Redaction Techniques: How We Accomplish Critical Tasks

BeyondReview’s redaction capability leverages advanced visual classification technology to evaluate sensitive data and redact based on either word or pattern matching or on redacting certain zones within groupings of visually-similar documents.  Called BeyondRedaction, this capability includes:

  • Automated grouping of documents to allow reviewers to learn the location of sensitive data.

  • Ability to target selection of sensitive data to be redacted based on either text values or page coordinates.

  • Defensible redaction of sensitive data.

This capability allow corporations to quickly and cost effectively redact sensitive data at a rate far exceeding traditional standard redaction technologies and processes.

BeyondRedaction: A Use Case Overview

12 bankruptcy courts redact over 412,000 documents in three months.

What is “BeyondRedaction”?

BeyondRedaction is a combination of technology and process that identifies data elements or document positions that need to be redacted to satisfy court orders or statutory and regulatory requirements. BeyondRedaction also provides an audit trail or log of each redaction that was made, including the terms that were redacted, the location coordinates of those terms and the reason for the redaction.


A report by Bankruptcy Court Special Master Karl Schieneman details how the BeyondRedactions technology enabled 12 bankruptcy courts to redact over 412,000 documents in under three months. The report notes that the productivity of the contract attorneys doing the redaction was almost 15 times normal redaction throughput, saving 19,000 hours of labor and hundreds of thousands of dollars of cost compared to manual approaches.


The bankruptcy judge overseeing the 12 cases required Garlock Sealing Technologies, Inc., to pay for the cost of redacting social security numbers and other PII prior to production and appointed Karl Schieneman as the special master to oversee the redaction and production process. After reviewing available options, Schieneman elected to use technology provided by BeyondRecognition.


BeyondRedaction technology is able to group documents based on visual similarity. This process enables reviewers to learn where the PII, trade secret, privilege, etc. is contained in the different document types and greatly speeds review and makes redactions far more consistent.

As part of its process, BeyondRedaction catalogs where the graphical elements or glyphs are located on each page. BeyondRedaction’s global glyph catalog associates text values with various glyphs so that the system knows the page coordinates for the various text values. This cataloging enables BeyondRedaction to redact based on either the text values that were used, or based on page coordinates even if there were no text values associated with the glyphs.

The “Differentiator” of BeyondRedaction.

Very few document collections have documents with 100% accurate text. BeyondRedaction’s ability to analyze and group documents based on visual appearance provides far greater assurance that all the terms that need to be redacted are in fact redacted.
