    Captcha can be a great help in downsizing or diminishing form spamming.form spamming is when bots go around the web, find forms and either hijack them-meaning they send thousands of spam emails through that form or - in the least - send at least one e-mail through that form.
    Or, they fill in the form and sign up for hundred free e-mail accounts, or order hundreds of services and even products.

    Is a tool against hackers who intend to steal some data. You imagine when a hacker uses the account registration tool on a web page, the overload leads to the web and the information in it is also lost.

    Captcha are basically used for avoiding the spam account registration, hacking the account details and safe our-self from robots which are automated to just fill the registration or contact form to spared the spams around the network.

    There are various types of captcha. Without verifying the captcha, you can not proceed. Those captchas provide the layer of security for your accounts.

    The word CAPTCHA was first used by laptop or computer researchers at Carnegie Mellon School in 2000. CAPTCHA is actually an abbreviation that appears for Absolutely Computerized Community Turing analyze to tell Pcs and People Apart.
