Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The gaming industry faces significant capital investment in gaming machines, and there is a need for techniques to improve existing machines while also enhancing security to prevent tampering and intellectual property theft.
Innovation Solution
A gaming machine with a main circuit and an auxiliary circuit, where the auxiliary circuit processes challenge data to output valid response data to the main processor, modifying gameplay if valid response data is not received, thereby enhancing security and enabling additional processing functionalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an auxiliary circuit is added to enhance security, then security and reliability are improved, but device complexity increases
Solution Approach 1:
The system is divided into a main circuit and a separate auxiliary circuit. The auxiliary circuit is a distinct module that can be added to existing gaming machines without redesigning the entire system. This segmentation allows security enhancement while maintaining the original system's structure and minimizing overall complexity increase.
Solution Approach 2:
The auxiliary circuit is designed with multi-functionality, serving both as a security authentication device and as a potential platform for additional processing functions. This universal design justifies the added complexity by providing multiple benefits from a single component addition.
2Reliability
If authentication code is implemented to modify gameplay, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The authentication process operates automatically without requiring manual intervention from players or operators. The main circuit and auxiliary circuit autonomously exchange challenge-response data, and gameplay modification occurs automatically based on authentication results. This self-service mechanism maintains ease of operation despite enhanced security checks.
3Reliability
If challenge-response authentication is implemented, then security is improved, but loss of time increases
Solution Approach 1:
The challenge-response authentication is implemented as a periodic or event-triggered process rather than continuous verification. Authentication occurs at specific intervals or when particular game events occur, reducing the time overhead compared to constant verification while maintaining security effectiveness.
