Convenient anonymous car moving system and method based on NFC and two-dimensional code

Abstract

The invention discloses a convenient anonymous car moving system and method, and belongs to the technical field of intelligent traffic. The system comprises a vehicle sticker card physical label with an NFC chip and a server background. And the vehicle owner binds the license plate number, the telephone number and the tag ID in advance. When other people need to move the vehicle, the server can be triggered to initiate an anonymous call only by touching the NFC area of the label or scanning the two-dimensional code on the label to input the license plate through a mobile phone. The server serves as an intermediate party, calls mobile phones of a requester and a vehicle owner at the same time and bridges a call, and real numbers of the requester and the vehicle owner are hidden in the process. Through an NFC + two-dimensional code double-trigger mode, extremely convenient operation experience is provided, the problem of mobile phone number leakage caused by a traditional car moving mode is fundamentally solved by using a centralized anonymous communication technology, and the privacy security of a car owner is protected.

Description

Technical Field

[0001] This invention relates to the field of intelligent transportation and communication technology, and in particular to a convenient and anonymous vehicle relocation system and method that effectively protects personal privacy for temporary vehicle contact. Background Technology

[0002] With the rapid increase in the number of motor vehicles, "moving a car" has become a frequent need in urban life. Currently, the mainstream method is to place a sign with the owner's mobile phone number on the windshield. This method poses a significant risk of privacy breaches: phone numbers are sensitive personal information, and exposing them to strangers could lead to harassing calls, scams, and marketing campaigns. Furthermore, paper number plates are prone to wear and tear, easy to forget, and unsightly.

[0003] Existing technologies include several QR code-based car relocation solutions, where users scan the code to contact the car owner through an intermediary platform. However, most of these solutions still require car owners to disclose their phone numbers (e.g., by directly displaying or clicking to dial), or involve cumbersome processes (e.g., requiring both parties to install specific apps), failing to fundamentally resolve the conflict between privacy leaks and convenience. Furthermore, the single QR code scanning method offers a poor user experience in situations with poor mobile network connectivity or low light conditions.

[0004] Therefore, there is an urgent need for a system that can both conveniently trigger vehicle relocation and completely hide the real phone numbers of both parties. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a convenient and anonymous car relocation system and method that is easy to operate and offers strong privacy protection. This system integrates both NFC touch and QR code scanning triggering methods, combined with anonymous communication processing in the server backend, to achieve the effect of "one-click car relocation" while "keeping your phone number confidential."

[0006] The present invention adopts the following technical solution:

[0007] A convenient and anonymous car relocation system mainly includes:

[0008] The physical tag unit consists of a transparent PVC tag sleeve and a built-in vehicle sticker card. The tag sleeve has adhesive backing for secure attachment to the inside of the windshield. The vehicle sticker card is made of cardstock with an NFC chip, printed with a "Scan to Move Car" and system entry QR code, as well as "Touch to Move Car" and NFC prompt icons. The NFC chip contains a globally unique identifier (UID).

[0009] Server backend system: This is the core of the invention, including:

[0010] Database module: Securely stores the binding relationship between vehicle license plate number, vehicle owner's real mobile phone number, and NFC chip UID.

[0011] Communication processing module: responsible for receiving and processing vehicle relocation requests from users' mobile phones.

[0012] Anonymous Call Module: Upon receiving a valid request, this module simultaneously calls both the car owner and the requesting user. Once both parties answer, the system bridges the two lines to enable the call. Throughout the process, the caller ID displayed on both phones is an intermediate number from the system (such as a 95 / 96 or 400 service number), not the other party's real number. After the call ends, the anonymous channel is disabled, thus perfectly protecting the privacy of both parties.

[0013] The beneficial effects of this invention are:

[0014] Ultimate privacy protection: Completely eliminates the direct exposure of mobile phone numbers, fundamentally avoiding the risk of information leakage and harassment caused by moving cars.

[0015] Dual triggering for convenience and efficiency: It supports both NFC "touch to call" and QR code "scan to call," adapting to different users' phone models and usage habits. NFC is especially suitable for scenarios where scanning is inconvenient, such as low light or poor network conditions, providing a superior experience.

[0016] Low cost and easy to promote: Physical labels are inexpensive to produce and durable (PVC sleeves are waterproof and scratch-resistant). Users do not need to install any additional app; they can operate the label using their mobile phone's built-in NFC function or WeChat's QR code scanning function, making the barrier to entry extremely low.

[0017] The system boasts high reliability: anonymous calls are guaranteed by the server-centric system, ensuring stability and reliability, and call records are traceable, thus preventing malicious harassment. Attached Figure Description

[0020] Figure 3 This invention provides a schematic diagram of the process of a third-party user using the anonymous car relocation system. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example:

[0023] After purchasing this car relocation system label, the car owner must first bind it. The owner scans the QR code on the label with their mobile phone to access the binding mini-program or webpage, entering their license plate number and real mobile phone number. Then, following the prompts, the owner brings their phone close to the NFC chip area; after a "beep," the system automatically reads the chip's UID and completes the binding with the car owner's information. Finally, the label is inserted into the PVC sleeve and affixed to the windshield inside the car.

[0024] When other users need to request that the car be moved, there are two ways:

[0025] Method A (Recommended): Take out your NFC-enabled phone (usually just unlock the screen) and tap it directly on the area of ​​the car sticker that says "Touch to Move Car". The phone automatically reads the NFC information and redirects to the browser to send a request to the server. The user may only need to click "Confirm Call" once, and the server will then simultaneously call both the user's and the car owner's phones.

[0026] Method B (Alternative): The user scans the QR code on the vehicle sticker, which redirects to a page displaying "Please enter the license plate number of the vehicle you see" (this can also be automatically filled in via image recognition). After the user enters and confirms, the server's anonymous call process is triggered. Throughout the call, both parties display "Vehicle Relocation Service Hotline 400-XXXXXXX," achieving complete anonymity.

[0027] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
