DESCRIPTION
The
Metadata Anonymisation Toolkit is a lib (with a CLI and a GUI)
created to anonymise file's
metadata. In essence, metadata answer who,
what, when, where, why, and how about every face of the data that are being
documented. They can be a
risk for privacy.

NOTES
MAT
only process metadata, it does
not handle file data.
Blame yourself if you are traced back because of the data of your files.
MAT is not perfect: In most of the cases, a forensic expert with a lot
of time
can trace back your document.
If you want absolute privacy, use plain-text.
BUGS
MAT does not handle watermaking/tattoos for now.
The --low-pdf-quality option may produce heavier PDF for very small files.
You should only use it for big files.
