Wearable Biometric Authentication for Secure Payment Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional payment card transaction systems rely on physical card possession, which is not a reliable indicator of ownership or authorization, as cards can be lost, stolen, or counterfeited, leading to fraudulent activities.
Innovation Solution
A wearable computing device with a camera and processor is used to capture and compare biometric samples, such as iris images or motion, to authenticate the user as the authorized cardholder, ensuring secure payment transactions by verifying the user's identity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical card possession is used for authentication, then the system is simple and easy to operate, but the security and reliability of transaction authorization deteriorates
Solution Approach 1:
The patent replaces the mechanical physical card system with a biometric authentication system using iris recognition. The wearable device captures iris images and compares them against stored reference samples, substituting the mechanical card-swiping action with optical biometric verification. This resolves the contradiction by maintaining system usability while dramatically improving authentication reliability through unique biological characteristics that cannot be lost, stolen, or counterfeited like physical cards.
Solution Approach 2:
The patent creates a digital copy of the cardholder's biometric data (iris pattern) and stores it in the wearable device for comparison during transactions. This biometric template acts as a secure digital copy that replaces the physical card, enabling reliable authentication without requiring the actual physical presence of the card. The copying principle allows the system to verify identity through data comparison rather than physical possession.
2Reliability
If biometric authentication is implemented, then the security and authorization verification improve, but the device complexity and operation difficulty increase
Solution Approach 1:
The wearable device performs biometric authentication automatically without requiring active user intervention. The device continuously monitors and captures iris data, automatically comparing it against stored reference samples. This self-service capability eliminates the need for the user to manually input data or follow complex authentication procedures, maintaining ease of operation while implementing robust biometric verification. The system serves itself by autonomously verifying the cardholder's identity.
Solution Approach 2:
The patent performs preliminary biometric registration during device setup, storing the cardholder's iris pattern in advance. This preliminary action creates a reference sample that enables rapid, automatic authentication during subsequent transactions. By preparing the biometric template beforehand, the system eliminates the need for complex real-time processing during actual use, maintaining operational convenience while ensuring secure verification.

AI summary
A computer-based method for authenticating a suspect consumer as an authorized cardholder during a payment card transaction is provided. The method includes registering the authorized cardholder within a portable computer device by receiving a reference sample of the authorized cardholder. The portable computer device includes a processor, a memory, and a camera. The method also includes storing, in the memory, the reference sample of the authorized cardholder and associated payment card information. The method further includes using the camera to capture a transaction sample of the suspect consumer during the payment card transaction using the camera. The method also includes comparing, by the processor, the transaction sample to the reference sample stored in the memory. The method further includes authenticating the suspect consumer as the authorized cardholder based at least in part on the comparison.
