Multi-Layer Document Redaction via Source Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional software applications for document processing are limited in automatically redacting content across multiple layers of a document, requiring manual intervention to achieve uniformly redacted results, especially in complex documents like multi-layered schematic diagrams.
Innovation Solution
A content modifier process that identifies and redacts content in a source layer and automatically applies corresponding redactions in related layers based on proximity or logical relationships, allowing for uniform redaction across multiple layers without manual intervention.

Engineering Contradiction Analysis
1Extent of automation
If conventional redaction tools are used to redact content in multi-layered documents, then individual layers can be redacted manually, but the process requires extensive manual intervention for each layer and is time-consuming
Solution Approach 1:
The patent applies the copying principle by creating a redaction template from the source layer that can be automatically applied to multiple target layers. The redaction region identified in the source layer is copied and overlaid onto corresponding areas in target layers, enabling automatic redaction across multiple layers without manual intervention for each layer.
Solution Approach 2:
The patent implements preliminary action by first identifying and redacting content in the source layer to create a redaction template before applying redactions to target layers. This preliminary redaction in the source layer establishes the basis for automatic redaction in subsequent layers, eliminating the need for manual redaction in each layer.
2Productivity
If manual redaction is performed in each layer of a multi-layered document, then complete redaction coverage is achieved, but the time and effort required increases significantly
Solution Approach 1:
The patent merges the redaction operations across multiple layers by using a single redaction template derived from the source layer. Instead of performing separate manual redaction operations for each layer, the system combines them into one automated process where the template is applied uniformly across all target layers, dramatically improving productivity and reducing time loss.
Solution Approach 2:
The redaction template serves as a universal tool that can be applied to multiple different layers simultaneously. The same template identifies and redacts corresponding content across various layers, making the redaction process multi-functional and eliminating the need for layer-specific manual operations.
3Manufacturing precision
If uniform redaction areas are applied across all layers, then consistent redaction results are achieved, but content that should remain visible may be incorrectly redacted
Solution Approach 1:
The patent applies local quality by allowing the redaction template to be selectively applied only where corresponding content exists in target layers. The system evaluates each target layer locally to determine whether content should be redacted based on the overlay match, rather than applying uniform redaction across entire layers. This ensures accurate redaction of relevant content while preserving content that should remain visible.

AI summary
A system redacts content in a multi-layered document by executing a content modifier process that redacts a first portion of content in a source layer and then automatically redacts related content in at least one target layer. The content modifier process overlays the source redaction region on corresponding areas of other layers in the document to identify target redaction regions in those other layers that contain target content. In turn, the content modifier process automatically identifies and redacts the target content within target redaction regions.
