ASP user data - registration verification

We have an existing ASP form that captures User Data. See attached Zip. We need to add authentication code to make sure there are no duplicate registrations (or request. People are trying to register with variations in their name, address first and last name switches etc. We don't want that. We're looking to match: first & last name with the zip code, just the last name and the zip code, different names on the same address + zip code, name & address match with state, interpret the address and match it againt the zipcode (disect house number and match it against name & zip code) any other matches you may think of that can prevent people from registering twice. We would also like to add some safety for hacking if you're familiar with it, let us know ! ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
