NAME¶

MAT - Metadata Anonymisation Toolkit

SYNOPSIS¶

mat [options] files

mat-gui

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.

-a, --add2archive

-b, --backup

-c, --check

-d, --display

-l, --list

List all supported fileformat

-L, --low-pdf-quality

-v, --version

Display version and exit

EXAMPLES¶

mat --display mydocument.pdf

Display the mydocument.pdf's harmful metadata

mat --check *.jpg

Check all the jpg images from the current folder

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.
