What is a secure way to stream video?

Typically a drone uses WiFi to stream the live feed from your mounted camera to the controller. WiFi brings up huge security issues (it’s more easily hackable, geolocation is an issue, etc)

Are there any more “secure” ways that the drone industry is aware of? For example, I could run my Pixhawk off my 915MHz transmitter if I didn’t have video, but because I do, I need wifi?
