Description

Technical Field

[0001] The present invention relates to the fields of blockchain and quantum encryption technologies, and particularly to a user identity authentication method and device based on blockchain. Background Art

[0002] This section aims to provide background or context for the embodiments of the present invention stated in the claims. The descriptions herein are not admitted to be prior art merely because they are included in this section.

[0003] Although 5G messaging technology brings many advantages such as high speed, low latency, and large capacity, traditional transaction reporting systems still face some security challenges and threats when combined with 5G messaging technology. During data transmission, if appropriate encryption and security measures are not taken, sensitive transaction data may be intercepted or stolen.

[0004] At present, in order to improve the accuracy of the user identity authentication scheme based on 5G messaging, it is mostly combined with 5G network slicing technology, relying on the introduction of independent configuration, monitoring, and maintenance for each slice of the 5G network. However, this will lead to an increase in management overhead, may introduce new configuration errors or vulnerabilities, and also increases the complexity of network management; if the slice management is improper, attackers may hijack or interfere with specific network slices, causing interference to the accuracy of user identity authentication and affecting the security and reliability of transaction reporting;

[0005] In addition, 5G network slicing technology allows the creation of multiple virtual networks. Under the premise that bank identity authentication involves multiple service providers and third-party applications, it will make the data flow in the user identity authentication process based on 5G network slices more complex, further increasing the risk of data leakage. Once data leakage occurs, not only the privacy rights of users are violated, but also legal liabilities and economic losses may be caused. Summary of the Invention

With the encoding mechanism of quantum keys and qubit superposition states, the security of data transmission is ensured. By using the quantum verification node to observe whether the quantum state of the quantum encoded data is a collapsed state, it means that any unauthorized observation or interference will be immediately detected. When it is determined that it is a collapsed state, it is determined that the quantum encoded data has been unauthorizedly observed during the data transmission process of the quantum encoded data, indicating that the current user authentication process is hijacked or interfered with specifically, achieving accurate detection of the transmission process of the quantum encoded data. Since there is no longer a need to create virtual networks for each service provider and third-party application, the problem in the prior art that the data flow in the user authentication process becomes more complex due to 5G network slicing technology, resulting in a low accuracy rate in the user authentication process, is solved, and the accuracy of the user authentication process is improved. Moreover, the dependence on complex network management is reduced, and the security risk caused by poor management is lowered. In addition, due to the vulnerability and collapse characteristics of quantum information, attackers cannot obtain or tamper with data without being detected, ensuring the security of the authentication process.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer and more understandable, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Herein, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0029] The term "and / or" in this article merely describes an association relationship, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the term "at least one" in this article means any one of multiple or any combination of at least two of multiple. For example, including at least one of A, B, and C can represent including any one or more elements selected from the set composed of A, B, and C.

[0030] In the description of this specification, the terms "include", "including", "have", "containing", etc. are all open-ended terms, meaning including but not limited to. The description with reference to terms such as "one embodiment", "one specific embodiment", "some embodiments", "for example", etc. means that the specific features, structures or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. The order of steps involved in each embodiment is used to schematically illustrate the implementation of the present application, and the order of steps is not limited and can be adjusted appropriately as needed.

[0031] In the technical solution of the present application, the acquisition, storage, use, processing, etc. of data all comply with the relevant provisions of national laws and regulations. The information collected in the present application is information and data authorized by the user or fully authorized by all parties, and the processing of relevant data, such as collection, storage, use, processing, transmission, provision, disclosure and application, all comply with the relevant laws, regulations and standards of relevant countries and regions, adopt necessary confidentiality measures, do not violate public order and good customs, and provide corresponding operation entrances for users to choose to authorize or refuse. In addition, the present application provides corresponding operation entrances for users to choose to agree or refuse the results of automated decision-making. If the user chooses to refuse, the expert decision-making process can be entered.

[0032] Although 5G messaging technology brings many advantages, such as high speed, low latency and large capacity, traditional transaction reporting systems still face some security challenges and threats when combined with 5G messaging technology. During data transmission, if appropriate encryption and security measures are not taken, sensitive transaction data may be intercepted or stolen.

[0033] At present, in order to improve the accuracy of the user identity authentication scheme based on 5G messaging, it is often combined with 5G network slicing technology, relying on the introduction of configuration, monitoring and maintenance for each slice of the 5G network independently. However, this will lead to an increase in management overhead, may introduce new configuration errors or vulnerabilities, and also increases the complexity of network management; if the slice management is improper, attackers may hijack or interfere with specific network slices, disturbing the accuracy of user identity authentication and affecting the security and reliability of transaction reporting; due to the dynamics and diversity of network slices, real-time monitoring and rapid response to security incidents become more complex. Efficient monitoring tools and automated response mechanisms are needed to cope with the ever-changing security threats.

[0034] In addition, the 5G network slicing technology allows for the creation of multiple virtual networks. Given that bank identity authentication involves multiple service providers and third-party applications, the data flow in the user identity authentication process based on 5G network slicing becomes more complex, further increasing the risk of data leakage. Once data leakage occurs, not only the user's privacy rights are violated, but also legal liabilities and economic losses may result.

[0035] Although network slicing aims to provide logical isolation, it may be difficult to achieve complete isolation in actual operation. For example, the sharing of physical resources may lead to potential data leakage or interference between different slices. Attackers may attempt to attack one slice through another. Although network slicing provides isolation, attackers may exploit the shared parts of the network or management interfaces to carry out cross-slice attacks.

[0036] To solve the above problems, embodiments of the present invention provide a blockchain-based user identity authentication method to enhance the transmission security of data involved in user identity authentication, improve the accuracy of the user identity authentication process, reduce the dependence on complex bank network management, and lower security risks. See Figure 1 , the method may include:

[0037] Step 101: Obtain multi-modal identity authentication information generated when a user performs user identity authentication on a client based on a probe program;

[0038] Step 102: For each multi-modal identity authentication information, encode the multi-modal identity authentication information based on the target qubit superposition state information generated by a quantum key to obtain quantum-encoded data; the quantum key is generated by a quantum random number corresponding to the multi-modal identity authentication information;

[0039] Step 103: Send a 5G message carrying the quantum-encoded data to a quantum verification node of the blockchain through a pre-set user SIM card; the blockchain includes a quantum verification node and a bank authentication node; the quantum verification node is used to observe whether the qubit superposition state information carried by the quantum-encoded data is a collapsed state; the collapsed state is used to describe the quantum state presented by the qubit superposition state information in the quantum-encoded data after unauthorized observation; when the target qubit superposition state information is not a collapsed state, send the quantum-encoded data to the bank authentication node; the bank authentication node is used to decrypt the quantum-encoded data; perform user identity authentication on the decrypted quantum-encoded data;

[0040] Step 104: After the identity authentication performed by the bank authentication node passes, send a notification message indicating that the identity authentication has passed to the user's client.

[0041] In step 101, obtaining the multi-modal authentication information generated during user identity authentication by the user on the client based on the probe program may include the following aspects: information such as passwords, fingerprints, and facial recognition input by the user. This information will be collected in real time through the probe program and used for subsequent quantum encoding and identity authentication processes.

[0042] In step 102, for each multi-modal authentication information, based on the target qubit superposition state information generated by the quantum key, the multi-modal authentication information is encoded to obtain quantum encoded data. The core of this step is the generation of the quantum key and the generation of the quantum encoded data. The quantum key generator will generate corresponding quantum random numbers based on the user's multi-modal authentication information, thereby ensuring the uniqueness and security of the quantum key. The generated quantum encoded data will be used for subsequent blockchain transmission and bank authentication.

[0043] In step 103, through the pre-set user SIM card, a 5G message carrying the quantum encoded data is sent to the quantum verification node of the blockchain. In this step, the transmission of the 5G message plays a key role. It transmits the quantum encoded data from the user client to the quantum verification node of the blockchain, providing the possibility for subsequent observation of the qubit superposition state information and bank authentication.

[0044] In step 104, the bank authentication node decrypts the quantum encoded data and authenticates the user's identity for the decrypted quantum encoded data. This step ensures that only authorized users can pass the identity authentication, thereby improving the security and accuracy of the entire authentication process. After the identity authentication is passed, the bank authentication node will send a notification message of successful identity authentication to the user's client to complete the entire identity authentication process.

[0045] In an embodiment of the present invention, multi-modal authentication information generated when a user performs user authentication on a client based on a probe program is obtained; for each multi-modal authentication information, based on the target qubit superposition state information generated by a quantum key, the multi-modal authentication information is encoded to obtain quantum-encoded data; the quantum key is generated by a quantum random number corresponding to the multi-modal authentication information; through a pre-set user SIM card, a 5G message carrying the quantum-encoded data is sent to a quantum verification node of a blockchain; the blockchain includes a quantum verification node and a bank authentication node; the quantum verification node is used to observe whether the qubit superposition state information carried by the quantum-encoded data is a collapsed state; the collapsed state is used to describe the quantum state presented by the qubit superposition state information in the quantum-encoded data after unauthorized observation; when the target qubit superposition state information is not a collapsed state, the quantum-encoded data is sent to the bank authentication node; the bank authentication node is used to decrypt the quantum-encoded data; user authentication is performed on the decrypted quantum-encoded data; after the authentication performed by the bank authentication node passes, a notification message indicating that the authentication has passed is sent to the client of the user, so that the security of user authentication can be strengthened through quantum technology and 5G message technology. With the coding mechanism of quantum keys and qubit superposition states, the security of data transmission is ensured. By using the quantum verification node to observe whether the quantum state of the quantum-encoded data is a collapsed state, it means that any unauthorized observation or interference will be immediately detected. When it is determined that it is a collapsed state, it is determined that the quantum-encoded data has been unauthorizedly observed during the data transmission process of the quantum-encoded data, indicating that the current user authentication process is hijacked or interfered with specifically, and accurate detection of the transmission process of the quantum-encoded data is achieved; since there is no longer a need to create virtual networks for each service provider and third-party application, the problem in the prior art that the data flow in the user authentication process becomes more complex due to 5G network slicing technology, resulting in a low accuracy rate of the user authentication process, is solved, and the accuracy of the user authentication process is improved; moreover, the dependence on complex network management is reduced, and the security risk caused by poor management is lowered; in addition, due to the vulnerability and collapse characteristics of quantum information, an attacker cannot obtain or tamper with data without being detected, ensuring the security of the authentication process.

[0046] In specific implementation, first, multi-modal authentication information generated when a user performs user authentication on a client based on a probe program is obtained.

[0047] In an embodiment, the probe program will utilize the APIs provided by the operating system (such as Android's AccessibilityService API and iOS's UITextServices) to monitor the user's input behavior on the login interface. To improve the accuracy of identification, multi-modal biometric technologies will be adopted, combining the user's typing dynamics, touchscreen behavior, and biometric features (such as fingerprint and facial recognition) for authentication. These data will be analyzed through a deep learning model (such as Convolutional Neural Network CNN) to identify legitimate users and potential fraud behaviors.

[0048] In one embodiment, the probe program is embedded into a specified bank APP in the user client based on a pre-set application programming interface; the multi-modal authentication information includes key sequences, touchscreen operations, and biometric data.

[0049] For example, when a user attempts to log in to the bank APP, the probe program will be automatically launched to start monitoring the user's input behavior. The probe program will record the key sequence and touchscreen operations of the user on the login interface. At the same time, if the user selects biometric authentication, the probe program will also collect the user's biometric data. This information will be sent to the server side for analysis through a deep learning model.

[0050] As Figure 2 shown, the probe program is used to perform the following steps:

[0051] Step 201: Based on a pre-set application programming interface, listen for user interaction events related to user authentication;

[0052] Step 202: Capture the multi-modal authentication information in the user interaction event.

[0053] In an embodiment, the probe program will use the APIs provided by the operating system (for example, Android's AccessibilityService or iOS's Keyboard Extension) to listen for and capture user interaction events related to authentication. When the user performs authentication, the probe program will record relevant user behavior data, such as key sequences, touchscreen operations, biometric data, etc. These data will be used for subsequent authentication and security analysis.

[0054] In the above embodiment, the probe program can be installed on the user device to ensure that the probe program is compatible with the device's operating system and has the necessary permissions to monitor authentication events. The process of configuring the probe is as follows: Configure the probe program to listen for specific authentication events, such as login attempts, password input, biometric authentication, etc. The probe program needs to be configured to be activated only when the user performs an authentication operation to minimize interference with the user's daily use.

[0055] Specifically, after obtaining the multi-modal authentication information generated during user identity authentication on the client side based on the probe program, for each piece of multi-modal authentication information, based on the target qubit superposition state information generated by the quantum key, the multi-modal authentication information is encoded to obtain quantum-encoded data; the quantum key is generated by a quantum random number corresponding to the multi-modal authentication information.

[0056] In the embodiment, during the quantum encoding stage, the security server will use a specific quantum algorithm, such as amplitude encoding or phase encoding, to map the multi-modal authentication information to the state of qubits. In this way, each qubit superposition state information contains an encrypted version of the original authentication information, forming quantum-encoded data.

[0057] In one embodiment, a user identity authentication method based on blockchain provided by the embodiments of the present invention, as Figure 3 shown, may further include the following steps:

[0058] Step 301: For each piece of multi-modal authentication information, send a request instruction corresponding to the multi-modal authentication information to the quantum random number generator; the quantum random number generator is used to generate a random sequence based on the uncertainty principle of quantum mechanics after receiving the request instruction; and send the random sequence as the quantum random number corresponding to the multi-modal authentication information;

[0059] Step 302: Receive the quantum random number corresponding to the multi-modal authentication information sent by the quantum random number generator according to the request instruction;

[0060] Step 303: Based on the quantum random number corresponding to the multi-modal authentication information, create a quantum key and a decryption key corresponding to the quantum key.

[0061] In the embodiment, the quantum key distribution (QKD) technology is used to generate and distribute keys. These keys are based on the principles of quantum mechanics and provide unbreakable security. Even if the encryption technology of the 5G network is cracked, quantum encryption can provide an additional security layer.

[0062] The probe program transmits this information to the security server, and the quantum random number generator (QRNG) running on the server will generate a series of random numbers based on the uncertainty principle of quantum mechanics to form a quantum key. These quantum keys will be used in the subsequent quantum encoding process to ensure that each authentication information has a unique qubit superposition state information corresponding to it.

[0063] In an embodiment, during the data transmission process, quantum state markers (such as the superposition state of qubits) are used to represent sensitive information. Any unauthorized observation or interference will cause a change in the quantum state, which can be immediately detected. By using quantum keys and qubit superposition state information, this method provides a highly secure encoding mechanism for user authentication information. The generation of quantum keys is based on quantum random numbers, ensuring the true randomness and unpredictability of the keys, thereby improving the security of data transmission.

[0064] For example, assume that a user uses a probe program on a client device for authentication. The probe program will capture multimodal authentication information such as passwords and biometric data entered by the user on the keyboard or touch screen. This information will be sent to a security server, and the quantum random number generator on the server will generate corresponding quantum random numbers based on this information.

[0065] Next, the security server uses specific quantum algorithms, such as amplitude encoding or phase encoding, to map the multimodal authentication information to the state of qubits. In this way, each qubit superposition state information contains an encrypted version of the original authentication information, forming quantum-encoded data.

[0066] Subsequently, the security server stores the quantum-encoded data on the blockchain to ensure the credibility and immutability of the data. The quantum-encoded data stored on the blockchain can be used for subsequent authentication and security analysis. In addition, the decentralized nature of the blockchain also ensures the security and privacy of the data.

[0067] When user authentication is required, the security server retrieves the corresponding quantum-encoded data from the blockchain and decrypts it using the decryption key generated by the quantum random number generator. The decrypted authentication information will be used to verify the user's identity.

[0068] Throughout the process, the quantum random number generator and quantum algorithms ensure the secure transmission and encryption of authentication information. At the same time, blockchain technology guarantees the authenticity, integrity, and immutability of the data. This blockchain-based user authentication method provides users with a more secure and reliable authentication method.

[0069] In one embodiment, the blockchain further includes a user information node;

[0070] The method further includes: sending the decryption key in the created key pair to the user information node corresponding to the user in the blockchain;

[0071] The bank authentication node is specifically configured to: decrypt the quantum-encoded data based on the decryption key obtained from the user information node.

[0072] The following are the steps for creating a blockchain in the present invention:

[0073] 1. User Information Node

[0074] Function: The user information node is responsible for storing and managing the personal information and identity authentication data of users in the blockchain.

[0075] Example:

[0076] When users register, their basic information (such as name, contact information, etc.) and identity authentication information (such as the hash value of biometric data) are encrypted and stored in the user information node.

[0077] This information can be encrypted with the user's public key to ensure that only authorized entities (such as bank authentication nodes) can decrypt and access this information.

[0078] The user information node can also store the transaction history and authentication records of users, providing the necessary information for auditing and supervision.

[0079] 2. Quantum Verification Node

[0080] Function: The quantum verification node is responsible for verifying the integrity and security of quantum-encoded data, ensuring that the data has not been tampered with or accessed without authorization during transmission.

[0081] Example:

[0082] When users authenticate through the client, the quantum verification node receives a 5G message containing quantum-encoded data.

[0083] The quantum verification node uses a quantum measurement device to observe the qubit superposition state information in the quantum-encoded data and checks for the presence of collapsed states.

[0084] If the observation result shows that the qubit superposition state information has not collapsed, the quantum verification node will confirm the validity of the data and continue with the subsequent authentication process.

[0085] 3. Bank Authentication Node

[0086] Function: The bank authentication node is used to decrypt the quantum-encoded data, authenticate the user's identity, and finally decide whether to approve the user's transaction request.

[0087] Example:

[0088] Once the quantum verification node verifies the validity of the quantum-encoded data, the data will be sent to the bank authentication node.

[0089] The bank authentication node uses the decryption key corresponding to the quantum key to decrypt the quantum-encoded data and recover the original multimodal identity authentication information.

[0090] The bank authentication node compares the decrypted information with the data stored in the user information node to complete the identity verification process.

[0091] If the identity verification is successful, the bank authentication node will send a notification message of successful identity verification to the user's client and process the user's transaction request.

[0092] Through the collaborative work of these three nodes, your blockchain user identity authentication method can provide efficient and accurate identity authentication services while ensuring the security of data transmission. The user information node protects user privacy, the quantum verification node ensures the security of data transmission, and the bank authentication node is responsible for the final identity verification and transaction processing.

[0093] In one embodiment, for each multimodal identity authentication information, based on the target qubit superposition state information generated by the quantum key, the multimodal identity authentication information is encoded to obtain quantum encoded data, as Figure 4 shown including:

[0094] Step 401: Using photons as the quantum system, based on the quantum key, generate the target qubit superposition state information corresponding to the quantum key through the amplitude encoding algorithm;

[0095] Step 402: Embed the target qubit superposition state information into the data packet of the multimodal identity authentication information to obtain quantum encoded data.

[0096] In one embodiment, the amplitude encoding algorithm is used to represent two consecutive bits with different combinations formed by the polarization states of two photons;

[0097] Using photons as the quantum system, based on the quantum key, generate the target qubit superposition state information corresponding to the quantum key, including:

[0098] Using photons as the quantum system, map the bits of the quantum key through the amplitude encoding algorithm to a set of polarization state combinations of photons;

[0099] Take the set as the target qubit superposition state information corresponding to the quantum key.

[0100] Take an example to illustrate the above process of generating a random sequence and embedding the target qubit superposition state information into the data packet of the multimodal identity authentication information, including the following steps:

[0101] 1. Quantum key distribution (QKD) establishes a secure communication channel

[0102] Deploy QKD devices at the user end and the receiving end, which can generate, send, and measure qubits (quantum bits). Commonly used QKD protocols include BB84 and Ekert91, which can encode information based on the polarization state or phase state of photons.

[0103] Establish a quantum channel through optical fiber or free-space communication. In optical fiber, photons encoded with polarization states can be used; in free space, photons encoded with phase states assisted by satellites or drones can be used.

[0104] Through the QKD protocol, both parties generate a shared and random key. This key will be used in the subsequent encoding and embedding processes of quantum state tags.

[0105] 2. Generation of Quantum State Tags

[0106] Use a quantum random number generator (QRNG) to generate a random sequence. QRNGs usually rely on the uncertainty principle of quantum mechanics, such as quantum tunneling effect or spontaneous emission of photons.

[0107] Encode the random number sequence into quantum states. This can be achieved by manipulating the polarization state or phase state of photons. For example, two polarization states (such as horizontal and vertical) can be used to represent binary digits 0 and 1.

[0108] 3. Embedding of Quantum State Tags

[0109] Combine the user's identity authentication information with the quantum state tags. This can be achieved by mapping each bit of the authentication information to a quantum state. For example, if the authentication information is "1101", then photons with two polarization states can be created, one representing "10" and the other representing "11".

[0110] Integrate the encoded quantum states with the data packet of the authentication information. This usually involves embedding the quantum states into a certain part of the data packet, such as the header or tail of the data packet.

[0111] 4. Transmission of Quantum State Tags

[0112] Quantum channel transmission: Send the data packet with quantum state tags to the receiving end through the established quantum channel. During the transmission process, any unauthorized observation will cause the collapse of the quantum state, which will be detected by the sending end and the receiving end.

[0113] 5. Verification of Quantum State Tags

[0114] At the receiving end, use a quantum measurement device to measure the received quantum states. The measurement results will be used to verify the validity of the quantum state tags. Once the quantum state tags are verified as valid, the receiving end will decode the quantum state tags and extract the original identity authentication information from them.

[0115] Another example is given to illustrate the above process of encoding multi-modal identity authentication information:

[0116] Information encoding is a process of converting classical information (such as a user's identity authentication information) into a quantum state. This process enables the information to be processed and transmitted at the quantum level. In the example you mentioned, encoding the user's identity authentication information (bit string) into a quantum state, specifically, using the polarization state of photons to represent each bit, can include the following steps:

[0117] 1. Select a quantum system: In this example, photons are selected as the quantum system because they can carry quantum information and propagate in space.

[0118] 2. Define an encoding scheme: An encoding scheme needs to be defined to map classical bits to quantum states. In this example, two different polarization states can be used to represent two bits. For example, horizontal polarization (H) can represent "10", vertical polarization (V) can represent "01", and diagonal polarization (e.g., +45° represents D+ or -45° represents D-) can represent "1" or "0".

[0119] 3. Encode the information: Now, the bit string "1101" needs to be encoded into a quantum state. According to the encoding scheme, two photons can be created:

[0120] The first photon represents "1", and its polarization state can be set to D+ (+45°).

[0121] The second photon represents "0", and its polarization state can be set to D- (-45°).

[0122] The third photon represents "1", and D+ (+45°) is selected again.

[0123] The fourth photon represents "1", and D+ (+45°) is selected again.

[0124] 4. Create and send the quantum state: By using quantum optical devices (such as lasers and wave plates) to create and manipulate the polarization state of photons, the quantum state defined above can be generated. Once these quantum states are created, they can be transmitted to the receiving end through optical fibers or free space.

[0125] 5. Measurement of the quantum state: At the receiving end, an appropriate quantum measurement device (such as a polarization analyzer) is used to measure the polarization state of each photon. According to the measurement results, the receiving end can decode the original bit string "1101".

[0126] In this way, the user's identity authentication information can be encoded into the quantum state and transmitted while maintaining information security. It should be noted that this process requires highly precise equipment and technology to ensure the accurate creation and measurement of the quantum state.

[0127] In the above embodiment, once the quantum-encoded data is successfully created and embedded into the data packet of the multi-modal identity authentication information, the following steps will ensure the secure transmission and effective verification of this data.

[0128] First, through the pre-set user SIM card, the quantum-encoded data will be encapsulated in a 5G message and sent to the quantum verification node in the blockchain network. This step utilizes the high rate and low latency characteristics of the 5G network to ensure the efficiency and real-time nature of data transmission. At the quantum verification node, a series of quantum measurement operations will be performed to verify the integrity of the qubit superposition state information. If the quantum-encoded data has not been subjected to unauthorized observation or interference, the quantum verification node will confirm that its state has not collapsed, thus proving that the data has maintained its quantum characteristics during transmission and has not been tampered with.

[0129] After successful verification, the quantum-encoded data will be forwarded to the bank authentication node. At the bank authentication node, the decryption key corresponding to the quantum key will be used to decrypt the quantum-encoded data. This decryption process will restore the original multi-modal identity authentication information, enabling the bank to accurately authenticate the user. After successful identity authentication, the bank authentication node will send a notification message indicating successful identity authentication to the user's client. This notification message can be directly sent to the user's device through the 5G messaging service, providing instant feedback to the user.

[0130] In addition, to improve the transparency and traceability of the system, all operations and results related to identity authentication will be recorded on the blockchain. This not only ensures the immutability of transactions but also provides a clear audit trail for regulatory authorities and audits. Through this method combining quantum technology and blockchain, the embodiment of the present invention provides a highly secure user identity authentication solution that can not only resist potential cyberattacks but also protect the privacy and data security of users in a complex environment involving multiple service providers and third-party applications.

[0131] In specific implementation, for each multimodal authentication information, based on the target qubit superposition state information generated by a quantum key, the multimodal authentication information is encoded to obtain quantum-encoded data, and then, through a pre-set user SIM card, a 5G message carrying the quantum-encoded data is sent to a quantum verification node of a blockchain; the blockchain includes a quantum verification node and a bank authentication node; the quantum verification node is used to observe whether the qubit superposition state information carried by the quantum-encoded data is a collapsed state; the collapsed state is used to describe the quantum state presented by the qubit superposition state information in the quantum-encoded data after unauthorized observation; when the target qubit superposition state information is not a collapsed state, the quantum-encoded data is sent to the bank authentication node; the bank authentication node is used to decrypt the quantum-encoded data; and user identity authentication is performed on the decrypted quantum-encoded data.

[0132] In the embodiment, through the user's SIM card, the quantum-encoded data will be sent to the quantum verification node in the blockchain network through the 5G network. The quantum verification node will perform quantum measurement to verify whether the qubit superposition state information remains in its original state, that is, no collapse occurs. If the quantum-encoded data has not been observed or interfered with by an unauthorized third party, the quantum verification node will confirm it as valid data.

[0133] In one embodiment, as Figure 5 shown, the quantum verification node is specifically used to perform the following steps:

[0134] Step 501: Determine the qubit superposition state information in the quantum-encoded data received through the pre-set quantum channel;

[0135] Step 502: Based on a quantum measurement device, observe the quantum state of the qubit superposition state information;

[0136] Step 503: When the observation result indicates that the target qubit superposition state information is a collapsed state, send an alarm message that the transmission process of the quantum-encoded data has been unauthorizedly observed and the user's identity authentication fails.

[0137] In the embodiment, the quantum verification node receives the quantum-encoded data and uses a quantum measurement device to observe the qubit superposition state information in the data. The quantum measurement device can accurately measure the state of the qubit, including the polarization state and other quantum characteristics.

[0138] If it is found during the observation process that the superposition state information of the qubit has collapsed, this indicates that the quantum-encoded data may have been unauthorizedly observed or interfered with during the transmission process. The collapsed state refers to the situation where the qubit changes from the superposition state to a definite classical state, which is usually caused by external interference or measurement.

[0139] Once the quantum verification node confirms that the qubit superposition state information has collapsed, the system will automatically trigger the alarm mechanism. The quantum verification node will send an alarm message indicating that the transmission process of the quantum-encoded data may have been compromised by unauthorized observation. Since the security of the quantum-encoded data is threatened, the bank authentication node will not continue the identity authentication process. The system will send a notification to the user, informing them that the identity authentication has failed and may suggest that the user re-perform the identity authentication or take other security measures.

[0140] Through this example, any unauthorized attempt to access or interfere with the quantum-encoded data will be detected and promptly notified to the system and the user through an alarm message, thus preventing potential security threats.

[0141] In another specific embodiment, the quantum verification node is specifically used for:

[0142] If the quantum verification node confirms that the qubit superposition state information has not collapsed, indicating that the data has not been subject to unauthorized observation or interference during transmission, the verified quantum-encoded data will be forwarded to the bank authentication node in the blockchain network. The bank authentication node is responsible for further processing and verifying the user's identity authentication information.

[0143] The bank authentication node will decrypt the quantum-encoded data using a pre-allocated decryption key. This decryption process will recover the original multi-modal identity authentication information, including the user's biometric data and other authentication information.

[0144] The decrypted information will be compared with the user profile in the bank database to complete the authentication process. If all the information matches, the bank authentication node will confirm the user's identity and perform relevant transactions or services for the user.

[0145] Once the authentication is successful, the bank authentication node will send a notification message of successful authentication to the user's client through the 5G messaging service. This notification will inform the user that their authentication request has been accepted and they can safely continue their transactions or other activities.

[0146] Specifically, at the beginning of the transaction, the client device creates a unique quantum state tag by connecting to a quantum random number generator. This tag is generated based on the principles of quantum mechanics and thus has true randomness and unpredictability. The generated quantum state tag is encoded into a sequence of qubits, and these qubits are in a superposition state. This sequence is then embedded in the dynamic password and sent to the bank server. The quantum state tag is protected by the principles of quantum mechanics during transmission. Any unauthorized observation or interference will cause the wave function of the qubit to collapse, thus changing its state.

[0147] The bank's server is equipped with a quantum communication receiver for receiving and detecting the transmitted quantum state tags. The server observes the quantum state through a specific quantum measurement process to verify its integrity. If the quantum state tag is not interfered with during transmission, the server will successfully detect the original quantum state, thus confirming the security of the transaction. If the quantum state tag changes, the server will be aware of a possible security threat and take corresponding security measures, such as rejecting the transaction, issuing an alarm, or initiating additional verification procedures.

[0148] In one embodiment, a quantum computer or a quantum simulator can be deployed on the server side to perform the measurement and verification of the quantum state. The measurement results will be corrected by a quantum error correction algorithm to eliminate the noise and interference that may occur during transmission. In addition, the quantum key distribution (QKD) technology, such as the Ekert91 protocol, will be adopted to verify the authenticity of the quantum state tag.

[0149] In the above embodiment, the role of the quantum inspection node is to detect whether the qubit superposition state information in the quantum-encoded data is in a collapsed state, which means that any unauthorized observation or interference will be immediately detected. This detection mechanism can effectively prevent unauthorized access and data leakage.

[0150] Even if an attacker intercepts the quantum-encoded data, due to the vulnerability and collapse characteristics of quantum information, the attacker cannot obtain or tamper with the data without being detected.

[0151] In specific implementation, after sending a 5G message carrying the quantum-encoded data to the quantum inspection node of the blockchain through a pre-set user SIM card, after the identity authentication at the bank authentication node passes, a notification message of successful identity authentication is sent to the client of the user.

[0152] In the embodiment, after the verification passes, the quantum-encoded data will be sent to the bank authentication node, and this node will decrypt the quantum-encoded data using a pre-allocated decryption key to restore the original multimodal identity authentication information. The bank authentication node will compare this information with the user profile to complete the identity verification process. Once the identity verification is successful, the bank authentication node will send a confirmation message to the client of the user, notifying the user that their identity authentication has passed. In this way, the user can safely perform subsequent transactions and operations, and the security of the entire identity authentication process is guaranteed by both quantum technology and 5G message technology.

[0153] In the above embodiments, blockchain technology provides a distributed and decentralized ledger. Once data is recorded on the blockchain, it cannot be changed or deleted. This ensures the integrity of transaction data and the audit trail. Through blockchain technology, the method achieves decentralized identity authentication and data storage, which reduces the dependence on a single network slice or a centralized management point, thereby reducing the risks caused by management errors or attacks on network slices.

[0154] In the embodiments of the present invention, multi-modal identity authentication information generated when a user performs user identity authentication on a client based on a probe program is obtained; for each multi-modal identity authentication information, based on the target qubit superposition state information generated by a quantum key, the multi-modal identity authentication information is encoded to obtain quantum-encoded data; the quantum key is generated by a quantum random number corresponding to the multi-modal identity authentication information; through a pre-set user SIM card, a 5G message carrying the quantum-encoded data is sent to a quantum verification node of the blockchain; the blockchain includes a quantum verification node and a bank authentication node; the quantum verification node is used to observe whether the qubit superposition state information carried by the quantum-encoded data is a collapsed state; the collapsed state is used to describe the quantum state presented by the qubit superposition state information in the quantum-encoded data after unauthorized observation; when the target qubit superposition state information is not a collapsed state, the quantum-encoded data is sent to the bank authentication node; the bank authentication node is used to decrypt the quantum-encoded data; user identity authentication is performed on the decrypted quantum-encoded data; after the identity authentication performed by the bank authentication node passes, a notification message indicating that the identity authentication has passed is sent to the client of the user. Thus, the security of user identity authentication can be enhanced through quantum technology and 5G message technology. By means of the encoding mechanism of quantum keys and qubit superposition states, the security of data transmission is ensured. By using the quantum verification node to observe whether the quantum state of the quantum-encoded data is a collapsed state, it means that any unauthorized observation or interference will be immediately detected. When it is determined that it is a collapsed state, it is determined that the quantum-encoded data has been unauthorizedly observed during the data transmission process of the quantum-encoded data, indicating that the current user identity authentication process is hijacked or interfered with specifically, achieving accurate detection of the transmission process of the quantum-encoded data; since there is no longer a need to create virtual networks for each service provider and third-party application, the problem in the prior art that the data flow in the user identity authentication process becomes more complex due to the 5G network slicing technology, resulting in a low accuracy rate of the user identity authentication process, is solved, and the accuracy of the user identity authentication process is improved; moreover, the dependence on complex network management is reduced, and the security risks caused by poor management are lowered; in addition, due to the vulnerability and collapse characteristics of quantum information, attackers cannot obtain or tamper with data without being discovered, ensuring the security of the identity authentication process.

[0155] In an embodiment of the present invention, a user identity authentication device based on blockchain is further provided, as described in the following embodiments. Since the principle of this device for solving problems is similar to that of the user identity authentication method based on blockchain, the implementation of this device can refer to the implementation of the user identity authentication method based on blockchain, and the repeated parts will not be elaborated.

[0156] An embodiment of the present invention further provides a user identity authentication device based on blockchain, which is used to improve the transmission security of data involved in user identity authentication, improve the accuracy of the user identity authentication process, reduce the dependence on complex bank network management, and reduce security risks. As Figure 6 shown, the device includes:

This decryption key is generated during the user registration or authentication process and corresponds to the quantum key, and is used to decrypt the quantum-encoded data. The bank authentication node uses the obtained decryption key to decrypt the quantum-encoded data to recover the original multimodal authentication information. The decryption process involves converting the superposition state of quantum bits back to classical information, which usually requires specific quantum decoding algorithms and keys.

[0173] The bank authentication node compares the decrypted information with the user profile in the bank database to complete the authentication process. If all information matches, the bank authentication node will confirm the user's identity and allow the user to access their account or perform transactions.
