Biometric Proximity Authentication for Secure Peer-to-Peer Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Peer-to-peer transactions often face challenges in verifying the identity of participants, leading to potential fraudulent activities due to limited contact between buyers and sellers, and the complexity of using different payment applications with various user accounts.
Innovation Solution
A system and method utilizing biometric measurements and a payment processing system to authenticate transactions by comparing user-provided biometric data with stored parameters, ensuring that both parties are correctly identified and within a predetermined proximity, thereby facilitating secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication and proximity verification are implemented, then transaction security and reliability are improved, but device complexity and system complexity increase
Solution Approach 1:
The patent introduces a payment processing system as an intermediary that coordinates between multiple devices, biometric authentication services, and proximity verification mechanisms. This mediator handles the complexity of integrating biometric sensors, GPS/location services, and transaction processing, shielding end users from the underlying system complexity while maintaining high security standards.
Solution Approach 2:
The patent combines multiple authentication factors (biometric data, device proximity, user identity verification) into a unified authentication framework. By merging these separate verification mechanisms into a single coordinated process, the system achieves enhanced security without requiring users to manually manage multiple separate authentication systems.
2Reliability
If multiple authentication factors (biometric, proximity, identity) are required, then transaction reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent performs biometric template creation and storage during initial device setup, before actual transactions occur. User biometric data is captured and encrypted during onboarding, and proximity thresholds are pre-configured. This preliminary preparation eliminates the need for complex real-time biometric template generation during transactions, maintaining both security and operational speed.
Solution Approach 2:
The system automatically performs biometric matching, proximity calculation, and authentication decision-making without requiring user intervention beyond providing the biometric sample. The payment processing system autonomously verifies credentials, compares biometric data, determines device proximity, and either approves or denies the transaction, making the process as easy as presenting a biometric trait.

AI summary
Systems and methods for authenticating payment transactions using a payment card processing system are disclosed. A method for processing one or more payment transactions using a payment processing system in communication with a computer readable storage medium includes receiving a push or pull request from a first device associated with a first user, wherein the push or pull request relates to a transaction with a second device associated with a second user, receiving a first biometric measurement from the first device, and receiving a second biometric measurement from the second device. The method further includes, responsive to determining that the first biometric measurement identifies the first user, determining that the second biometric measurement identifies the second user, and determining that the first device and second device are within a predetermined relative proximity, effecting the transaction based on the push or pull request. A payment network can be configured to store or access a database including a plurality of biometric parameters that identify a plurality cardaccount holders and other transaction requirement parameters.
