Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems face difficulties in tracking licensing, chain of title, media rights, and ownership of documents, and identifying illegitimate copies, with watermarks and steganographic tags being inadequate.

Innovation Solution

A system using QR codes embedded in documents to track interest rights, which includes generating and updating codes based on changes in ownership or rights, and utilizing a blockchain to manage and verify these changes, ensuring legitimacy and authenticity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If watermarks or steganographic tags are used to track document ownership, then some protection in identifying documents is provided, but the tracking difficulty remains and the system complexity increases

Engineering Contradiction:

Improvedocument ownership tracking reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses QR codes as machine-readable copies that encode ownership information. Instead of embedding complex steganographic tags directly in the document, the system creates a separate QR code that can be scanned and verified, simplifying the tracking mechanism while maintaining reliability

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces a verification server as an intermediary between the QR code and the document ownership verification process. The QR code contains encoded information, and the server acts as a mediator to decode and verify the ownership claims, separating the tracking function from the document itself

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If QR codes are embedded in documents to track ownership changes, then ownership tracking efficiency improves, but the difficulty of detecting and measuring ownership changes increases

Engineering Contradiction:

Improveownership tracking efficiencyVSAvoidownership change detection difficulty

Core Design Contradiction:

ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements a feedback mechanism where scanning the QR code provides immediate feedback about the current ownership status. The system automatically detects ownership changes by comparing the QR code information with the document metadata, making ownership change detection simple and automated

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces complex manual detection methods with automated optical scanning and digital verification. Instead of requiring physical inspection or complex analysis, the system uses simple QR code scanning followed by automated server-based verification, dramatically simplifying the detection process

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A first redirect request is received. The first redirect request is based on a link to a document server in a first code embedded in a document. For example, the first code embedded in the document may be a QR code. A user is authenticated. The user has an interest right in the document. The interest right may be an ownership right to the document. A request to change the interest right in the document is received. In response to receiving the request to change the interest right in the document, a second code is generated based on the change in interest right in the document. The second code is embedded into a copy of the document. The copy of the document with the embedded second code is sent. For example, the copy of the document with the embedded second code is sent to a new owner of the document.
