Trust Circle System for Selective Content Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer ecosystems lack an effective mechanism to establish and manage user-based trust levels for content sharing, leading to either unrestricted access or complete isolation, failing to ensure that sensitive information is shared only with intended parties.
Innovation Solution
An intelligent trust system that assigns and manages different levels of trust to user identities and devices, using tags to control access to specific content types, allowing users to customize trust levels for contacts and automatically screen communications based on predefined criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content sharing is opened to all individuals, then accessibility and sharing capability are improved, but security and trust control deteriorate
Solution Approach 1:
The system segments the contact list into multiple circles with different trust levels (e.g., family, friends, acquaintances). Each circle represents a segmented group with specific access permissions, allowing content to be shared selectively within appropriate groups rather than universally or not at all.
Solution Approach 2:
Different trust levels and access permissions are assigned to different circles of contacts. Each circle has localized quality characteristics (different levels of trust and access rights), enabling the system to provide appropriate access control tailored to each group rather than applying a uniform policy.
2Reliability
If content sharing is restricted to protect sensitive information, then security and trust control are improved, but accessibility and sharing capability deteriorate
Solution Approach 1:
The system provides dynamic access control where users can adjust trust levels and circle memberships as relationships evolve. Access permissions are not static but can be modified over time, allowing the system to adapt to changing trust relationships while maintaining security.
Solution Approach 2:
The circle-based trust system serves multiple functions: it enables content sharing, provides security control, manages contacts, and facilitates communication screening. This multi-functional approach allows the system to maintain reliability while supporting diverse sharing scenarios.
3Ease of operation
If automatic access is allowed to contacts, then ease of operation is improved, but security and authorization control deteriorate
Solution Approach 1:
Users perform preliminary actions by creating circles and assigning trust levels in advance. Contact information is pre-screened and organized into appropriate circles before actual content sharing occurs. This preliminary organization enables automatic access control based on pre-established trust relationships.
Solution Approach 2:
The system provides feedback mechanisms where users can review and adjust circle memberships and trust levels. Users receive information about who has access to their content and can modify permissions based on this feedback, maintaining authorization control while enabling convenient automatic access.
Data Source
AI summary
A user can assign a level of trust to other users to manage what content they may access or share. The user also assigns to each level of trust content type that may be accessed by users having that level of trust. The user then sends tags to his contacts indicating their level if trust, which are then presented by the contacts to gain access to the user-defined content.
