The DApp can require the user to authorize the inquiry authority of the credit points, apply authorization to the credit management node, if the credit points meet the preset requirement of the DApp, the authorization success information is returned, and the user can use the DApp. The credit management node can also record the credit point change condition of the user through the block chain, and provide credit authorization service for the DApp.
The embodiments of the present application will be described below with reference to the drawings.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a data processing permission verification method according to an embodiment of the present application, where the method may be applied to a credit management node. The method can comprise the following steps:
201. the credit management node receives an authorization request, wherein the authorization request comprises a credit point threshold value, a user identification, an identification of a distributed application program, a user account number of a user in the distributed application program, and a digital signature of a user node.
The credit management node in the embodiment of the application can be any third-party platform, and supervises and manages information such as credit points of the user. In one embodiment, the credit management node is specifically a server. The credit management node may also pre-join the blockchain network.
The authorization request is sent by the user side, and may be triggered when the user side registers or logs in the DApp through the user account. When detecting that the user side logs in the DApp, the DApp background management end can generate a credit inquiry instruction and send the credit inquiry instruction to the user side if the user side does not perform credit authorization, requests the user side to authorize the credit condition for verification, can acquire a user identifier corresponding to the credit management node of the user at the user side, and generates the authorization request to send to the credit management node.
For example, after the user logs in the DApp using account a (user account), part of the functions may be disabled because the DApp cannot be normally used temporarily without credit authorization. A prompt box can be displayed on the interface of the DApp to indicate that the DApp needs to acquire the credit information of the user on the third-party platform B and request the authorization of the user. And if the user clicks and determines, automatically acquiring a user account (user identification) of the user on the third-party platform B, sending an authorization request to the third-party platform B, and acquiring and inquiring whether the credit score of the user account meets the use standard of the DApp.
The identifier of the distributed application program is an identifier of a DApp to be logged in and operated by the user, and the user account may be an account used by the user to log in the DApp. The credit integration threshold may be preset by the DApp developer. The DApp runs under the support of the blockchain, and running operation logic of the DApp is specified by means of an intelligent contract and is deployed on the blockchain. The credit integration threshold may also be predefined in the associated smart contract.
202. And acquiring the public key of the user node from the block chain, and verifying the digital signature by using the public key.
Specifically, the credit management node may first verify the received authorization request to determine the authenticity of the operation instruction. In a distributed network of a block chain, communication among nodes and trust achievement can depend on a digital signature technology, and digital signatures relate to tools such as public keys, private keys, wallets and the like, and have two functions: firstly, the message is proved to be actually signed and sent out by the message sender; the second is to determine the integrity of the message.
The digital signature technique is to encrypt the digest information with the sender's private key and transmit it to the receiver together with the original text. The receiver can decrypt the encrypted digest information only with the sender's public key, and then generates a digest information for the received original text using a HASH (HASH) function, which is compared with the decrypted digest information. If the information is the same as the received information, the received information is complete and is not modified in the transmission process, otherwise, the information is modified. The digital signature is able to verify the integrity of the information.
Similarly, the authorization request may include a digital signature of the user node. In order to verify whether the authorization request is sent by the corresponding user node, the public key of the user node may be obtained from the blockchain, and then the public key is used to resolve the authorization request.
Specifically, a cipher text corresponding to the authorization request can be decrypted by using a private key of the user, and an abstract is obtained through hash operation; and then acquiring a public key corresponding to the user node, analyzing the corresponding digital signature to obtain an abstract, comparing the abstract of the decrypted ciphertext with the abstract of the decrypted digital signature respectively, and if the abstracts are consistent, determining that the authorization request is matched with the user node, so that the authorization request can be determined to come from the user node, the authorization request is real and effective, and the authorization request can be processed.
If the abstracts are not completely consistent, the authorization request is determined to be not matched with the user node, the authorization request is determined not to be generated by the user node, the subsequent steps can not be executed, the security of using the DApp by the user is improved, and information is prevented from being stolen.
203. If the verification is successful, establishing an authorization processing item of the authorization request, and distributing a serial number to the authorization processing item.
If the authentication is successful, the authorization request can be confirmed to come from the user node, and the authorization request is true and effective, so that corresponding authorization processing items can be established, and a unique serial number is allocated for processing.
In an alternative embodiment, after step 203, the method further comprises:
and generating verification information, signing the verification information by using a private key of the credit management node, and uploading the verification information to the block chain, wherein the verification information indicates that the distributed application program has the inquiry authority of credit points corresponding to the user account.
Optionally, verification information may be generated in the blockchain, and the verification information is signed by using a private key of the credit management node and then uploaded to the blockchain, so as to indicate that the DApp has a query right for credit points corresponding to a user account, and complete authorization, where the user account may be associated with a user identifier of the user at the credit management node, and then the DApp may obtain the credit point information of the user through the credit management node.
Further optionally, when the distributed application program has an inquiry authority for credit points corresponding to the user identifier, the method further includes:
and periodically acquiring credit points corresponding to the user account, and recording the acquired credit points corresponding to the user account in a block corresponding to the distributed application program.
Specifically, under the condition that the credit management node authorizes the DApp to access the credit score of a certain user, the DApp background management end may request the credit management node to acquire the credit score of the user account when needed, specifically, the block chain stores the user account and the user identifier of the user at the credit management node, and the credit score of the user identifier may be periodically acquired from the credit management node according to a preset period of the intelligent contract, so as to determine whether the user account meets the use requirement of the DApp. The credit point change condition is recorded through the block chain, the credit point change condition cannot be tampered, and the query content is reserved, so that the data can be traced.
204. And acquiring a credit score corresponding to the user identifier, and judging whether the credit score corresponding to the user identifier is greater than or equal to the credit score threshold value.
Specifically, the credit management node may determine the credit point of the user according to a given credit point threshold. Other functions can be supported in the third-party application program corresponding to the credit management node, such as functions of a social application or a payment application; the credit management node stores credit points of a plurality of users, manages the credit points by user identifiers, and can run an autonomous point change logic at the credit management node to measure and update the credit points of each user, which is not limited herein.
The credit management node may obtain a credit score corresponding to the user identifier, and then determine whether the credit score corresponding to the user identifier is greater than or equal to the credit score threshold, if so, step 205 may be executed; if not, go to step 207.
205. And if the credit integral corresponding to the user identification is greater than or equal to the credit integral threshold, generating an authorization certificate and authorization success information of the authorization processing item, generating a target block in a block chain according to the identification of the distributed application program, and storing the authorization certificate, wherein the authorization certificate comprises the identification of the distributed application program, a user account number of the user in the distributed application program, an authorization timestamp and a serial number of the authorization processing item, and the authorization certificate is digitally signed by using a private key of the credit management node.
206. And feeding back the successful authorization information to a user side through the distributed application program to indicate that the user account has the authority of using the distributed application program.
When the credit point corresponding to the user identification is inquired to be larger than or equal to the credit point threshold value, the credit condition of the user meets the requirement of DApp, the credit management node acquires the user account number, the user identification, the identification of the DApp, the authorization timestamp and the serial number of the authorization processing item, uses a private key signature to acquire the authorization voucher, and stores the authorization voucher in a block chain, and the DApp background management end opens the normal use permission of the user account number. And determining a stored target block or generating a corresponding target block according to the identifier of the distributed application program in the block chain, and storing the authorization certificate.
Meanwhile, authorization success information can be generated and fed back to the user side through the distributed application program. The user end can receive the fed-back authorization success information through the DApp, so that the user account of the user end can normally use the DApp.
207. And if the credit point corresponding to the user identification is smaller than the credit point threshold value, generating authorization failure information, and feeding the authorization failure information back to the user side through the distributed application program to indicate that the user account does not have the authority of using the distributed application program.
When the credit point corresponding to the user identifier is smaller than the credit point threshold value, the credit of the user is low and does not meet the requirement of the DApp, the credit management node can also acquire the user account number, the user identifier and the DApp identifier to generate authorization failure information, and the DApp background management end prohibits the normal use of the user account number. The user end can receive the fed back authorization failure information through the DApp, and cannot operate at the DApp through the user account.
In one embodiment, the blockchain underlying platform may include processing modules for user management, basic services, intelligent contracts, and operation monitoring. Wherein, the user management module can be undertaken by the supervisory node with part or all of the functions: the system is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, DApp operation and operation conditions of certain real identity nodes are supervised and audited, and rule configuration (wind control audit) of risk control is provided; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the service request to storage after consensus on the valid request is completed, for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, transmits the service information to a shared account (network communication) completely and consistently after encryption, and performs recording and storage; the intelligent contract module is responsible for registering and issuing contracts, triggering contracts and executing contracts, such as intelligent contracts of DApp in the application, developers can define contract logic through a certain programming language, issue the contract logic to a block chain (contract registration), call keys or other event triggering execution according to the logic of contract terms, complete the contract logic, and simultaneously provide the function of canceling contract upgrading logout; the operation monitoring module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation in the product release process and visual output of real-time states in product operation, such as: alarm, monitoring network conditions, monitoring node equipment health status, and the like.
