StegoGIS: A new steganography method using the geospatial domain

Ömer KURTULDU, Mehmet DEMİRCİ
2019 Turkish Journal of Electrical Engineering and Computer Sciences  
We develop a method called StegoGIS for hiding messages in geographic coordinates in the well-known binary of fast-moving objects and transmitting them secretly.  ...  We argue that StegoGIS offers a novel and practical secret communication method with minimal overhead.  ...  Finally, different domains can be tested over GIS data to increase the amount of secret data in the cover objects using a combination of geospatial and spatial coordinates.  ...
