business party can be used as a verification node in the alliance chain, can acquire the encrypted income information in the alliance chain, can verify the income information of the target user based on the intelligent contract in the alliance chain, and provides corresponding service when the verification passes. For example, if the user a is an employee of the company a, and the user a sends a loan request to a bank (i.e., a verification node), the bank needs to verify whether the income of the user a is greater than a preset value, for example, 5000 yuan, the bank may send a income verification request to a federation chain, and an intelligent contract in the federation chain verifies whether the income of the user a is greater than the preset value based on a homomorphic encryption algorithm, if yes, information passing verification is returned to the bank, and if not, information failing verification is returned to the bank. Further, after the terminal provides the service corresponding to the target consumption item, a verification record for the revenue verification request is generated according to the provided service, and further, the verification record can be uploaded into a alliance chain, so that the verification result in the alliance chain can be directly checked when the target user is verified next time.
In the embodiment of the invention, the terminal acquires the income information of the target user, uploads the income information of the target user to the alliance chain, and when receiving the income verification request for the target user, the terminal performs income verification on the target user according to the income information of the target user stored in the alliance chain, and acquires a verification result. By adopting the revenue verification method based on the alliance chain, when the user is verified, the user is not required to provide corresponding revenue evidence, the user is prevented from forging the revenue evidence, the revenue verification is completed in the alliance chain, the manual participation link of the revenue evidence issuing and verification is removed, and the efficiency of the revenue evidence issuing and verification is greatly improved. And the encrypted income information is uploaded in the alliance chain, so that the income information of the user is kept secret, the verification is performed based on the encrypted income information during verification, a decryption link is not needed, and whether the income meets the requirement or not is verified on the premise of protecting personal privacy.
