Solution Overview
Problem
Existing biographic record processing systems face challenges in identifying and removing duplicate records due to fraud or clerical errors, especially when individuals pose under multiple identities or use disguises, making manual review ineffective.
Innovation Solution
A method that analyzes datasets containing biographic and biometric data by correlating biometrics across records to assess uniqueness, using a data processor to flag potential duplicates and perform pre-processing to enhance matching accuracy, including correcting inconsistencies in biographic data and enhancing biometric features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual review of large datasets is performed, then human operators can identify duplicate records, but the process is time-consuming and ineffective for large-scale datasets with disguised identities
Solution Approach 1:
The patent replaces manual mechanical review processes with automated biometric comparison systems. The system uses computational algorithms to compare biometric data (photographs, fingerprints, facial features) across records, substituting human operators with machine-based automated detection that can process large datasets efficiently while maintaining or improving detection accuracy.
Solution Approach 2:
The patent introduces biometric data as an intermediary element to facilitate duplicate record identification. By incorporating biometric comparisons (photograph matching, facial feature analysis) as a mediator between biographic records, the system enables automated detection of duplicates even when identities are disguised or fabricated, overcoming the limitations of manual review.
2Reliability
If photographs are included in the dataset to help identify duplicates, then visual comparison can reveal similar individuals, but human operators are unlikely to notice similar photos among large datasets
Solution Approach 1:
The patent replaces manual visual photo comparison with automated biometric image analysis systems. The system uses computational algorithms to automatically compare photographs, facial features, and biometric data across records, substituting human visual inspection with machine-based automated analysis that maintains high reliability while dramatically improving processing efficiency.
Solution Approach 2:
The patent transforms the comparison parameter from subjective human visual assessment to objective biometric measurement parameters. By converting photo comparison into quantifiable biometric data analysis (facial feature measurements, image similarity scores), the system enables automated processing that maintains reliability while enhancing productivity through standardized parameter-based comparison.
3Measurement precision
If biometric data is correlated across multiple records, then duplicate records can be identified with high accuracy, but the computational complexity and processing requirements increase
Solution Approach 1:
The patent segments the biometric comparison process into distinct modular components: biographic record retrieval, biometric data extraction, photograph comparison, facial feature analysis, and duplicate determination. This segmentation allows the complex system to be broken down into manageable modules that can be processed independently, reducing overall system complexity while maintaining high detection precision.
Solution Approach 2:
The patent uses biometric data and photograph analysis as intermediary elements that simplify the complexity of direct biographic record comparison. By introducing biometric comparison as a mediator, the system transforms complex multi-parameter record matching into focused biometric feature comparison, reducing computational complexity while enhancing detection precision.
Data Source
AI summary
A method for analyzing a dataset comprising biographic data and biometric data is disclosed. In one step, a biographic record is read that is normally meant for unique description of an individual. A biometric associated with the biographic record is also read. The biometric is correlated with a plurality of biometrics associated with other biographic records. The uniqueness of the biometric is assessed with respect to the plurality of biometrics, for example, to find duplicate biographic records with biometric matching.
