Metadata Visibility Component for Mobile Content Filtering

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current Enterprise Information Management (EIM) systems primarily control user access rights using access control lists (ACLs), which do not effectively manage visibility of content on mobile devices based on metadata properties, leading to inefficient content retrieval and display.

Innovation Solution

A method and apparatus that determine a visibility component from metadata values and compare it to a visibility-affecting feature of a mobile device, allowing objects to be retrieved and displayed only if the feature corresponds to the visibility property, using location, network type, application type, or ownership as visibility-affecting features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If access control lists (ACLs) are used to control user access rights, then security is maintained, but visibility management of content on mobile devices based on metadata properties is ineffective

Engineering Contradiction:

ImprovesecurityVSAvoidvisibility management capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments access control into two distinct mechanisms: traditional ACLs for authentication/authorization and a new visibility component for content visibility management. This allows ACLs to maintain security while the visibility component handles metadata-based visibility control, resolving the contradiction by dividing functions into specialized parts.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The visibility component acts as an intermediary between the EIM system and mobile device display. It receives metadata from objects, determines visibility based on mobile device features, and controls what objects are displayed. This intermediary layer enables sophisticated visibility management without compromising the security provided by ACLs.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If all objects are retrieved and displayed on mobile devices, then complete information access is provided, but efficiency is reduced due to display of irrelevant content

Engineering Contradiction:

Improveinformation completenessVSAvoidcontent retrieval efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

Instead of retrieving all objects, the system applies partial action by selectively retrieving only those objects that match the mobile device's visibility criteria. The visibility component filters objects based on metadata properties and device features, retrieving only the relevant subset needed for efficient display while maintaining information completeness for authorized content.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system changes the parameter of object retrieval from unconditional (all objects) to conditional (visibility-based filtering). By introducing visibility properties as filtering parameters, the system efficiently retrieves only relevant objects while maintaining complete information access for content that should be visible, thus improving productivity without losing necessary information.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If metadata-based visibility control is implemented for mobile devices, then relevant content filtering is improved, but system complexity increases

Engineering Contradiction:

Improvecontent relevanceVSAvoidsystem architecture

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The visibility component is designed as a universal mechanism that works across different object types and mobile device contexts. It uses a standardized approach with visibility properties and device feature detection that can be applied uniformly throughout the EIM system, reducing the need for separate complex implementations for different scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements self-service through automatic detection of mobile device features and automated comparison with object visibility properties. The visibility component autonomously determines which objects to display without manual intervention, reducing operational complexity while improving content relevance. The system self-manages the filtering process based on predefined metadata and device characteristics.

Inventive Principle:

Principle #25Self-service

AI summary

The invention relates to determining a visibility component from a metadata value of an object, determining a visibility-affecting feature of a mobile device using the information management system, and retrieving the object to a display view of the mobile device, if the determined visibility-affecting feature corresponds to a value of a visibility property of the visibility component. The invention further relates to an apparatus, and a computer program product that perform the method.
