License Plate Authentication via Vehicle Profile Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic vehicle number plate recognition systems lack robust authentication methods, making them vulnerable to counterfeiting, especially in applications where fraud could significantly impact service reliability, such as payment services.
Innovation Solution
The method involves verifying the location of the authentic vehicle associated with the recognized license plate by using additional information like the vehicle's brand, model, and color, and optionally requiring confirmation from the vehicle's owner through a mobile radio network, ensuring that the authentication occurs in real-time and with multiple security levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed image analysis is performed to detect counterfeit plates, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The authentication process is divided into multiple independent verification stages: initial plate recognition, vehicle characteristic verification (brand, model, color), location verification, and owner confirmation. Each stage operates independently to verify different aspects of authenticity, allowing the system to achieve high detection precision without requiring all verification methods to be simultaneously complex.
Solution Approach 2:
The patent introduces an intermediary authentication server that coordinates between the plate recognition system, vehicle databases, location verification systems, and owner communication channels. This intermediary manages the complexity of multi-source verification by centralizing the coordination logic, allowing individual components to remain relatively simple while achieving comprehensive authentication.
2Reliability
If multiple verification levels are implemented, then reliability is improved, but loss of time increases
Solution Approach 1:
Vehicle characteristics (brand, model, color) and owner contact information are pre-registered in the authentication server database before the authentication process begins. During actual authentication, the system only needs to verify against these pre-stored data, significantly reducing processing time while maintaining multiple verification levels for high reliability.
Solution Approach 2:
The authentication process implements staged verification where critical checks (plate recognition, vehicle characteristics) are performed first in periodic stages. Less critical or optional verifications (owner mobile confirmation) can be performed subsequently or asynchronously, allowing the system to achieve baseline reliability quickly while offering enhanced reliability options that take longer.

AI summary
The prior art provides a number of tools that reliably perform the automatic recognition of vehicle license plates; such cools are generally based on techniques of automatic recognition of images, and in particular on so-called OCR techniques (Optical Character Recognition) which are now cheap enough to find wide application. However, many applications of these methods of license plates recognition suffer from the fact that it is quite easy to counterfeit a plaque. The present invention proposes a method that allows to authenticate the recognition of a license plate through the verification that in the same place of the plate recognition, there is also the simultaneous presence of another object for acknowledgment, more complex to counterfeit and that normally circulates together with the authentic plate which corresponds to recognized plate number.
