| PHP Form Captcha is a powerful script that can
protect your form, comment area, guestbook or shopping
cart from automatic submissions, the tool
generates an image with distorted text which your
visitor is required to type into a text box, The idea is
to prevent spammers from using web bots to automatically
post form data in order to create email accounts (for
sending spam) or to submit feedback comments or
guestbook entries containing
spam messages. The text in the image is usually
distorted to prevent the use of OCR (optical character
reader) software to defeat the process. Using PHP Form
captcha you will be sure that the data entered in your
form came from your visitor's fingers not from any
computer software. Hotmail,
PayPal, Yahoo and a number of blog sites have employed
this technique. It is the right time to protect your own
web site with the very same technology ! |
