Solution Overview

Problem

Collaboration systems lack support for access control techniques to control and enforce permissions to access, modify, or interact with software domain resources in accordance with the attributes shared among users associated with certain persona types.

Innovation Solution

A collaboration system that enables users associated with different persona types to create and share software domain resources, using fine-grained access controls and different levels of resource aggregation, allowing users to collaborate while enforcing access permissions based on persona types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If collaboration systems enable users to share and access software domain resources, then collaboration efficiency is improved, but access control and security requirements increase complexity

Engineering Contradiction:

Improvecollaboration efficiencyVSAvoidaccess control complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The access control system segments permissions by persona type (service consumer vs. service provider) and resource aggregation level (global vs. specific). This segmentation allows the system to manage complex access controls through structured categories rather than individual user-level permissions, reducing overall system complexity while maintaining fine-grained control capabilities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The collaboration system implements a universal access control mechanism that handles multiple access scenarios through a single framework. The system universally applies persona-type-based permissions across all resource types and access patterns, eliminating the need for separate access control implementations for different collaboration scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If the system enforces fine-grained access controls based on persona types, then security is improved, but ease of operation for users decreases

Engineering Contradiction:

Improveaccess control securityVSAvoiduser operation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Users automatically receive appropriate access rights based on their persona type without needing to manually configure permissions. Service consumers and service providers are automatically granted access to resources according to their predefined persona characteristics, eliminating the need for users to navigate complex permission settings while maintaining strong security controls.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system changes the access control parameters from individual user-level permissions to persona-type-level attributes. Instead of managing complex user-specific permission sets, the system manages simpler persona parameters (service consumer vs. service provider) that automatically determine access rights, simplifying both security enforcement and user operation.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If the system supports multiple persona types with different access permissions, then adaptability to different user roles is improved, but device complexity increases

Engineering Contradiction:

Improvepersona type adaptabilityVSAvoidaccess control system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The access control system uses a universal persona-type-based framework that adapts to different user roles through a single mechanism. The same persona-type permission model handles access control for both service consumers and service providers, as well as for different resource aggregation levels, reducing the need for multiple specialized access control systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system manages adaptability by changing from managing individual user permissions to managing persona type parameters. The access control logic operates on high-level persona parameters (consumer/provider distinction) rather than detailed user characteristics, allowing the system to adapt to different roles through simple parameter changes rather than complex configuration.

Inventive Principle:

Principle #35Parameter changes

AI summary

In some implementations, a collaboration system may receive, from a first client device, a first request to create a software domain resource associated with a consumer persona type and a service consumer user identity, wherein the software domain resource is associated with access control information that indicates one or more service provider user identities, associated with a provider persona type, that have permission to access the software domain resource. The collaboration system may receive, from a second client device associated with a service provider user identity, a second request to access the software domain resource. The collaboration system may provide, to the second client device, information that indicates whether the second request to access the software domain resource is granted or rejected based on the access control information associated with the software domain resource and the service provider user identity associated with the second client device.
