關於此工具
Deep Metadata Sanitizer is your ultimate defense against metadata leaks and hidden tracking. Simply drawing black boxes over visible text in PDF files is not enough to protect commercial secrets.
This tool scans the PDF binary structure to completely erase author info, creator software, editing logs (XMP Metadata), proprietary PieceInfo caches, and OCG optional content groups (often used for invisible watermarks).
It also rewrites the cross-reference tables (xref) completely, discarding all incremental update blocks to ensure that deleted or modified historical data cannot be restored.
使用場景
