Gaming Machine Storage Authentication Key Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional gaming machines are unable to effectively prevent the reading and running of game programs from illegitimate storage media, as authentication alone is insufficient to distinguish between legitimate and pirated media.
Innovation Solution
A gaming machine with a storage medium containing a game program and an authentication program, where a reference key is stored in the storage area control component and used to authenticate the game program, ensuring that only authorized media can run the game program by matching the authentication key, thus preventing illegitimate copies from functioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication program is executed to verify game program integrity, then game program authenticity is improved, but authentication key can be copied along with game program data to illegitimate storage media
Solution Approach 1:
The authentication system is segmented into two separate components: the authentication key is stored in the storage area control component while the game program and its authentication program are stored in the storage area. This segmentation ensures that when game program data is copied to illegitimate storage media, the authentication key remains separated and cannot be replicated, thereby preventing unauthorized execution while maintaining authentication reliability.
2Ease of operation
If authentication key is stored in storage area, then authentication process is simplified, but authentication key can be easily copied to pirated storage media
Solution Approach 1:
The authentication key is extracted from the storage area and placed in the storage area control component. This extraction removes the vulnerable element (authentication key) from the copyable storage area, eliminating the root cause of piracy while keeping the authentication process functional through the control component's integrated key management.
3Reliability
If reference key is stored in storage area control component, then illegitimate storage media can be detected, but device complexity increases
Solution Approach 1:
The reference key functionality is merged with the storage area control component, combining authentication verification capabilities with existing storage control functions. This integration minimizes additional complexity while enabling reliable detection of illegitimate storage media through the unified control component.

AI summary
To enable prevention of reading and running of a game program in an illegitimate storage medium, the disclosed slot machine includes: an SSD device including a flash memory configured to store a game program for running a game and an authentication program including an authentication key, which authenticates the game program; and a memory controller SD23 having a reference key corresponding to the authentication key, which is configured to control the storage area, and a CPU core, wherein the CPU core executes the steps of: (A) executing the authentication program in which the reference key is retrieved from the memory controller to determine whether the authentication key matches with the reference key, and if the authentication key matches with the reference key, the game program is authenticated by the authentication program; (B) starting a game by running the game program when the game program is authenticated in the step (A).
