Solution Overview

Problem

Current methods for preventing unauthorized use of payment account data are inadequate, especially in non-face-to-face transactions, as they rely on static authentication data that can be vulnerable to various attacks, and compromised accounts require new card issuance with updated details, leading to additional expenses and inconvenience.

Innovation Solution

Incorporating a processor and display on a payment device that can dynamically change card data for each transaction, allowing the display of new payment and non-payment information, such as CVVs and logos, which can be updated externally or internally, ensuring that even if account information is compromised, the card can be rendered useless for further transactions without needing a new card.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If static authentication data is used on payment cards, then the card structure remains simple and manufacturing is easy, but security against fraud and counterfeiting deteriorates in non-face-to-face transactions

Engineering Contradiction:
ImprovesecurityVSAvoidcard structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic authentication data that changes with each transaction. The card includes a processor and display that generate and display varying authentication data (such as CVV codes) for each transaction, making the static card structure dynamic in function. This resolves the contradiction by adding security through dynamic behavior without fundamentally changing the card's physical simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the authentication parameter from static to dynamic. Instead of using a fixed CVV or authentication code printed on the card, the system generates different authentication data for each transaction based on transaction-specific parameters. This parameter change enhances security while maintaining the card's structural simplicity.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If static account data is used for authentication, then the system is simple and easy to operate, but vulnerability to hacking, skimming, and phishing increases

Engineering Contradiction:
Improveprotection against unauthorized useVSAvoidtransaction process
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically generates authentication data for each transaction, making the authentication process as secure as it is simple. The card displays different authentication codes for each transaction, and the user simply enters the current display without needing to manage complex security procedures. This maintains ease of operation while significantly improving protection against unauthorized use.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The card system performs self-service authentication by automatically generating and displaying unique authentication data for each transaction. The card itself manages the security function without requiring external intervention or complex user actions, maintaining simplicity while enhancing security against hacking and skimming.

Inventive Principle:
Principle #25Self-service

3Reliability

If compromised cards are replaced with new cards, then security is restored, but additional expenses and cardholder inconvenience increase

Engineering Contradiction:
Improveaccount securityVSAvoidcard delivery waiting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The dynamic authentication data ensures that even if a card is compromised, the authentication codes displayed on the card will be different for subsequent transactions. This eliminates the need for card replacement and restores security without causing time loss or additional inconvenience to the cardholder.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system prepares for security breaches by continuously generating new authentication data before any compromise occurs. The dynamic nature of the authentication codes means that the card remains valid and functional even after potential compromise scenarios, eliminating the need for preliminary card replacement actions.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If dynamic changing data is implemented on cards, then security against compromised data improves, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvedata compromise protectionVSAvoidcard production
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent implements dynamic authentication data generation using a processor and display on the card. The system generates different authentication codes for each transaction based on transaction-specific parameters, enhancing security while maintaining manufacturing feasibility through integrated electronic components.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The card integrates multiple functions including dynamic data generation, display, and authentication within a single device. This multi-functionality approach consolidates security features into one system rather than requiring separate components, making the increased complexity more manageable and potentially reducing overall manufacturing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
