Generate Turing Number for form submission to prevent automated regist

[whitesox12]

Hi,
How I want to have a script to generate and check a turing number. A turing number is a number the user has to read and copy in order to be able to validate a form. This avoids automated submissions. Just like when you register for yahoo mail etc it asks for this number to prevent automated registrations. Any help is appreciated.

Thanks

Thanks I am going to implement the same using JSP/Servlet and see how it goes.
