I bought N9 second-hand a while ago and then I realized that the previous owner might track me down with this track&protect-app (t&p). I wasn't able to register my own account with this device so I'm pretty sure that the previous owner still holds his account. If I'm not able to get that t&p-account from him, I pondered that the least I can do is to blacklist N9 front camera. Just to get that comfort that no one is watching me over the Internet.

I have previously blacklisted modules in desktop-pc, but this handheld device looks a bit harder.

blacklist is of course in /etc/modprobe.d/blacklist.conf but how can I find out which module/driver is the front camera?

If you have any better solutions in mind feel free to share those..

... and I actually asked from the previous owner about this t&p-app but got no answer.
