Device Security Firewall for Gaming Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic gaming machines (EGMs) face security risks due to the ability to connect with various external devices, making it difficult to ensure only tested and regulatory-approved devices communicate with them, thereby compromising gaming integrity.
Innovation Solution
Implementing a device security firewall with defined rules and an inclusion list of approved devices to control data traffic, ensuring only tested and regulatory-approved devices can operate on EGMs, thereby minimizing unauthorized control or modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If EGMs connect with various external devices to provide flexibility and capabilities, then adaptability is improved, but security reliability deteriorates due to risks from malicious and untested devices
Solution Approach 1:
The patent implements a pre-established inclusion list that identifies and approves specific external devices before they are allowed to communicate with the EGM. This preliminary authorization process ensures that only tested and regulatory-approved devices can establish connections, preventing security issues before they occur while maintaining adaptability to approved devices
2Ease of operation
If EGMs allow multiple external devices to operate without restrictions, then ease of operation is improved, but security risks increase from unauthorized control and modification
Solution Approach 1:
The patent introduces an intermediary security layer consisting of the inclusion list and firewall mechanism that mediates between external devices and the EGM. This intermediary structure maintains ease of operation for approved devices by providing seamless access while simultaneously blocking unauthorized devices, thus preventing harmful factors without complicating legitimate operations
3Reliability
If EGMs implement strict device approval processes, then security reliability is improved, but device complexity increases due to management of inclusion and exclusion lists
Solution Approach 1:
The patent applies preliminary action by pre-configuring the inclusion list with approved device identifiers and exclusion lists with blocked devices before the EGM operates. This advance preparation establishes security rules in advance, reducing the complexity of real-time decision-making and simplifying ongoing firewall management while maintaining high security reliability
