Solution Overview

Problem

Existing casino fraud detection systems face challenges in accurately determining chip amounts due to camera blind spots, chip stacking, and advanced betting methods, and fail to detect fraud involving dealers and players through simple detection of winning amounts.

Innovation Solution

A fraud detection system utilizing a game recording apparatus, image analyzing apparatus, and control device with artificial intelligence and deep learning capabilities to analyze game progress, recognize chip positions and types, and compare chip amounts before and after settlement, detecting fraud through image analysis and win/lose results.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If surveillance cameras are used to detect fraud, then fraud detection capability is improved, but measurement precision deteriorates due to camera blind spots and chip stacking

Engineering Contradiction:
Improvefraud detection capabilityVSAvoidchip amount determination accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The system segments the fraud detection process into multiple independent analysis components: image analysis for chip position and type recognition, RFID reading for chip amount verification, and control device coordination for comprehensive fraud detection. This segmentation allows each component to specialize in specific tasks, overcoming the limitations of单一 surveillance camera systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary RFID reading device between the surveillance camera and the chip amount determination process. The RFID device acts as a mediator that provides accurate chip amount data to complement the visual information from cameras, resolving the precision problem caused by blind spots and chip stacking.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If simple detection of winning amounts is used, then device complexity is reduced, but fraud detection capability deteriorates as it cannot detect advanced betting methods

Engineering Contradiction:
Improvedetection system simplicityVSAvoidfraud detection capability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The control device is designed with multi-functionality to perform diverse fraud detection tasks: analyzing image data for chip positions, reading RFID tags for chip amounts, determining win/lose results, and coordinating settlement verification. This universal device replaces multiple specialized devices while enhancing fraud detection capability against advanced betting methods.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements feedback mechanisms where the control device continuously compares the sum of player chips with dealer chip tray changes, and verifies settlement amounts against win/lose results. This feedback loop enables detection of sophisticated fraud patterns by identifying inconsistencies that simple detection systems would miss.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If RFID tags are attached to each chip, then chip amount recognition is improved, but device complexity increases

Engineering Contradiction:
Improvechip amount recognition accuracyVSAvoidsystem structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system merges the RFID reading function with the existing surveillance camera system and control device. Rather than creating a separate complex RFID infrastructure, the RFID reader is integrated into the existing fraud detection framework, combining multiple functions (visual monitoring, RFID reading, fraud analysis) into a unified system that manages complexity effectively.

Inventive Principle:
Principle #5Merging (Combining)
