How to revoke camera access for website not listed under Flash Player settings?

I gave a website (midomi) access to my camera and microphone on Safari, but when I tried revoking that access by going to my Mic and Camera Flash Player settings, the website was not listed with the other websites that have asked for access. When I visit the website now, it asks me for permission all over again, so it was likely only temporary access that I granted, but I'm still a bit paranoid. Can anyone confirm for me that the website no longer has access to my camera or microphone, even though I didn't specifically revoke it? Thanks!
