Electronic Device User Profile Management for Shared Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices in public spaces face security issues and inefficiencies when shared among users, as unauthorized access is unavoidable and data remains on the device, leading to security concerns and limited usability.
Innovation Solution
An electronic device with a processor and communication circuit that manages user login and logout requests, transmits data to an external device, and changes settings based on user-specific information, ensuring secure data deletion and tailored user environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same password is shared among authorized users, then multiple users can access the electronic device, but unauthorized users may also gain access and security issues occur
Solution Approach 1:
The system segments user authentication by creating individual user accounts with unique credentials for each authorized user. Instead of sharing a single password, each user has their own login credentials, and the system maintains separate user profiles that are activated based on which user is currently authenticated. This segmentation ensures that only authorized users can access the device while preventing unauthorized access.
Solution Approach 2:
The system applies local quality by providing personalized settings and data specific to each user's location or context. When a user logs in, their specific user profile is activated with customized settings, applications, and data relevant to that user. This ensures that each user experiences a tailored environment while maintaining security boundaries between different users.
2Ease of operation
If the same data are provided to all users in the same setting status, then users can use the device, but users cannot efficiently use the device for personalized tasks
Solution Approach 1:
The system implements local quality by maintaining distinct user profiles with customized settings, applications, and data for each user. When a user logs in, their specific profile is activated, providing them with personalized configurations and data relevant to their needs. This allows each user to efficiently perform their specific tasks while sharing the same physical device, thereby improving both ease of operation and productivity.
3Duration of action of stationary object
If data remain in the electronic device after user sessions, then device functionality is maintained, but security issues occur due to potential unauthorized access
Solution Approach 1:
The system extracts user-specific data and settings from the device's permanent storage and loads them into volatile memory when a user logs in. When the user logs out, their data is removed from active memory and not persisted in a readily accessible state. User profiles are stored in a protected manner, requiring authentication to access. This approach maintains data persistence for authorized users while enhancing security by preventing unauthorized access to stored data.
4Adaptability or versatility
If password sharing is implemented among authorized users, then device sharing is enabled, but the system complexity increases due to password management
Solution Approach 1:
The system implements self-service by automatically managing user authentication and profile activation. When a user logs in with their credentials, the system automatically activates their specific user profile, loads their customized settings and data, and configures their personal environment without requiring manual intervention. This automated approach enables device sharing among multiple authorized users while reducing the complexity of password management compared to manual password sharing arrangements.
