Traceable Document Versions Using Imperceptible Content Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to trace document breaches, particularly malicious ones, as metadata can be easily removed, making it difficult to determine the source of unauthorized disclosure.
Innovation Solution
A system that modifies documents using natural language processing to generate unique versions for each recipient, allowing tracking through document content changes that are imperceptible to humans but detectable by processors, eliminating the need for metadata.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If metadata is used to track document ownership and transmission, then document tracing capability is improved, but security is worsened because metadata can be easily removed with widely available software
Solution Approach 1:
The patent extracts the tracking function from metadata and embeds it directly into the document content itself. The system modifies the actual text content of documents to include hidden tracking information, eliminating dependency on separate metadata structures that can be removed or manipulated.
Solution Approach 2:
The patent merges the tracking mechanism with the document content by integrating tracking data directly into the text itself. This combination ensures that tracking information cannot be separated from the document, as it becomes part of the document's actual content rather than an external metadata layer.
2Difficulty of detecting and measuring
If document content is modified to add tracking information, then traceability is improved, but document meaning may be changed
Solution Approach 1:
The patent applies local quality by making modifications only to specific, predetermined portions of the document content rather than altering the entire document. The system identifies and modifies only the necessary tracking elements while preserving the overall document meaning and integrity.
Solution Approach 2:
The patent uses partial action by modifying only the minimal necessary portions of the document content required for tracking, rather than extensively altering the entire document. This approach ensures traceability while minimizing impact on document meaning.
Data Source
AI summary
The invention relates generally to systems and methods for tracking a document by generating document variables, creating multiple new documents with different variables, and sending those new documents to different recipients. The document itself and the source of the document can be verified when a security leak occurs.
