Dual Authentication Money Processing System for Forgotten Funds

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing money processing systems that authenticate only once when opening shutters of banknote or coin deposit and withdrawal ports may lead to a higher possibility of users forgetting to take their money.

Innovation Solution

Implementing a dual authentication system where a first authentication method is used when starting a withdrawal transaction, and a second authentication method, different from the first, is required when opening each withdrawal port, ensuring that users are verified multiple times throughout the withdrawal process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single authentication method is used when opening withdrawal ports, then the operation process is simple and quick, but the possibility of users forgetting to take their money increases

Engineering Contradiction:

Improvesimplicity of withdrawal processVSAvoidprevention of forgotten money

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The authentication process is segmented into two distinct parts: first authentication when starting the withdrawal transaction, and second authentication when opening each withdrawal port. This segmentation ensures that users are verified at critical moments without requiring complete re-authentication, balancing simplicity with reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first authentication is performed in advance when the withdrawal transaction is initiated. This preliminary authentication establishes user identity early in the process, allowing the second authentication at the withdrawal port to be more streamlined while still maintaining security against forgotten money.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If multiple authentication methods are implemented throughout the withdrawal process, then the possibility of forgetting to take money is reduced, but the operation process becomes more complex

Engineering Contradiction:

Improveprevention of forgotten moneyVSAvoidcomplexity of withdrawal process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Different authentication methods are applied at different stages of the withdrawal process based on local requirements. The first authentication uses one method when starting the transaction, while the second authentication uses a different method when opening withdrawal ports. This localized approach ensures appropriate verification at each critical point without uniformly complicating the entire process.

Inventive Principle:

Principle #3Local quality

3Reliability

If the second authentication is performed for every withdrawal port, then unauthorized access is prevented, but the processing time increases

Engineering Contradiction:

Improvesecurity of withdrawal portsVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The second authentication is selectively applied based on the specific withdrawal port and transaction context. Rather than requiring authentication for every single port opening without exception, the system determines when authentication is necessary, performing it partially or excessively only when needed to prevent unauthorized access, thus minimizing time loss while maintaining security.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A possibility of occurrence of forgetting to take money is reduced. A money processing system includes: a first authentication section authenticating a user with a first authentication method when starting a withdrawal transaction; and a second authentication section authenticating a user with a second authentication method, which is different from the first authentication method, when opening an opening-closing part of each of plural withdrawal ports, to which money related to the withdrawal transaction has been conveyed.
