Fraud Detection System in Casino Identifying Players at the Table With Cameras and Image Analysis

This patent describes a system that records play at casino gaming tables, analyses the images to recognise each player’s face, and assigns every player an identity number so the casino can spot fraud. It comes from Angel Group, a Japanese maker of casino playing cards and gaming equipment.

The Problem

Casinos handle large sums of money across many tables at once, which makes them targets for cheating, collusion, and other fraud. Watching every table closely enough to catch a coordinated scam is hard for human staff alone, especially when the people involved move between tables or return on different days. Operators need a reliable way to keep track of who is playing where, to link a person’s activity across a session, and to flag suspicious patterns, all without slowing down the game or depending entirely on a guard’s memory of faces.

What This Invention Does

The system is a player detecting system for a casino that has many gaming tables. It combines three main parts: a game recording apparatus that captures what happens at the tables, an image analysing apparatus that processes those recordings, and a control device that ties everything together. The control device extracts a face image of a player from the captured footage and identifies that player by attaching an identity number, or ID, to them. Once each player carries an ID, the system can follow their activity across tables and over time, which is the foundation for detecting fraud. By turning camera footage into identified, trackable players, the casino gains an automated layer of monitoring that supports its security and surveillance staff.

Key Features

• Game recording apparatus. Captures the activity at the casino’s gaming tables.
• Image analysing apparatus. Processes the recorded footage for useful information.
• Control device. Coordinates recording and analysis and manages player identification.
• Face extraction. A player’s face image is extracted from the captured footage.
• Player ID assignment. Each identified player is given an identity number for tracking.

Who Is Behind It

The applicant is Angel Group Co., Ltd., a company based in Japan whose roots go back to 1949 and which is a major supplier of casino playing cards, gaming currency, and table operation and security systems worldwide. The named inventor is Yasushi Shigeta. This filing is a divisional application from an earlier related application, and it claims priority from Japanese applications first filed in 2015.

Why It Matters

Surveillance and security are central to how casinos protect their revenue and their licences. A system that automatically identifies and tracks players from camera footage can help operators detect fraud and collusion faster and more consistently than manual watching alone. Securing the technology in Australia is relevant given the country’s regulated casino and gaming industry. The use of facial recognition in such settings also raises privacy considerations that operators must manage under local law.

• Casino – the environment the system is built for.
• Closed-circuit television – the camera surveillance that feeds the system.
• Computer vision – the broader field behind the image analysis.
• Anti-fraud – the purpose the monitoring serves.
