Blockchain Excluded Player Detection Across Casinos
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for detecting excluded players in casinos are ineffective in sharing and updating lists across multiple jurisdictions, allowing excluded players to potentially cheat in other casinos.
Innovation Solution
A decentralized casino management system utilizing a consortium blockchain to share and synchronize excluded player data among multiple gaming operator nodes, using a consensus mechanism like Practical Byzantine Fault Tolerance to ensure data integrity and detection across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a local system is used to record and detect excluded players, then the system can detect excluded players within a single casino, but it cannot detect excluded players playing in casinos in other jurisdictions
Solution Approach 1:
The patent combines multiple local excluded player lists from different casinos and jurisdictions into a single centralized excluded player list stored on a blockchain. This allows any casino in the network to access and verify against all excluded players across all jurisdictions, not just their own local list, thereby resolving the contradiction between local detection reliability and cross-jurisdictional versatility.
Solution Approach 2:
The blockchain-based excluded player list serves multiple jurisdictions and casinos simultaneously, making the system universal. A single excluded player list can be accessed by any participating casino to detect excluded players regardless of which jurisdiction or casino the player was originally excluded from, achieving both reliability and cross-jurisdictional capability.
2Ease of operation
If a centralized database is used to store excluded player information, then data can be easily updated and accessed, but the system becomes vulnerable to tampering and data integrity issues
Solution Approach 1:
The blockchain acts as an intermediary between casinos and the excluded player list. Instead of casinos directly accessing and potentially tampering with a centralized database, they interact through the blockchain's consensus mechanism and distributed ledger, which mediates all data updates and verifications to ensure integrity while maintaining ease of access.
Solution Approach 2:
The excluded player list is replicated across multiple nodes in the blockchain network. Each node maintains a copy of the entire list, eliminating the single point of failure and tampering risk associated with centralized databases. Updates are propagated to all copies simultaneously through the consensus mechanism, maintaining both ease of operation and data integrity.
3Speed
If multiple casinos maintain separate excluded player lists, then each casino can quickly access its own list, but excluded players can bypass exclusion by playing at different casinos
Solution Approach 1:
The blockchain network pre-synchronizes the excluded player list to all participating casinos before any detection is needed. Each casino receives and stores the complete excluded player list in advance, enabling immediate local detection without needing to query other casinos in real-time, thus maintaining fast detection speed while ensuring comprehensive exclusion enforcement across all jurisdictions.
Data Source
AI summary
A gaming system, computer-implemented method and gaming device are operable to determine player identification data corresponding to a player in a property corresponding to a selected one of multiple gaming operator nodes, compare the player identification data with each of multiple data blocks in a block chain to determine a match between the player identification data and one of the data blocks, and responsive determining that the player identification data matches one of the data blocks, send an alarm signal to a gaming operator that corresponds to the selected one of the gaming operator nodes.
