EGM Blockchain Logging for Secure Non-Volatile Machine Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic gaming machines (EGMs) face challenges in securely storing essential data such as unique identifiers and configuration information, which are often difficult to read and prone to human error in dimly lit environments, and traditional logging methods are cumbersome and prone to fraud.
Innovation Solution
Implementing a wireless transmitter and memory device within the EGM cabinet to securely store data, using a blockchain system for decentralized and immutable data storage, allowing wireless transmission and retrieval of EGM data without manual reading, and utilizing a peer-to-peer network for data tracking and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data is stored on physical license plates or manual logbooks in conventional EGMs, then data can be accessed visually, but the data is difficult to read in dimly lit environments and prone to human error
Solution Approach 1:
The patent replaces the mechanical/visual system of physical license plates and manual logbooks with an electronic wireless transmission system. The EGM controller wirelessly transmits data to external devices, eliminating the need for visual reading in dimly lit environments and reducing human error associated with manual logging.
2Reliability
If manual logging methods are used in conventional EGMs, then data can be recorded, but the process is cumbersome and prone to fraud
Solution Approach 1:
The system enables self-service automated data logging where the EGM controller automatically generates and transmits logs without human intervention. This eliminates manual logging processes, reduces complexity of manual procedures, and improves reliability by preventing fraud through automated immutable recording.
Solution Approach 2:
The patent implements feedback mechanisms where the EGM controller automatically transmits data to external devices and receives acknowledgments. This automated feedback loop ensures data integrity, reduces manual intervention, and creates a reliable audit trail that prevents fraud while maintaining system simplicity.
3Stability of the object's composition
If EGM data is stored without persistent memory in conventional systems, then the system can operate with simpler memory requirements, but startup and initialization data are lost without permanent storage
Solution Approach 1:
The patent introduces an intermediary wireless transmission system that bridges the gap between volatile memory and permanent storage requirements. The EGM controller can temporarily store data in volatile memory during operation and wirelessly transmit it for persistent storage externally, or use small persistent memory for critical data, reducing the need for large onboard persistent storage while maintaining data stability.
Data Source
AI summary
An electronic gaming machine (EGM) includes a cabinet, a wireless transmitter, a memory device storing a unique device identifier (ID) of the EGM, and a game controller. The game controller is configured to execute a first node of a blockchain network on the EGM and store a first copy of the blockchain on a first memory partition, execute a second node of the blockchain network on the EGM and store a second copy of the blockchain on a second memory partition, generate a metering event associated with game play, submit a first blockchain transaction to the blockchain network, causing the first blockchain transaction to be added to a new block on the blockchain, and locally determine consensus for the new block on the blockchain between the first node and the second node of the EGM.
