Biometric Authorization System for Online Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional password security methods are limited by character restrictions, difficulty in remembering randomly generated passwords, and vulnerability to guessing or discovery, while biometric data offers a higher level of security but requires innovative authorization methods for online transactions.
Innovation Solution
A biometric authorization system that uses a biometric sensing device to verify a user's identity through unique physical or behavioral traits, allowing a second user to authorize a first user's online purchases by countersigning an online account token when the biometric data matches reference images, enabling secure transactions with customizable spending limits and time constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passwords are used for security, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The patent replaces the mechanical/password-based authentication system with a biometric authentication system. Instead of relying on users to remember and enter complex passwords, the system uses biological characteristics (fingerprint, facial recognition, iris scan) to automatically verify user identity, thereby maintaining ease of operation while significantly improving security reliability
Solution Approach 2:
The patent introduces an intermediary authorization mechanism where a second user must authorize actions for a first user. This intermediary step acts as an additional security layer between the user and the system, allowing controlled access and transaction authorization without requiring the primary user to have full system access credentials
2Reliability
If randomly generated passwords are used, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent eliminates the need for users to generate, remember, and type complex random passwords by substituting biometric authentication. The system captures and processes biological data automatically, providing both high security through unique biometric traits and ease of use through automatic recognition without manual password entry
3Reliability
If biometric data is used for authorization, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal biometric authentication system that can be integrated across multiple devices and applications. The same biometric data (fingerprint, facial features, iris pattern) serves as the authentication credential across different platforms, reducing the need for device-specific security mechanisms and simplifying the overall system architecture despite the advanced technology involved

AI summary
A second user can authorize a first user to take or complete an online action by submitting one or more biometric images. For example, the second user can authorize a purchase by the first user on an online store. The second user can submit the one or more biometric images on the electronic device being used by the first user, or the second user can submit the biometric image or images remotely using another electronic device.
