Description

Service authentication method, system and computer readable storage medium
Technical Field
The present application relates to the field of computer technology, and in particular, to the field of blockchain technology, and more particularly, to a service authentication method, system, and computer readable storage medium.
Background
Blockchain technology is a novel set of application technologies for computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and the like. From a data perspective, a blockchain combines data blocks in a sequential manner in time order into a chained data structure that is cryptographically secured against tampering and counterfeiting. From a technical perspective, blockchain technology integrates a number of different technologies by building a blockchain network such that each node within the network is allowed to obtain a complete database copy and maintain updates to the blockchain-based database based on consensus mechanisms and competing computations. Therefore, the data storage and management are decentralised and the signaling is removed through an end-to-end network formed by communication of a plurality of nodes.
In a blockchain network, all operational rules and data information are disclosed for all nodes, and therefore, each record is visible to all nodes. Meanwhile, since the nodes are de-trusted, the identity between the nodes does not need to be disclosed, and each participating node is anonymous. At the same time, blockchain technology has excellent security, and modification of databases by single or even multiple nodes cannot affect databases of other nodes, and modification of blockchain-recorded data is not possible unless more than 51% of nodes in the entire network can be controlled to be modified simultaneously, which is almost impossible.
At present, business personnel in industries such as insurance institutions, medicines and the like have a plurality of influence on trust of people in industries such as insurance, medicines and the like due to typical behaviors, so that people have a lack of trust. Taking insurance as an example, even very excellent insurance service can be abandoned for purchase because people are not trusted by insurance service personnel, and likewise, a plurality of irregular insurance services exist, and due to long-term induction of the insurance service personnel, some successful service cases are forged, so that some old people are deeply convinced, and the old people can purchase the insurance service at high cost even without losing the old people.

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 the like) are located, the second node 2 is a node where consumers are located, and the third node 3 is a digital identity establishment authority node (namely 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, with connection communication through the blockchain. It should be appreciated that in a blockchain technology based network, a generic data processing device loaded with a pre-program may freely enter the network as one of the blockchain nodes.
In this embodiment of the present application, the third node 3 (i.e. the node of the digital identity establishment authority) is configured to collect 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 the private key of the first node 1 according to the biological characteristics of the service person. Wherein the private key of the first node 1 is calculated according to a biometric key generation algorithm based on the chaotic system.
The chaotic system is characterized in that a seemingly random irregular motion exists in a deterministic system, and the behavior of the chaotic system is shown as uncertainty, unrepeatable and unpredictable, namely a chaotic phenomenon. Chaos is an inherent characteristic of nonlinear power systems, and is a phenomenon common to nonlinear systems. The chaotic system has both the sensitivity and randomness characteristics necessary for generating the key, so the private key of the first node 1 can be calculated according to a biometric key generation algorithm based on the chaotic system.
For example, assume that the biometric characteristic of the business person corresponding to the first node 1 is located in a series of intervals [0,1 ]]Floating point number (c) 1 ,c 2 ,…，c L ) The identification, the step of generating the private key using a biological feature processing function based on TD-ERCS (tangent delay-ellipse cavity map system), a type of chaotic system, is as follows:
(1) Initializing a key: setting the X-axis of the starting point of the ray 0 And an angle α, a cut delay m (to compensate for performance degradation caused by discretization, the reflection tangent takes an elliptical tangent of the first m reflection points, called the cut delay m) and an elliptical parameter μ;
(2) Normal state iteration: setting the slope K of the tangent line n Equal to biological feature c i (the biological characteristics are input in the order of first and then in the reverse order), and 2L iterations are carried out on the system;
(3) Final iteration: setting the cutting delay as m, and carrying out the last 38 iterations on the system;
(4) Generating a private key: extract the abscissa x in the last 32 iterations n Is to set up a 256-bit private key.
The iterative formula is as follows:
Figure BDA0001533675200000061
Figure BDA0001533675200000062
Figure BDA0001533675200000063
wherein x is n ，y n ，k n Respectively representing the abscissa and the ordinate of the nth reflection point and the slope of the reflection line; k (K) n The tangential slope of the nth reflection point is shown.
It should be appreciated that the above example is only one of the algorithms for calculating the private key from the biometric feature based on the chaotic system, and that other available algorithms may be used to calculate the private key from the biometric feature.
The public key of a blockchain node is information generated by subjecting its private key to an elliptic curve encryption algorithm. The security of elliptic curve cryptography algorithms is based on the difficulty of discrete logarithms on elliptic curves.
Elliptic curve is formed by a wilt tesla equation with two arguments x and y:
y 2 +axy+by＝x 3 +cx 2 +dx+e
the set of all points (x, y) determined is added with an infinity point O infinity (considered as its y coordinate infinity).
Elliptic curves commonly used in cryptographic systems are defined over a finite field Fp, i.e. a discrete elliptic curve equation:
y 2 ＝x 3 +ax 2 +b(mod p)
the set of all points (x, y) determined is added with an infinity point O infinity. Wherein x, y, a, b are all values on the finite field Fp, and a, b satisfies 4a 3 +27b 2 Not equal to 0, p is a prime number greater than 3, and Ep (a, b) is typically used to represent such curves.
At a certain point P on the elliptic curve, there is a minimum number n, such that np=o++then n is the order of the point P.
Provided K, G is a point on Ep (a, b), and k=kg, K is an integer less than n (n is the order of point G). Given K and G, K is easy to calculate according to the addition method, but given K and G, K is difficult to solve, and no effective method has been available to solve this problem until now, which is the principle of the elliptic encryption algorithm (the addition method includes g+g=2g, that is, kG is K G additions).
The point G is a base point selected by the user on the elliptic curve Ep (a, b). K is the private key selected by the user (K < n, n is the order of the base point G), and K is the public key calculated from the private key K.
In this embodiment, the private key of the first node 1 is obtained by the biometric feature of the service personnel through a biometric key generation algorithm based on the chaotic system, and then the third node 3 selects a corresponding elliptic curve and a base point to calculate the public key of the first node 1. The public key of the first node 1 may be used to derive the address of the first node 1 by a series of hash operations, and this derivation is theoretically irreversible. It should be appreciated that the public key of a blockchain node and the address corresponding to the blockchain node may be externally disclosed and thus may be used as an identification of the blockchain node. The embodiments of the present application use the address of a node in a blockchain network as its unique identification.
It should be appreciated that the collected biometric is data processed information of a predetermined number of distinct feature points of at least one biometric of the business person. The biological characteristics can be one or more characteristics of iris, DNA, electrocardiogram, retina, brain wave, infrared temperature spectrogram, vein and other information.
The third node 3 (i.e. the digital identity establishment authority node) is further configured to initiate a blockchain based identity token transaction to the first node 1 (i.e. the node where the business person is located) to generate a third transaction ticket. The third transaction ticket comprises the private key signature of the third node 3, the identity token of the first node 1 and the address of the first node 1. Wherein the identity token comprises an identification of predetermined query service personnel information. The identification of the predetermined inquiry service personnel information may be a hash value of the identity feature of the service personnel corresponding to the first node 1 or other information related to the identity information of the service personnel.
After the first node 1 and the third node 3 perform the blockchain transaction, the third transaction ticket is broadcast in the blockchain. And the other nodes in the blockchain verify the third transaction list by using the public key of the third node 3, and if the third transaction list is verified, the digital identity of the business personnel corresponding to the first node 1 is successfully established. The first node 1 obtains an identity token of the first node 1.
In the embodiment of the application, the establishment of the digital identity of the business personnel is completed through the identity token transaction based on the blockchain, so that the identity information of the business personnel is not concentrated in a central database any more, and the safety problems of data leakage, identity forging and the like can be effectively prevented.
The first node 1 is configured to initiate a blockchain-based identity token transaction to the second node 2 (i.e. the node where the consumer is located) to generate a first transaction ticket. Wherein the first transaction ticket comprises the private key signature of the first node 1, the identity token of the first node 1 and the address of the second node 2.
After the first node 1 and the second node 2 conduct the blockchain transaction, the first transaction ticket is broadcast in the blockchain. And the other nodes in the blockchain verify the first transaction list by using the public key of the first node 1, and if the first transaction list is verified, the digital identity authentication of the business 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 business personnel is completed through the identity token transaction based on the blockchain, so that the business personnel can more conveniently and efficiently self-verify the identity.
The second node 2 is configured to initiate a blockchain based identity token transaction to the service platform node 4 to generate a second transaction ticket comprising the private key signature of the second node 2, the identity token of the first node 1 and the address of the service platform node 4.
After the second node 2 performs a blockchain-based identity token transaction with the service platform node 4, the second transaction ticket is broadcast in the blockchain. The other nodes in the blockchain verify the second transaction ticket using the public key of the second node 2. When the second transaction order is verified, the service platform node 4 obtains the identity token of the first node 1. The identity token includes an identification of predetermined query service personnel information.
The service platform node 4 is configured to query the service personnel information corresponding to the first node 1 according to the identifier of the query service personnel information in the identity token after the second transaction order is verified and the service platform node receives the request of the second node for acquiring the service personnel information, and returns a query result. Wherein the business person information includes business information records and credit records. The service information record comprises a service type (e.g. insurance type, medical type, etc.) and an address of the first node 1. The service platform node 4 evaluates the credit record of the service person by statistically calculating the corresponding service information record of the service person.
It should be appreciated that the second node 2 may send a request to the service platform node to obtain service personnel information after the second transaction ticket is verified; a request to obtain service personnel information may also be sent to the service platform node while initiating a blockchain based identity token transaction to the service platform node 4.
Preferably, after the identity token is used to log in to the service platform node 4 to query the service personnel information, this identity token is set to fail to maintain the security 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 blockchain based identity token transactions. However, after the identity token of the first node 1 is sent to the service platform node 4 and the service personnel information query is made, the identity token is destroyed and invalidated at the service platform node 4. That is, each identity token can only be queried once.
Preferably, each service information record completed by the service personnel 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 personnel is entered into the chain for verification.
Further, the second node 2 compares the obtained hash value of the service information record of the service personnel corresponding to the first node 1 with the certificate record of the first node 1 on the blockchain. If the hash value of the acquired service information record is consistent with the certificate record on the corresponding block chain, the service personnel information acquired by inquiring at the service platform node is true. If the hash value of the acquired service information record is inconsistent with the certificate record on the corresponding blockchain, the service personnel information acquired by inquiring in the service platform node may be forged.
In summary, in the embodiment of the present application, the digital identity of the service personnel is established through the blockchain-based identity token transaction, so that the identity information of the service personnel is not concentrated in the central database any more, and the security problems such as data leakage and identity forging can be effectively prevented. And the identification of the digital identity of the business personnel is completed through the identity token transaction based on the blockchain, so that the business personnel can more conveniently and efficiently self-verify the identity. By querying the business personnel information based on the identity token transaction of the blockchain, a consumer can more accurately query the business information of the business personnel and verify the authenticity of the business information of the business personnel in the blockchain, 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 digital identity establishment authority node) collects the biometric characteristics of the business person corresponding to the first node (i.e., the node where the business person is located) to generate the private key of the first node. The private key of the first node is calculated according to a biological characteristic key generation algorithm based on the chaotic system. The private key of the first node is subjected to an elliptic curve cryptography algorithm to generate a public key of the first node. The public key of the first node obtains the address of the first node through a series of hash operations. The collected biological characteristics are information of the preset number of clear characteristic points of at least one biological characteristic of the business personnel after data processing. The biological characteristics can be one or more characteristics of iris, DNA, electrocardiogram, retina, brain wave, infrared temperature spectrogram, vein and other information.
In step S120, the third node performs a blockchain-based identity token transaction with the first node to generate a third transaction ticket. 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 based on the public key of the third node. If the third trade bill passes the verification, the digital identity of the service personnel corresponding to the first node is successfully established. The first node obtains the identity token.
In step S140, a first node (a node where business personnel are located) performs a blockchain-based identity token transaction with a second node (a node where consumers are located) to generate a first transaction ticket. The first 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 first transaction order is broadcast in the blockchain, and other nodes in the blockchain verify the first transaction order based on the public key of the first node. If the first transaction list passes the verification, the digital identity authentication of the service personnel corresponding to the first node is successful, and the second node acquires the identity token of the first node. If the first transaction order fails verification, the digital identity authentication of the service personnel corresponding to the second node fails. That is, the business person may falsify the information.
In step S160, the second node initiates a blockchain-based identity token transaction to the service platform node to generate a second transaction ticket, the second transaction ticket including a private key signature of the second node, an identity token of the first node, and an address of the service platform node. The identity token includes an identification of predetermined query traffic personnel information.
In step S170, the second transaction order is broadcast in the blockchain, and other nodes in the blockchain verify the second transaction order based on the public key of the second node. And when the second transaction order is verified, the service platform node acquires the identity token of the first node.
In step S180, the second node sends a request for acquiring service personnel information to the service platform node. Wherein the request for obtaining service personnel information includes an address of the first node.
In step S190, the service platform node queries the service personnel information corresponding to the first node according to the identifier of the query service personnel information in the identity token of the first node, and returns the query result. Wherein the business person information includes business information records and credit records. The service information record includes a service type (e.g., insurance type, medical type, etc.) and an address of the first node. The service platform node evaluates the credit record of the service personnel by counting the corresponding service information record of the service personnel.
It should be appreciated that the second node may also send a request to the service platform node to obtain service personnel information while initiating a blockchain-based identity token transaction to the service platform node.
Preferably, after the identity token is used to log in to the service platform node to query the service personnel information, the identity token is set to fail to maintain the security 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 via 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 query is made, the identity token is destroyed and invalidated at the service platform node. That is, each identity token can only be queried once.
In the embodiment of the application, the digital identity of the business personnel is established through the identity token transaction based on the blockchain, so that the identity information of the business personnel is not concentrated in the central database any more, and the safety problems of data leakage, identity forging and the like can be effectively prevented. And the identification of the digital identity of the business personnel is completed through the identity token transaction based on the blockchain, so that the business personnel can more conveniently and efficiently self-verify the identity. By querying business personnel information based on the identity token transaction of the blockchain, a consumer can more accurately query the business information of the business personnel, and the interference of false information is avoided, so that the optimal consumption scheme is selected.
Preferably, the service authentication method further includes step S1A0. In step S1A0, each service information record completed by the service personnel corresponding to the first node is uploaded to the service platform node, and at the same time, the hash value of each service information record of the service personnel is entered into the chain for verification.
Preferably, the service authentication method further includes step S1B0. In step S1B0, the second node compares the obtained hash value of the service information record of the service personnel corresponding to the first node with the certificate record of the first node on the blockchain. If the hash value of the acquired service information record is consistent with the certificate record on the corresponding block chain, the service personnel information acquired by inquiring at the service platform node is true. If the hash value of the acquired service information record is inconsistent with the certificate record on the corresponding blockchain, the service personnel information acquired by inquiring in the service platform node may be forged.
Fig. 3 is a flow chart of a method of establishing digital identity according to an embodiment of the present application. As shown in fig. 3, in step S100, a third node (i.e., a digital identity establishment authority node) collects the biometric characteristics of the service person corresponding to the first node to generate a private key of the first node. The private key of the first node is calculated according to the biological characteristics of service personnel and based on a biological characteristic key generation algorithm of the chaotic system. The private key of the first node is subjected to an elliptic curve cryptography algorithm to generate a public key of the first node. The public key of the first node obtains the address of the first node through a series of hash operations. The collected biological characteristics are information of predetermined number of clear characteristic points of at least one biological characteristic of service personnel after data processing. The biological characteristics can be one or more characteristics of iris, DNA, electrocardiogram, retina, brain wave, infrared temperature spectrogram, vein and other information.
In step S200, the third node performs a blockchain-based identity token transaction with the first node to generate a third transaction ticket. The third transaction ticket includes a private key signature of the third node, an identity token, 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 based on the public key of the third node. If the third trade bill passes the verification, the digital identity of the service personnel corresponding to the first node is successfully established. The first node obtains the identity token by decrypting the third transaction ticket.
In the embodiment of the application, the establishment of the digital identity of the business personnel is completed through the identity token transaction based on the blockchain, so that the identity information of the business personnel is not concentrated in a central database any more, and the safety problems of data leakage, identity forging and the like can be effectively prevented.
Fig. 4 is a flowchart of a service information authentication method according to an embodiment of the present application. As shown in fig. 4, in step S400, a second node (i.e., a node where a consumer is located) performs a blockchain-based identity token transaction with a first node (i.e., a node where a business person is located) to generate a first transaction ticket. The first 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. The private key of the first node is calculated according to the biological characteristics of service personnel and based on a biological characteristic key generation algorithm of the chaotic system. The identity token includes an identification of predetermined query traffic personnel information. The identification of the information of the querying service personnel may be a hash value of the identity feature of the service personnel corresponding to the first node 1 or other information related to the identity information of the service personnel.
In step S500, a first transaction order is broadcast in a blockchain, and other nodes in the blockchain verify the first transaction order based on a public key of the first node. If the first transaction list passes the verification, the digital identity authentication of the service personnel corresponding to the first node is successful, and the second node acquires the identity token of the first node.
It should be understood that if the first transaction order fails verification, the digital identity authentication of the service personnel corresponding to the second node fails. That is, the information of the business person may be falsified.
In step S600, the second node performs a blockchain-based identity token transaction with the service platform node to generate a second transaction ticket, the second transaction ticket including a private key signature of the second node, an identity token of the first node, and an address of the service platform node.
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 second node. And if the second transaction order is verified, the service platform node obtains the identity token of the first node.
In step S700, the second node sends a request for acquiring service personnel information to the service platform node. Wherein the request for obtaining service personnel information includes an address of the first node.
In step S800, the service platform node queries the service personnel information corresponding to the first node according to the identifier of the queried service personnel information in the identity token, and returns a query result. Wherein the business person information includes business information records and credit records. The service information record includes a service type (e.g., insurance type, medical type, etc.) and an address of the first node. The service platform node evaluates the credit record of the service personnel by counting the corresponding service information record of the service personnel.
It should be appreciated that the second node may also send a request to the service platform node to obtain service personnel information while initiating a blockchain-based identity token transaction to the service platform node.
Preferably, after the identity token is used to log in to the service platform node to query the service personnel information, the identity token is set to fail to maintain the security 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 via 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 query is made, the identity token is destroyed and invalidated at the service platform node. That is, each identity token can only be queried once.
In the embodiment of the application, the identification of the digital identity of the business personnel is completed through the identity token transaction based on the blockchain, so that the business personnel can more conveniently and efficiently self-verify the identity. And the consumer inquires the business personnel information of the business personnel according to the information in the identity token, so that the inquired business personnel information is prevented from being fake information, the interference of false information is avoided, and the optimal consumption scheme is selected.
Further, the method for querying service information further includes step 900. In step 900, each service information record completed by the service personnel corresponding to the first node is uploaded to the service platform node, and at the same time, the hash value of each service information record of the service personnel is entered into the chain for verification.
Further, the method for querying service information further comprises step A00. In step a00, the second node compares the obtained hash value of the service information record of the service personnel corresponding to the first node with the certificate record of the first node on the blockchain. If the hash value of the acquired service information record is consistent with the certificate record on the corresponding block chain, the service personnel information acquired by inquiring at the service platform node is true. If the hash value of the acquired service information record is inconsistent with the certificate record on the corresponding block chain, the service personnel information acquired by inquiring in the service platform node has a forging phenomenon.
