Solution Overview
Problem
Inconsistent classification of sensitive documents across multiple reviewers in legal and business contexts leads to unauthorized or inadvertent disclosure, resulting in potential legal and reputational risks.
Innovation Solution
A computer-based method generates registration and production keys with digital fingerprints for sensitive documents, alerting users if there is a match between the two, thereby preventing unauthorized disclosure by monitoring and comparing these keys across different classification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple reviewers independently classify documents, then classification coverage increases, but classification consistency deteriorates
Solution Approach 1:
The system segments the classification task into independent reviewer operations while maintaining centralized coordination through digital fingerprinting. Each reviewer works independently on document segments, but the system tracks all classifications through unique document identifiers, enabling post-hoc consistency verification without restricting individual reviewer autonomy.
Solution Approach 2:
The system implements feedback mechanisms where classification decisions are tracked and compared across reviewers. When inconsistencies are detected through fingerprint matching, the system provides feedback to reviewers about conflicting classifications, enabling corrective action and improved future consistency while maintaining high classification coverage.
2Reliability
If documents are monitored for sensitive content, then disclosure prevention improves, but system complexity increases
Solution Approach 1:
Instead of monitoring entire documents, the system creates and monitors digital fingerprints (copies) of document identifiers. These fingerprints serve as proxies for the actual sensitive content, allowing comprehensive monitoring without the computational complexity of analyzing full document contents. The fingerprint matching system detects potential disclosures through these simplified representations.
Solution Approach 2:
The system introduces digital fingerprints as intermediary elements between the sensitive documents and the monitoring system. These fingerprints act as mediators that carry essential identification information without exposing the actual sensitive content, simplifying the monitoring architecture while maintaining effective disclosure prevention capabilities.
3Measurement precision
If digital fingerprints are generated and compared across all documents, then disclosure detection accuracy improves, but processing time increases
Solution Approach 1:
The system extracts only the essential identifying features of documents into compact digital fingerprints, separating this identification function from the full document content. This extraction allows rapid comparison and matching operations without processing the entire document, significantly reducing processing time while maintaining high detection accuracy through the preserved identifying characteristics.
Solution Approach 2:
The system transforms document identification from a complex multi-parameter problem into a simplified fingerprint parameter space. By changing the representation parameters from full document content to condensed fingerprint identifiers, the system enables fast comparison operations with high accuracy, resolving the trade-off between detection precision and processing speed.
Data Source
AI summary
A computer based method of protecting sensitive documents is provided, the method comprising identifying a first document, generating a registration key associated with the first document, identifying a second document, generating a production key associated with the second document, and producing an alert if a segment of the production key is identical to a segment of the registration key. For example, the registration key may comprise a digital fingerprint and registration metadata and the production key may comprise a digital fingerprint and production metadata, and the method may produce an alert of the digital fingerprint of the production key matches the digital fingerprint of the registration key.
