概要
Metadata anonymization toolkit
履歴
mat2 is the second-generation Metadata Anonymisation Toolkit: a Python library and command-line utility for removing privacy-sensitive metadata from documents, images, archives, audio, video, and office files.
The README frames mat2 around a privacy threat model in which ordinary files disclose author names, companies, camera details, timestamps, and other metadata. It explicitly positions the tool as a successor to the first MAT project, thanks Google Summer of Code and Tails, and records Julien Voisin's 2018 copyright.
The public release stream includes 0.2.0 in July 2018 and later 0.14.x releases. The README describes three surfaces: the `libmat2` library, the `mat2` command-line tool, and a Dolphin service menu for KDE users.
mat2 reached a broader distribution footprint than many single-purpose privacy tools because metadata stripping is useful for activists, journalists, packagers, and privacy-conscious desktop users. The batch input records packaging across Homebrew, Debian, Ubuntu, Fedora, Arch, Alpine, MacPorts, and Nix.
The README points GUI users to Metadata Cleaner, which uses mat2 underneath. That relationship helped mat2 serve both terminal workflows and desktop privacy tooling without making the CLI carry a full GUI itself.
Typical CLI usage is `mat2 file...`, which writes cleaned copies such as `myfile.cleaned.png` rather than modifying originals in place by default. The README also documents `--show` to inspect detectable metadata, `--list` for supported formats, `--inplace`, dependency checks, archive-member policy, and a lightweight mode that trades completeness for less alteration of file content.
The README is careful about limits: absence of displayed metadata is not a proof that no metadata exists, especially for complex file formats. That makes mat2 a practical minimization tool rather than a formal sanitizer.
mat2 matters in package collections because it wraps a lot of file-format-specific cleanup behavior behind one small CLI. Its optional dependencies such as ExifTool, FFmpeg, Poppler, librsvg, and GdkPixbuf also make it a good example of a privacy tool whose packaging quality depends on distro integration.
For security-minded users, mat2 is a useful counterweight to the default behavior of office suites, cameras, and document exporters: it makes metadata review and removal scriptable.
