Dynamic Privilege Enforcement for Data Collaboration Sessions

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems fail to dynamically enforce privileges during data collaboration sessions among multiple devices, leading to inconsistent and unmanaged access and recording capabilities.

Innovation Solution

The method involves detecting participants and their corresponding group names, selecting privileges based on these groups, and applying them to ensure controlled data access and recording permissions during collaboration sessions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dynamic privilege enforcement is implemented during data collaboration sessions, then data security and access control are improved, but system complexity and processing overhead increase

Engineering Contradiction:

Improvedata securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system pre-establishes privilege profiles and group associations before data collaboration sessions begin. Participant groups and their corresponding privileges are configured in advance, allowing the system to quickly enforce access controls during sessions without real-time complex decision-making, thus improving security while managing system complexity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary privilege enforcement mechanism that mediates between participants and data resources. This intermediary layer handles the complex privilege checking and enforcement logic, isolating the complexity from both the data protection layer and the user interaction layer, thereby improving security without proportionally increasing overall system complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple participant groups with different privileges are supported, then adaptability and customization are improved, but device complexity and management difficulty increase

Engineering Contradiction:

Improveprivilege customizationVSAvoidmanagement complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments participants into distinct groups with assigned privilege profiles. Each group has predefined access rights and recording permissions, allowing flexible customization of privileges for different participant categories while simplifying management through group-based rather than individual-based control, thus achieving high adaptability with manageable complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates universal privilege profiles that can be applied across multiple participants and sessions. These profiles serve multiple functions by simultaneously controlling data access, recording permissions, and collaboration capabilities for entire groups, thereby achieving extensive adaptability without proportionally increasing management complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

In one embodiment, the methods and apparatuses detect a first participant wherein the first participant corresponds with a primary group name; identify a profile based on the primary group name; detect a second participant; identify a secondary group name based on the second participant; select a privilege within the profile based on the secondary group name; and apply the privilege to the first participant and the second participant.
