Sensor-Based Device Sharing Module for Automatic User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional device sharing systems require manual login and logout, leading to issues such as forgotten guest sessions, automatic logout frustrations, and inability to maintain personalized experiences in multi-user environments, especially in unsupervised settings where manual logins and logouts are impractical.
Innovation Solution
Implementing a device sharing module that uses sensors to detect user intent and authenticate users without manual input, allowing seamless switching and maintaining personalized interactive sessions based on user presence and context, while also securing content and deterring theft through user identifiable information management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual login and logout is required for device sharing, then user privacy and security are maintained, but user convenience and ease of operation deteriorate due to forgotten sessions and manual intervention requirements
Solution Approach 1:
The system performs automatic login and logout operations without requiring user intervention. The device autonomously detects user presence through sensors, automatically authenticates recognized users, and initiates logout when the user leaves, thereby maintaining security while eliminating manual operation requirements
Solution Approach 2:
The patent replaces manual mechanical actions (typing login credentials, pressing logout buttons) with sensor-based detection and automated system responses. Optical sensors, proximity sensors, and other detection mechanisms substitute for human hands and eyes, enabling automatic authentication and session management
2Reliability
If automatic logout is implemented after inactivity, then security is improved, but user frustration increases due to interrupted sessions
Solution Approach 1:
The system continuously monitors user presence through sensors and provides real-time feedback by maintaining or terminating sessions based on detected user state. When a user is detected to have left the device, the system responds by initiating logout, creating a closed-loop control system that adapts to user behavior without arbitrary time-based interruptions
Solution Approach 2:
The session management system transitions from static time-based logout to dynamic presence-based logout. The system adapts session state based on real-time sensor data about user presence, allowing sessions to be maintained as long as the user remains present and automatically terminated when the user leaves, regardless of duration
3Adaptability or versatility
If device sharing is enabled in unsupervised environments, then device accessibility and versatility improve, but security and user identification become problematic without manual login
Solution Approach 1:
The patent replaces manual credential input with sensor-based user detection systems. Optical sensors capture images for facial recognition, proximity sensors detect user presence, and other sensors automatically identify and authenticate users without requiring manual interaction, enabling secure access in unsupervised environments
Solution Approach 2:
The system creates digital copies of user identifiers through sensor data (facial images, voice patterns, behavioral biometrics) and uses these copies for automatic authentication. Instead of requiring physical presence of credentials like cards or tokens, the system captures and processes sensor-based copies of user identifying characteristics
4Adaptability or versatility
If multiple users can access the device simultaneously, then device sharing capability improves, but maintaining personalized sessions and securing content becomes complex
Solution Approach 1:
The system segments the device state into separate personalized sessions for different users. Each user has their own isolated session context with personalized content and settings, managed independently through automatic detection. When multiple users are present, the system divides attention and resources among separate user sessions rather than managing a single shared state

AI summary
In aspects of shareable devices, a shareable device has a memory to maintain identifiable information usable to identify users of the shareable device for subsequent reference. The shareable device implements a device sharing module that can receive the identifiable information about a user who initiates using the shareable device, and initiate an interactive session allowing a user to access the shareable device responsive to receiving the identifiable information about the user. The device sharing module can then communicate the identifiable information to an additional device that maintains the identifiable information for subsequent reference, and subsequently end the interactive session, thereby enabling the shareable device for use by a subsequent user. The device sharing module can also receive a disable command from the additional device to initiate disabling the shareable device.
