Raise your hand if you've either participated in or managed a group of contract attorneys sitting in rows of cubicles (or "stations") redacting documents for production. Whether your tool of choice was a black marker or a cursor, I'm betting it was a thankless, tedious, pain-staking job and you hated it. Wouldn’t it have been nice if you could've taught the computer how to recognize the patterns of PII (private identification information) and have it make the redactions itself?
Well, guess what, Valora heard your anguished cries and we've built an AutoRedaction engine that rivals any group of manual redactors. With blazing speeds, impressive accuracy and astounding savings, our PowerHouseTM system literally autoredacts paper and ESI documents in seconds.
Capitalizing on our extensive experience with pattern-matching technology, Valora has built a custom software program that automatically determines the presence of sensitive PII, confidential or privileged information, and then redacts out that information on the image. AutoRedaction takes the form of a black block, with or without a representative stamp, such as "Redacted" or "Employee 123." Redactions can be made permanent, such as for production purposes, or kept temporary, with a technique for "lift and peek," when desired. Redactions can also be made to the underlying text, or on both text and image, if desired.
