Secure Payment Token Reuse for Online Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure payment transaction devices lack flexibility and security enhancements, particularly in online digital money systems, as they are typically issued for offline use and require dedicated hardware for online authentication.
Innovation Solution
A secure payment transaction device is enhanced with a data updating unit to add online authentication information, enabling reuse in online digital money systems without altering its security certification, by registering it as a secondary authentication means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If secure payment transaction devices are issued for offline use only, then security certification is maintained, but flexibility and adaptability to online systems deteriorates
Solution Approach 1:
The secure payment transaction device is designed to perform multiple functions: it can operate in offline monetary value token systems as originally intended, and simultaneously function in online digital money systems after receiving online authentication information through the updating unit. This multi-functionality resolves the contradiction by making the device universal across different system types without compromising its core security properties.
Solution Approach 2:
The device transitions from a static offline-only configuration to a dynamic state where it can be remotely updated with online authentication information. The updating unit enables the device to adapt its functionality dynamically based on system requirements, allowing it to switch between offline and online operational modes while maintaining security certification.
2Reliability
If dedicated hardware is created for online authentication, then security is improved, but device complexity and cost increases
Solution Approach 1:
Instead of creating separate dedicated hardware for online authentication, the invention makes the existing secure payment transaction device universal by enabling it to handle both offline monetary value token operations and online digital money authentication. The updating unit adds online functionality to the existing hardware, avoiding the need for additional dedicated components.
Solution Approach 2:
The invention merges the offline secure token operations and online authentication functions into a single device. The updating unit combines the existing secure hardware infrastructure with online authentication capabilities, eliminating the need for separate dedicated hardware and reducing overall system complexity.
3Adaptability or versatility
If online authentication information is added via updating unit, then flexibility and adaptability improve, but security may be compromised
Solution Approach 1:
The device undergoes preliminary security certification for offline operations before being deployed. The updating unit then adds online authentication information in a controlled manner, ensuring that the core security infrastructure is already certified and validated before online functionality is introduced. This preliminary action ensures security is established first, then flexibility is added.
Solution Approach 2:
The updating unit acts as an intermediary that safely bridges the offline certified secure environment and the online authentication requirements. It mediates the addition of online functionality without directly compromising the core security certification, allowing flexibility to be added through a controlled intermediate process.
