Manipulating stored geocoordinates in cellphone photos
Programming Snapshot – Go Geofuzzer
Mike Schilli loves his privacy. That's why he's created a Go program that adds a geo-obfuscation layer to cellphone photos before they are published on online platforms to prevent inquisitive minds from inferring the location.
If you sell your stuff online, you might overlook the potential risk of sales-promoting cellphone photos revealing highly sensitive private information. When you take a picture of the goods at home with your cellphone, the image file may also contain the geodata with which the private address can be determined to within a few yards.

That's why the self-written Go program in this issue adds a geo-obfuscation layer to image files to make sure that the geocoordinates are randomly blurred.
