Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional financial transactions rely on outdated technology, using number-based payment devices that are vulnerable to theft and manipulation, and involve complex, costly, and risky processes with multiple intermediaries.
Innovation Solution
The system employs active authentication transaction keys, generated uniquely for each transaction, which are wirelessly received by ATMs or other financial instruments, allowing for secure fund transfers and eliminating the need for static account information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If number-based payment devices and keys are used for financial transactions, then the transaction process can be established, but the security is compromised as these numbers and keys are easily stolen and manipulated
Solution Approach 1:
The patent implements dynamic authentication by generating unique transaction keys for each transaction rather than using static card numbers and keys. The system creates time-sensitive, one-time authentication credentials that change with each transaction, making stolen credentials useless for future transactions. This dynamic approach directly addresses the security vulnerability of static number-based payment devices.
Solution Approach 2:
The patent changes the fundamental parameter of authentication from static numerical values to dynamic cryptographic keys. The system generates unique authentication parameters for each transaction that are mathematically derived but not easily predictable or replicable. This parameter transformation from simple numbers to complex cryptographic values significantly increases security while maintaining transaction functionality.
2Reliability
If multiple intermediary systems are involved in processing transactions, then transaction validation can be performed, but the complexity and cost increase while processing time extends
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediary systems from the transaction flow. By implementing a streamlined authentication mechanism that works directly between the payment device and the merchant's processing system, the patent removes redundant validation layers while maintaining security. The dynamic key system provides built-in authentication that reduces reliance on multiple intermediary validation steps.
Solution Approach 2:
The patent introduces a cryptographic authentication protocol as an intelligent intermediary that enables direct communication between parties without requiring multiple traditional banking intermediaries. The dynamic key system acts as a trusted mediator that provides security verification without the need for complex multi-system validation chains, thereby reducing overall system complexity while maintaining reliability.
3Reliability
If multiple intermediary systems process transaction data, then validation can occur, but unnecessary costs and processing time are added
Solution Approach 1:
The patent implements preliminary authentication by generating and validating transaction keys before the actual transaction processing. The dynamic key system performs security verification in advance, ensuring that authentication is completed prior to fund transfer. This preliminary action prevents the need for time-consuming post-transaction validation and reduces overall processing time while maintaining security standards.
Solution Approach 2:
The patent enables the transaction process to skip unnecessary intermediary validation steps by using self-contained dynamic authentication credentials. The transaction key system allows the transaction to rush through the processing pipeline directly without being delayed by multiple intermediary system checks, thereby reducing processing time while maintaining adequate validation through the cryptographic authentication mechanism.

Function Achieved in This Case
This approach enhances security by reducing the risk of fraud, simplifies transaction processes, and eliminates unnecessary costs and complexity, while enabling the use of non-numeric identifiers in financial transactions.
Implementation Method 1
receiving an active authentication transaction key at an ATM from a mobile financial transaction instrument via a wireless communication protocol
Data Source
AI summary
A method of performing a fund transfer at an ATM includes receiving an active authentication transaction key at an ATM from a mobile financial transaction instrument via a wireless communication protocol, generating a PIN at the ATM, and storing the PIN in a machine readable storage medium. An authorization request message is transmitted to a financial institution identified by the active authentication transaction key. The authorization request message includes the PIN and at least a portion of the active authentication transaction key. The PIN is received from a user of the mobile financial transaction instrument, and the funds are dispensed in response to receiving the PIN.
