This is a great program used to help protect your privacy.
Metadata consists of information that characterizes data. Metadata is used to provide documentation for data products. In essence, metadata answers who, what, when, where, why, and how about every facet of the data that is 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 that information on the web.
MAT can only remove 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 a format that does not contain any metadata, or better yet, use plain-text.
These are the formats supported to some extent:
Portable Network Graphics (PNG)
JPEG (.jpeg, .jpg, …)
Open Document (.odt, .odx, .ods, …)
Office Openxml (.docx, .pptx, .xlsx, …)
Portable Document Fileformat (.pdf)
Tape ARchive (.tar, .tar.bz2, .tar.gz)
MPEG Audio (.mp3, .mp2, .mp1, .mpa)
Ogg Vorbis (.ogg)
Free Lossless Audio Codec (.flac)
The President of the United States and his birth certificate would have greatly benefited from software such as MAT.
You can install MAT with this terminal command:
sudo apt-get install mat

I am a linux user for over 10 years and Ubuntu linux is my only operating system. I originally made the jump from Windows to Ubuntu and open source back in early 2007 (using Ubuntu 6.10) for privacy and virus concerns.
