The "Black Box" Mistake
A common rookie mistake in document security is using a drawing tool to place a black rectangle over sensitive text. It looks safe, right?
Wrong. The text underneath that black rectangle is still there. Anyone can simply copy-paste the "hidden" text into Notepad, or just delete the black rectangle! This has led to massive data leaks in government and legal proceedings.
True Redaction
True redaction is a destructive process. It involves three steps:
- Identification: You select the area to remove.
- Sanitization: The software dives into the code of the PDF and physically deletes the text/image data in that coordinate space.
- Masking: A black box is drawn over the empty space to indicate text was removed.
With PDFSense Redaction, once you save, the data is gone forever. No hacker, specialized software, or trickery can bring it back because it simply doesn't exist in the file anymore.
