Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current software programs for electronic document redaction provide limited security, governance, and traceability, leading to potential leakage and exposure of sensitive information.

Innovation Solution

A document management system and application that uses a secure distribution list (SDL) to identify and redact sensitive content, generating role-specific child documents with encryption and customizable permissions, ensuring secure distribution and compliance with regulations like FOIA.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional redaction software generates black box redacted documents, then redaction is achieved, but security infrastructure is weak and traceability is lost

Engineering Contradiction:

Improvedocument securityVSAvoidsecurity infrastructure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the document into multiple versions, each tailored to specific recipient roles. Instead of a single redacted document, the system creates customized document variants where different sensitive portions are redacted based on recipient authorization levels, thereby maintaining security without requiring complex infrastructure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary redaction and segmentation before document distribution. By pre-processing the document to create role-specific versions with appropriate redactions already applied, the system eliminates the need for complex security infrastructure at the recipient end, as the security measures are embedded in advance.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If all sensitive information is redacted from a document, then confidentiality is maintained, but necessary information for different recipients is lost

Engineering Contradiction:

ImproveconfidentialityVSAvoidrecipient-specific access

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by making different portions of the document have different levels of accessibility based on recipient roles. Each recipient receives a version where redactions are applied locally to specific segments relevant to their authorization level, rather than uniformly redacting all sensitive information. This allows each recipient to access the appropriate level of detail for their needs while maintaining overall confidentiality.

Inventive Principle:

Principle #3Local quality

3Productivity

If a single redacted document is distributed to all recipients, then distribution is simple, but traceability and governance are lost

Engineering Contradiction:

Improvedocument distributionVSAvoidtraceability

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system implements feedback mechanisms by tracking which recipient receives which document version and monitoring access patterns. This feedback loop enables the system to maintain traceability of document distribution and usage, allowing governance and audit capabilities while still enabling efficient distribution through automated role-based document generation.

Inventive Principle:

Principle #23Feedback

4Reliability

If manual redaction processes are used, then security control is maintained, but time consumption and inefficiency increase

Engineering Contradiction:

Improvesecurity controlVSAvoidredaction processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system enables self-service by automatically generating role-specific redacted documents based on predefined authorization rules and recipient profiles. The system autonomously determines which portions to redact for each recipient without requiring manual intervention, thereby maintaining security control through automated policy enforcement while dramatically reducing processing time.

Inventive Principle:

Principle #25Self-service

AI summary

In one aspect of the present disclosure, a method includes determining an electronic document to be secured for distribution to a distribution list. The method also includes selecting a first portion of the document to be associated with a first recipient from the distribution list. The method further includes generating a redacted electronic document. The first portion of the document is removed from the document. The method includes encrypting the redacted electronic document with an encryption key associated with the first recipient. Additionally, the method includes transmitting the redacted electronic document that was encrypted to a document management system for access by the first recipient from the distribution list.
