How accurate is PrizmDoc Viewer’s auto-redaction process? Is there any estimate of the percentage of matches that it will fail to redact?
If you’re performing auto-redaction as described in our documentation, then all matches for the input regular expression will be redacted in the final document. However, it’s difficult to express that confidence in the form of a percentage. PrizmDoc is subjected to a suite of automatic testing to ensure that its services are behaving as intended, including redactions. We never release a new version unless it passes 100% of those tests.
That being said, the primary way that inaccuracy could enter the system is if you’re attempting to redact scanned documents that have been OCRed. In this case, it’s a matter of your OCR software’s accuracy, rather than the accuracy of PrizmDoc’s redaction process. If the searchable text of the document doesn’t accurately reflect the visible text on the page (for example, if a smudged “discovery” is incorrectly recognized as “disccvery”), then the auto-redaction will be unable to recognize it due to the incorrect input it has been given. This isn’t a problem if the documents were not OCRed.
