Solution Overview

Problem

Existing systems for processing multimedia documents lack granular permission control, allowing users to selectively manage access and processing of specific segments within documents, which is essential for secure and controlled sharing and editing of multimedia content.

Innovation Solution

A method and system that assign granular permissions to segments of multimedia documents, enabling users to control access, sharing, and processing of specific parts, allowing different permissions for different users or groups, and supporting hierarchical permission schemes for advanced processing tasks like emotion recognition and keyword spotting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If granular permission control is implemented for specific segments of multimedia documents, then data privacy and security are enhanced, but device complexity increases

Engineering Contradiction:
Improvedata privacy and securityVSAvoidpermission management system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the multimedia document into discrete segments (e.g., time intervals in audio, regions in images) and assigns independent permissions to each segment. This segmentation allows fine-grained control over access rights, enabling users to access only specific portions of the document based on their permission level, thereby enhancing security without requiring system-wide complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different segments of the multimedia document are assigned different permission attributes (e.g., read-only, edit, delete, share) based on local requirements. The system manages these localized permissions through a structured permission object that associates specific segments with their respective access control attributes, achieving targeted security without overwhelming complexity

Inventive Principle:
Principle #3Local quality

2Measurement precision

If hierarchical permission schemes are implemented for advanced processing tasks, then processing control precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveprocessing control precisionVSAvoiduser interface complexity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent introduces a hierarchical dimension to permission management by organizing permissions into levels (e.g., document-level, segment-level, task-level). This dimensional structure allows users to navigate and manage permissions through a layered interface, making the complex hierarchical control more manageable and easier to operate while maintaining precise control over processing tasks

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
