Metadata and privacy

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 on the web.

This is precisely the job of MAT2: getting rid, as much as possible, of metadata.

Requirements

  • python3-mutagen for audio support
  • python3-gi-cairo and gir1.2-poppler-0.18 for PDF support
  • gir1.2-gdkpixbuf-2.0 for images support
  • libimage-exiftool-perl for everything else

Please note that MAT2 requires at least Python3.5, meaning that it doesn't run on Debian Jessie,

Running the testsuite

$ python3 -m unittest discover -v

Supported formats

$ python3 ./mat2 -l
