AR Payment Authentication via Device-Specific PIN Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared user environments, such as public spaces or ride shares, users face challenges in entering payment credentials securely, as standard PIN pad configurations make it easy for others to detect or infer their PIN numbers.
Innovation Solution
The system generates unique augmented reality payment authentication interfaces for each user in a shared environment, ensuring that payment credentials are not discernible to others, even if they observe the input process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard PIN pad configuration is used, then the device is easy to operate and manufacture, but payment credentials become easily detectable by others in a shared environment
Solution Approach 1:
The patent applies local quality by providing each user with a customized PIN pad configuration where the alphanumeric character mapping is specific to that user's device. This means different parts of the system (different user devices) have different local properties (customized character arrangements), making credentials non-detectable to others while maintaining ease of operation for each individual user.
Solution Approach 2:
The system changes the parameter of character arrangement mapping for each user device. Instead of using a fixed standard PIN pad configuration, the system dynamically assigns different alphanumeric mappings to different devices, thereby changing the security parameter while preserving operational simplicity through automated configuration.
2Object-affected harmful factors
If a customized device-specific interface is implemented, then payment credential security is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by automatically generating and assigning customized alphanumeric mappings to each user device without requiring manual configuration. The device itself receives its unique interface configuration through automated processes, reducing the perceived complexity for users while maintaining high security through device-specific interfaces.
Solution Approach 2:
The patent applies universality by creating a standardized system framework that can serve multiple users with different devices. The same underlying technology platform supports customized interfaces for numerous users simultaneously, reducing overall system complexity through reusable components and standardized protocols despite individual customization.
