Description

Technical Field

[0001] The invention relates to the field of taximeters, and in particular to an electronic lead seal for a taximeter. Background Art

[0002] Currently, in the taxi industry, many taximeters use lead seals as a means to prevent illegal tampering with the device's internal software parameters or electrical circuits. This is achieved by applying a physical closure device (such as a metal wire or plastic seal) to the taximeter that cannot be easily broken. Once the lead seal is broken, it can be clearly detected, thus ensuring the integrity of the taximeter. This traditional method is widely used to ensure the security and accuracy of taximeter parameters, especially when it is necessary to comply with laws, regulations and industry standards.

[0003] However, the traditional lead seal method has obvious shortcomings in the application of taxi meters: (1) Every time the meter parameters need to be adjusted (such as updating the rate, correcting the starting value, etc.), the lead seal must be removed first, which not only increases the workload but also easily causes the lead seal to be damaged. Frequent operation may also affect the long-term reliability of the equipment. (2) Due to its physical properties, traditional lead seals cannot provide real-time security status feedback. This means that even if the lead seal is damaged, it can only be discovered during inspection, and it is impossible to respond to potential security threats in a timely manner. (3) For large-scale taxi fleets, the one-by-one operation method is extremely inefficient and difficult to meet the needs of rapid response in modern traffic management. Each parameter update requires the presence of technicians, which increases operating costs and time consumption. (4) Although physical damage can be detected, traditional lead seals are difficult to prevent internal tampering. For example, technicians may accidentally or intentionally change key parameters when performing legitimate maintenance, and these behaviors are difficult to trace.

[0004] In summary, although the traditional lead sealing method can protect the integrity of taxi meters to a certain extent, it has many shortcomings in terms of operational convenience, real-time feedback, efficiency, safety and compliance. In order to meet these challenges, a more efficient, convenient and safe solution is urgently needed to adapt to the rapid development needs of the modern taxi industry. Summary of the invention

[0005] In view of the above-mentioned technical deficiencies, the technical problem to be solved by the present invention is to provide an electronic seal for a taxi meter, aiming to solve the problems of the traditional sealing method in terms of operational convenience, real-time feedback, efficiency and safety.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a taxi meter electronic seal, comprising: a collection module, an encryption chip module, a communication module, a user interface module and a remote control platform; The encryption chip module is installed on the target device and a security key is preset. The public key and device ID of each device are uploaded to the remote control platform to complete the device registration. The collection module extracts location and timestamp information from the GPS module and other sensors of the taxi, and synchronizes it to the remote control platform through the communication module for analysis and identification of changing trends in peak hours, specific areas and operation modes. The remote control platform automatically generates parameter optimization suggestions based on historical analysis results and pushes them to the administrator through the user interface module. The administrator sends a parameter adjustment request to the remote control platform through the user interface module. At the same time, the remote control platform verifies the identity of the administrator and the device, and confirms whether the parameter adjustment is authorized. After receiving the new parameter configuration file, the target device completes the parameter update and returns to the protected state.

[0007] Furthermore, the administrator sends a parameter adjustment request to the remote control platform through the user interface module; at the same time, the remote control platform verifies the identity of the administrator and the device, and confirms whether the parameter adjustment is authorized, including: The administrator logs in to the remote control platform through the user interface module. After the remote control platform verifies the administrator's identity through multi-factor authentication, it verifies the administrator's authority to ensure that the administrator has the right to initiate parameter adjustment requests; The administrator uploads a configuration file containing new parameter settings, and the administrator digitally signs the configuration file using the administrator's private key. The remote control platform pre-checks the new parameters in the configuration file to ensure that they comply with laws, regulations and industry standards. If the configuration file fails the pre-verification, the update request will be rejected and the administrator will be notified to correct the error; If the configuration file passes the pre-verification, the remote control platform generates a temporary access key according to the pre-set security policy, and the remote control platform sends the configuration file and the temporary access key to the target device through the communication module; After receiving the temporary access key, the target device verifies the validity of the temporary access key.

[0008] Furthermore, it also includes: The remote control platform directly and automatically generates a configuration file containing new parameters and digitally signs it; The remote control platform generates a temporary access key according to a pre-set security policy, and the remote control platform sends the configuration file and the temporary access key to the target device through the communication module; After receiving the temporary access key, the target device verifies the validity of the temporary access key.

[0009] Furthermore, the remote control platform generates a temporary access key according to a preset security policy including: The remote control platform selects all registered and online target devices that need to update parameters, and generates a unique one-time token for each selected device; According to the preset security policy, the remote control platform generates a random temporary access key and encrypts the temporary access key using the public key registered and uploaded by the target device; The validity period of the temporary access key is limited to a set time window. After the time window has expired, the temporary access key will automatically become invalid. The remote control platform digitally signs the temporary access key and device ID, timestamp, and one-time token; A data packet containing an encrypted and signed temporary access key, a signed device ID, a timestamp, and a one-time token is sent to the target device through the communication module. At the same time, the remote control platform records the log information of this operation for auditing.

[0010] Further, after receiving the data packet sent from the remote control platform, the target device uses the public key of the remote control platform to verify the digital signature in the data packet; If the verification is successful, the encryption chip also uses the device private key to decrypt the encrypted temporary access key; If decryption is successful, the temporary access key is valid; If the decryption fails, the temporary access key is invalid and the abnormality is reported to the remote control platform.

[0011] Furthermore, after decryption, if the administrator manually uploads the configuration file, the administrator's public key is used to verify the digital signature of the configuration file; if the remote control platform automatically generates the configuration file, the remote control platform's public key is used to verify the digital signature of the configuration file; If the signature verification fails, the abnormal situation is reported to the remote control platform; If the signature verification is successful, the encryption chip module parses the parameters in the configuration file and verifies again whether each parameter complies with the predefined legal range or rules; If any parameter exceeds the allowed range, the update operation will be rejected and the abnormal situation will be reported to the remote control platform; Parameter updates are performed only when all parameters pass local verification; After the parameter update is completed, the encryption chip module automatically returns to the protected state.

[0012] Furthermore, the remote control platform regularly reviews the log information of all devices to check whether there are any unauthorized operations or parameter settings that do not comply with regulations; If any abnormal situation is found, the remote control platform will immediately trigger the alarm mechanism and notify relevant personnel to take action.

[0013] Furthermore, when the parameters are updated, the remote control platform sends a notification to the driver through the user interface module, explaining the new billing rules and their basis to ensure service transparency.

[0014] The beneficial effects of the present invention are: 1. The present invention avoids the physical disassembly and assembly of traditional lead seals through electronic authorization and remote management, simplifies the maintenance process, reduces labor costs, and the system supports remote batch parameter updates, which significantly improves management efficiency; 2. The present invention adopts a double verification mechanism and digital signature technology to ensure the security and integrity of parameter updates. The real-time monitoring and alarm mechanism can respond to abnormal situations in a timely manner. All operations are recorded in detail to facilitate review and troubleshooting. 3. The present invention automatically saves parameter snapshots to ensure that operations are traceable and comply with legal and regulatory requirements. Strict authority management prevents internal personnel from abusing authority, reduces operating costs and extends equipment life by reducing on-site maintenance requirements.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0017] 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.

[0018] like Figure 1As shown, this embodiment provides a taxi meter electronic seal including: a collection module, an encryption chip module, a communication module, a user interface module and a remote control platform; specifically, the technician installs a meter with an encryption chip module for each taxi; each meter generates a pair of asymmetric keys, and uploads the device public key and device ID to the remote control platform to complete the device registration; the technician ensures that the public key of the remote control platform is preset in the secure storage area of ​​each meter for subsequent data packet verification; the collection module extracts location and timestamp information from the GPS module and other sensors of the taxi, and synchronizes them to the remote control platform through the communication module; the remote control platform receives these data in real time for analyzing the changing trends of peak hours, specific areas and operating modes; specifically, the remote control platform analyzes based on historical data and real-time data to identify the changing trends of peak hours, specific areas and operating modes; based on these analysis results, the remote control platform automatically generates parameter optimization suggestions, and pushes them to the administrator through the user interface module to help him make reasonable parameter adjustment decisions.

[0019] Specifically, according to the actual situation, choose to use the administrator manual update mode or the remote control platform automatic update mode to update the parameters as follows: For example, if a taxi meter fails, resulting in inaccurate billing, the administrator manual update mode is selected. At this time, the administrator logs in to the remote control platform through the user interface module, and after multi-factor identity authentication (such as password + SMS verification code), confirms his authority to ensure that he has the right to initiate parameter adjustment requests; the administrator prepares a new parameter setting configuration file based on the parameter optimization suggestions pushed by the remote control platform, including peak hour rates, specific area surcharges, etc.; the administrator uses his own private key to digitally sign the configuration file to ensure the authenticity and integrity of the file; the administrator uploads the configuration file to the remote control platform through the user interface module; the remote control platform pre-checks the new parameters in the received configuration file to ensure that it complies with laws, regulations and industry standards; if the configuration file fails the pre-check, the update request is rejected and the administrator is notified to correct the error; if it passes, proceed to the next step.

[0020] For example, if the city traffic management department decides to adjust the peak-hour fares of all taxis in the city during holidays, the remote control platform automatic update mode will be selected. At this time, the remote control platform automatically generates new parameter settings based on the data analysis results and packages them into a configuration file; after the configuration file is digitally signed, a temporary access key is generated without the need for administrator intervention.

[0021] Furthermore, the remote control platform selects all registered and online target devices and generates a unique one-time token for each selected device; according to the preset security policy, the remote control platform generates a random temporary access key and encrypts the temporary access key with the public key registered and uploaded by the target device; the validity period of the temporary access key is limited to a 10-minute time window and automatically expires after this time window; the remote control platform digitally signs the temporary access key, device ID, timestamp and one-time token; sends the data packet containing the encrypted and signed temporary access key and configuration file to the target device through the communication module; at the same time, the remote control platform records the log information of this operation for auditing; after the target device receives the data packet, it uses the previously known and trusted public key of the remote control platform to verify the digital signature in the data packet to ensure the authenticity and integrity of the data packet; if the verification is successful, proceed to the next step; if the verification fails, refuse to process and report the abnormality to the remote control platform; use the device private key to decrypt the encrypted temporary access key; if the decryption is successful, it means that the temporary access key is valid; if the decryption is not successful, it means that the temporary access key is invalid, and the abnormality is reported to the remote control platform.

[0022] Specifically, after decryption, if the administrator manually uploads the configuration file, the administrator's public key is used; if the remote control platform automatically generates the configuration file, the public key of the remote control platform verifies the digital signature of the configuration file to ensure the authenticity and integrity of the file: if the signature verification fails, further operations are rejected and the abnormality is reported to the remote control platform; if the signature verification is successful, the encryption chip module parses the parameters in the configuration file and checks again whether each parameter complies with the predefined legal range or rules; if any parameter exceeds the allowable range, the update operation is rejected and the abnormality is reported to the remote control platform; if all parameters pass the local verification, the parameters are updated; after the parameter update is completed, the encryption chip module automatically returns to the protected state; at the same time, the remote control platform notifies the driver through the user interface module, explaining the new billing rules and their basis to ensure service transparency; at the same time, the remote control platform also provides necessary notifications to passengers to ensure service transparency not only for drivers but also for passengers.

[0023] Preferably, the remote control platform regularly reviews the log information of all devices to check whether there are unauthorized operations or parameter settings that do not comply with regulations; if any abnormal situation is found, the alarm mechanism is immediately triggered to notify relevant personnel to take action.

[0024] Through the above embodiments, it can be seen that this embodiment ensures the security and accuracy of parameter updates through a series of security measures and technical means. The entire process from device registration, data collection and analysis, parameter optimization suggestion generation, parameter adjustment request initiation, temporary access key generation and distribution, target device reception and verification, parameter parsing and verification, parameter update to the final log review and alarm mechanism forms a complete closed-loop management to ensure that each parameter adjustment is legal, transparent and safe.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
