Automotive Onboard Device Authentication via Optical Code Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex and error-prone registration processes for motor vehicle users, particularly in Connected Car systems, lead to customer loss and increased support costs due to the need for manual entry of security codes and physical elements, resulting in decreased market acceptance and increased complexity.
Innovation Solution
A method for authenticating user authorization in motor vehicles involves sending a request signal for an authentication code to a computer, which is then provided to an onboard device, allowing for direct authentication within the vehicle, using a two-dimensional matrix code that can be recorded and transferred via a mobile device, reducing manual input and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual entry of security codes and physical elements is used in registration processes, then authentication security is maintained, but user effort and error rate increase
Solution Approach 1:
The patent replaces manual mechanical entry of security codes with an automated optical recognition system. The onboard device captures images of security codes displayed on external devices, and an recognition unit automatically extracts and processes the code information, eliminating the need for manual typing while maintaining security verification.
Solution Approach 2:
The patent introduces an onboard device as an intermediary between the external display device and the registration system. This device serves as a mediator that automatically captures, transmits, and processes security code information, bridging the gap between visual display and system verification without requiring direct user interaction.
2Reliability
If manual entry of security codes is required, then authentication verification is achieved, but registration time and complexity increase
Solution Approach 1:
The automated optical recognition system replaces the time-consuming manual entry process. The onboard device's image capture unit quickly photographs the security code, and the recognition unit instantly processes the information, reducing registration time from multiple minutes of manual input to a few seconds of automated processing.
Solution Approach 2:
The system performs preliminary actions by pre-configuring the onboard device with camera capabilities and recognition algorithms before the registration process begins. This preparation allows the device to immediately capture and process security codes without requiring setup or configuration during the actual registration, thereby reducing overall registration time.
3Reliability
If physical elements like key rings and scratchcards are used, then security code distribution is achieved, but device complexity and support costs increase
Solution Approach 1:
The patent extracts the security code distribution function from physical elements (key rings, scratchcards) and transfers it to a digital display system. Security codes are now generated and displayed electronically on external devices, eliminating the need for physical code carriers and reducing system complexity while maintaining secure distribution.
Solution Approach 2:
Instead of using physical security code carriers, the system creates digital copies of security codes that are displayed on screens. The onboard device captures these digital displays through imaging, effectively copying the code information from the display to the vehicle system without requiring physical intermediaries.
4Reliability
If manual re-entry of codes is required, then authentication is completed, but error rate and support expenses increase
Solution Approach 1:
The automated recognition system replaces manual code transcription with optical character recognition. The system captures the security code as an image and uses pattern recognition algorithms to automatically extract and verify the code, eliminating human errors such as misreading, miswriting, or transposition mistakes that occur during manual entry.
Solution Approach 2:
The system implements feedback mechanisms where the recognition unit verifies the captured code against expected formats and validates the authentication process. If the captured code is unclear or invalid, the system can request recapture, providing immediate feedback that prevents erroneous authentication attempts and reduces support expenses.
