Secure redaction
Blur and pixelate are visual effects: the pixels are still in the document. Secure redaction is different in kind. At export the covered pixels are flattened and removed, and the export is tested by trying to recover them from the file and from the document package.
- The original capture is never changed; the redaction applies to what leaves
- The tool is named for what it does, so that nobody mistakes a blur for a redaction
