Solution Overview

Problem

Detecting fraudulent or criminal activity in financial transactions is challenging due to the large amount of information involved and the ease of transaction, making it difficult to identify improper activity effectively.

Innovation Solution

A computer-implemented method uses a context node to identify sister nodes in a network graph by generating a network graph from input data, selecting a context node, determining patterns, and outputting sister nodes with similar characteristics, allowing for the detection of fraudulent activity patterns across different scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional monitoring methods are used to detect fraudulent activity, then the system is simple to operate, but it cannot effectively identify improper activity due to the large amount of information involved

Engineering Contradiction:
Improvedetection accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the complex fraud detection problem into multiple components: network graph construction from transaction data, pattern definition and detection modules, and sister node identification. This segmentation allows the system to handle large amounts of information systematically while maintaining detection accuracy through structured analysis of transaction relationships.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary processing layer that transforms raw transaction data into network graphs, which then serve as intermediaries for pattern detection. This intermediary representation simplifies the complex relationships in transaction data, enabling effective fraud detection without requiring direct analysis of all raw data.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If comprehensive transaction data is analyzed to detect fraud, then detection accuracy improves, but the processing time and computational resources increase

Engineering Contradiction:
Improvefraud detection accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by pre-defining fraud patterns and pre-constructing network graphs from transaction data. These preliminary structures enable rapid pattern matching and sister node identification during actual fraud detection, reducing processing time while maintaining comprehensive analysis capabilities.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates simplified copies of transaction relationships through network graphs, where complex transaction data is represented as nodes and edges. This copying approach allows efficient pattern matching and fraud detection by working with the graph representation rather than the full complexity of original transaction data.

Inventive Principle:
Principle #26Copying

3Productivity

If manual analysis of transaction patterns is performed, then false positives are reduced, but productivity and coverage of fraud detection decrease

Engineering Contradiction:
Improvefraud detection throughputVSAvoiddetection reliability
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent implements feedback mechanisms where detected patterns and sister nodes provide information back to refine the detection process. The system learns from identified fraud patterns and uses this feedback to improve future detections, maintaining high reliability while achieving automated high-throughput processing.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-service by automatically identifying fraud patterns and sister nodes without requiring manual analysis for each case. The automated pattern detection and sister node identification capabilities enable high productivity while maintaining detection reliability through consistent application of defined patterns.

Inventive Principle:
Principle #25Self-service
