Compromised Account Transaction Authorization with Temporary Identifiers

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional payment networks fail to immediately provide a new account number to users whose accounts are compromised, leading to inconvenience and potential loss of customers due to the inability to use compromised accounts during the transition period before receiving the new number.

Innovation Solution

A computer-implemented system that generates and uses temporary identifiers to authorize transactions for compromised accounts, allowing limited use of the accounts until a new number is received, and provides a digital form of the new account number for immediate use in certain transactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the account number is frozen upon detection of data breach, then account security is improved, but the user cannot conduct financial transactions during the transition period

Engineering Contradiction:

Improveaccount securityVSAvoidtransaction capability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a temporary identifier as an intermediary that bridges the gap between the frozen compromised account and the new account. This temporary identifier enables transactions during the transition period while maintaining security, as it is separately authenticated and does not rely on the compromised account credentials.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by issuing a temporary identifier before the new account is fully activated and before the physical card is delivered. This allows the user to conduct transactions in advance, avoiding the interruption caused by waiting for the new account to be ready.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If physical mail is used to deliver the new account number, then security is maintained, but the user experiences delay in receiving and using the new account

Engineering Contradiction:

ImprovesecurityVSAvoiddelivery time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The temporary identifier is issued in advance via electronic communication before the physical card with the new account number is mailed. This preliminary action allows the user to immediately conduct transactions without waiting for the physical delivery, while the physical mail process continues in the background for secure account number delivery.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The account transition process is segmented into two independent parts: (1) electronic issuance of temporary identifier for immediate transaction use, and (2) physical mailing of new account number for permanent account update. This segmentation allows the time-consuming physical mail process to occur without delaying the user's ability to transact.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the compromised account number is immediately frozen, then unauthorized transactions are prevented, but the user may lose customers to competing providers

Engineering Contradiction:

Improvefraud preventionVSAvoidcustomer retention

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The temporary identifier serves as a mediator that maintains the security of the frozen compromised account while simultaneously enabling transaction capability. This allows the financial service provider to prevent fraud through account freezing while avoiding customer loss by providing an alternative identifier for legitimate transactions.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system converts the harmful situation of account freezing (which blocks all transactions) into a beneficial outcome by introducing a temporary identifier that enables transactions. The compromise account remains frozen for security, but the temporary identifier transforms this restriction into an opportunity to maintain customer service continuity.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

Computer-implemented systems and methods for processing a financial transaction include receiving, from a device, a financial transaction comprising an account number associated with a financial account; based on a determination that the account number is suspended, determining whether authorization data associated with the financial account exists to authorize financial transactions associated with the account number after the account number is suspended; based on a determination that the authorization data exists, determining a first temporary identifier; receiving a second temporary identifier from the device; and based on a determination that the first temporary identifier is the same as the second temporary identifier, approving the financial transaction.
