If you post pictures you've taken with a smartphone on your blog, their embedded hidden metadata can break your anonymity. Samrtphones which includes GPS unit, such as the iPhone, automatically store the exact location where the picture was taken in the
EXIF metadata (which can be viewed with this
free EXIF viewer). This can endanger your privacy if the picture was taken at your home, for example. This
free program to remove EXIF data can be used to clean your pictures before posting them on your blog.
