In-Vehicle Payment System Using Dynamic Code Table for Secure Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle payment systems face challenges in securely and conveniently generating authorization information, as existing methods expose personal information on screens and require cumbersome input processes, making users uncomfortable and prone to errors.
Innovation Solution
An in-vehicle payment system with an authentication number input device on the steering wheel and a code display device that uses a randomly changing code table, allowing users to input authentication numbers through control keys, generating and recognizing input signals to create secure authorization information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personal information is displayed on the AVNT screen for payment, then payment information can be input, but user privacy is exposed and users feel uncomfortable
Solution Approach 1:
The payment system is segmented into two separate interfaces: a code table display interface for secure code presentation and an authentication number input interface for private input. This segmentation allows the code to be displayed separately from the input process, reducing information exposure while maintaining payment functionality.
Solution Approach 2:
A code table serving as an intermediary element is introduced between the payment system and the user. The code table displays authentication codes in a structured format, acting as a mediator that enables payment verification without directly exposing sensitive personal information on the main screen.
2Reliability
If traditional input methods are used for authentication, then payment can be processed, but the input process is cumbersome and error-prone
Solution Approach 1:
The code table is designed with dynamic characteristics, allowing it to be displayed in various formats and updated with different authentication codes. This dynamic presentation makes it easier for users to locate and input the correct authentication number, reducing input errors while maintaining payment security.
Solution Approach 2:
The authentication code presentation parameters are changed from traditional text input fields to a structured code table format with specific visual characteristics. This parameter change in display format improves user ability to accurately identify and input authentication codes, reducing errors.

AI summary
An in-vehicle payment system and a method for generating authorization information using the same are provided. The in-vehicle payment system includes an authentication number input device including an interface of a vehicle configured to receive an input from a user, and generate and output input signals corresponding to a manipulation pattern of the interface, a code display device configured to display a code table in an array form including a plurality of code values based on received code information on a screen, and an authorization information generator configured to generate the code information and transmit the code information to the code display device, and recognize an authentication number input by the user using the code information and preset matching information to generate authorization information corresponding to the authentication number when the input signals are received from an authentication number input device.
