Dynamic Authentication Process Selection for Payment Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication processes for payment transactions can be inefficient, as they often require a single authentication method for various transaction types, which may delay transaction completion and are not optimized for different circumstances.
Innovation Solution
A system and method where a server computer determines the appropriate personal identification authentication process based on transaction-specific conditions, selecting from a hierarchy of processes to minimize authentication time, allowing for efficient and secure authentication independent of the service provider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single authentication process is used for all transaction types, then the system complexity is reduced, but the authentication time increases and efficiency decreases
Solution Approach 1:
The authentication system dynamically selects from multiple authentication processes based on transaction-specific conditions. The server computer determines which authentication process to perform by evaluating transaction characteristics, allowing the system to adapt its behavior rather than following a fixed single process for all transactions.
Solution Approach 2:
The system changes the authentication process parameter based on transaction type and conditions. Different authentication processes are selected and executed depending on the transaction characteristics, effectively changing the system's operational parameters to optimize for each specific transaction scenario.
2Loss of time
If multiple authentication processes are implemented for different transaction types, then authentication efficiency improves, but the system complexity increases
Solution Approach 1:
The server computer is pre-configured with multiple authentication processes and their selection criteria. Before a transaction occurs, the system has the authentication processes ready and predetermined which one should be executed based on transaction conditions, eliminating the need for real-time complex decision-making during authentication.
Solution Approach 2:
The server computer acts as an intermediary that manages the selection and execution of authentication processes. It receives authentication requests, determines the appropriate process based on transaction conditions, and coordinates the execution, simplifying the overall system architecture by centralizing the decision-making logic.
3Reliability
If authentication is performed independently of the service provider, then security improves, but the authentication process complexity increases
Solution Approach 1:
The authentication function is segmented and separated from the service provider's control. The server computer independently determines and executes authentication processes without requiring service provider involvement, dividing the authentication logic into distinct, manageable components that enhance both security and independence.

AI summary
Efficient methods and systems for verifying personal identifiers in transactions such as financial transactions are disclosed. In an exemplary method, an authentication server computer may provide an account number and a personal identifier such as a PIN to a payment processing network server computer. The payment processing network server computer may then determine which of a plurality of authentication processes to initiate.
