When signing up for a domain you need to provide details for various contacts. Registrant, technical contact, administrative contact, etc. They can all be the same person. The details are things like name, address, email and phone number. Those are usually the details that will be public in the whois records. Supposedly they "must" be accurate, although some services are more strict about this than others. I hear Godaddy will suspend your account and charge you $70 if they find you've faked something in your registration details. Some companies will put their details in there rather than yours, but in effect this can mean they can claim they own the domain if there's ever a legal dispute over it.

If you want to grab that domain though, I'd suggest you get in quick before someone sees your idea and registers the name themselves with the aim of selling it back to you for a profit. That practice is a bit too common unfortunately.
