Description

Service authentication method, system and computer readable storage medium
Technical Field
The present application relates to the field of computer technologies, in particular, to the field of block chain technologies, and more particularly, to a service authentication method, system, and computer-readable storage medium.
Background
The block chain technology is a novel application technology set of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. From the data perspective, the block chain combines the data blocks in a sequential connection mode into a chain data structure according to the time sequence, and the data structure is guaranteed to be not falsifiable and not to be forged in a cryptographic mode. From a technical point of view, the blockchain technology integrates a plurality of different technologies, and by constructing a blockchain network, each node in the network is allowed to obtain a complete database copy, and updates of the blockchain-based database are maintained based on a consensus mechanism and competition calculation. Therefore, the decentralized and distrust of data storage and management are realized through an end-to-end network formed by communication of a plurality of nodes.
In a blockchain network, all operating rules and data information are public for all nodes, so each record is visible to all nodes. Meanwhile, because the nodes are distrusted, the nodes do not need to disclose identities, and each participated node is anonymous. Meanwhile, the blockchain technology has excellent security, and the modification of the database by a single node or even multiple nodes cannot affect the databases of other nodes, unless more than 51% of the nodes in the whole network can be controlled to modify simultaneously, so that the modification of the data recorded in the blockchain is possible and is almost impossible.
At present, business personnel in industries such as insurance institutions and medicines cause people to lose trust due to the fact that typical behaviors influence the trust of people in industries such as insurance and medicines for many times. Taking insurance as an example, even a very good insurance business can give up purchasing because of distrust of people to insurance business personnel, and similarly, many illegal insurance businesses are provided, benefit from the long-term induction of the insurance business personnel, forge some successful business cases, lead some old people to be doubtful, spend large price even without worrying old money, and also need to purchase. Due to the fact that the phenomena of counterfeit business information records and asymmetric information emerge endlessly, the trust of consumers on business personnel such as insurance institutions and medical representatives is seriously lost, and the rights and interests of the two parties are further damaged.

Fig. 1 is a schematic diagram of a service authentication system according to an embodiment of the present application. As shown in fig. 1, the service authentication system includes a first node 1, a second node 2, a third node 3, and a service platform node 4. The first node 1 is a node where business personnel (such as medicine, insurance and other business personnel) are located, the second node 2 is a node where consumers are located, and the third node 3 is a digital identity establishment organ node (also called a public security department). The first node 1, the second node 2, the third node 3 and the service platform node 4 may all be connected to a blockchain network, and perform connection communication through blockchains.
In a network based on the blockchain technology, a general data processing device loaded with a predetermined program can freely enter the network to become one of blockchain nodes. When entering the network, each node randomly obtains a private key. The private key can obtain a corresponding public key through mathematical operation, the public key can obtain a network address corresponding to the node through a series of hash operation, and the derivation process is irreversible in theory. The public key of the block chain node and the network address corresponding to the block chain link point can be externally disclosed, and therefore, the public key and the network address can be used as the identification of the block chain link point. The network address of the node in the blockchain network is used as the unique identifier of the node.
In the embodiment of the present application, the third node 3 (i.e., the node of the digital identity establishment authority) is configured to acquire the biological characteristics of the service person corresponding to the first node 1 (i.e., the node where the service person is located), and generate an identity token according to the biological characteristics of the service person, where the identity token includes a hash value of the biological characteristics of the service person. The biological characteristics are information of the business personnel after data processing of the specific characteristic points of at least one biological characteristic of the business personnel in a preset number. The biological characteristics can be one or more characteristics of information such as iris, DNA, electrocardiogram, retina, brain wave, infrared thermogram, vein, etc.
The third node 3 is further configured to perform a blockchain based identity token transaction with the first node 1 generating a third transaction sheet. Wherein the third transaction ticket comprises a private key signature of the third node 3, an identity token of the first node and an address of the first node 1.
After the first node 1 and the third node 3 perform the identity token transaction based on the blockchain, the third transaction sheet is broadcast in the blockchain. And other nodes in the block chain use the public key of the third node 3 to verify the third transaction list, and after the verification is passed, the digital identity of the business personnel corresponding to the first node 1 is successfully established. The first node 1 obtains the identity token of the service personnel corresponding to the first node 1.
In the embodiment of the application, the establishment of the digital identity of the service personnel is completed through the identity token transaction based on the block chain, so that the identity information of the service personnel is not concentrated in a central database any more, and the safety problems of data leakage, identity counterfeiting and the like can be effectively prevented.
The first node 1 is configured to perform a blockchain based identity token transaction with the second node 2 (i.e. the node where the consumer is located) to generate a second transaction order. Wherein the second transaction ticket comprises a private key signature of the first node 1, an identity token of the first node and an address of the second node 2.
After the first node 1 and the second node 2 perform the identity token transaction based on the blockchain, the second transaction sheet is broadcast in the blockchain. And other nodes in the block chain verify the second transaction list by using the public key of the first node 1, and if the second transaction list passes the verification, the digital identity authentication of the service personnel corresponding to the first node 1 is successful. The second node 2 obtains the identity token of the first node 1.
In the embodiment of the application, the identification of the digital identity of the service personnel is completed through the identity token transaction based on the block chain, so that the service personnel can conveniently and efficiently self-authenticate the identity.
The second node 2 is configured to initiate a block chain based identity token transaction to the service platform node 4 to generate a first transaction order, where the first transaction order includes a private key signature of the second node 2, an identity token of the first node 2, and an address of the service platform node 4.
After the second node 2 and the service platform node 4 execute the identity token transaction based on the block chain, the first transaction sheet is broadcast in the block chain. And other nodes in the block chain use the public key of the second node 2 to verify the first transaction list, and when the first transaction list passes the verification, the service platform node 4 acquires the identity token of the first node 1.
The service platform node 4 is configured to query the service staff information corresponding to the first node 1 according to the identity token of the service staff corresponding to the first node 1 after the first transaction list is verified and a request for acquiring the service staff information from the second node 2 is received, and return a query result. Wherein, the request for obtaining the service personnel information comprises the address of the first node 1. The service personnel information includes service information records and credit records. The service information record includes the service type (e.g. insurance type, medicine type, etc.) and the address of the first node 1. The service platform node 4 evaluates the credit record of the service personnel by counting and calculating the service information record corresponding to the service personnel.
It should be understood that the second node 2 may send a request for obtaining the service personnel information to the service platform node after the first transaction order is verified; or send a request for acquiring the service personnel information to the service platform node while initiating the identity token transaction based on the block chain to the service platform node 4.
Preferably, after the identity token is used to log in the service platform node 4 to inquire the service personnel information, the identity token is set to be invalid to maintain the safety of the service personnel information.
After the second node 2 obtains the identity token of the first node 1, the identity token of the first node 1 may be forwarded to other consumer nodes by a blockchain based identity token transaction. However, after the identity token of the first node 1 is sent to the service platform node 4 and the service personnel information inquiry is made, the identity token is destroyed and disabled at the service platform node 4. That is, only one query can be made per identity token.
Preferably, each service information record completed by the service person corresponding to the first node 1 is uploaded to the service platform node 4, and the hash value of each service information record of the service person is linked and stored.
Further, the second node 2 compares the obtained hash value of the business information record of the business personnel corresponding to the first node 1 with the evidence storage record of the first node 1 on the blockchain. And if the hash value of the acquired service information record is consistent with the evidence storing record on the corresponding block chain, inquiring the acquired service personnel information at the service platform node to be real. If the hash value of the obtained service information record is inconsistent with the corresponding certificate storing record on the block chain, the service personnel information obtained by inquiring the service platform node may have a forgery phenomenon.
In summary, in the embodiment of the present application, the digital identity of the service personnel is established through the identity token transaction based on the block chain, so that the identity information of the service personnel is no longer concentrated in the central database, and security problems such as data leakage and identity forgery can be effectively prevented. And the identification of the digital identity of the service personnel is completed through the identity token transaction based on the block chain, so that the service personnel can more conveniently and efficiently self-authenticate the identity. By inquiring the service personnel information through the identity token transaction based on the block chain, the consumer can more accurately inquire the service information of the service personnel and verify the authenticity of the service information of the service personnel in the block chain, so that the interference of false information is avoided, and the optimal consumption scheme is selected.
Fig. 2 is a flowchart of a service authentication method according to an embodiment of the present application. As shown in fig. 2, in step S110, the third node (i.e., the node of the digital identity authority) acquires the biometric feature of the service person corresponding to the first node, and generates an identity token according to the biometric feature of the service person, where the identity token includes a hash value of the biometric feature of the service person. The biological characteristics are information of the business personnel after data processing of the specific characteristic points of at least one biological characteristic of the business personnel in a preset number. The biological characteristics can be one or more characteristics of information such as iris, DNA, electrocardiogram, retina, brain wave, infrared thermogram, vein, etc.
In step S120, the third node performs identity token transaction based on the block chain with the first node to generate a third transaction sheet. The third transaction ticket includes a private key signature of the third node, an identity token of the first node, and an address of the first node.
In step S130, the third transaction order is broadcast in the blockchain, and other nodes in the blockchain verify the third transaction order according to the public key of the third node. And if the third transaction sheet passes the verification, the digital identity of the service personnel corresponding to the first node is successfully established. And the first node acquires the identity token.
In step S140, the first node (the node where the service person is located) and the second node (the node where the consumer is located) perform identity token transaction based on the blockchain to generate a second transaction order. The second transaction ticket includes a private key signature of the first node, an identity token of the first node, and an address of the second node.
In step S150, the second transaction order is broadcast in the blockchain, and other nodes in the blockchain verify the second transaction order according to the public key of the first node. And if the second transaction sheet is verified, the digital identity authentication of the service personnel corresponding to the first node is successful. The second node obtains the identity token of the first node. And if the second transaction list is not verified, the digital identity authentication of the service personnel corresponding to the second node fails. That is, the service person may forge the information.
In step S160, the second node and the service platform node execute the identity token transaction based on the block chain to generate a first transaction order, where the first transaction order includes a private key signature of the second node, an identity token of the first node, and an address of the service platform node.
In step S170, the first transaction order is broadcast in the blockchain, and other nodes in the blockchain verify the first transaction order according to the public key of the second node. And when the first transaction sheet is verified, the service platform node acquires the identity token of the first node.
In step S180, the second node sends a request for obtaining the service staff information to the service platform node. The request for acquiring the service personnel information comprises the address of the first node.
In step S190, the service platform node queries the service staff information corresponding to the first node according to the identity token of the first node, and returns a query result. The service personnel information comprises a service information record and a credit record. The service information record includes a service type (e.g., insurance type, medicine type, etc.) and an address of the first node. And the service platform node evaluates the credit record of the service personnel by counting and calculating the service information record corresponding to the service personnel.
It should be understood that the second node may also send a request for obtaining the service personnel information to the service platform node while initiating the identity token transaction based on the block chain to the service platform node.
Preferably, after the identity token is used for logging in the service platform node to inquire the service personnel information, the identity token is set to be invalid so as to maintain the safety of the service personnel information.
After the second node obtains the identity token of the first node, the identity token of the first node may be forwarded to other consumer nodes through blockchain-based identity token transactions. However, after the identity token of the first node is sent to the service platform node and the service personnel information inquiry is carried out, the identity token is destroyed and disabled at the service platform node. That is, only one query can be made per identity token.
In the embodiment of the application, the digital identity of the service personnel is established through the identity token transaction based on the block chain, so that the identity information of the service personnel is not concentrated in a central database any more, and the safety problems of data leakage, identity counterfeiting and the like can be effectively prevented. And the identification of the digital identity of the service personnel is completed through the identity token transaction based on the block chain, so that the service personnel can more conveniently and efficiently self-authenticate the identity. By inquiring the information of the service personnel through the identity token transaction based on the block chain, the consumer can inquire the service information of the service personnel more accurately, the interference of false information is avoided, and therefore the optimal consumption scheme is selected.
Preferably, the service authentication method further includes step S1a 0. In step S1a0, each service information record completed by the service person corresponding to the first node is uploaded to the service platform node, and the hash value of each service information record of the service person is linked to store a certificate.
Preferably, the service authentication method further includes step S1B 0. In step S1B0, the second node compares the obtained hash value of the business information record of the business person corresponding to the first node with the evidence storage record of the first node on the blockchain. And if the hash value of the acquired service information record is consistent with the evidence storing record on the corresponding block chain, inquiring the acquired service personnel information at the service platform node to be real. If the hash value of the obtained service information record is inconsistent with the corresponding certificate storing record on the block chain, the service personnel information obtained by inquiring the service platform node may have a forgery phenomenon.
Fig. 3 is a flowchart of a method of establishing a digital identity according to an embodiment of the present application. As shown in fig. 3, in step S100, the third node (i.e., the node of the digital identity establishment authority) acquires the biological characteristics of the service personnel corresponding to the first node (i.e., the node where the service personnel is located), and generates an identity token according to the biological characteristics of the service personnel, where the identity token includes a hash value of the biological characteristics of the service personnel. The biological characteristics are information of the business personnel after data processing of the specific characteristic points of at least one biological characteristic of the business personnel in a preset number. The biological characteristics can be one or more characteristics of information such as iris, DNA, electrocardiogram, retina, brain wave, infrared thermogram, vein, etc.
In step S200, the third node performs identity token transaction based on the block chain with the first node to generate a third transaction sheet. The third transaction ticket includes a private key signature of the third node, an identity token of the first node, and an address of the first node.
In step S300, the third transaction order is broadcast in the blockchain, and other nodes in the blockchain verify the third transaction order according to the public key of the third node. And if the third transaction sheet passes the verification, the digital identity of the service personnel corresponding to the first node is successfully established.

As shown in fig. 4, in step S400, the second node (i.e., the node where the consumer is located) performs a block chain-based identity token transaction with the first node (i.e., the node where the service person is located) to authenticate the digital identity of the service person corresponding to the first node, and obtains the identity token of the first node.
In step S500, the second node and the service platform node execute an identity token transaction based on the block chain to generate a first transaction order, where the first transaction order includes a private key signature of the second node, an identity token of the first node, and an address of the service platform node.
The first transaction order is broadcast in the blockchain, and other nodes in the blockchain verify the first transaction order according to the public key of the second node. And if the first transaction sheet is verified, the service platform node acquires the identity token of the first node.
In step S600, the second node sends a request for obtaining information of service personnel to the service platform node. The request for acquiring the service personnel information comprises the address of the first node.
In step S700, the service platform node queries the service staff information corresponding to the first node according to the identity token of the service staff corresponding to the first node, and returns a query result. The service personnel information comprises a service information record and a credit record. The service information record includes a service type (e.g., insurance type, medicine type, etc.) and an address of the first node. And the service platform node evaluates the credit record of the service personnel by counting and calculating the service information record corresponding to the service personnel.
It should be understood that the second node may also send a request for obtaining the service personnel information to the service platform node while initiating the identity token transaction based on the block chain to the service platform node.
Preferably, after the identity token is used for logging in the service platform node to inquire the service personnel information, the identity token is set to be invalid so as to maintain the safety of the service personnel information.
After the second node obtains the identity token of the first node, the identity token of the first node may be forwarded to other consumer nodes through blockchain-based identity token transactions. However, after the identity token of the first node is sent to the service platform node and the service personnel information inquiry is carried out, the identity token is destroyed and disabled at the service platform node. That is, only one query can be made per identity token.
Further, the method for querying service information further includes step 800. In step 800, each service information record completed by the service person corresponding to the first node is uploaded to the service platform node, and meanwhile, the hash value of each service information record of the service person is linked to store a certificate.
Further, the method for querying service information further includes step 900. In step 900, the second node compares the obtained hash value of the service information record of the service person corresponding to the first node with the evidence storage record of the first node on the block chain. And if the hash value of the acquired service information record is consistent with the evidence storing record on the corresponding block chain, inquiring the acquired service personnel information at the service platform node to be real. And if the hash value of the acquired business information record is inconsistent with the evidence storing record on the corresponding block chain, the business personnel information inquired and acquired by the business platform node has a forgery phenomenon.
The step S400 further includes steps S410 to S430. As shown in fig. 5, in step S410, the second node (the node where the consumer is located) performs the identity token transaction based on the block chain with the first node (the node where the service staff is located) to generate a second transaction order. The second transaction ticket includes a private key signature of the first node, an identity token, and an address of the second node.
In step S420, the second transaction order is broadcast in the blockchain, and other nodes in the blockchain verify the second transaction order according to the public key of the first node. And if the second transaction sheet passes the verification, the digital identity authentication of the service personnel corresponding to the first node is successful. And if the second transaction list is not verified, the digital identity authentication of the service personnel corresponding to the second node fails.
In step S430, the second node obtains the identity token of the service person corresponding to the first node.
The digital identity authentication method in the embodiment of the application finishes the authentication of the digital identity of the service personnel through the identity token transaction based on the block chain, so that the service personnel can more conveniently and efficiently self-authenticate the identity, and the information of the service personnel is inquired through the identity token transaction based on the block chain, so that a consumer can more accurately inquire the service information of the service personnel, the interference of false information is avoided, and an optimal consumption scheme is selected.
