Game Authentication System Using Segmented Identifier Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game systems face security issues due to reliance on recording media for user authentication, allowing unauthorized access and requiring cumbersome password input, which can be costly to implement across all devices.
Innovation Solution
A game system that uses a management apparatus with an authentication section to verify a set of first and second identifiers, where the first identifier is unique to the user or their belongings, and the second identifier is a password or biological information, ensuring secure access without the need for password input on all devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If recording media are used for user authentication, then user identification is enabled, but security is compromised as stolen media can be used for impersonation
Solution Approach 1:
The authentication system is divided into two separate components: a recording medium (first identifier) and a personal identification input device (second identifier). Both components are required for successful authentication, so the recording medium alone cannot be used for impersonation. This segmentation resolves the security issue while maintaining convenience as users simply insert the medium and input their PIN or biometric data.
Solution Approach 2:
A management apparatus acts as an intermediary between the recording medium and the personal identification information. It stores the recording medium identifier, manages authentication results, and provides time limit information. This intermediary coordinates the verification process and ensures that both the recording medium and personal identification are validated together, preventing impersonation while maintaining user convenience.
2Reliability
If password input devices are added to all game devices for enhanced security, then authentication security is improved, but device complexity and cost increase
Solution Approach 1:
The management apparatus serves multiple functions: it stores recording medium identifiers, manages authentication results, provides time limit information, and coordinates verification across different game devices. By centralizing these authentication management functions in a single multi-functional apparatus, the system achieves enhanced security without requiring complex password input devices in each individual game device.
Solution Approach 2:
The management apparatus acts as an intermediary that handles the complex authentication management tasks centrally. It stores authentication data, manages time limits, and provides verification information to game devices. This intermediary approach allows game devices to maintain simple structures while still achieving secure authentication through the centralized management system.
3Reliability
If authentication time limits are implemented, then service security is improved, but additional management complexity is introduced
Solution Approach 1:
Time limit information is set in advance when authentication results are stored in the management apparatus. The system pre-configures validity periods for authentication, so that time-based security control is automatically enforced without requiring real-time complex calculations or continuous monitoring. This preliminary setting of time limits enhances service security while keeping the management system relatively simple.

AI summary
A game system includes a management apparatus and a game device. The management apparatus includes an authentication section for obtaining results of authentications using first and second identifiers that should correspond to a user. When the results of the authentications are affirmative, a validity time limit is associated with the first identifier. In addition, the game device includes a confirmatory identifier acquirer for acquiring a confirmatory identifier that should correspond to the user, and an inquiry maker for making an inquiry asking the management apparatus to check whether or not the first identifier conforming to the confirmatory identifier is stored in the management apparatus. The inquiry inquires the management apparatus to check whether or not the validity time limit corresponding to the first identifier is a time after the present time when the first identifier conforming to the confirmatory identifier is stored in the management apparatus. A permitter of the management apparatus permits execution of a service associated with the first identifier used in the inquiry when results of checks by the manager in response to the inquiry are affirmative.
