Docked Tablet Access Control for Locked Shared-Use Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as tablets, lock when inactive, preventing both authenticated and unauthenticated users from accessing functionality, limiting the ability of unauthenticated users to use basic features like music streaming or interacting with smart home devices.
Innovation Solution
A computing device is configured to enter a docked mode when connected to a docking station, allowing unauthenticated users to access certain functionalities like media playback and smart home control while remaining locked, with restricted access to personal data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device locks when inactive to prevent unauthorized access, then security is improved, but unauthenticated users cannot access basic functionality like media playback
Solution Approach 1:
The patent applies local quality by creating different access levels for different functionality types. Unauthenticated users are granted permission to access specific media-related functions (music, video, podcasts) while the device remains locked for other operations. This is achieved through a media permission system that selectively enables certain applications and features without providing full device access, thus maintaining security while enabling specific functionalities.
Solution Approach 2:
The patent segments device access into distinct permission categories: full authenticated access, partial unauthenticated media access, and completely locked state. The media permission mode separates media-related functionalities from other device functions, allowing independent control. This segmentation enables the system to grant targeted access to unauthenticated users for media playback while maintaining security restrictions for other operations.
2Reliability
If the device remains locked to protect personal data, then data security is improved, but unauthenticated users cannot interact with the device at all
Solution Approach 1:
The patent implements local quality by applying different security policies to different data and functionality types. Personal data remains protected and inaccessible to unauthenticated users, while media content and media-related functions are made accessible through the media permission system. This allows the device to adapt to multiple user types (authenticated and unauthenticated) simultaneously, providing appropriate access levels for each user category while maintaining data security.
Solution Approach 2:
The patent introduces dynamic permission management where the device can switch between different access modes based on authentication state. When a user is unauthenticated, the device dynamically enables media permission mode which allows media interaction. When authenticated, full access is granted. This dynamic adaptation enables versatile multi-user functionality while maintaining security boundaries.
3Reliability
If full authentication is required for all functionality, then security is improved, but usability in shared environments deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring media permission mode that allows unauthenticated users to access media functionality without requiring authentication. This preliminary permission setup enables immediate media playback and interaction in shared environments. When needed, the system can transition to requiring authentication for other functions, but media access remains readily available to all users through this pre-established permission pathway.

AI summary
Various techniques for directed to unauthenticated and authenticated users accessing functionality of a docked computing device. The techniques are directed to allowing unauthenticated users (e.g., family members, friends, . . . ) to access to selected functionality types provided by the computing device even though the tablet is locked. As an example, while the tablet is docked and locked, unauthenticated users can access selected functionality types provided by the computing device such as, but not limited to, the ability to listen to music, stream videos, ask for timers, set reminders, ask for facts from a virtual assistant, and the like.
