Making a controller one console specific?

Guys, I have two ps3s in the house, the family one (80gig fatty) and one I bought for myself recently (slim). Our house is relatively small and the problem is whenever someone powers up the 80 gigger, mine activates as well.

This morning the family was watching a bluray in the living room, and I was about the house, cleaning and moving things. The movie ended, and after wrapping up helping a bit in the kitchen, I went to my room for a minute and noticed my ps3 was on. It was no doubt turned on when my family started their movie, and fortunately Up isn't very long, so it wasn't left on for long. But still, I turned on my tv and I got the Press-Start title screen for RE5.

Anyway, our setup is pretty small, so is there a way to have one controller work only on one ps3, or something that would stop this from happening? I'm nervous that one night they'll watch a movie, I'll be out of the house, and my ps3 will be on for hours and hours on end.
