Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Portable electronic devices, such as smartphones, are vulnerable to fraudulent financial transactions due to security gaps in financial applications and user behavior, leading to potential financial losses for users.

Innovation Solution

Implementing a system that detects the initiation of a financial transaction and queries an associated account identifier to determine if it is linked to fraudulent activity, transmitting a fraud warning to the user's device before the transaction is completed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If financial applications are made more accessible and easier to use, then ease of operation is improved, but vulnerability to fraudulent transactions increases

Engineering Contradiction:

Improveease of use of financial applicationsVSAvoidvulnerability to fraudulent transactions

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary fraud detection by querying the account identifier against a database of known fraudulent accounts before the financial transaction is completed. This advance checking allows the system to warn users of potential fraud before they commit the transaction, maintaining ease of use while preventing harm.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary fraud detection layer between the user and the financial transaction. By inserting a warning mechanism that checks account identifiers against known fraudulent accounts, the system mediates between easy access to financial applications and protection from fraud, allowing users to make informed decisions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If fraud detection queries are performed for every transaction, then reliability against fraud is improved, but processing time increases

Engineering Contradiction:

Improvefraud detection accuracyVSAvoidtransaction processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial action by performing fraud detection queries selectively rather than for every single transaction. The warning is generated when there is a potential match with known fraudulent accounts, allowing the system to maintain high reliability for suspicious transactions while avoiding unnecessary delays for legitimate transactions.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system skips detailed fraud verification for transactions that clearly do not match known fraudulent patterns, allowing legitimate transactions to proceed quickly. The fraud detection mechanism rushes through the verification process efficiently, only stopping to warn users when actual fraud risk is detected.

Inventive Principle:

Principle #21Skipping (Rushing through)

AI summary

An electronic device includes a communication device and one or more processors operable with the communication device. When the communication device receives a financial transaction initiation communication from at least one remote electronic device having an electronic device identifier from which a financial transaction initiation request was received by the remote electronic device, the one or more processors determine whether the electronic device identifier is associated with an account identifier of an account used for fraud. When the electronic device identifier is associated with the account identifier of an account used for fraud, the one or more processors cause the communication device to present a prompt on the remote electronic device warning of fraudulent activity.
