关于 脱敏与涂黑 的常见问题
Can someone undo the black boxes to see the text underneath?
No! ScanOrbit uses true flattening redaction. The underlying pixels and text strings are permanently obliterated, so no software can reveal the hidden data.
Does this strip hidden metadata like author name and location?
Yes. Sanitized PDFs have all metadata streams purged for maximum security.
