EXIF (Exchangeable Image File) data is metadata embedded in all photographs taken by digital cameras, tablets, etc. It includes very helpful information about shutter speed, F length, etc., but importantly for security purposes, date, time, & location based on GPS coordinates. But this information is also publically available if you upload your photos to a public space.
If you take a photo at your home, then your home's GPS location will be available to anyone who wishes to know where you live in your photo's EXIF data, which is probably not a welcome outcome. So stripping out that EXIF metadata will make your digital photos anonymous. Before uploading your digital photos, you should always review your photo's metadata using a EXIF data viewer to see that the available metadata info is not compromising.
