Description

Information processing method and information verification method and device based on block chain

Technical Field

The application relates to the technical field of blockchains, in particular to an information processing method based on a blockchain. The present application also relates to a blockchain-based information processing apparatus, a blockchain-based information verification method, a blockchain-based information verification apparatus, a computing device, and a computer-readable storage medium.

Background

A blockchain is a network of distributed databases and multiple nodes. The data stored in the blockchain can only be added in blocks by the consensus algorithm, and cannot be modified and deleted. Therefore, blockchains are widely used in scenarios where there is a need for data reliability.

In the related art, in order to reduce the offending task in the blockchain, information verification may be performed on information of a gateway node of the blockchain in advance, for example, real-name verification is performed, and a result of the information verification is stored. In this way, in the case that the user initiates a task request to the blockchain through the gateway node, the information of the gateway node can be verified by using the result of the information verification. If the verification is not passed, the gateway node is likely to be illegally set. Accordingly, the task request initiated by the gateway node is likely to be for an offending task, and the blockchain may refuse to respond to the task request. Thus, verification of information to the gateway node may reduce the handling of violations by the blockchain.

However, in the above information authentication, the gateway node is a node providing a network access service. Therefore, in order to secure security, it is necessary to set and maintain network access services specifically for blockchain or periodically perform maintenance on information verification for a node providing network access services to a third party. Thus, the information verification of the blockchain has the problem of high implementation difficulty.

It should be understood that, although the terms first, second, etc. may be used in one or more embodiments of the present application to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, a first may also be referred to as a second, and similarly, a second may also be referred to as a first, without departing from the scope of one or more embodiments of the present application. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

In the present application, a blockchain-based information processing method is provided, and the present application relates to a blockchain-based information processing apparatus, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.

Fig. 1 is a flowchart of a blockchain-based information processing method, which is applied to a blockchain supervision node according to an embodiment of the present application, and specifically may include the following steps:

s102, receiving information to be verified sent by the client, and verifying the information to be verified to obtain a verification result.

In a specific application, the authentication may be a real-name authentication, such as KYC (Know your Customer, knowledge of your user, a mechanism that requires full real-name for the user being served). And, the client may actively transmit the information to be verified under the condition of receiving the information to be verified submitted by the user, or the client may transmit the information to be verified under the condition of receiving the verification notification or the verification failure notification transmitted by the supervision node. The timing of sending the verification notification may be various. For example, verification notifications may be actively sent by a supervising node of the blockchain to clients of the blockchain. Alternatively, illustratively, the supervising node of the blockchain may send verification notifications to each client of the blockchain upon receiving address generation requests sent by the clients. On the basis, the client side displays the received verification notification, and the user submits the information to be verified in the client side according to the displayed verification notification, so that the client side sends the information to be verified submitted by the user to the supervision node of the blockchain.

The information to be verified is information for indicating the authenticity of the user identity, and specifically may include at least one of information such as a user identity card number, a user video, a user image and the like. The specific mode of verifying the information to be verified by the supervision node of the blockchain can be various exemplary, and the supervision node of the blockchain can input the information to be verified into a recognition model obtained by pre-training to obtain a verification result. The identification model is a neural network model trained by using identity information in an identity information base and verification result labels. Alternatively, the supervision node may send the information to be verified to the specified verification platform and receive the verification result returned by the specified verification platform. The appointed verification platform can be a platform which can be used for user real-name verification by a security management department, a financial supervision department and the like.

S104, obtaining the on-chain address of the login client and the client information.

In particular applications, the manner in which the on-chain address of the login client is obtained may be varied. For example, if the on-chain address of the login client is sent together with the information to be verified, the on-chain address is received. Alternatively, for example, if login information of the client is received, the on-chain address of the login client may be read from the login information, to obtain the on-chain address of the login client. Alternatively, if the client requests generation of an on-chain address, the generated on-chain address may be used as the on-chain address of the login client. And, the client information may include information such as a client identifier, client device information, and a summary of the information to be verified.

And S106, if the verification is successful according to the verification result, binding the address on the chain and the client information, and storing the binding result into the blockchain.

In particular applications, storing binding results to the blockchain may be various. For example, the binding result may be stored directly to the blockchain, or a validity period may be added to the binding result, and the binding result added with the validity period may be stored to the blockchain. The validity period is the validity period of the binding result. The second case will be described in detail in the form of alternative embodiments for ease of understanding and rational layout. In addition, in order to improve security, any data stored in the blockchain may be first encrypted and then stored.

And, the blockchain may be any of a public chain, a federated chain, and a private chain. Wherein, the public chain has no admission rule in general, any user can process tasks by using the public chain, and the execution of illegal tasks by the public chain, such as tasks for propagating illegal information, is easy to cause. In this regard, the scheme provided by the embodiment of the application can verify the user using the public chain through the binding result, so that the security of the public chain is improved, and the execution of the public chain on the illegal task is reduced. The authority verification of the alliance chain and the private chain is to verify the gateway node of the blockchain, and the problem of high difficulty in information verification realization exists. In this regard, the scheme provided by the embodiment of the application can directly realize the information verification of the blockchain from the verification dimension of the address on the chain without specially setting and maintaining the network access service, thereby reducing the difficulty in realizing the information processing and verification of the blockchain. Therefore, the embodiment of the application has wide application scenes.

In an optional implementation manner, the blockchain-based information processing method provided in the embodiment of the present application may further include the following steps:

if the verification failure is determined according to the verification result, sending a notification of the verification failure to the client.

In a specific application, the notification of the authentication failure may include information indicating the authentication failure, a cause of the authentication failure, and the like. After receiving the notification of the verification failure, the client can display the notification of the verification failure, and the user can submit the information to be verified again according to the notification of the verification failure. The embodiment can facilitate the user to know whether the verification is successful or not in time, thereby improving the user experience.

In an alternative embodiment, the binding the address and the client information on the chain and storing the binding result in the blockchain may specifically include the following steps:

binding the address on the chain and the client information to obtain a binding result, and determining a binding timestamp;

determining the validity period of a binding result based on the binding timestamp and a preset validity period;

and adding the validity period into the binding result, and storing the binding result added with the validity period into the blockchain.

Binding on-chain addresses and client information may be particularly diverse in particular applications. For example, a correspondence between the addresses on the chain and the client information may be established, where the correspondence is a binding result. The correspondence may specifically be in the form of a correspondence table or pointer. Alternatively, for example, client information may be added to the on-chain address to obtain a binding result. Any manner of binding the on-chain address and client information may be used in the present application, and the present embodiment is not limited in this regard. In addition, storing the binding result added with the validity period to the blockchain specifically may include: and processing the binding result added with the validity period into a block, transmitting the block to a verification node of the block chain, and broadcasting the block in the block chain if the verification node of the block chain determines that the block accords with a preset block format. On this basis, if each node in the blockchain receives the block and the node does not store the block, the node stores the block and records the event about storing the block into the blockchain ledger.

And, the binding timestamp refers to a point of time when the binding result is obtained. The specific manner of determining the validity period of the binding result based on the binding timestamp and the preset validity period may be various. For example, the binding timestamp and the preset validity period may be directly used as the validity period of the binding result. Alternatively, as an example, a point in time at which a time span after and between the binding timestamp and the binding timestamp is a preset validity period may be determined as the validity period of the binding result. For example, if the binding timestamp is 2021, 9, 14, 12:00 and the preset validity period is 30 days, the validity period of the binding result is 2021, 10, 14, 12:00.

The embodiment can ensure that the binding result has timeliness, so that in the process of verifying the information based on the blockchain, the addresses on the chain exceeding the validity period can be automatically classified as invalid addresses, and the verification result corresponding to the verification request of the invalid addresses is verification failure; and if the task request is initiated by the invalid address, the task corresponding to the task request is forbidden to be executed, so that the safety is further improved.

Receiving an address generation request sent by a client;

sending a verification notification to the client, wherein the verification notification is used for notifying the client to send information to be verified according to the verification notification;

determining whether the information to be verified is verified;

if yes, the response address generation request is forbidden.

In a specific application, in order to reduce the situations that the task request sent by the user is prohibited from being executed and reduce the situations that verification notifications are sent to a large number of clients that have already been verified, the verification notifications may be sent to the clients when an address generation request sent by the client, that is, when the user applies for an address on the chain, is received. On the basis, in order to reduce the situation that the illegal user falsely uses the verification information to further improve the safety, a principle that the verified user only has one on-chain address can be adopted, namely the information to be verified corresponds to the on-chain address one by one, and further the information processing is carried out according to the principle that the on-chain address corresponds to the binding result one by one. Specifically, it may be determined whether the information to be verified has been verified; if yes, the response address generation request is forbidden.

In addition, the principle of one-to-one correspondence between the information to be verified and the addresses on the chain can be applied to the embodiment of fig. 1 of the present application, that is, before the information to be verified is verified in the embodiment of fig. 1, it can be determined whether the information to be verified has been verified; if yes, sending a notice of verification failure to the client, and if not, executing a step of verifying the information to be verified.

generating a private key corresponding to the address generation request by using a specified random algorithm;

correspondingly, the obtaining the address on the link of the login client may specifically include the following steps:

generating a public key corresponding to the address generation request by using a first encryption algorithm based on the private key;

based on the public key, an on-chain address of the login client is generated using a second encryption algorithm.

In a specific application, the specified random algorithm, the first encryption algorithm and the second encryption algorithm are all irreversible algorithms, namely asymmetric encryption algorithms, namely inputs of the algorithms cannot be deduced through outputs of the algorithms, and safety of a private key, a public key and addresses on a chain can be guaranteed. In addition, if the information to be verified is determined not to be verified, the information to be verified is not verified, and the principle that the information to be verified corresponds to the addresses on the chain one by one is met. Thus, the steps of this embodiment may be performed to generate a corresponding on-chain address for the generation request, which is sent to the client, and the user logs in to the client using the on-chain address. Thus, the generated is the on-chain address of the login client.

The method and the device generate the on-chain address of the login client for the user conforming to the principle that the information to be verified corresponds to the on-chain address one by one, so that the condition that the illegal user imports the verification information can be reduced, and the safety is further improved.

For easy understanding, the embodiment of fig. 1 and some optional embodiments are described in detail below with reference to a flow of a blockchain-based information processing method according to another embodiment of the present application shown in fig. 2.

As shown in fig. 2, an information processing method based on a blockchain, which is applied to a supervision node of the blockchain, may include the following steps:

starting; initiating real-name verification of addresses on a chain, and receiving information to be verified submitted by a user;

verifying whether the information to be verified meets real-name verification requirements or not; if yes, binding the address, the client information and the validity period of verification on the chain; if not, the verification fails.

The steps in this embodiment are similar to the steps in the embodiment of fig. 1 and the optional embodiments of part of fig. 1, and the same parts are not described herein again, and detailed descriptions of the embodiment of fig. 1 and the optional embodiments of part are described above. The difference is that the expression is different for the sake of brevity, in particular: starting, which is equivalent to client start-up operation or blockchain start-up operation; initiating real-name verification of the address on the chain, which is equivalent to sending verification notification to the client; receiving information to be verified submitted by a user, which is equivalent to receiving the information to be verified sent by a client; verifying whether the information to be verified meets the real-name verification requirement is equivalent to verifying the information to be verified to obtain a verification result; binding the address on the chain, the client information and the verified validity period, which is equivalent to binding the address on the chain and the client information to obtain a binding result, determining a binding timestamp, determining the validity period of the binding result based on the binding timestamp and a preset validity period, adding the validity period into the binding result, and storing the binding result added with the validity period into the blockchain; the verification failure is equivalent to sending a notification of the verification failure to the client.

Fig. 3 is a flowchart of a block chain based information verification method, applied to a block chain verification node, according to an embodiment of the present application, where the method may include the following steps:

s302, receiving a verification request sent by a client, and analyzing the verification request to obtain the address on the chain to be verified.

In a particular application, the validation request may be a request to validate an address on a chain, a task request, and so on. Accordingly, the manner in which the authentication request is parsed to obtain the on-chain address to be authenticated may be varied. For example, if the verification request is a request for verifying an address on a chain, a preset regularization algorithm may be used to extract a keyword in the verification request, where the extracted keyword is the address on the chain to be verified; or matching the verification request with a preset dictionary, wherein the character which is successfully matched is the address on the chain to be verified; or extracting the character at the appointed position of the verification request to obtain the on-chain address to be verified. Alternatively, if the validation request is a task request, and the task request is typically signed by the user's private key, for example. Therefore, the private key in the task request can be read, the private key is processed by the first encryption algorithm, the public key can be obtained, and then the public key is processed by the second encryption algorithm, so that the on-chain address to be processed is obtained.

In addition, the on-chain address to be verified may include the on-chain address of the login client, and the on-chain address of another user interacting with the user using the client.

S304, searching a binding result binding the address on the chain to be verified from binding results stored in the blockchain according to the address on the chain to be verified.

The binding result is generated after binding the address on the chain and the client information based on the verification result of the client.

In a specific application, the step of binding the address on the chain with the client information to generate the address on the chain may specifically include any one of the steps of the blockchain-based information processing method provided in the embodiment of fig. 1 and the optional embodiment of fig. 1. Searching the binding result bound with the address on the chain from the binding results stored in the blockchain according to the address on the chain specifically comprises the following steps: comparing the binding result of the block chain account book record stored by the verification node with the address on the chain to be verified, and if the address on the chain corresponding to the binding result is the same as the address on the chain to be verified, determining to find the binding result of the address on the chain to be verified; if the on-chain address corresponding to the binding result is different from the on-chain address to be verified, determining that the binding result of the on-chain address to be verified is not found.

In addition, the binding result contains client information, so that the client information of the client sending the verification request can be obtained, the candidate binding result bound with the client information is searched from the binding results stored in the blockchain, and further the binding result bound with the address on the chain is searched in the candidate binding result. Therefore, the binding is screened once by using the client information, and the searching efficiency can be improved.

S306, if the binding result of the address on the chain to be verified is found, the verification is determined to be successful.

If the binding result of the to-be-verified on-chain address is found, it indicates that the to-be-verified on-chain address is the on-chain address that is verified and verified successfully in the embodiment of fig. 1 and the alternative embodiment of fig. 1, so that the on-chain address to be verified corresponding to the verification request can be determined to be verified successfully. If the search result is not found, determining that verification fails. In addition, after determining that the authentication is successful, the authentication node may send a notification of the authentication success to the client; in the case that the authentication request is a task request, after determining that the authentication is successful, the authentication node may execute a task corresponding to the task request.

For easy understanding, the method provided in the embodiment of the present application will be further described below by taking a flowchart of the method for processing and verifying information applied to a blockchain as an example, which is provided in an embodiment of the present application as shown in fig. 4.

As shown in fig. 4, an embodiment of the present application provides a flow of an information processing and verification method applied to a blockchain, where the blockchain includes a client, a supervision node, and a verification node, and the method may include:

S402, the client sends information to be verified to the supervision node.

S404, the supervision node verifies the received information to be verified to obtain a verification result.

S406, the supervision node obtains the in-chain address of the login client and the client information.

S408, the supervision node binds the address on the chain and the client information under the condition that the verification is successful according to the verification result, and stores the binding result into the blockchain.

S410, the client sends a verification request to the verification node.

S412, the verification node analyzes the received verification request to obtain the on-chain address to be verified.

S414, the verification node searches the binding result of the address on the chain to be verified from the binding results stored in the blockchain according to the address on the chain to be verified.

S416, if the verification node finds out the binding result of the address on the chain to be verified, the verification node determines that the verification is successful.

The steps S402 to S416 in this embodiment are the same as those described in the foregoing embodiment of fig. 1, the optional embodiment of fig. 1, the embodiment of fig. 2, and the optional embodiment of fig. 2, and are not described herein again, and detailed descriptions of the same steps in the foregoing embodiment of fig. 1, the optional embodiment of fig. 2, and the optional embodiment of fig. 2 are described in detail.

In an alternative embodiment, the binding result includes a validity period;

correspondingly, if the binding result of the address on the chain to be verified is found, the verification is determined to be successful, which specifically includes the following steps:

if the binding result of the address on the chain to be verified is found, reading the validity period from the found binding result;

determining whether the address on the chain to be verified is in the validity period or not based on the validity period and the current time point;

if so, the verification is determined to be successful.

The embodiment can automatically classify the addresses on the chain exceeding the validity period as invalid addresses, and the verification result corresponding to the verification request of the invalid addresses is verification failure; and if the task request is initiated by the invalid address, the task corresponding to the task request is forbidden to be executed, so that the safety is further improved.

Also, the specific manner of determining whether the on-chain address to be verified is within the validity period based on the validity period and the current point in time may be various, and is specifically described below in the form of alternative embodiments.

In an alternative embodiment, the validity period includes: a point in time of failure;

correspondingly, the determining whether the address on the chain to be verified is in the validity period based on the validity period and the current time point specifically comprises the following steps:

Comparing the current time point with the failure time point, if the current time point exceeds the failure time point, determining that the address on the face to be verified is not in the valid period, otherwise, determining that the address on the face to be verified is in the valid period.

The expiration time point may specifically include a date and a time point. Illustratively, the failure time point is 2022, 3, 15, 22:00, and the current time point is 2022, 3, 15, 22:01, and the current time point exceeds the failure time point. In addition, the above time point may be accurate to seconds, and the accuracy of the time point is not limited in this embodiment.

In an alternative embodiment, the validity period may include: obtaining a time stamp and a preset effective duration of a binding result;

calculating a time span between the time stamp and the current time point;

and determining whether the address on the chain to be verified is in the validity period according to the size relation between the time span and the preset validity period.

If the time span is larger than the effective duration, determining that the address on the chain to be verified is not in the effective duration, otherwise, determining that the address on the chain to be verified is in the effective duration. Illustratively, the binding timestamp is 2021, 9, 14, 12:00, the preset effective duration is 30 days, and the current time point is 2021, 10, 16, 12:00. Thus, the time span between the time stamp and the current time point is 32 days, which is greater than the preset validity period by 30 days, and thus, it is determined that the on-chain address to be verified is not within the validity period. The embodiment can determine whether the on-chain address to be verified is in the validity period through the time span between the time stamp and the current time point.

In an optional implementation manner, the blockchain-based information verification method provided in the embodiment of the present application may further include the following steps:

if the binding result of the address on the chain to be verified is not found, sending a notification of verification failure to the client.

For easy understanding, the block chain-based information verification method provided in the embodiment of the present application is further described by taking a flowchart of another block chain-based information verification method provided in another embodiment of the present application as an example, and integrating the above-mentioned embodiment of fig. 3 and some optional embodiments of fig. 3.

As shown in fig. 5, another embodiment of the present application provides a flow of a blockchain-based information verification method, applied to a blockchain verification node, the method may include the following steps:

A task starts; analyzing to obtain the addresses on the chains corresponding to the tasks;

whether the address on the chain corresponding to the block chain end verification task passes real name verification or not; if the real name authentication is passed, determining whether the timeliness of the real name authentication is qualified; if the task is qualified, the verification is successful, and the task is executed;

if the real name verification is not passed, returning information of verification failure; and if the timeliness is unqualified, returning information of verification failure.
