Shared Device Identity Manager for Personalized Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively manage identities of users on shared electronic devices, such as televisions, telephones, and personal computers, which are used by multiple users, leading to inconsistent and unsecured access to device preferences and privileges.
Innovation Solution
A shared device identity management system that includes a Shared Device Identity Manager (SDIM) to validate user identities and apply appropriate preferences and privileges based on individual or group affiliations, using mechanisms like Bluetooth, GPS, and manual input to manage identity claims and device affiliations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a shared device is used by multiple users without identity management, then device accessibility is improved, but user preference application deteriorates
Solution Approach 1:
The system segments user identification into distinct identity claims that can be independently validated and applied. Each user's identity is separated into verifiable claims (e.g., name, age, preferences) that can be individually managed and applied to the shared device, allowing multiple users to access the device while maintaining distinct preference profiles.
Solution Approach 2:
The patent introduces an intermediary identity management system that mediates between multiple users and the shared device. This intermediary validates identity claims, determines appropriate user identities, and applies corresponding preferences, serving as a bridge that enables both broad device accessibility and personalized user experience.
2Measurement precision
If identity validation is implemented on shared devices, then user identification accuracy is improved, but system complexity deteriorates
Solution Approach 1:
The patent creates a universal identity validation framework that can handle multiple types of identity claims (personal information, biometric data, device identifiers) through a single standardized process. This multi-functional approach improves identification accuracy while avoiding the need for separate complex validation systems for each identity type.
Solution Approach 2:
The system changes the parameter of identity validation from requiring complete user profiles to validating specific identity claims. By focusing validation on essential parameters (name, age, basic preferences) rather than comprehensive user data, the system achieves accurate user identification with reduced complexity.
3Measurement precision
If manual identity affiliation is used, then identity validation accuracy is improved, but user operation time deteriorates
Solution Approach 1:
The system performs preliminary identity validation by pre-verifying identity claims before users need to access the shared device. User identities are validated in advance and stored, so when users access the device, the system can quickly retrieve and apply their preferences without requiring time-consuming manual validation each time.
Solution Approach 2:
The patent implements self-service identity affiliation where users can automatically associate their identities with the shared device using pre-validated identity claims. The system autonomously validates claims and applies preferences without requiring manual intervention, reducing user operation time while maintaining validation accuracy through automated verification processes.
Data Source
AI summary
A device receives an identity claim associated with a user of a shared device, and determines whether the identity claim is valid. The device also determines one of an individual identification or a group identification to affiliate with the shared device when the identity claim is determined to be valid. The device further provides one or more preferences and privileges to the shared device based on the one of an individual identification or a group identification affiliated with the shared device.
