Browser Extension Biometric Authentication for Financial Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online account security methods, such as passwords and two-step verification, are cumbersome and vulnerable to manipulation, failing to provide adequate protection against unauthorized financial transactions and access to sensitive information.
Innovation Solution
A browser extension that utilizes biometric authentication, including facial recognition, fingerprint recognition, and voice recognition, to verify users and prevent unauthorized financial transactions by modifying web page elements and using vendor-specific virtual numbers to secure accounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passwords and two-step verification are used to secure online accounts, then account security is improved, but user convenience deteriorates and the system becomes vulnerable to manipulation
Solution Approach 1:
The patent replaces mechanical authentication systems (passwords, two-step verification) with biometric authentication using facial recognition, fingerprint scanning, or voice recognition. This substitution eliminates the need for users to remember complex passwords and perform additional verification steps, while providing more reliable security based on unique biological characteristics that cannot be easily manipulated or stolen.
2Measurement precision
If biometric authentication is implemented, then user identity verification accuracy is improved, but system complexity increases
Solution Approach 1:
The patent introduces a browser extension as an intermediary component that handles biometric authentication without requiring changes to the core browser architecture or web application infrastructure. The extension captures biometric data, performs verification, and modifies DOM elements to control content visibility based on authentication results, thereby isolating the complexity to a single modular component.
Solution Approach 2:
The authentication system is segmented into distinct functional modules: biometric data capture, identity verification, and content control. Each module operates independently, allowing the system to achieve high verification accuracy while maintaining manageable complexity through clear separation of concerns.
3Reliability
If browser extensions are used to control content visibility, then unauthorized access prevention is improved, but browser performance may deteriorate
Solution Approach 1:
The browser extension implements selective content control rather than blocking all content. It only modifies DOM elements related to financial transactions or restricted content based on authentication results, leaving the rest of the browser functionality unchanged. This partial action approach prevents unauthorized access while minimizing performance impact.

AI summary
Methods and systems described herein may monitor, by a browser, activity of a user within a web page displayed by the browser. Based on detecting, by the browser, an attempt by the first user to perform a financial transaction with an online vendor and associated with a financial account, biometric information associated with the user may be captured by the browser. Based on the captured biometric information, the browser may determine whether the first user is authorized to perform financial transactions with the online vendor and associated with the financial account. Based on a determination that the user is not authorized to perform the financial transaction, the browser may modify at least one element of the webpage to block the user from performing the financial transaction with the online vendor.
