Current payment systems for commercial transactions lack a secure and convenient method for users to perform transactions without relying on personal mobile devices, especially in scenarios where biometric verification and multiple identification methods are needed for security and integrity.

Innovation Solution

A phoneless universal transaction system that uses a transaction device with biometric and secondary identity data encryption, featuring a unique identification number, data sequence number, and mathematical operation encryption, which allows users to perform transactions through various architectures, including direct device access or a transaction device interface server, utilizing components like fingerprint scanners, cameras, and microphones for verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric verification and multiple identification methods are implemented, then security and integrity of transactions are improved, but device complexity and operational difficulty increase

Engineering Contradiction:

Improvetransaction securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the identification system into multiple independent components: biometric sensors (fingerprint, facial recognition), secondary identification methods (PIN, password), and encryption modules. Each component operates independently but contributes to the overall security verification process, allowing the system to maintain high security while managing complexity through modular architecture

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a transaction device as an intermediary between the user and the transaction system. This device mediates the verification process by collecting biometric data, performing encryption operations, and communicating with the transaction processor, thereby simplifying the user interface while maintaining robust security protocols in the background

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If biometric verification and multiple identification methods are implemented, then security and integrity of transactions are improved, but ease of operation deteriorates

Engineering Contradiction:

Improvetransaction securityVSAvoidtransaction convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements preliminary action by pre-registering and storing users' biometric data and secondary identification methods in an encrypted database before actual transactions occur. During transactions, the system only needs to verify against these pre-stored credentials, making the actual transaction process quick and convenient while maintaining high security standards

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-service through automated biometric verification and encryption processes. Users simply provide their biometric data, and the system automatically performs the complex verification and encryption operations without requiring user intervention in the technical processes, thereby maintaining ease of operation despite the underlying complexity

Inventive Principle:

Principle #25Self-service

3Ease of operation

If phoneless universal transaction system is implemented, then convenience for users without mobile devices is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements universality by designing a transaction device that can serve multiple functions: it acts as a verification terminal for users without mobile devices, functions as an encryption processor, and serves as a communication interface with the transaction system. This multi-functional design consolidates what would otherwise require multiple separate systems into a single device, managing complexity while expanding convenience

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A transaction system stores a biometric identification parameter used by the transaction system to perform transactions. The biometric identification parameter is received from a user and stored in a primary biometric identification parameter data file. The user is assigned a user identification number. A plurality of pieces of the primary biometric identification parameter data file are created. Each piece is assigned a data sequence number different from data sequence numbers assigned to all other pieces and a mathematical operation encryption number. Each mathematical operation encryption number represents a mathematical encryption operation that is different from mathematical encryption operations represented by all other mathematical operation encryption numbers. Each piece is encrypted using a mathematical encryption operation represented by the mathematical operation encryption number assigned to the piece in order to produce a plurality of transformed data pieces. Each transformed data piece in the plurality of transformed data pieces is assigned a transformed data identification number.
