Shared Device Permissions for Secure Smart Home Function Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart household device sharing methods lack adequate security measures, allowing incorrect operations on high-security devices to pose risks to family safety and property, such as improper use of door locks.
Innovation Solution
A method and apparatus for sharing devices that allow users to specify permissions for shared devices, enabling different users to access varying function properties, with a cloud server matching user permissions to device function labels and generating plug-ins to restrict or enable functionality based on assigned permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If device sharing is enabled without permission restrictions, then ease of operation is improved, but security and reliability deteriorate
Solution Approach 1:
The patent applies local quality by assigning different permission levels to different users for the same device. Each user receives customized permissions based on their role and needs, allowing some users to have full access while others have restricted access to specific functions only. This resolves the contradiction by maintaining ease of operation for authorized users while ensuring security through differentiated access control.
Solution Approach 2:
The patent segments device permissions into multiple levels and categories. Instead of providing all-or-nothing access, the system divides device functions into different permission tiers (e.g., view-only, basic control, advanced control). This segmentation allows the system to maintain security by restricting sensitive functions while still enabling convenient operation for permitted functions.
2Adaptability or versatility
If full device access is granted to shared users, then adaptability is improved, but harmful factors increase
Solution Approach 1:
The patent implements local quality by granting different levels of adaptability to different users. Each user receives permission levels tailored to their specific needs and trust level. For example, a family member might have full access to all device functions, while a service technician might only have access to specific diagnostic functions. This approach maintains versatility for authorized users while minimizing security risks through targeted permission assignment.
Solution Approach 2:
The patent applies preliminary anti-action by proactively restricting access to harmful or sensitive functions before they can be misused. The system pre-configures permission levels that automatically prevent users from accessing functions that could pose security risks. This preemptive approach blocks potential harmful actions while still allowing legitimate device usage.
3Reliability
If permission management is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by creating a standardized permission management framework that works across multiple devices and user types. The same permission structure and management mechanisms are reused throughout the system, reducing the need for device-specific configurations. This universal approach maintains security while minimizing complexity by avoiding redundant permission management logic.
Solution Approach 2:
The patent implements preliminary action by pre-configuring permission templates and default permission levels for common device types and user roles. Instead of requiring administrators to manually configure permissions from scratch for each device-user pair, the system provides pre-established permission frameworks that can be quickly applied and customized as needed. This reduces the complexity of permission management while maintaining security.

AI summary
Embodiments of this application provide a method and an apparatus for sharing a device. The method is: A first electronic device displays a first interface, where the first interface includes N to-be-shared devices; the first electronic device receives an operation that a user selects a target device and a target user, and displays a second interface, where the second interface includes a plurality of options, different options in the plurality of options correspond to different use permissions, and different use permissions allow the target user to use different function properties; the first electronic device receives an operation that the user selects a target option from the plurality of options and an operation that the user determines to share the target device with the target user by using a use permission corresponding to the target option.
