Biometric Identity Verification for Secure Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively utilize biometrics in uncontrolled contexts to dynamically enable access or complete transactions from unrecognized devices.
Innovation Solution
A system that registers a user's personal identification information and biometric sample as a biometric identity, allowing for verification through subsequent biometric samples to complete transactions with electronic signatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If biometrics are used for identifying an individual in uncontrolled contexts, then access and transaction completion are expedited, but security and reliability are compromised
Solution Approach 1:
The system segments the biometric data into multiple independent components (image data, signature data, personal information) that are separately verified. This segmentation allows for expedited processing of each component while maintaining overall security through comprehensive verification of all segments together.
Solution Approach 2:
The system performs preliminary actions by pre-registering and storing multiple biometric components (fingerprint, facial image, signature) during an initial setup phase. This preliminary data collection enables rapid verification during transactions without compromising security, as the pre-stored data can be quickly compared against new inputs.
2Measurement precision
If multiple biometric samples are collected and stored for verification, then identity verification accuracy is improved, but data storage requirements and system complexity increase
Solution Approach 1:
The system extracts and stores only the essential verification components from biometric data (image data, signature data, personal information) rather than storing complete raw biometric datasets. This extraction approach maintains verification accuracy while significantly reducing storage requirements and processing complexity.
Solution Approach 2:
The system creates simplified digital copies of biometric characteristics (facial images, signatures, fingerprints) that capture the essential verification information without requiring storage of the original complex biometric data. These copies enable accurate verification with reduced computational and storage overhead.

AI summary
A system for verifying an identity includes a memory that stores instructions and a processor that executes the instructions. When executed, the instructions cause the system to: receive a first request to register an identity for a party; prompt the party to provide personal identification information and a first biometric sample; persistently associate the personal identification information with the first biometric sample as a biometric identity; receive a second request to complete a transaction with an electronic signature of the party based on the first biometric identity; prompt the party to provide the personal identification information and a second biometric sample; verify the personal identification information and the second biometric sample using the biometric identity; create a verification based on verifying the personal identification information and the second biometric sample; and persistently mark an electronic record of the transaction with the verification.
