Solution Overview

Problem

Current financial transaction systems face security challenges due to the vulnerabilities of PINs and passwords, which can lead to unauthorized access and fraudulent activities, particularly in point-of-sale (POS) transactions.

Innovation Solution

The PaySecure system employs biometric identification using fingerprint technology in conjunction with a pass code, integrated with advanced security algorithms and communication networks, to provide secure and convenient financial transactions by verifying customer identity through a combination of biometric data and pass codes, ensuring secure access to financial networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric identification is implemented, then security is improved, but device complexity increases

Engineering Contradiction:

ImprovesecurityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a multi-layered security architecture where biometric verification, passcode authentication, and cryptographic protocols are nested within each other. The biometric sensor captures fingerprint data, which is then processed through encryption layers and verified against stored templates in a hierarchical manner, resolving the contradiction by organizing complexity in a structured, manageable nested framework

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent introduces cryptographic intermediaries and secure communication protocols as mediators between the biometric sensing component and the financial transaction processing system. These intermediaries handle the complex data transformation and verification processes, isolating the complexity from the core transaction functionality while maintaining high security standards

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If biometric verification process is used, then unauthorized access is prevented, but transaction time increases

Engineering Contradiction:

Improveunauthorized access preventionVSAvoidtransaction time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs biometric template registration and encryption setup in advance during account initialization. Fingerprint templates are captured, processed, and stored in encrypted form before actual transactions occur. This preliminary preparation eliminates the need for complex real-time processing during transactions, thus preventing unauthorized access while minimizing transaction time

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent divides the authentication process into distinct segments: biometric data capture, template matching, cryptographic verification, and transaction authorization. Each segment is optimized independently with dedicated processing routines, allowing parallel execution and reducing overall transaction time while maintaining comprehensive security checks

Inventive Principle:

Principle #1Segmentation
