Solution Overview

Problem

Conventional authentication methods for electronic transactions are inadequate and outdated, vulnerable to fraudulent activities, as they do not provide sufficient security against unauthorized access or physical possession of payment cards.

Innovation Solution

The implementation of an RFID-enabled authentication system that uses a payment card's RFID tag to determine proximity to an associated electronic device, executing a first authentication protocol if the card is present and a more restrictive second protocol if it is not, thereby enhancing security and reducing fraudulent risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional authentication methods are used, then the system is simple and easy to operate, but the security against fraudulent activities is insufficient

Engineering Contradiction:

Improvesecurity against fraudulent activitiesVSAvoidauthentication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements nested authentication protocols where a first authentication protocol is embedded within a second authentication protocol. The system determines whether to execute the first protocol or the second protocol based on whether the payment card is detected in proximity to the electronic device, creating a layered security structure that adapts to the detected conditions

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The authentication system dynamically adjusts its behavior based on real-time detection of the payment card's proximity to the electronic device. When the card is detected, a less restrictive first authentication protocol is executed; when not detected, a more restrictive second authentication protocol is executed, making the security level adaptive rather than static

Inventive Principle:

Principle #15Dynamics

2Reliability

If conventional authentication methods are used, then the transaction process is fast and efficient, but the system is vulnerable to unauthorized access

Engineering Contradiction:

Improveprotection against unauthorized accessVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial authentication action by determining whether to execute the first authentication protocol or the second authentication protocol based on card proximity detection. This selective application of authentication measures ensures adequate security without always requiring the full restrictive protocol, thus balancing security with efficiency

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system performs preliminary detection of the payment card's proximity to the electronic device before initiating the authentication process. This preliminary action allows the system to pre-determine which authentication protocol to execute, optimizing the authentication time by avoiding unnecessary restrictive steps when the card is properly present

Inventive Principle:

Principle #10Preliminary action

3Reliability

If RFID proximity detection is implemented, then the security against physical possession fraud is improved, but the device complexity increases

Engineering Contradiction:

Improvesecurity against physical possession fraudVSAvoidRFID detection system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical authentication methods (such as physical card insertion and manual verification) with RFID-based proximity detection. The electronic device automatically detects the presence and proximity of the payment card through RFID communication, substituting mechanical interactions with wireless electromagnetic detection to enhance security

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Authentication method and systems using RFID-enabled payment cards are disclosed herein where a server receives a request corresponding to authorization of a payment associated with a payment card from an electronic terminal. The server identifies an electronic device of a user associated with the payment card. The server then transmits an instruction to the electronic device to cause an RFID reader of the electronic device to determine whether an RFID tag corresponding to the payment card is located within a predetermined proximity to the electronic device. When the payment card is located within the predetermined proximity, the server executes a first authentication protocol. Moreover, when the payment card is not located within the predetermined proximity, the server executes a second authentication protocol, wherein the second authentication protocol is more restrictive than the first authentication protocol.
