Description-en: Metadata anonymisation toolkit v2
Metadata consist of information that characterizes data. Metadata are
used to provide documentation for data products. In essence, metadata
answer who, what, when, where, why, and how about every facet of the
data that are being documented.
.
Metadata within a file can tell a lot about you. Cameras record data
about when a picture was taken and what camera was used. Office
documents like PDF or Office automatically adds author and company
information to documents and spreadsheets.
.
Maybe you don't want to disclose those information.
.
mat2 only removes metadata from your files, it does not anonymise their
content, nor can it handle watermarking, steganography, or any too
custom metadata field/system.
.
If you really want to be anonymous, use file formats that do not contain
any metadata, or better: use plain-text.
.
Formats supported to some extent are:
- Audio Video Interleave (.avi)
- Electronic Publication (.epub)
- Free Lossless Audio Codec (.flac)
- Graphics Interchange Format (.gif)
- Hypertext Markup Language (.html, .xhtml)
- Portable Network Graphics (PNG)
- JPEG (.jpeg, .jpg, ...)
- MPEG Audio (.mp3, .mp2, .mp1, .mpa)
- MPEG-4 (.mp4)
- Office Openxml (.docx, .pptx, .xlsx, ...)
- Ogg Vorbis (.ogg)
- Open Document (.odt, .odx, .ods, ...)
- Portable Document Fileformat (.pdf)
- Portable Pixmap Format (.ppm)
- Scalable Vector Graphics (.svg)
- Tape ARchive (.tar, .tar.bz2, .tar.gz, .tar.zx)
- Torrent (.torrent)
- Waveform Audio (.wav)
- Windows Media Video (.wmv)
- ZIP (.zip)
.
mat2 provides a command line tool, and graphical user interfaces
via a service menu for Dolphin, the default file manager of KDE, and
an extension for Nautilus, the default file manager of GNOME.
