Just a tip on Metadata with EXIF when you are using Social Media.

Greetings,

I don't often post information on this regard but hopefully it may be of use to some. By default images generally taken on iPhone & Android (unless you have changed the default option of leaving the GPS data in) leave almost a digital trail of your location. You may or may not know this as EXIF Metadata. It is actually inside images you are probably sharing right now. That's where this post comes in.

Upload an image for yourself to: and examine the results for a better understanding.

Now you may or may not see the problem? But it is also the device your using and the GPS co-ordinates you were at, at the time of taking the photo/image with your camera. There are two ways of "stripping" the EXIF Metadata both of which are free (libre).

First for Android there is a great free Android application on the Google Play Store called Image Privacy

If you are a GNU or Linux user you can do this on the command line also. run "sudo apt-get install mogrify" (Sorry I'm a Debian Desktop guy so your install command might be yum).

To use this equally awesome libre tool run this

"mogrify -strip <file.jpg>"

And now you are not sharing so much nasty digital trail of yourself on the internet.

I hope this helps some.

Just a simple script to do it automagically, if used as a cron job in Debian/Ubuntu.

The file naming is wrong it should be metacleah.sh but works fine when running the script & using. Obviously tweaking it to your setup is the ideal way to use this bourne script.

Just as a sidenote, it's GNU+Linux, not GNU or Linux ;)

Mogrify is a command to be used to strip EXIF info from images. The name of the util is ImageMagick.

There are also Android and iOS apps (probably other mobile OS's too) that allow you to view and\or remove EXIF info.

There's also the "exif" command line utility, I use Arch Linux, you just need to have the AUR enabled and you can install it, the easiest way to do it would be to also enable yaourt, and then type

Code:
sudo pacman -Syu && yaourt exif


In my case it's the option number 9, I had this utility a long while ago, it's also available in Fedora with the RPM fusion repos; anyway, while it's something really basic I think a lot of people will find this useful.

This would be for Fedora

Code:
sudo yum update -y && sudo yum install exif


And btw, I think you meant a Unix or Linux user because GNU is not a kernel neither an OS. When I'm on FreeBSD I use a command line utility known as that, as exif.
