XR Device Database Segmentation for Secure Personalized AR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR) technologies lack efficient methods for acquiring and authenticating virtual objects, leading to all users receiving the same screen images without user identification, resulting in a lack of personalized experiences and security concerns.
Innovation Solution
The development of an extended reality (XR) device and method that separates databases during AR utilization, enhances user authentication security, and allows multiple users to access and utilize various AR information stored in different databases, enabling personalized and secure virtual object acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a common database is used for all users in AR applications, then the system complexity is reduced and ease of operation is improved, but user personalization is lost and security is compromised
Solution Approach 1:
The patent divides the common database into multiple user-specific databases, where each database stores AR information for a particular user. This segmentation enables personalized content delivery while maintaining secure access control, as each database is associated with authenticated user credentials.
Solution Approach 2:
The patent introduces an authentication module as an intermediary between users and databases. This module verifies user credentials and manages access rights, allowing the system to maintain both security and ease of operation by handling authentication transparently without requiring users to manually manage multiple databases.
2Reliability
If user authentication is implemented with multiple databases, then security is improved and personalization is achieved, but device complexity and authentication complexity increase
Solution Approach 1:
The patent implements a universal authentication module that handles multiple functions: user verification, database selection, and access control. This single multi-functional component manages the complexity of multiple databases without requiring separate authentication mechanisms for each database, thereby reducing overall system complexity.
Solution Approach 2:
The authentication system automatically performs user verification and database selection based on stored credentials, eliminating the need for manual database management by users. The system self-configures the appropriate database based on authenticated user identity, reducing operational complexity while maintaining security.
3Ease of operation
If the same screen images are provided to all users, then the ease of operation is maintained, but user experience personalization is lost
Solution Approach 1:
The patent applies local quality by storing different AR information in separate user-specific databases based on individual user characteristics and preferences. Each user receives customized screen images and virtual objects from their own database segment, enabling personalization while maintaining simple access through automatic database selection based on user identity.
Data Source
AI summary
A XR device and a method for controlling the XR device are discussed. The method includes accessing to a public DB (Database), generating a private DB based on key information of the public DB, where the public DB includes public AR (Artificial Intelligence) information, and the private DB includes private AR information and a whitelist, and acquiring the public AR information or the private AR information.
