Hi Friends,

How to implement form submit security other than using the captcha method ?

Please help
Thanks Rajeesh

You could use a honey pot. Essentially a form field that is hidden from display to the user and is purposely designed to be left empty. The thought is that when a bot comes along and spiders the form it will fill all the fields including the one supposed to be empty.

Lots of stuff has been written on their success rate.
