Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identity matching systems for watchlists are prone to errors due to manual reviews of large volumes of data with inconsistencies and lack of integration with external data sources, leading to false positives and negatives, and require significant human intervention.
Innovation Solution
A machine learning system that integrates external data sources like social media and news articles, using natural language processing and AI to construct holistic identity profiles, applying unsupervised semantic modeling and graph-based clustering to accurately match identities against watchlists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual review of watchlist data is performed, then human expertise can assess complex cases, but the process becomes time-consuming and error-prone due to overwhelming data volume
Solution Approach 1:
The system segments the watchlist identification process into distinct phases: automated preprocessing of watchlist data and transaction applicant information, machine learning-based matching and scoring, and human review only for cases that require expert judgment. This segmentation allows the system to handle the overwhelming data volume automatically while reserving human expertise for complex or borderline cases, thereby reducing overall review time while maintaining accuracy.
Solution Approach 2:
The patent introduces an intermediary machine learning system that acts as a bridge between raw data and human decision-makers. This intermediary automatically processes and scores potential matches, filtering out clear non-matches and presenting only relevant cases for human review. This intermediary layer eliminates the need for humans to manually review all data, significantly reducing time loss while maintaining or improving identification accuracy through consistent automated preprocessing.
2Adaptability or versatility
If traditional watchlist databases are used, then the system can operate with established data sources, but the matching accuracy is reduced due to data inconsistencies and lack of external data integration
Solution Approach 1:
The system merges multiple data sources including traditional watchlist databases, social media platforms, news articles, and other external sources into a unified analysis framework. By combining these diverse data sources, the system creates a more comprehensive profile of both watchlist entities and transaction applicants, enabling more accurate matching decisions. The machine learning model integrates information from all sources, weighing them appropriately to improve match accuracy while maintaining adaptability across different data formats and sources.
Solution Approach 2:
The patent applies parameter changes by transforming unstructured external data into structured features that the machine learning model can process. Social media posts, news articles, and other external sources are converted into quantifiable parameters such as sentiment scores, frequency of mentions, and contextual relevance metrics. This transformation enables the system to incorporate diverse external data sources while maintaining measurement precision through consistent feature engineering and normalization.
3Measurement precision
If external data sources like social media and news articles are integrated, then more comprehensive identity profiles can be created, but the system complexity increases due to unstructured and inconsistent data formats
Solution Approach 1:
The patent replaces manual mechanical processes of data normalization and relevance assessment with automated machine learning systems. Instead of human analysts manually processing unstructured external data, the system uses natural language processing, entity recognition, and automated feature extraction to convert social media posts, news articles, and other external sources into structured features. This substitution dramatically reduces system complexity while maintaining or improving identity matching accuracy through consistent automated processing.
Solution Approach 2:
The machine learning system performs self-service by automatically adapting to different external data sources and their varying formats. The system includes automated mechanisms for learning the characteristics of different data sources, normalizing their structures, and extracting relevant features without requiring manual configuration for each new source. This self-service capability allows the system to integrate new external data sources while managing complexity through automated adaptation rather than manual setup.
4Productivity
If automated machine learning systems are used, then processing speed and consistency improve, but the ability to handle complex contextual nuances may be reduced
Solution Approach 1:
The patent implements a dynamic hybrid system that automatically adjusts the balance between automated machine learning processing and human contextual assessment. The system processes the majority of cases through automated machine learning at high speed, but dynamically routes cases with high contextual complexity, low confidence scores, or potential false positives to human reviewers. This dynamic approach maintains high processing speed for routine cases while ensuring contextual understanding accuracy for complex cases, resolving the contradiction between speed and nuanced understanding.

AI summary
Provided are a method and system for identity correlation between a transaction applicant (TA) and a watchlist entity (WE). Preexisting watchlist data and other aggregated identity data (AID) are processed to provide for comparison to a collective identity of at least the TA. Using various categorizations for the AID and the collective identity, watchlist tags are generated that can then be matched to the collective identity. As a result of the matching, a watchlist candidacy demonstrating a probability that the identity of the TA does or does not correspond to that of the WE can be generated. Various implementations of identity correlation results may be leveraged for different use cases including an automobile purchasing service, a corporate financing service, an aircraft monitoring service as well as others. Identities may comprise entities, physical objects, real estate or other items or concepts.
