Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the specification, as detailed in the appended claims.
The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used herein 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, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
For any open platform, the third-party application can be authorized to promote the service volume, so that the third-party application has the function of calling the platform capacity to execute the related service. For this reason, the development platform needs to have the capability of authorizing third party applications.
Traditional application authorization is typically performed privately, for example, an authorization agreement is privately signed between an application and a platform, the platform provides a token related to the application, and the application can access and invoke a service capability related to the platform by providing the token.
However, although the application authorization can improve the platform traffic and enable the application to have extra business capability, after the actual authorization, the application can access the platform at any time, and the platform can collect application data, so that various benefits such as data security and privacy protection are actually involved.
Because the authorization process is not disclosed, the data of the authorization process is not stored, and the authorization process does not participate in an auditor, the whole process is basically operated in a grey zone, and great difficulty is brought to responsibility tracing and right maintaining in the future. Therefore, it is urgently needed to provide a transparent, fair, traceable, auditable, automatic authorization and emergency damage-stopping application authorization scheme.
The present specification provides an application authorization scheme based on a block chain, which performs authorization and authorization on a target application through the block chain, and performs uplink chain storage and certification on the authorization and authorization process; due to the public characteristic of the blockchain, the public justice of the application authorization process can be ensured, and due to the non-falsifiable characteristic of the blockchain, the reliability of the application authorization process is ensured.
It should be noted that, in an embodiment provided in the present specification, the qualification information of the application applying for authorization is firstly linked to a chain for certification, so as to facilitate subsequent auditing.
On the other hand, the blockchain is provided with logic for application authorization suspension based on the intelligent contract, so that active suspension authorization can be supplied to the application, and the authorization can be suspended in time when the application side sends an emergency (such as risks of data security, privacy disclosure and the like), thereby protecting the benefit of the application side.
On the other hand, the blockchain is provided with an authorization charging logic based on a consensus mechanism, so that a charge bill (including a charging process and obvious charging) generated by application authorization can be calculated, the charge bill is also chained and stored, a charging result is public and transparent, and the accuracy, fairness and reliability of charging are ensured.
The blockchain described in this specification may specifically include a private chain, a common chain, a federation chain, and the like, and is not particularly limited in this specification.
For example, in one scenario, the block chain may be specifically a federation chain formed by federation members, such as an application of a third party, an authorization system, an application platform, an auditor, and a charging party; the operator of the alliance chain can deploy corresponding business by relying on the alliance chain; the authorization system, the application platform, the auditing party, the charging party, etc. as the above-described coalition members may all be a service node of the above-described service. Each service node can distribute the information related to the service generated or received by itself in the form of transaction in the alliance chain, and after the transaction is processed by the consensus of the consensus nodes in the alliance chain, the information is stored in the distributed database in the alliance chain, so as to complete the uplink certification of the transaction information.
It should be noted that the Transaction (Transaction) described in this specification refers to a piece of data created by a client of a blockchain and needs to be finally issued to a distributed database of the blockchain.
Transactions in a blockchain, generally have a narrow sense of transaction and a broad sense of transaction score. A narrowly defined transaction refers to a transfer of value issued by a user to a blockchain; for example, in a conventional bitcoin blockchain network, the transaction may be a transfer initiated by the user in the blockchain. The broad transaction refers to a piece of business data with business intention, which is issued to the blockchain by a user; for example, an operator may build a federation chain based on actual business requirements, relying on the federation chain to deploy some other types of online business (e.g., a credentialing business, etc.) unrelated to value transfer, and in such federation chain, a transaction may be a business message or business request with a business intent issued by a user in the federation chain.
The client may include any type of upper layer application that uses the bottom layer service data stored in the blockchain as a data support to implement a specific service function.
In block chain techniques, nodes in a block chain typically need to rely on a corresponding Smart contract (Smart contract) to operate on the block. Operations such as storing, modifying, deleting, etc. in a blockchain all need to rely on smart contracts. The intelligent contract may be a computer protocol intended for application to propagate, verify, or execute contracts in an informational manner that may be deployed on a blockchain. Performing the corresponding operation can be realized by declaring the business logic in the smart contract. Smart contracts allow trusted transactions to be conducted without third parties. These transactions are traceable and irreversible. Smart contracts can provide security over traditional contract methodologies and reduce other transaction costs associated with contracts. In general, the intelligent contracts can be deployed locally at the block link points, and when the nodes need to execute a certain action, the corresponding intelligent contracts can be called, and the intelligent contracts are operated to execute the service logic stated in the intelligent contracts, so that the execution result is obtained.
The application platform described in this specification may refer to a service platform that requires an authorized application. The application can acquire the service capability provided by the application platform after authorization.
The auditor can be a block chain node for performing qualification audit aiming at application parking;
the charging party may refer to a blockchain node performing authorized charging after the application termination authorization.
In some embodiments, the auditing party and the charging party may be the same node, i.e. one node may have both auditing logic and charging logic.
The embodiment of the present specification can be divided into 3 parts, which are an application enrollment contract, an application right confirmation and an application authorization, respectively.
A schematic flow chart of the application enrollment subscription and the application authorization in the blockchain is described below as shown in fig. 1.
1.1, the target application submits a parking application to an authorization system, wherein the application carries application qualification information.
The qualification information may refer to some key information of the operator corresponding to the application, for example, company information, business scope, license, approval certificate, and the like, which may indicate that the application has authorization conditions.
And 1.2, the authorization system assembles the qualification information into a resident transaction and submits the resident transaction to a block chain.
1.3, the block chain links the qualification information to the chain for certification.
The block chain can link the qualification information of the target application to a chain for certification, and the qualification information after the chain is linked cannot be tampered, so that audit is facilitated.
And 2.1, informing an auditor in the block chain to audit the qualification information.
And 2.2, receiving an audit result returned by each auditor.
Specifically, qualification audit logic declared in intelligent contracts issued on the blockchain may be invoked; wherein the qualification auditing logic is as follows:
writing a voting event in the transaction log, auditing qualification information after the auditing party of the block chain monitors the voting event, and submitting the voting transaction containing the auditing result to the intelligent contract; and the intelligent contract collects and sorts the voting transactions to obtain a final auditing result.
3. And if the audit result passes, returning successful enrollment to the authorization system.
And if the final auditing result is that the target application is successfully resident, executing the application to be resident. And can return notification of successful target application enrollment to the authorization system, which can also return successful target application enrollment.
4.1, the target application submits an authority confirmation application to the authorization system, wherein the authority confirmation application carries the authority confirmation parameters.
After receiving successful enrollment, the target application may initiate an authorization request to the authorization system, where the authorization request carries authorization parameters.
The authorization parameters may include application information, authorization validity time, necessary request parameter range limits, and the like.
And 4.2, generating an authorized intelligent contract by the authorization system, and submitting the authorized intelligent contract to the blockchain to create a transaction.
The authorization system may create an authorized intelligent contract based on the entitlement parameters in the entitlement application and initiate an authorized intelligent contract creation transaction to the blockchain.
5.1, informing an auditor in the block chain to audit the authorized intelligent contract;
after the block chain creates the authorized intelligent contract, an auditor in the block chain needs to be informed to audit the authorized intelligent contract; to ensure that the authorized intelligent contracts are intelligent contracts that meet preset requirements and can be executed in a blockchain.
And 5.2, receiving audit results returned by each auditor.
Specifically, contract auditing logic declared in intelligent contracts issued on the blockchain may be invoked; wherein the contract auditing logic is:
writing a voting event in a transaction log, auditing an authorized intelligent contract after an auditor of the block chain monitors the voting event, and submitting the voting transaction containing an auditing result to the intelligent contract; and the intelligent contract collects and sorts the voting transactions to obtain a final auditing result.
6. And returning the true right token of the target application to the authorization system.
If the final auditing result is passed, the authorized intelligent contract is in accordance with the preset condition, and can be executed in the block chain; further, a unique corresponding authenticity identifier and an authenticity token (token) may be generated for the target application. And, an entitlement token and an entitlement identification for the target application may be returned to the authorization system.
The authentication token is used for identifying the target application and is used for obtaining the calling token when the target application calls the target application platform each time.
Through the embodiment, the qualification information of the target application is chain-certified, and the qualification information passes the auditing of the auditing party in the block chain, so that the target application is added into the block chain. After the target application successfully enters the block chain, the target application can initiate an authorization application, and the authorization intelligent contract containing the authorization parameters is linked and passes through auditing, so that the authorization token of the only corresponding target application distributed by the block chain is obtained. As such, the target application may perform application authorization based on the authorization token.
A schematic flow chart of application authorization in a blockchain is described as shown in fig. 2.
1.1, the target application initiates an authorization application for acquiring the target service platform to an authorization system.
The authorization application carries an authorization token corresponding to the target application.
1.2, the authorization system submits an authorization transaction aiming at the true right token carried in the authorization application to the blockchain.
And 2.1, executing a corresponding authorization intelligent contract by the blockchain based on the authorization token to generate a calling token.
In response to the authorization transaction, invoking authorization logic (authorization smart contracts) declared in smart contracts issued in the blockchain, querying whether the confirmation tokens are stored in the blockchain; and if the confirmation token is inquired, generating the authorized call token.
2.2, the blockchain provides the call token to a target application platform and an authorization system respectively.
3. The authorization system returns the invocation token to the target application.
4. The target application calls the target application platform to execute the target service through the calling token
After receiving the call token, the target application may call the target application platform to initiate a request for executing the target service, where the request carries the call token.
5.1, the target application platform checks the calling token;
after receiving a calling token provided by the target application, the target application platform verifies the calling token; and if the verification is passed, executing the target service of the target application.
Wherein the verifying the invocation token includes:
comparing the call token provided by the target application with the call token sent by the blockchain and aiming at the target service of the target application; and if the two calling tokens are consistent, determining that the verification is passed.
And 5.2, executing the target service after the verification is passed.
And if the verification is passed, the target application platform executes the target service initiated by the target application.
6. And the target application platform stores the chain of the execution result of the target service.
After the target service is executed, the target application platform can also store the execution result in a block chain in a transaction form; the transaction carries the invocation token.
After the target service is executed, the target application platform can also return an execution result to the target application, and the call token is locally invalidated at the target application platform.
In this manner, when the target application initiates another service again based on the same invocation token, it will not execute because the invocation token has failed. In this way, the target application is prevented from repeatedly making calls based on the same call token.
7. The blockchain invalidates the call token.
After the block chain has the execution result, calling tokens carried by the transaction are used; and performing invalidation treatment on the call token in the block chain.
Through the embodiment, when the target application calls the target application platform each time, the authorized call token for each call is acquired from the block chain; and invoking the target application platform to execute the target service based on the invocation token.
A flow chart of application authorization termination and authorization accounting is presented below as shown in fig. 3.
1.1, the target application initiates a termination authorization application to an authorization system, wherein the application carries an authority confirmation token.
And 1.2, authorizing the invalidation transaction for the right token submitted by the system to the blockchain.
The authorization system receives a termination authorization request initiated by a target application, and further submits a termination authorization transaction aiming at an entitlement token carried in the termination authorization request to the blockchain so as to invalidate the entitlement token stored in the blockchain.
2.1, the blockchain links the termination authorization transaction with a chain credit;
2.2, the blockchain informs the auditor of the termination of the authorized transaction for auditing;
specifically, termination authorization audit logic declared in a smart contract issued on the blockchain may be invoked; wherein the termination authorization audit logic is:
writing a voting event in the transaction log, auditing the termination of authorized transaction after the auditing party of the block chain monitors the voting event, and submitting the voting transaction containing the auditing result to the intelligent contract; and the intelligent contract collects and sorts the voting transactions to obtain a final auditing result.
And 2.3, returning an audit result by each auditor.
The block chain may derive a final audit result based on each audit result.
3.1, block chain failure right token.
If the final auditing result is that the verification result passes, the verification token needs to be subjected to invalidation processing, namely, the block chain calls invalidation logic issued in the block chain, and the valid state of the verification token is changed into an invalidation state.
If the result of the audit is failure, the termination authorization is failed.
And 3.2, returning a termination authorization result to the authorization system by the blockchain.
