Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing casino fraud detection systems struggle with accurately determining chip amounts due to blind spots and overlapping chips, and cannot detect sophisticated fraud methods like card squeegee or dealer-player conspiracies.

Innovation Solution

A fraud detection system using a game recording apparatus, image analyzing apparatus, and control device with artificial intelligence and deep learning capabilities to analyze chip positions, types, and amounts, and determine win/lose results, enabling detection of fraud and errors in chip collection and redemption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If surveillance cameras are used to monitor chip transactions, then fraud detection capability is improved, but measurement precision deteriorates due to blind spots and overlapping chips

Engineering Contradiction:

Improvefraud detection capabilityVSAvoidchip amount determination accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The system segments the monitoring task into multiple components: multiple cameras capture different views, image analysis software processes each view separately, and a control device integrates the segmented information to determine total chip amounts, overcoming the limitations of single-camera monitoring

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Image analysis software acts as an intermediary between the camera images and the fraud detection system, processing and interpreting the visual data to extract chip information that would be impossible to obtain through simple visual monitoring alone

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

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

Engineering Contradiction:

Improvechip amount recognitionVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

Instead of using physical RFID tags on each chip, the system creates visual copies/images of chips through cameras and processes these copies through image analysis, achieving chip recognition without adding physical complexity to the chips themselves

Inventive Principle:

Principle #26Copying

3Measurement precision

If image analysis is performed on recorded game progress, then fraud detection accuracy is improved, but loss of time increases due to processing requirements

Engineering Contradiction:

Improvefraud detection accuracyVSAvoidimage processing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary image capture and analysis during the game progression, rather than analyzing everything after the game ends, allowing for real-time or near-real-time fraud detection without significant time loss

Inventive Principle:

Principle #10Preliminary action

AI summary

A fraud detection system which detects fraud in a game of performing collection and redemption of chips in accordance with a win or lose result includes a camera which captures an image of chips contained in a chip tray of a dealer, an image analyzing apparatus which analyses the image captured by the camera to detect an amount of the chips contained in the chip tray, a card distribution device which determines a win or lose result of a game, and a control device which compares the win or lose result of the game and the amount of the chips contained in the chip tray before and after collection and redemption of the chips to detect fraud.
