Serenissima writes "I've spent many hours building my Media Library in XBMC and scraping all the DVD Covers and Fanart. And I love it, I can pull up movies on any computer or device in the house. I played a movie for my son the other day so I could get some cleaning done without him being underfoot. I noticed shortly after that the sound coming from the other room was from a different movie than I played for him. I snuck up and watched for a few minutes and saw him use a trackpad to navigate to the stop and play buttons of different movies in his folder. I know it's only a matter of time before he realizes he can see all of the movies. I don't want him to have nightmares because he saw the T-1000 stab someone in the face. The quickest solution I can think is a screen saver with a password. It's mildly inconvenient to me, but would stop him from accessing anything. However, I remember how much more I knew about computers than my parents when I was a kid, and I have a feeling he's going to surprise me one day. There's a lot of ways out there to stop it, the way we do it now is to not let him watch anything unless we're there (but there are only so many times I can watch the same kid's movie). How do YOU guys find yourself dealing with the convenience of running your own server while keeping your media safe from prying eyes?"
