Description

Technical Field

[0001] The present application relates to the fields of artificial intelligence development technology and financial technology, and in particular to a blockchain-based rights distribution method, device, computer equipment and storage medium. Background Art

[0002] In the financial field, the distribution of benefits is one of the common marketing strategies of financial institutions, which aims to enhance user stickiness, improve user activity and loyalty by giving users specific discounts, rewards or benefits. These benefit distribution scenarios are widely used in banks, insurance, securities and various financial technology platforms, including but not limited to credit card points redemption, membership privileges, financial product discounts, etc.

[0003] At present, with the digital development of financial services, the issues of user identity identification and privacy protection in the process of rights issuance have become increasingly prominent. In the scenario of financial rights issuance, it is usually necessary to verify the identity of the user to ensure the accurate issuance of rights, but this process is often accompanied by the collection, storage and use of user personal information, which increases the risk of privacy leakage. In addition, the multiple links and entities involved in the process of financial rights issuance also increase the difficulty of privacy protection. From user registration, identity verification, rights issuance to subsequent use and redemption, each link may become a weak link in privacy leakage.

[0004] However, existing technologies and management methods cannot fully ensure the security of user privacy. Therefore, it is necessary to explore more secure and efficient privacy protection solutions to meet the increasingly severe challenges of financial privacy protection. Summary of the invention

[0089] It should be noted that the blockchain-based rights issuance method provided in the embodiment of the present application is generally executed by a server / terminal device, and accordingly, the blockchain-based rights issuance device is generally set in the server / terminal device.

[0090] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to the implementation requirements.

[0091] Continue to refer Figure 2 , showing a flowchart of an embodiment of a blockchain-based rights issuance method according to the present application. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted. The blockchain-based rights issuance method provided in the embodiment of the present application can be applied to any scenario where rights issuance is required, and the blockchain-based rights issuance method can be applied to products in these scenarios, for example, rights issuance in the financial insurance field. The blockchain-based rights issuance method includes the following steps:

[0092] Step S201, receiving a zero-knowledge proof input by a user; wherein the zero-knowledge proof is proof information generated based on the qualification proof information input by the user.

[0093] In this embodiment, the blockchain-based rights distribution method is run on an electronic device (e.g. Figure 1The server / terminal device shown in the figure) can obtain the zero-knowledge proof of the user input through a wired connection or a wireless connection. It should be noted that the above-mentioned wireless connection method may include but is not limited to 3G / 4G / 5G connection, Wi F i connection, Bluetooth connection, Wi MAX connection, Zigbee connection, UWB (Ultra Wi deband) connection, and other wireless connection methods currently known or to be developed in the future. The executor of the present application may specifically be a rights issuance system, which may be referred to as the system hereinafter. The present application can be applied to business scenarios of rights issuance of financial insurance, and the rights may include tokens, coupons, etc.

[0094] Specifically, the above-mentioned qualification certification information is the information used to prove that the conditions for the issuance of benefits are met. Users can upload qualification certification information (such as ID card photos, income certificates, etc.) that prove that they meet the conditions for the issuance of benefits through the interface or API provided by the system. These qualification certification information will be encrypted or desensitized to ensure that personal sensitive information is not directly exposed. Then, the user uses a zero-knowledge proof library (such as Zokrates, libsnar k, etc.) to build a zero-knowledge proof based on the qualification certification information. Among them, the zero-knowledge proof contains proof that the user meets specific conditions, but does not contain any specific information (such as age, income amount).

[0095] Zero-knowledge proof technology is a cryptographic protocol that allows one subject to prove the authenticity of a statement to another subject without revealing the specific content of the statement. In the equity issuance scenario, service providers can use zero-knowledge proofs to verify whether a user meets the issuance conditions without knowing the user's detailed information. For example, zero-knowledge proofs can be used to verify whether a user's age meets a certain limit without knowing the user's actual age.

[0096] Step S202: verifying the zero-knowledge proof based on a preset target verification algorithm.

[0097] In this embodiment, the target verification algorithm is specifically a zero-knowledge proof verification algorithm. After receiving the zero-knowledge proof input by the user, the system verifies the validity of the zero-knowledge proof by using the built-in zero-knowledge proof verification algorithm. After the zero-knowledge proof verification is passed, the user's qualification status is recorded using a smart contract.

[0098] Step S203: If the zero-knowledge proof passes the verification, an initial equity certificate is generated based on the smart contract pre-deployed on the target blockchain platform.

[0099] In this embodiment, if it is detected that the zero-knowledge proof passes the verification, the user's qualifications are determined to be confirmed, and the rights issuance operation will be automatically executed according to the smart contract pre-deployed on the target blockchain platform. The rights issuance operation includes generating a new rights certificate (such as a token, coupon ID) on the blockchain and associating it with the user's anonymous identity. Among them, the above-mentioned new rights certificate is the above-mentioned initial rights certificate. In addition, the deployment process of the smart contract will be further described in detail in the subsequent specific embodiments of this application, and will not be elaborated on here.

[0100] Blockchain is a decentralized distributed ledger technology that can record the transactions and usage of equity issuance and ensure the immutability and traceability of data. By recording the transactions of equity issuance on the blockchain, decentralized equity management and verification can be achieved, reducing human intervention and errors. Smart contracts can automate the process of equity issuance and verification, reducing manual operations and time consumption, and improving efficiency and responsiveness. Through automated processes, fast equity issuance and verification can be achieved, improving user experience.

[0101] Step S204: Obtain an anonymous identity corresponding to the user.

[0102] In this embodiment, an anonymous identity corresponding to the user will be generated in advance. The specific process of generating the anonymous identity will be described in further detail in the subsequent specific embodiments of this application, and will not be elaborated on here. Among them, the anonymous identity is a method of decoupling the user's real identity from the anonymous identity. By generating a unique anonymous identity, the identity can be used for authentication and tracking during the rights issuance process without exposing the user's real identity information, which can protect the user's privacy and data security, while allowing the rights issuance system to perform necessary verification and control.

[0103] Step S205: Generate a corresponding associated equity certificate based on the initial equity certificate and the anonymous identity.

[0104] In this embodiment, the initial equity certificate and the anonymous identity identifier may be associated, for example, concatenated, to generate a corresponding associated equity certificate.

[0105] Step S206, encrypt the associated equity certificate based on a preset homomorphic encryption strategy to obtain a corresponding target equity certificate.

[0106] In this embodiment, the above homomorphic encryption strategy may specifically adopt full homomorphic encryption or Paillier encryption. When generating the equity certificate, the associated equity certificate is encrypted by using homomorphic encryption technology to obtain the encrypted target equity certificate.

[0107] Step S207: issuing the target equity certificate to the user.

[0108] In this embodiment, the encrypted target equity certificate is sent to the user. Since the target equity certificate remains secure during transmission and storage, even if it is intercepted, it cannot be directly decrypted to obtain the content. This effectively achieves the safe and efficient issuance of equity without exposing user personal information, which is beneficial to improving user experience and system security.

[0109] This application first receives the zero-knowledge proof input by the user; wherein the zero-knowledge proof is the proof information generated according to the qualification proof information input by the user; and the zero-knowledge proof is verified based on the preset target verification algorithm; if the zero-knowledge proof passes the verification, an initial equity certificate is generated based on the smart contract pre-deployed on the target blockchain platform; then the anonymous identity corresponding to the user is obtained; then the corresponding associated equity certificate is generated based on the initial equity certificate and the anonymous identity; subsequently, the associated equity certificate is encrypted based on the preset homomorphic encryption strategy to obtain the corresponding target equity certificate; finally, the target equity certificate is issued to the user. This application verifies the zero-knowledge proof input by the received user by using the target verification algorithm. If the zero-knowledge proof passes the verification, the target equity certificate to be distributed will be generated based on the use of smart contracts, anonymous identities and homomorphic encryption strategies. When the target equity certificate is subsequently issued to the user, it is protected by anonymous identities and homomorphic encryption, so that the user's sensitive information no longer needs to be directly exposed, effectively reducing the risk of user information leakage and improving the security of user privacy.

[0110] In some optional implementations, before step S203, the electronic device may further perform the following steps:

[0111] Get the input smart contract code corresponding to the equity issuance.

[0112] In this embodiment, the smart contract code can be a contract code written by relevant business personnel using a smart contract programming language according to actual business needs. The smart contract code defines the rules, conditions, verification logic and data structure of the equity issuance and equity certificate.

[0113] The smart contract code is tested based on a preset testing strategy.

[0114] In this embodiment, the above-mentioned testing strategy includes unit testing and integration testing. The processing process of unit testing includes: testing each functional module of the smart contract by writing test cases to ensure its functional correctness. The processing process of integration testing includes: deploying the smart contract into the test environment, performing integration testing with other systems or contracts, and verifying whether its interaction with other components meets expectations.

[0115] If the smart contract code passes the test, the smart contract code is compiled based on the development tool of the target blockchain platform to obtain the corresponding smart contract.

[0116] In this embodiment, the development tool may be a Solidity compiler or a T Ruffle framework. If the smart contract code is detected to pass the test, the smart contract code is compiled using the development tool of the target blockchain platform to generate a deployable bytecode, i.e., the smart contract.

[0117] The smart contract is deployed in the target blockchain platform.

[0118] In this embodiment, one or more nodes are selected on the blockchain network as the entry point for contract deployment. Then, the compiled smart contract is deployed to the blockchain using the API or command line tool of the target blockchain platform to complete the deployment process of the smart contract. In addition, the deployed smart contract can also be verified to ensure the smooth deployment of the smart contract. Specifically, the contract address can be queried on the blockchain browser to verify whether the contract has been successfully deployed and contains the expected code and data. Or some sample transactions can be executed to verify the performance of the contract logic in the actual environment.

[0119] This application obtains the input smart contract code corresponding to the equity issuance; then tests the smart contract code based on a preset test strategy; if the smart contract code passes the test, the smart contract code is compiled based on the development tool of the target blockchain platform to obtain the corresponding smart contract; and the smart contract is subsequently deployed and processed in the target blockchain platform. After obtaining the input smart contract code corresponding to the equity issuance, if it is detected that the smart contract code passes the test, the smart contract code is compiled based on the development tool of the target blockchain platform to obtain the corresponding smart contract, so as to quickly and accurately complete the construction of the smart contract, thereby improving the construction intelligence and construction accuracy of the smart contract. The subsequent deployment and processing of the smart contract in the target blockchain platform can ensure the deployment accuracy of the smart contract.

[0120] In some optional implementations of this embodiment, before step S204, the electronic device may further perform the following steps:

[0121] Determine whether a registration request triggered by the user is received.

[0122] In this embodiment, the registration request is a request for identity registration triggered by a user in the system.

[0123] If so, call the preset cryptography library to generate a public-private key pair; wherein the public-private key pair includes a public key and a private key.

[0124] In this embodiment, the selection of the cryptographic library is not specifically limited and can be determined according to actual business usage requirements, for example, any one of OpenSSL, Bouncy Cast le, etc. can be selected. For a pair of public and private key pairs generated by the cryptographic library, the public key is used to encrypt messages and verify signatures, and the private key is used to decrypt messages and generate signatures.

[0125] The public key is obtained from the public-private key pair, and a hash value of the public key is calculated.

[0126] In this embodiment, the hash value of the public key can be calculated by using a preset hash algorithm, wherein the hash algorithm can adopt the SHA-256 hash algorithm.

[0127] The anonymous identity corresponding to the user is generated based on the hash value.

[0128] In this embodiment, the hash value of the generated public key can be used as the anonymous identity of the user, thereby reducing storage space and improving query efficiency. Anonymous identity is a method of decoupling the user's real identity from the anonymous identity. By generating a unique anonymous identity, the identity can be used for authentication and tracking during the rights issuance process without exposing the user's real identity information. This method can protect the user's privacy and data security while allowing the rights issuance system to perform necessary verification and control.

[0129] The anonymous identity is stored.

[0130] In this embodiment, the anonymous identity can be stored together with other non-sensitive information of the user in a database outside the blockchain, such as MySQL, MongoDB, etc. Among them, other non-sensitive information of the user may include nicknames, email addresses, etc. In addition, in order to ensure the security of the database, appropriate encryption and access control measures can be further taken to prevent unauthorized access and data leakage.

[0131] This application determines whether a registration request triggered by the user is received; if so, calls a preset cryptographic library to generate a pair of public-private key pairs; wherein the public-private key pair includes a public key and a private key; then obtains the public key from the public-private key pair, and calculates the hash value of the public key; then generates the anonymous identity corresponding to the user based on the hash value; and subsequently stores and processes the anonymous identity. After receiving a registration request triggered by a user, this application will intelligently call a preset cryptographic library to generate a pair of public-private key pairs, then obtain the public key from the public-private key pair, and calculate the hash value of the public key, and then generate the anonymous identity corresponding to the user based on the hash value, so as to quickly and intelligently generate the anonymous identity of the user, thereby improving the intelligence of the generation of the anonymous identity. The anonymous identity will also be stored and processed later to ensure the data security of the anonymous identity. In addition, in the process of issuing rights and interests, by using anonymous identity for authentication and tracking, there is no need to expose the real identity information of the user, thereby protecting the privacy and data security of the user.

[0132] In some optional implementations, after step S207, the electronic device may further perform the following steps:

[0133] Determine whether a rights usage request corresponding to the target rights certificate triggered by the user is received.

[0134] In this embodiment, the above-mentioned rights and interests use request may be a request triggered by the user in the system for using the target rights and interests corresponding to the target rights and interests certificate. After receiving the rights and interests use request triggered by the user, the system will automatically trigger the multi-factor verification process.

[0135] If so, obtain verification information corresponding to the user; wherein the verification information includes the user's device information, geographic information, and target behavior feature information.

[0136] In this embodiment, the user's device information can be collected through HTTP request headers, browser fingerprints, device IDs, etc. to generate device fingerprints. In addition, the corresponding geographic location is parsed according to the user's IP address, or the user is requested to authorize the acquisition of GPS coordinates to obtain the precise location. In addition, the user's behavior characteristics are analyzed through the user's historical operation records, operation frequency, operation mode, etc. to obtain the corresponding target behavior characteristic information.

[0137] Obtain a target information type corresponding to the verification information.

[0138] In this embodiment, the target information types include device information types, geographic information types, and behavior feature information types.

[0139] Pre-stored information corresponding to the user is acquired based on the target information type.

[0140] In this embodiment, the pre-stored information is standard device information, geographic location range, and behavior pattern template respectively corresponding to the device information type, geographic information type, and behavior characteristic information type provided by the user during registration.

[0141] The verification information is verified based on the pre-stored information.

[0142] In this embodiment, the collected verification information is compared with the pre-stored information corresponding to the user. If all the verification information passes the comparison, that is, it meets the preset security threshold corresponding to the pre-stored information, the verification information is determined to have passed the verification; otherwise, the verification information is determined to have failed the verification.

[0143] If the verification information passes the verification, the benefit usage request is responded to and processed.

[0144] In this embodiment, only when it is detected that all verification information has passed the verification, the system will allow the user to continue the operation and respond to the benefit use request; otherwise, the benefit use request will be rejected and further additional security measures will be triggered, such as secondary verification, account locking, etc.

[0145] This application determines whether a rights use request corresponding to the target rights certificate triggered by the user is received; if so, obtains verification information corresponding to the user; wherein the verification information includes the device information, geographic information and target behavior feature information of the user; then obtains the target information type corresponding to the verification information; then obtains the pre-stored information corresponding to the user based on the target information type; subsequently verifies the verification information based on the pre-stored information; if the verification information passes the verification, responds to the rights use request. After receiving the rights use request corresponding to the target rights certificate triggered by the user, this application obtains the verification information corresponding to the user, then obtains the pre-stored information corresponding to the user based on the target information type corresponding to the verification information, and then verifies the verification information based on the pre-stored information, so as to automatically and intelligently perform user identity authentication by combining multiple factors, thereby improving the accuracy and reliability of identity authentication. If the verification information passes the verification, the system will allow the user to continue the operation and respond to the rights use request, thereby improving the security of processing the rights use request, thereby improving the security and protection capabilities of the system.

[0146] In some optional implementations, after step S207, the electronic device may further perform the following steps:

[0147] Receive the encrypted equity certificate input by the user.

[0148] In this embodiment, after detecting that the verification information has passed the verification, the user can further input the encrypted equity certificate obtained through the equity issuance process in the system interface.

[0149] The type of requirement information corresponding to the equity verification is obtained, and based on the type of requirement information, information is extracted from the encrypted equity certificate to obtain corresponding target requirement information.

[0150] In this embodiment, the above-mentioned demand information type is an information type generated according to the demand for equity verification, and may include, for example, a certificate ID, validity period, usage conditions, etc. Correspondingly, the above-mentioned target demand information is the certificate ID, validity period, usage conditions, etc. corresponding to the above-mentioned encrypted equity certificate.

[0151] A corresponding target query condition is constructed based on the target demand information.

[0152] In this embodiment, query processing can be constructed based on the obtained target demand information to obtain the corresponding target query conditions. For certain types of queries (such as range queries), specific encryption techniques or index structures, such as Bloom filters, interval trees, etc., may be further required to optimize query efficiency.

[0153] A preset credential database is queried based on the target query condition to obtain search results matching the target requirement information.

[0154] In this embodiment, an encrypted query can be performed in the credential database using the target query conditions to find the credentials that match the target query conditions, i.e., the search results. Among them, encrypted search technologies such as homomorphic encryption, searchable encrypted indexes, etc. can be used to search the credential database without decrypting the data. In addition, the encrypted query can include performing complex operations on the encrypted data to find the credentials that match the target query conditions.

[0155] The validity of the search result is verified.

[0156] In this embodiment, the validity of the search results is verified by obtaining the signature, hash value, timestamp and other information of the search results and comparing them with the signature, hash value or timestamp of a known legal certificate.

[0157] If the search result passes the validity verification, the target equity corresponding to the encrypted equity certificate is written off.

[0158] In this embodiment, during the entire rights and interests verification process, the content of the encrypted credential rights and interests is always kept encrypted and will not be leaked to unauthorized parties. In addition, the verification operation only involves the processing and comparison of encrypted data, and does not directly decrypt user data, thereby achieving safe and efficient rights and interests verification processing under privacy protection.

[0159] The present application receives the encrypted equity certificate input by the user; then obtains the type of demand information corresponding to the equity verification, and extracts the information of the encrypted equity certificate based on the type of demand information to obtain the corresponding target demand information; then constructs the corresponding target query condition based on the target demand information; and queries the preset voucher database based on the target query condition to obtain the search result matching the target demand information; subsequently verifies the validity of the search result; if the search result passes the validity verification, the target equity corresponding to the encrypted equity certificate is written off. After receiving the encrypted equity certificate input by the user, the present application extracts the information of the encrypted equity certificate based on the type of demand information corresponding to the equity verification to obtain the target demand information, and constructs the corresponding target query condition based on the target demand information, and then queries the preset voucher database based on the target query condition to obtain the search result matching the target demand information, and if it is detected that the search result passes the validity verification, the target equity corresponding to the encrypted equity certificate is written off, so as to achieve efficient, safe and accurate completion of the response processing of the equity use request, and effectively ensure the processing standardization and processing security of the equity verification processing.

[0160] In some optional implementations of this embodiment, the electronic device may further perform the following steps:

[0161] Call the preset monitoring node.

[0162] In this embodiment, multiple monitoring nodes are pre-deployed in the blockchain network on the target blockchain platform, and these monitoring nodes are responsible for capturing the equity transaction data on the target blockchain platform in real time.

[0163] The equity transaction data on the target blockchain platform is obtained based on the monitoring node.

[0164] In this embodiment, the monitoring node obtains the transaction data of equity issuance and use in real time by monitoring the broadcast of the blockchain network or querying the blockchain API to obtain the above-mentioned equity transaction data.

[0165] The transaction data is analyzed based on a preset data analysis tool to determine whether there is abnormal behavior data in the equity transaction data.

[0166] In this embodiment, the monitored equity transaction data can be analyzed in real time by using data analysis tools, and compared with pre-set thresholds to timely discover abnormal behaviors. Among them, the thresholds for abnormal behaviors such as transaction quantity, amount, frequency, etc. are set according to business needs and security standards.

[0167] If so, the abnormal behavior data is screened out from the equity transaction data, and corresponding target alarm information is generated based on the abnormal behavior data.

[0168] In this embodiment, the above abnormal behavior data can be filled into a preset alarm information template to generate corresponding target alarm information. The template content of the above alarm information template can be written and generated according to actual abnormal alarm requirements.

[0169] The target alarm information is sent to relevant personnel.

[0170] In this embodiment, the above-mentioned relevant personnel may specifically be the management personnel responsible for the abnormal management of rights and interests. The target alarm information may be sent by using emails, text messages, etc.

[0171] This application calls a preset monitoring node; then obtains the equity transaction data on the target blockchain platform based on the monitoring node; then analyzes the transaction data based on a preset data analysis tool to determine whether there is abnormal behavior data in the equity transaction data; if so, screens out the abnormal behavior data from the equity transaction data, and generates corresponding target alarm information based on the abnormal behavior data; and subsequently sends the target alarm information to relevant personnel. This application implements real-time monitoring of the target blockchain platform and obtains the equity transaction data on the target blockchain platform through the use of a monitoring node, and then analyzes the transaction data based on a preset data analysis tool. If it is detected whether there is abnormal behavior data in the equity transaction data, an alarm mechanism will be automatically triggered, and the corresponding target alarm information will be generated based on the abnormal behavior data and sent to relevant personnel, so as to promptly notify relevant personnel to resolve the abnormality, thereby helping to ensure the safe and stable operation of the system.

[0175] Perform statistical analysis and trend analysis on the equity-related data to obtain corresponding data analysis results.

[0176] In this embodiment, the statistical analysis refers to statistical analysis of the collected rights-related data, such as calculating the total amount of rights issued, the average amount and other indicators. The trend analysis refers to analyzing the time trend of rights issuance and use, and understanding the use of rights and user behavior. The data analysis results include statistical analysis results and trend analysis results.

[0177] The data analysis results are evaluated to obtain corresponding evaluation results.

[0178] In this embodiment, the above-mentioned evaluation process includes evaluating the effect of the rights issuance based on the data analysis results, such as indicators such as user satisfaction and system performance, so as to obtain corresponding evaluation results.

[0179] Generate a corresponding equity assessment report based on the data analysis results and the assessment results.

[0180] In this embodiment, the data analysis result and the evaluation result can be input into a preset evaluation report template to generate a corresponding equity evaluation report. The evaluation report template can be a template file generated according to actual equity evaluation business needs.

[0181] The equity evaluation report is stored and processed.

[0182] In this embodiment, there is no specific limitation on the storage method of the equity evaluation report. For example, a local database, a cloud server, or other storage methods may be used.

[0183] This application collects equity-related data from the target blockchain platform; then performs statistical analysis and trend analysis on the equity-related data to obtain corresponding data analysis results; then evaluates and processes the data analysis results to obtain corresponding evaluation results; subsequently generates a corresponding equity evaluation report based on the data analysis results and the evaluation results; and finally stores and processes the equity evaluation report. This application performs statistical analysis and trend analysis on the equity-related data collected from the target blockchain platform to obtain corresponding data analysis results, and then evaluates and processes the data analysis results to obtain corresponding evaluation results, so as to realize automatic and intelligent data analysis and evaluation processing of equity-related data in the blockchain, which is conducive to providing strong support for the safe, stable operation and continuous optimization of the system. In addition, the corresponding equity evaluation report will be intelligently generated based on the data analysis results and the evaluation results, thereby improving the generation efficiency of the equity evaluation report. And the equity evaluation report will also be stored and processed to ensure the security of the generated equity evaluation report.

[0184] In some optional implementations, artificial intelligence technology can be used to conduct risk assessment and anomaly detection in the equity issuance process to promptly detect and prevent potential fraud. By establishing machine learning models and rule engines, the data flow and behavior patterns of equity issuance can be monitored in real time, thereby improving the security and reliability of the system.

[0185] In some optional implementations, the user information obtained is subject to the user's consent and complies with relevant laws and policies.

[0186] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0187] It should be emphasized that in order to further ensure the privacy and security of the above-mentioned target equity certificate, the above-mentioned target equity certificate can also be stored in a node of a blockchain.
