Secure registering...

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
Hi everybody,

I am developing a PHP project, where users must register and get
entered into a database - this is nothing new. It must be provided that
a malicious script cannot fill the database with garbage entries. I
have seen on some advanced pages how after sending register data a user
gets presented with a picture containing some text or number that
cannot be recognized by machine while easily by human. The user must
enter that number and send it back; only then gets he entered in the

This method seems to be rather secure, and I would like implement it in
my project.

Here is my question :

Where do these pictures come from? Are there any PHP-functions that
allow to generate them programmatically? Or any other way?

Can anybody give me an advice?
