But how does the page know which user came in and which user owns  that page. I mean the page is display sheet. How does it know when I am logged in. that I am the owner and when some body other than me comes in, he is a visitor.

You have to store this relationship as well somehwere in the Database for ex.

An example could be that each pages' title is unique and you are maintaining the relationship in the DB like:

Page Title | User Id

Now on page load of each page you can check something like this:

protected void Page_Load(object sender, EventArgs e)
        {
            //Select userId from DB where title is Page.Title

            String UserIdDB = "";
            if (UserIdDB.CompareTo(User.Identity.Name) == 0)
            {
                //Don't store

            }
            else
            {
                //Store
            }

}
