Using powers of two (?) to determine various access levels

I think there is a way to use powers of two or something similar to determine different levels. For instance, I have different access (different parts of my site), that different people should be able to access. I believe that by using division or modulus division there is a way to have a unique number for each situation. For instance, if someone was able to access areas 1, 3, and 4, the numbers would be divisible by a certain number for each, but not others. Can anyone guide me in the right direction? thanks
