Description

Technical Field

[0001] The present invention relates to the technical field of ETC, and in particular to a digital safety detection method and system based on OBU equipment. Background Art

[0002] At present, the industry requirement for ETC on-board equipment (OBU) is: "one car, one card, one label", which means that the vehicle on which the equipment is installed must be consistent with the vehicle information submitted by the user when applying for ETC. This prevents users from applying for ETC equipment with vehicle A (small car) and then installing it on vehicle B (large car) for use, thereby evading tolls. To solve this problem, industry specifications require that OBU equipment have an anti-disassembly function, that is, the equipment cannot be disassembled after being pasted and fixed on the vehicle. If it is disassembled, it will trigger the anti-disassembly module on the equipment, thereby triggering the equipment to be automatically disabled. Therefore, existing OBU equipment all have an anti-disassembly switch module, which allows the equipment to be installed on the vehicle through the function of the anti-disassembly switch, so that users cannot disassemble it. The physical principle of the anti-disassembly switch is: the anti-disassembly switch has an elastic structure, and the elastic structure is in a compressed state when the device is pressed tightly. When the device is disassembled, the elastic structure pops up, causing the circuit to be disconnected, thereby changing the circuit state of the device, triggering the device program to automatically set the device to disabled, and its transaction function to an unavailable state, thereby preventing the owner from disassembling the device after installing it. As an on-vehicle device for automatic fee deduction and payment, the OBU device has an anti-disassembly function (physical anti-disassembly), which requires the device to be fixed on a specific vehicle. This prevents users from actively moving the device to other vehicles for use to a certain extent, and also prevents the user's device from being illegally misappropriated and deducted by others, thereby ensuring the financial security of the user's ETC account.

[0003] With the increasing popularity of ETC equipment on the Internet and the popularization of ETC fee deduction scenarios, the above method of ensuring that the user's application vehicle is consistent with the installed vehicle through the anti-disassembly function (physical anti-disassembly) and protecting the user's OBU device from being misappropriated and deducted fees indiscriminately has obvious defects. Many illegals have learned the anti-disassembly principle of OBU equipment through information on the Internet, so they can use external objects to fix and keep the elastic structure of the OBU equipment anti-disassembly switch from bouncing, thereby achieving illegal disassembly and misappropriation of the user's OBU equipment. In addition, some roadside parking lots in the city have mobile ETC fee deduction terminals. After the user parks and leaves, the toll collector holds the mobile ETC fee deduction terminal and deducts the parking fee through the user's OBU device without the user's witness and permission. The existing physical anti-disassembly function of the OBU device can no longer effectively protect the user's OBU device from the use risks. Therefore, designing a solution that can make it more convenient and safe for users to use has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0004] In response to the above defects, an embodiment of the present invention discloses a digital security detection method based on OBU equipment.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0019] It should be noted that the terms "first", "second", "third", "fourth", etc. in the specification and claims of the present invention are used to distinguish different objects rather than to describe a specific order. The terms "including" and "having" in the embodiments of the present invention and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0020] With the increasing popularity of ETC devices on the Internet and the prevalence of ETC fee deduction scenarios, the above method of ensuring that the vehicle applied for by the user is consistent with the installed vehicle through the anti-disassembly function (physical anti-disassembly) and protecting the user's OBU device from being misappropriated and deducted fees indiscriminately has obvious defects. Many illegal persons have learned the anti-disassembly principle of OBU equipment through information on the Internet, so they can use external objects to fix and keep the elastic structure of the OBU device anti-disassembly switch from bouncing, thereby achieving illegal disassembly and misappropriation of the user's OBU device. In addition, some roadside parking lots in the city have mobile ETC fee deduction terminals. After the user parks and leaves, the toll collector holds the mobile ETC fee deduction terminal and deducts the parking fee through the user's OBU device without the user's witness and permission. The existing physical anti-disassembly function of the OBU device can no longer effectively protect the user's OBU device from the use risks. Based on this, the embodiment of the present invention discloses a digital security detection method, system, electronic device and storage medium based on OBU equipment. By matching the device unique identifier of the searched Bluetooth wireless signal with the preset information verification list, the method can quickly determine whether the OBU equipment is within the allowed physical range to control the transaction function of the OBU to be available or unavailable, which makes up for the defects of the existing physical anti-disassembly function of the OBU product and more effectively protects the user's OBU equipment usage safety and financial security. The information verification list contains the physical address information and Bluetooth name of the known vehicle Bluetooth wireless module and the physical address information and Bluetooth name of the mobile phone Bluetooth wireless module. In this process, the OBU device is the leading device, and the identity information of the target device is obtained by listening. There is no need to establish a Bluetooth communication handshake and connection with the target device, which greatly improves the efficiency and reliability of the wireless data security verification of the OBU device; there is no need to agree on a specific communication protocol with the vehicle manufacturer and the mobile phone manufacturer, which greatly improves the universality and scalability of the device.

[0021] Example 1: Please refer to Figure 1 , Figure 1 It is a flow chart of the digital security detection method based on OBU equipment disclosed in the embodiment of the present invention. Among them, the execution subject of the method described in the embodiment of the present invention is an execution subject composed of software and / or hardware, and the execution subject can receive relevant information by wired or / and wireless means, and can send certain instructions. Of course, it can also have certain processing functions and storage functions. The execution subject can control multiple devices, such as a remote physical server or cloud server and related software, or it can be a local host or server and related software that performs related operations on a device placed somewhere. In some scenarios, multiple storage devices can also be controlled, and the storage devices can be placed in the same place or different places as the devices. For example Figure 1 As shown, the digital security detection method based on the OBU device comprises the following steps: S101: After the OBU device is started, the Bluetooth communication module inside the OBU device is started to search for all Bluetooth wireless signals in the current environment; S102: Receive all searched Bluetooth wireless signals, obtain the device unique identifier in the Bluetooth wireless signal, and match the obtained device unique identifier with a preset information verification list. If they match, the verification is successful and the transaction function of the OBU device is set to an available state. If they do not match, the verification fails and the transaction function of the OBU device is set to an unavailable state. The information verification list includes the device unique identifier of the vehicle Bluetooth wireless module and the device unique identifier of the mobile phone Bluetooth wireless module.

[0022] The unique device identifier here may be device address information or a Bluetooth name, which are information that can be used to identify the device; however, it is not limited to these two forms of information, and may also be other types of information.

[0023] The design logic of the embodiment of the present invention is digital anti-disassembly. After the user connects to the OBU device through Bluetooth communication of an intelligent terminal (such as an APP, a small program, etc.), the physical address or Bluetooth name of the trusted vehicle and the trusted mobile phone is set to the OBU device to form an information verification list in the OBU device. When the OBU device is started, it synchronously searches for wireless signals (such as Bluetooth signals) emitted by all nearby vehicles, user mobile phones and other devices, and parses the acquired wireless signals to obtain the physical address information or Bluetooth name of the target device, and further verifies the physical address information and Bluetooth name of the target device with the information verification list of the OBU device. When the verification is passed, it proves that the OBU device is currently being used within the close range of the vehicle trusted by the user and the person trusted by the user, so the transaction function of the OBU device is set to an available state. When the inspection fails, it means that the OBU device is not currently being used within the close range of the vehicle trusted by the user or the person trusted by the user, so the transaction function of the OBU device is set to an unavailable state.

[0024] The digital security detection method (digital anti-dismantling) on ​​the OBU device can ensure that the OBU device is within the close range of the vehicle approved by the user and the user approved by the user during the transaction, thereby solving the security problems of dismantling, misappropriation and random deductions that cannot be solved by the physical anti-dismantling of the existing OBU equipment.

[0025] In terms of device form, the device can be designed to be used only when both physical anti-disassembly and digital anti-disassembly are met at the same time (in fact, it can also support users to use physical anti-disassembly or digital anti-disassembly separately). In the specific implementation, the mixed use of physical anti-disassembly and digital anti-disassembly can solve the following problems: Security: First, other illegal users cannot use the user's OBU device to other vehicles by exploiting the physical anti-disassembly loopholes of the OBU device. Second, because the digital anti-disassembly will verify the consistency of the OBU device with the vehicle and the user's mobile phone, after the user leaves the vehicle (that is, the user's mobile phone leaves the use range of the OBU device), even if the OBU device is still installed on the vehicle, the user's OBU device is not afraid of other vehicle users using and trading without authorization (for example, in the scenario of taxi handover, another vehicle user uses the OBU device to pass and deduct the user's fee), and is not afraid of the mobile ETC deduction terminal deducting fees without the user's witness. Convenience: Users can choose either a fixed installation mode or a non-fixed installation mode for easy use by users. The embodiment of the present invention comprehensively considers a variety of usage scenarios, making it more in line with actual needs.

[0026] The equipment feature of the embodiment of the present invention is that the digital anti-disassembly is that the wireless communication verification is controlled and completed by the OBU itself, and the vehicle or mobile phone cooperation is not required. The OBU has a variety of mixed digital anti-disassembly verification (verifying the vehicle and verifying the user's mobile phone) and physical anti-disassembly verification. Digital anti-disassembly verification, the embodiment of the present invention mainly verifies Bluetooth, that is, OBU verifies the vehicle Bluetooth and the mobile phone Bluetooth to identify whether the OBU is consistent with the person-device-vehicle. This can solve the versatility of the equipment, that is, it is not necessary to dock with the vehicle main engine factory, and the equipment can be applied to the existing stock of vehicles (only the mobile phone and vehicle Bluetooth need to be kept open). When the equipment performs the person-vehicle Bluetooth verification, the OBU does not need to establish a handshake and connection of Bluetooth communication with the target device, but the OBU device actively listens and collects the Bluetooth signals sent by other devices, and then the OBU can complete the analysis and verification autonomously, so when the user's mobile phone Bluetooth and the vehicle Bluetooth are occupied by other devices, the whole inspection process can still be completed, greatly improving the efficiency and success rate of identification.

[0027] When conducting digital inspections on the consistency between devices and vehicles, more existing OBU devices need to be vehicle-oriented. When conducting specific designs, the devices must agree on specific communication protocols with specific vehicles, and technically require the cooperation of the host manufacturer. Technical implementation is difficult. In a vehicle-oriented communication system, the device needs to agree on a specific communication protocol with a specific vehicle. This usually means that during the design phase, developers need to work closely with the host manufacturer to ensure that the device can communicate with the vehicle in the intended manner. The design and implementation of this communication protocol often involves an in-depth understanding and application of the underlying hardware, software, and communication standards, and is relatively difficult to implement. In particular, OBU devices not only have to adapt to the private communication protocols of many vehicle host manufacturers, and the development workload is huge, but they cannot be used in the large number of vehicles on the market that cannot upgrade their systems.

[0028] In actual implementation, most users would not think of using Bluetooth modules for identity authentication. Bluetooth modules are generally used as a means of communication transmission. By designing a user-friendly interactive interface and providing real-time identity authentication feedback, the user experience is optimized. This innovation makes the Bluetooth identity authentication function easier to understand and use, thereby improving user satisfaction and trust.

[0029] Another main reason why Bluetooth communication signals can be used as identity authentication here is that comprehensive verification has been carried out in the early stage. That is, when the OBU equipment is issued and activated in the early stage, comprehensive verification can realize accurate identification of user identity and recording of Bluetooth signals. Moreover, not only a certain information is verified here, but two Bluetooth signals, vehicle and mobile phone, are involved. Moreover, the scenario in which the action occurs is also relatively specific, which makes it possible to use it as a comprehensive identity verification.

[0030] The solution of the embodiment of the present invention does not require the OBU device to establish communication with the target device, but only requires the OBU device to autonomously listen, analyze and verify. It can improve the efficiency and success rate of recognition when the user's mobile phone or vehicle Bluetooth is occupied by other devices.

[0031] More preferably, the digital safety detection is enabled only when the OBU device is started to enter the working state, and the transaction function of the OBU device in the current working cycle is set to an available or unavailable state according to the digital safety detection result. When the OBU device enters sleep or is turned off, and is started to the working state next time, the OBU enables the digital safety detection again, and sets the transaction function of the OBU device in the next working cycle to an available or unavailable state. This allows the OBU device to perform digital safety detection without a continuous cycle, thereby reducing the power consumption of the device.

[0032] More preferably, the information verification list includes primary verification information and secondary verification information, the primary verification information includes the physical address information and Bluetooth name of the vehicle's Bluetooth wireless module, and the secondary verification information includes the physical address information and Bluetooth name of the mobile phone's Bluetooth wireless module; like Figure 2 As shown, the receiving of all the Bluetooth wireless signals searched, and matching the physical address information and Bluetooth name in the obtained Bluetooth wireless signals with the preset information verification list, if they match, the verification is passed and the transaction function of the OBU device is set to an available state, if they do not match, the verification fails and the transaction function of the OBU device is set to an unavailable state, and the inspection result is broadcast and prompted to the user, including: S1021: Receive all searched Bluetooth wireless signals; S1022: Match the physical address information or Bluetooth name in the acquired Bluetooth wireless signal with the first-level verification information in the preset information verification list. If they are not consistent, it is determined that the two do not match, the verification fails, and a notification and prompt are given to the user; if the address information matches the first-level verification information, the next step is executed; S1023: Match the physical address information and Bluetooth name in the obtained Bluetooth wireless signal with the secondary verification information in the preset information verification list. If they are inconsistent, it is determined that the two do not match and the verification fails. The user is notified and prompted. If the Bluetooth address information matches the secondary verification information, the verification passes.

[0033] The embodiment of the present invention performs double verification of Bluetooth wireless signals by establishing primary and secondary verification information, effectively preventing unauthorized Bluetooth devices from accessing and enhancing the security of communications. The hierarchical verification mechanism can more accurately identify legitimate Bluetooth devices, reduce false positives and false negatives, improve the accuracy of verification, and can improve the accuracy of verification, because there is a verification logic that under normal circumstances, the vehicle Bluetooth signal obtained is one, while the mobile phone Bluetooth signal may be multiple, so verifying the vehicle Bluetooth signal first can improve the overall comparison efficiency.

[0034] When verification fails, the device can promptly broadcast and prompt the user, reminding the user whether the device is currently in a tradable or non-tradable state, thereby optimizing the user experience. The first-level verification information includes the physical address information and Bluetooth name of the vehicle's Bluetooth wireless module, which is an important identifier of the vehicle's identity. Through the first-level verification, the system can quickly filter out Bluetooth signals that match the vehicle's Bluetooth module, exclude most irrelevant signals, and improve verification efficiency. The second-level verification information includes the physical address information and Bluetooth name of the mobile phone's Bluetooth wireless module, which is an important identifier of the user's identity. After passing the first-level verification, the system further matches the second-level verification information to ensure that the connected Bluetooth device is not only related to the vehicle, but also to the specific user, thereby achieving double security verification.

[0035] More preferably, Figure 3 As shown, the receiving of all searched Bluetooth wireless signals and matching the Bluetooth address information in the obtained Bluetooth wireless signals with a preset information verification list, if they match, the verification is successful, if they do not match, the verification fails, including: S102a: Receive all searched Bluetooth wireless signals, where the Bluetooth wireless signals include Bluetooth address information and signal strength information; S102b: matching the signal strength information in the Bluetooth wireless signal with a set strength threshold, and if the signal strength information is within the set strength threshold range, determining all Bluetooth address information within the strength threshold range; S102c: Match all Bluetooth address information within the strength threshold range with the preset information verification list. If they match, the verification is successful. If they do not match, the verification fails, and the corresponding security detection results are sent to the corresponding users.

[0036] By introducing signal strength information as a verification condition, the embodiment of the present invention can more accurately screen out Bluetooth devices that are close to the vehicle or user, reducing verification failures caused by long-distance signal interference or false alarms. The setting of the signal strength threshold effectively limits the range of accessible Bluetooth devices, further enhances the security of communications, and prevents potential security threats. By screening the signal strength, the system can reduce unnecessary verification operations, thereby optimizing the utilization of computing resources and network resources.

[0037] The system screens the received Bluetooth wireless signals according to the set strength threshold, and only retains the Bluetooth address information within the strength threshold range. This step effectively excludes Bluetooth devices that are far away or have weak signals, improving the accuracy and efficiency of verification.

[0038] After passing the signal strength screening, the system further matches the Bluetooth address information within the strength threshold range with the preset information verification list. This double verification mechanism ensures that only legitimate and close Bluetooth devices can pass the verification, further enhancing the security of communication. When the verification fails, the system can immediately send the security detection results to the user to remind the user that the current situation may have security risks. This instant feedback mechanism helps users take corresponding measures in a timely manner.

[0039] More preferably, Figure 4 As shown, the digital security detection method further includes: S100a: After the user completes the activation of the OBU device through the smart terminal, the installation method selected by the user is received. If the installation method is a non-fixed installation method, the vehicle Bluetooth information and the mobile phone Bluetooth information are obtained through the smart terminal, and the information verification list of the corresponding OBU device is updated according to the vehicle Bluetooth information and the mobile phone Bluetooth information; S100b: If the installation mode is a fixed installation mode, obtaining image information of the OBU device after fixed installation through the intelligent terminal; S100c: Analyze the image information to determine the spatial installation position of the OBU device, and determine the position information of the spatial installation position to each key point in the corresponding vehicle according to the vehicle model information; S100d: Receive Bluetooth strength information of the user's mobile phone when the mobile phone is at each key point, determine a corresponding Bluetooth strength interval based on the Bluetooth strength information of the mobile phone at each key point, and store the Bluetooth strength interval and the position of the key point, wherein the position of the key point is used to characterize the user's riding position.

[0040] The method of the embodiment of the present invention supports both non-fixed installation and fixed installation, meets the installation requirements of different users, and improves the flexibility of installation. For the non-fixed installation method, the vehicle Bluetooth information and the mobile phone Bluetooth information are obtained through the intelligent terminal, and the information verification list of the OBU device is updated, which enhances the accuracy of information verification and improves the security of communication. When the user chooses the non-fixed installation method, the system can quickly obtain the vehicle Bluetooth information and the mobile phone Bluetooth information through the intelligent terminal, and automatically update the information verification list of the OBU device. This step simplifies the installation process and improves the convenience of installation. The update operation of the information verification list ensures that the OBU device can identify and verify the Bluetooth devices related to the vehicle and the user, effectively preventing unauthorized access.

[0041] For fixed installation, by collecting the installation location of the OBU device, vehicle model information, and the Bluetooth strength information of the user's mobile phone at various key points, the personalized Bluetooth strength range is set, which is helpful for subsequent safety verification and communication management. This method takes into account the user's riding position and provides users with more personalized location verification by collecting and analyzing Bluetooth strength information; for example, the Bluetooth strength of the user in the driver's seat, the co-pilot seat, and the back seat will be different, so the location analysis can be performed based on the above differences.

[0042] For users who choose fixed installation, the system collects the image information of the OBU device and analyzes its spatial installation position, and combines the vehicle model information to determine the location information of key points. This step ensures the accurate installation of the OBU device and provides a basis for subsequent position judgment.

[0043] By collecting the Bluetooth strength information of the user's mobile phone at each key point, the system can determine the corresponding Bluetooth strength range and store this information with the location of the key point. This step realizes the setting of personalized Bluetooth strength range, which helps the system to accurately judge the user's location based on Bluetooth strength information during subsequent communication.

[0044] The method takes into account the user's riding position. By collecting and analyzing Bluetooth strength information, the system can provide users with more personalized analysis services. For example, when in different positions in the vehicle, the system can automatically adjust the communication parameters according to the Bluetooth strength information to ensure the stability and quality of communication.

[0045] More preferably, the Bluetooth wireless signal includes Bluetooth address information and signal strength information; the digital security detection method further includes: The actual location information corresponding to each mobile phone is determined based on the acquired signal strength information and the stored Bluetooth strength interval and the location of the key points. If the actual location information of the owner's mobile phone is the driving position, it is determined that the owner is currently in the owner's driving mode, and the monitored mobile phone Bluetooth signal is not counted; If the actual location information of the owner's mobile phone is not in the driving position, it is determined that the owner is in the riding mode, and the detected mobile phone Bluetooth signals are counted. When the mobile phone Bluetooth signals of the non-owner's mobile phone reach the set number, the information verification list is updated according to the mobile phone Bluetooth signals of the non-owner's mobile phone; The transmission power of the Bluetooth module is configured to be 0dBm or -6dBm.

[0046] In the code for initializing the Bluetooth module, call the corresponding macro definition function to set the transmit power. For example, call the HCI_EXT_SetTxPowerCmd(xx) function in the SimpleBLEPeripheral_Init function, where the xx parameter is the required transmit power level (such as LL_EXT_TX_POWER_0_DBM corresponds to 0dBm), and the level adjustment is achieved in the above way.

[0047] The system collects and analyzes Bluetooth signal strength information, combines it with preset Bluetooth strength ranges and location information of key points, and can accurately determine the location of the owner and passengers.

[0048] When the system determines that the owner's mobile phone is in the driver's seat, it automatically turns off the Bluetooth signal statistics function, because the driver is in the driving seat, which means he is the user. The Bluetooth signals from the co-pilot or back seat are passengers. In this way, it can be determined that under normal circumstances, there is no need to add these signals from the co-pilot to the verification list.

[0049] When the owner is in riding mode, the system counts the detected mobile phone Bluetooth signals and updates the information verification list in a timely manner according to the number of Bluetooth signals from non-owner phones. This mechanism ensures that only phones that frequently interact with the vehicle can be included in the information verification list, improving the accuracy and efficiency of information verification.

[0050] By configuring the Bluetooth module's transmit power to 0dBm or -6dBm, the system reduces energy consumption and interference while ensuring Bluetooth signal coverage. This configuration helps extend the life of the Bluetooth module and reduce interference with other electronic devices.

[0051] More preferably, the digital security detection method further includes: The corresponding vibration parameters are obtained by a vibration module arranged at the OBU device, and if the vibration parameters meet the set disassembly conditions, an alarm record is made; The digital security detection method further includes: Determine the Bluetooth verification results within a period of time. If all Bluetooth verification results within the period of time are passed, obtain the non-owner's mobile phone Bluetooth signal that appears in each Bluetooth verification result, and update the information verification list according to the non-owner's mobile phone Bluetooth signal.

[0052] The embodiment of the present invention monitors the vibration parameters of the OBU device through the vibration module, and the system can timely discover and record possible disassembly behaviors, thereby preventing the OBU device from being illegally disassembled or tampered with, thereby improving the safety of the OBU device.

[0053] The set disassembly conditions here specifically refer to one or more specific vibration modes, which are usually associated with illegal disassembly or tampering with OBU equipment. For example, these specific vibration modes may include: Vibration frequency: When illegally disassembling, the OBU equipment may experience vibrations of a specific frequency, which is different from the vibration frequency during normal driving or operation. The system can preset one or more such frequencies as conditions for triggering alarms. Vibration amplitude: Illegal disassembly is often accompanied by a large vibration amplitude, especially when violent disassembly is performed using tools. Therefore, setting a reasonable vibration amplitude threshold is also an effective means of detecting illegal disassembly. Vibration duration: Illegal disassembly behavior usually takes a certain amount of time to complete, which means that the vibration may last for a period of time. The system can monitor the duration of the vibration and compare it with the preset threshold to determine whether there is illegal disassembly behavior. Vibration pattern: Certain specific vibration patterns may be highly correlated with illegal disassembly behavior. For example, intermittent strong vibrations may indicate that someone is trying to disassemble the OBU device with tools. The system can identify these specific vibration patterns by analyzing vibration data. Once the vibration parameters meet any one or more of the above set disassembly conditions, the system will immediately record an alarm.

[0054] When the scheme of the embodiment of the present invention is implemented, data information of each point on the mobile line can be obtained, such as obtaining Bluetooth verification results at various time points on a section of highway, and storing information on the Bluetooth verification results. The above method can be used to determine the credibility of the user identity.

The information verification list contains the device address information of the known vehicle Bluetooth wireless module and the mobile phone Bluetooth wireless module, and the OBU device is the leading device in this process, and there is no need to agree on a specific communication protocol with the vehicle manufacturer and the mobile phone manufacturer, which greatly improves the convenience and scalability of the device.
