When brainstorming a solution, Ricoh discovered that 99 percent of each document needed to be redacted. We decided on an approach called inverse redaction that draws around the information that doesn’t need to be redacted — the opposite of the normal process.
Another creative tactic: Instead of working on the spreadsheets within the TIFF images, where it’s difficult to line up rows and columns, why not work in the native Excel files? With this approach, we could search for the limited information that didn’t need to be redacted and then black out the remaining lines of information. It was much like the old paper and marker approach, yet digitized. Once complete, TIFF files were produced that were truly redacted and unalterable so no claims of information tampering could be raised by opposing counsel.
