SRTM is the satellite data that all terrain data is taken from. If you use 
Terrain data, you are using SRTM data, or derived, which obviously has the same

Technically, given enough time, fake random terrain data could be generated.

No, like most geo spacial data, the governments that release it tend to have 
their own license.
