I don't want others to see the live presentation or the file name being cast.. Also I don't want them to be able take over the chromecast if its in use..
Yes, if I'm casting a YouTube video and my wife connects to the same Chromecast, she'll see exactly what I'm watching as well as the playback position.
With the right application you can probably get information about what's being cast regardless of what application is casting.
Chromecast, is a consumer device designed for ease-of-use on a home network. It's very loose on the privacy, even considering the market, IMO.
suggested, you can control access by putting Chromecast on separate networks, whether that's via separate APs or via VLANs, it depends on how your network is configured. If you go the VLAN route, make sure to enable Multicast support on the VLAN but not multicast routing.
