[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] The vehicle network identity authentication method for a highway provided by an embodiment of the present invention is executed by a computer device, and accordingly, the vehicle network identity authentication system for a highway runs in the computer device.

[0026] Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention. Figure 1 The execution subject may be a vehicle network identity verification system for a highway. According to different requirements, the order of the steps in the flowchart may be changed, and some may be omitted.

[0027] like Figure 1 As shown, the method includes: Step 110, acquiring a vehicle image at a detection node on the highway, and identifying a license plate number from the vehicle image; Step 120, retrieving an identity identifier having a mapping relationship with the license plate number from an identity information database, wherein the identity information database stores the identity identifiers and license plate numbers of registered Internet of Vehicles terminals; Step 130: Send the identity identifier to multiple roadside devices deployed at the detection node, so that the multiple roadside devices can authenticate the identity of the Internet of Vehicles terminal that sends the request based on the identity identifier.

[0028] To facilitate understanding of the present invention, the following is a further description of the vehicle networking identity authentication method for highways provided by the present invention based on the principle of the vehicle networking identity authentication method for highways of the present invention and the process of identity authentication of the vehicle networking terminal for highways in the embodiment.

[0029] Specifically, the vehicle network identity authentication methods for highways include: S1. Equipment deployment.

[0030] Multiple detection nodes are deployed on the highway in advance, and each detection node is equipped with an image acquisition device and multiple roadside equipment.

[0031] Among them, the image acquisition device can be set in front of multiple roadside devices so that the vehicle passes the image acquisition device first and then passes the roadside device, thereby providing sufficient time for the roadside device to perform identity verification.

[0032] S2. Identity registration.

[0033] Receive registration data sent by a vehicle networking terminal, the registration data including personal identity information and a license plate number; calculate the MD5 value of the personal identity information and the MD5 value of the license plate number, and integrate the MD5 value of the personal identity information and the MD5 value of the license plate number into an identity identifier of the vehicle networking terminal; and send the identity identifier to the vehicle networking terminal.

[0034] Receive registration data sent by a third-party terminal, the registration data including personal identity information, generate a personal account based on the third-party terminal, and use the MD5 value of the personal identity information as the management identity of the personal account; establish a binding relationship between the identity of the Internet of Vehicles terminal including the management identity and the personal account; save the management identity of the personal account, the identity of the bound Internet of Vehicles terminal and the corresponding registration data to an identity information database.

[0035] Specifically, in the registration and identity management process of the Internet of Vehicles system, first, the system will receive detailed registration data sent from the Internet of Vehicles terminal. These data include but are not limited to the user's personal identity information (sensitive information such as name, ID number, etc., which must be handled in accordance with the privacy protection principle) and the vehicle's license plate number. In order to ensure the security and privacy of the data, the system will encrypt these key information by calculating the MD5 value of the personal identity information (a widely used hash function that can convert information of any length into a hash value of a fixed length, and the process is irreversible) and the MD5 value of the license plate number. Subsequently, the system integrates these two MD5 values ​​into a unique identity identifier, which will serve as the only identity authentication basis for the Internet of Vehicles terminal in subsequent interactions and will be securely sent back to the Internet of Vehicles terminal for storage.

[0036] Next, the system will also process registration requests from third-party terminals (such as mobile apps, web platforms, etc.). These registration data mainly revolve around the user's personal identity information. Based on this information, the system generates a personal account for the user, and also uses the MD5 algorithm to encrypt the personal identity information to generate a management identity. This management identity is not only used to protect the user's privacy, but also serves as a credential for the user to manage his or her Internet of Vehicles terminal and related services.

[0037] In order to establish a close connection between the Internet of Vehicles terminal and the personal account, the system will bind the previously generated Internet of Vehicles terminal identity to the management identity of the personal account and record this binding relationship. At the same time, the system will also securely save the management identity of the personal account, the bound Internet of Vehicles terminal identity, and all related registration data (under the premise of complying with the privacy policy) in a dedicated identity information database. This step ensures the integrity, consistency and traceability of the data, laying a solid foundation for subsequent identity authentication, permission management and service provision.

[0038] S3. Acquire a vehicle image at a detection node on the highway, and identify a license plate number from the vehicle image.

[0039] Using the OpenCV model to recognize the license plate number, specifically, from a complete license plate image to recognizing the characters on the license plate, it takes the following steps: Preprocessing: grayscale and binarize the license plate image, and remove interference factors during recognition, such as license plate rivets; Character segmentation: split the entire license plate image into 7 separate character images according to each character and save them into a collection; Character recognition: Use the trained feature set of numbers, English characters, and Chinese characters to recognize the character image and obtain the final license plate number.

[0040] S4. Retrieve an identity identifier that has a mapping relationship with the license plate number from an identity information database, wherein the identity information database stores the identity identifiers and license plate numbers of registered Internet of Vehicles terminals.

[0041] Calculate the MD5 value of the recognized license plate number, use the MD5 value as the target data, and query the identity identifier containing the target data from the identity information database.

[0042] S5. Send the identity identifier to multiple roadside devices deployed at the detection node, so that the multiple roadside devices authenticate the identity of the Internet of Vehicles terminal that sends the request based on the identity identifier.

[0043] After confirming the vehicle's identity, the system sends the identified identity to multiple roadside devices deployed along the highway. These roadside devices include but are not limited to traffic light controllers, variable message signs (VMS), ETC toll collection systems, etc. They perform identity authentication and permission management on the connected vehicle terminals that are about to enter their service areas based on the received identity.

[0044] S6. The roadside device performs identity authentication.

[0045] The roadside device updates the received identity to the register by overwriting the original data; the roadside device receives the request sent by the vehicle networking terminal and extracts the identity to be verified from the request. The roadside device determines whether the identity to be verified is consistent with the identity in the register: if so, the request is executed; if not, the request is ignored.

[0046] The specific process of roadside equipment performing identity authentication is as follows: Update register: After receiving the identity information, the roadside device first updates it to the local register by overwriting the original data. This ensures that the latest identity information is used for each verification, preventing verification failures caused by information lag.

[0047] Request processing: When the Internet of Vehicles terminal sends a service request to the roadside device (such as paying through the ETC lane, requesting lane change instructions, etc.), the roadside device will extract the identity to be verified from the request.

[0048] Consistency judgment: The roadside device compares the identity to be verified with the identity stored in the register. If the two are consistent, it means that the vehicle network terminal has passed the identity authentication, and the roadside device will execute its request (such as opening the ETC lane barrier, displaying lane change instructions, etc.); if they are inconsistent, the request will be ignored and the safety alarm mechanism may be triggered.

[0049] S7. Record data management.

[0050] Collect data interaction records between roadside equipment and Internet of Vehicles terminals, and send the data interaction records to a personal account bound to the Internet of Vehicles terminal.

[0051] In order to ensure the security and traceability of the system, all data interaction records between roadside equipment and the Internet of Vehicles terminal need to be recorded in detail and properly managed. These records include but are not limited to identity authentication results, service request types, processing time, location information, etc. The system collects these records regularly and sends them to the personal account bound to the Internet of Vehicles terminal. Users can view their vehicle driving trajectory, service usage, etc. at any time through third-party terminals such as mobile APP and web platforms, which enhances user experience and transparency.

[0052] In some embodiments, the highway vehicle network identity authentication system may include multiple functional modules composed of computer program segments. The computer programs of each program segment in the highway vehicle network identity authentication system may be stored in a memory of a computer device and executed by at least one processor to perform (see Figure 1 Description) Functionality for vehicle-to-vehicle authentication on highways.
