Shared Device Account Switching for Clean User Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IoT environments, shared devices registered with multiple accounts face conflicts in rights management, leading to data contamination and difficulties in applying AI services due to inconsistent user data usage records, and existing solutions rely on user adaptation rather than technical means.
Innovation Solution
An electronic device configures itself based on account-related information received from an external device, allowing temporary registration and configuration changes using account access information, enabling seamless switching between accounts while maintaining user experience and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a shared device is registered with multiple accounts, then device sharing capability is improved, but data integrity and security deteriorate due to conflicting rights management
Solution Approach 1:
The patent segments account access rights by creating separate right sets for different accounts. Each account receives a specific right set that defines what operations it can perform on the shared device, preventing conflicts while enabling sharing. The right management server distributes different right sets to different accounts based on predefined policies.
Solution Approach 2:
The patent introduces a right management server as an intermediary between multiple accounts and the shared device. This server manages the distribution and verification of right sets, acting as a mediator that ensures each account operates within its authorized boundaries, thereby maintaining data integrity while enabling multi-account access.
2Reliability
If conventional right management policies are used, then conflict prevention is improved through user adaptation, but technical automation deteriorates as conflicts are solved by learning rather than technical means
Solution Approach 1:
The patent implements preliminary action by pre-defining right sets and access policies before conflicts occur. The right management server distributes appropriate right sets to accounts in advance based on predefined policies, preventing conflicts before they happen rather than relying on users to learn and adapt after conflicts arise.
Solution Approach 2:
The patent incorporates feedback mechanisms where the right management server continuously monitors account access and device operations. When access requests are made, the server verifies rights in real-time and provides feedback by granting or denying access based on the distributed right sets, creating an automated closed-loop system.
3Adaptability or versatility
If data usage records are maintained in a shared device, then service personalization is improved, but data contamination occurs making AI service application difficult
Solution Approach 1:
The patent segments data usage records by account, ensuring that each account's usage data is separately tracked and stored. This segmentation prevents contamination between accounts while still enabling personalized services for each user based on their own usage patterns, which can be accumulated and analyzed without interference from other users' data.

AI summary
Methods and electronic devices are provided. Account access information is received, at an electronic device, from a external electronic device. The account access information is transmitted to a server. Account-related information about the external electronic device is received from the server. An account of the external electronic device is logged into based on the account-related information. A configuration of the electronic device is changed while logged into the account of the external electronic device.
