Form flooding protection

I'm looking for an API that generates image with a random number to display it in a form to check that a real user is filling this form (not a flooder)
Does any body knows about such an API (may be a custom tag ) ?

Thank You !

Hello, It looks like you should implement it yourself.
I think these passages of code will help you:
The servlet code (in doGet method):

The getImage code - it generates BufferedImage,
which shows the fascia of percents passed in parameters
you can draw there digits, text, and other info,
which will be concerned with Session

For those coming in late, there is also a response in a (closed) duplicate thread here.
I agree. Here's the link:
