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.
