Solution Overview

Problem

Current ATMs rely on physical cards and PIN codes, which can be compromised or forgotten, leading to inconvenience and security issues.

Innovation Solution

Implementing a biometric authentication system that uses a combination of numeric identification data, fingerprint scanning, iris scanning, and facial recognition to securely authenticate users, allowing access to financial accounts without the need for physical cards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical ATM cards and PIN codes are used for authentication, then users can access financial accounts, but the system becomes vulnerable to theft, loss, and identity compromise

Engineering Contradiction:

Improveauthentication securityVSAvoidtheft and identity compromise

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical authentication methods (physical cards and PIN codes) with biometric authentication systems including fingerprint scanners, iris scanners, and facial recognition cameras. This substitution eliminates the vulnerability to physical card theft and PIN compromise while maintaining authentication functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the authentication parameter from mutable data (PIN codes that can be guessed or logged) to immutable biological characteristics (fingerprints, iris patterns, facial features). This parameter change fundamentally improves security by making authentication credentials impossible to steal or compromise in traditional ways.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If multiple biometric verification methods are implemented, then authentication security is enhanced, but device complexity increases

Engineering Contradiction:

Improveauthentication securityVSAvoidmulti-modal biometric verification system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple biometric authentication functions (fingerprint scanning, iris scanning, facial recognition) into a single ATM system. This multi-functionality approach allows the system to offer enhanced security through multiple verification methods while maintaining a unified device interface for users.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent divides the biometric authentication process into separate functional modules (fingerprint scanner, iris scanner, facial recognition camera), each handling a specific biometric modality. This segmentation allows for independent optimization of each sensor while managing overall system complexity through modular architecture.

Inventive Principle:

Principle #1Segmentation

AI summary

Disclosed are methods, apparatus, and systems of biometric identification and authentication. In one embodiment, a method to authenticate a user at an automated teller machine is disclosed. In this embodiment, the method comprises: retrieving, by a processor of the automated teller machine, a numeric identification data inputted by the user; comparing, by the processor or by a processor of a remote sever, the numeric identification data against a stored set of numeric identification data in a user database stored in a memory communicatively coupled to the automated teller machine; and narrowing, by the processor or by the processor of the remote server, a user population to a first narrowed set of the user population based on the comparison of the numeric identification data against the stored set of numeric identification data. Multiple biometric identification techniques may then be used to authenticate the user at the automated teller machine.
