Chromecast shows up on all devices on network

Is there anyway to lock chromecast to 1 device? Anyone on the network can cast from there phone/tablet.

At this time there seems to be no way to restrict unless you lock down your WiFi and don't share the password. I do agree Google needs to add a Chromecast administration function in the future.
