File’s metadata are constantly trying to disclosure information about you. Metadata within a file could uncover a lot about your personal life. Unfortunately, cameras record too much information about every picture they take.
Why digital photos’ metadata can be dangerous:
Pictures love holding information such as the location where the photo was taken, date and time. People love sharing photos over the Internet. However, as you can see there’s a huge flaw over there. Even if you are sharing images only with your friends, that’s still insecure. Nowadays, data can become publicly available so easily. An experienced stalker(maybe a Private Investigator) could uncover your current location without a hitch. Additionally, images hold the author and the creator’s details. Windows usually are happy to add crucial info about your PC as a meta content at your files.
How to remove metadata from your digital photos:
If you are a Windows user that’s pretty easy. Simply select an image. Right click on it and the choose Properties. Afterwards, go to the Details tab and click the “Remove Properties and Personal Information”. Then, just select the properties that you wish to erase.
On the other hand, if you have access to a Linux machine you could try completely stripping metadata from your images. To do so, you will firstly need to install the exiftool. Use your distro’s package manager to download and install it. If for instance you are under Ubuntu try:
sudo apt-get install libimage-exiftool-perl
Afterwards, navigate to a folder with pictures of which you wish to strip their metadata and try:
# The * is called wildcard. Will erase metadata from every image in that directory
exiftool -all= *.jpg
# If you wish to erase the metadata from a specific image:
exiftool -all= filename.jpg
To sum up, I’d like to strongly suggest you make it habit – erasing metadata from every photo. It seems unwise to let metadata reside within your files. The reason is obvious..
