Secure Payment Token Update for Online Authentication Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure payment transaction devices lack flexibility and security enhancements, particularly in online digital money systems, where they are not initially designed for integration and may compromise security if additional functions or codes are added.
Innovation Solution
A secure payment transaction device is enhanced with an updating unit to add online authentication information, allowing it to be reused 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 additional functions or codes are added to secure payment transaction devices, then flexibility and adaptability improve, but security may be compromised
Solution Approach 1:
The patent segments the authentication system into two distinct parts: the secure payment transaction device maintains its original security-critical functions, while a separate online authentication information element is introduced for online system integration. This segmentation allows the device to gain online functionality without compromising its core security architecture, as the additional authentication information is isolated and managed separately from the device's primary security functions.
Solution Approach 2:
The patent introduces online authentication information as an intermediary element that mediates between the secure payment transaction device and the online digital money system. This intermediary allows the device to participate in online transactions without requiring direct integration that would compromise security, as the online authentication information acts as a buffer that enables communication while preserving the device's security boundaries.
2Reliability
If secure payment transaction devices are integrated into online digital money systems, then system resilience and security improve, but device complexity increases
Solution Approach 1:
The patent extracts the online authentication functionality from the core secure payment transaction device and represents it as separate online authentication information. This extraction allows the device to benefit from enhanced system security through online integration while avoiding the complexity of embedding full online authentication mechanisms within the device itself. The complex online authentication logic remains in the external system, not in the device.
Solution Approach 2:
The patent creates a universal solution where the secure payment transaction device can operate in multiple contexts (offline token system and online digital money system) by adding online authentication information. This multi-functionality allows the same device to serve both offline and online purposes without requiring separate devices or complex configuration, thereby improving system resilience without proportionally increasing device complexity.
