Solution Overview

Problem

Digital content owners face challenges in preventing piracy without affecting authorized distribution and use, as existing digital rights management systems are not effective in discouraging unauthorized access and use of digital content.

Innovation Solution

Implementing a method to control the throughput rate of digital content access by an accessing system, where the throughput rate is associated with information related to the digital content, allowing for delayed pre-processing operations and storage system-controlled data release, thereby discouraging high-speed access that could facilitate piracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing digital rights management systems are used to prevent piracy, then content protection is attempted, but they fail to effectively discourage unauthorized access and use

Engineering Contradiction:
Improvecontent protection effectivenessVSAvoidimplementation effectiveness
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent changes the parameter of data transfer rate from unrestricted to controlled, implementing throughput rate limiting as a new parameter to govern digital content access. This parameter change transforms the DRM approach from relying on complex authorization protocols to a simpler rate-based control mechanism that effectively discourages piracy by making unauthorized copying as inconvenient as authorized use.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If high-speed data access is allowed for digital content, then authorized distribution efficiency is improved, but piracy facilitation risk increases

Engineering Contradiction:
Improvedata access speedVSAvoidpiracy risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic throughput rate control that adapts to different access scenarios. The system dynamically adjusts the data transfer rate based on authorization status and content type, allowing high-speed access for authorized distribution while automatically limiting speed for unauthorized access attempts, thus resolving the contradiction between productivity and piracy prevention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms that monitor data access patterns and adjust throughput rates accordingly. By continuously monitoring transfer rates and detecting anomalies that suggest unauthorized copying, the system provides real-time feedback control that maintains high productivity for legitimate use while preventing piracy without requiring complex pre-authorization protocols.

Inventive Principle:
Principle #23Feedback

3Reliability

If throughput rate control is implemented to prevent piracy, then unauthorized copying is discouraged, but authorized distribution may be affected

Engineering Contradiction:
Improvepiracy preventionVSAvoidauthorized access convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies partial action by implementing throughput control only at the storage system level for digital content, while leaving higher-level authorized distribution channels unaffected. This partial application of rate limiting ensures piracy prevention at the source without interfering with authorized distribution systems that operate at different layers of the data access hierarchy.

Inventive Principle:
Principle #16Partial or excessive action
