Solution Overview

Problem

Existing systems struggle to efficiently manage and distribute informational content across disparate systems while ensuring access is controlled based on user hierarchy and resource availability, leading to inefficiencies and unauthorized data distribution.

Innovation Solution

A system comprising a plurality of displays, computing devices, and a system server that determines user hierarchy status and resource availability to selectively distribute modified or unmodified data sets, using machine learning models to manage content distribution and enforce access controls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If content is distributed across disparate systems without hierarchy-based access control, then distribution efficiency is improved, but unauthorized access and security risks increase

Engineering Contradiction:

Improvecontent distribution efficiencyVSAvoidaccess control security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces a server as an intermediary component that mediates between content sources and display devices across disparate systems. This server implements hierarchy-based access control logic, evaluating user credentials and hierarchy levels to determine whether content distribution requests should be authorized. This intermediary layer enables efficient automated distribution while maintaining security through centralized control.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the parameter of access control from traditional authentication to hierarchy-based authorization. By evaluating user hierarchy levels, credential types, and system-defined hierarchy thresholds, the system dynamically determines content distribution permissions. This parameter change enables both efficient automated decision-making and robust security control across multiple disparate systems.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If hierarchy-based access control is implemented across all systems, then unauthorized access is prevented, but system complexity increases

Engineering Contradiction:

Improveaccess control securityVSAvoidsystem architecture complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal hierarchy-based access control mechanism that can operate across multiple disparate systems and content types. The server evaluates various credential types (user credentials, device credentials, system credentials) against a unified hierarchy threshold model, providing multi-functional security control without requiring separate access control implementations for each system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system incorporates feedback mechanisms where the server continuously evaluates user hierarchy status against required thresholds and adjusts content distribution decisions accordingly. This automated feedback loop simplifies the system architecture by replacing complex manual access control configurations with dynamic, criterion-based automated decisions.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If user hierarchy status is evaluated for every content request, then access control accuracy is improved, but processing time increases

Engineering Contradiction:

Improveaccess control accuracyVSAvoidrequest processing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary evaluation of user hierarchy status and credentials before content distribution decisions are made. By pre-establishing hierarchy thresholds and credential validation rules in the server, the system can quickly determine access permissions without extensive real-time processing, thus maintaining high accuracy while reducing processing time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual or mechanical access control review processes with automated electronic evaluation mechanisms. The server automatically evaluates user credentials, determines hierarchy status, and compares against thresholds using computer-executable instructions, significantly reducing processing time while maintaining or improving accuracy compared to manual review processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A content management system for customizing and controlling data distribution is disclosed. Data items can be customized and dispersed to disparate reception terminals according to various control mechanisms where they can convey relevant information to local or remote stakeholders. Data items can be integrated into existing data distribution structures in real time according to applicable control mechanisms and distribution protocols. Data resources can be efficiently used in distributing data under predefined and configurable conditions. Control mechanisms and distribution protocols can be determined based on an interested user's recognized status within the system. Design of the distribution system allows for informed delivery of essential information in a controlled and automated fashion such that users can interact with the system in receiving or distributing current and relevant information across the distribution network for others to access.
