Biometric Login for Multi-User Game Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current game devices only allow one user to log in to the operating system, limiting trophy acquisition to a single user during multiplayer games, necessitating a solution for multiple users to log in easily.
Innovation Solution
An information processing apparatus with a communication section, image capture section, registered user information holding section, biometric authentication, and login controller to facilitate multiple user logins by capturing images, comparing biometric data, and associating users with their devices for secure login.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only one user is allowed to log in on the OS of the game device, then the system is simple to operate, but multiple users cannot receive trophies in multiplayer games
Solution Approach 1:
The system automatically performs user identification and login processing by capturing images with the imaging apparatus and comparing biometric information, eliminating the need for manual login operations. This allows multiple users to log in seamlessly without complicating the operation process.
Solution Approach 2:
The patent replaces traditional manual login mechanisms (keyboard input, button pressing) with an automated image capture and biometric recognition system. The imaging apparatus captures user images, and the login control unit automatically processes authentication, substituting mechanical interaction with automated optical and computational processes.
2Adaptability or versatility
If biometric authentication and image capture mechanisms are added to enable multiple user logins, then multi-user trophy acquisition is enabled, but the device complexity increases
Solution Approach 1:
The imaging apparatus serves multiple functions: it captures images for biometric authentication, stores user profile images, and displays login information. By making the imaging apparatus multi-functional, the patent reduces the need for separate dedicated components, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent combines the login authentication function with the existing imaging apparatus and display unit. Instead of adding separate authentication hardware, the system merges biometric recognition capabilities into the existing image capture and display infrastructure, reducing overall system complexity.
3Ease of manufacture
If manual login procedures are used for each user, then the login process is simple to implement, but it is time-consuming for multiple users
Solution Approach 1:
The system performs preliminary actions by capturing user images and storing biometric information in advance. When users need to log in, the authentication process quickly compares current images with stored data, eliminating the need for time-consuming manual procedures during actual login attempts.
Solution Approach 2:
The login system operates autonomously by automatically capturing images, comparing biometric data, and processing authentication without requiring manual intervention. This self-service approach dramatically reduces login time for multiple users while maintaining implementation simplicity through automated workflows.

Data Source
AI summary
A communication section receives a connection request from a game controller to connect the game controller with an information processing apparatus. A registered user information holding section holds biometric information of a user registered in the information processing apparatus. A biometric authentication portion compares biometric information of a user included in a taken image with biometric information held in the registered user information holding section to determine whether the imaged user is a user registered in the information processing apparatus. After the imaged user is found to be a user registered in the information processing apparatus, a login controller executes login processing of the user, or to be more specific, stores information for identifying a device included in the taken image and information for identifying the user into a login user storage portion by relating these items of information with each other.
