So are you ready to pay for the captcha?

There are free captcha's that you can get but as far as I've experienced, they don't stop a great deal of bots because they're pretty simple, for example a few digits perfectly lined up.

In a CAPTCHA test (an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart," also sometimes spelled in lowercase), an image of letters is dynamically generated. The letters, because they're part of an image and not text (e.g. text that you could cut and paste), are difficult for a spambot or other computer program to read. Yet, a person has little trouble reading the letters in a captcha image.

Using a captcha test on a website is a great way to ensure, for instance, that a person and not a spambot is filling out a web form. Also, a captcha can make it difficult for a person to continuously resubmit form information and overwhelm the form's purpose.

I hope while registering on this forum you might have came across with the Image Verification "Captcha" :), for more detail about it you can also refer this wikipedia (http://en.wikipedia.org/wiki/Captcha)article. You can get the captcha for your website from here (http://www.captcha.net/).

A CAPTCHA or Captcha (IPA: /ˈkæptʃə/) is a type of challenge-response test used in computing to ensure that the response is not generated by a computer. The process usually involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. Thus, it is sometimes described as a reverse Turing test, because it is administered by a machine and targeted to a human, in contrast to the standard Turing test that is typically administered by a human and targeted to a machine. A common type of CAPTCHA requires that the user type letters or digits from a distorted image that appears on the screen

Captcha is mainly used for thwarting the attempts of the spammers. Here an image is being placed which one has to write on a given box before submitting anything or before proceeding further.

Usually, how does it cost if you subscribe for a captcha service? Many websites are really doing applying this to avoid spams. At first, I was really wondering what is it all about and what it is for but eventually, I got it! And it is very important for websites that require registration.

The new and improved Recaptcha is like captcha, but accessible to the blind and involves its users in a public effort to digitze old books and periodicals. Learn more here.

Hello Friends....

CAPTCHA typically involves a computer which 'serves up' a puzzle (this usually involves number and/or letter combinations) that a user has to input into a designated box in order to proceed with whatever process the CAPTCHA is guarding

Captcha is an image verification module that is used to verify whether or not someone is a real person. If you have signed up for an email address before, then you have probably seen a Captcha box before. It is a strange looking image with oddly shaped characters in it, also it is very difficult for a program to decipher the image content. The Captcha box prompts the user to enter in the information sen in the image to verify that the user is indeed a genuine human being.

If you work at a website design company (as your signature would suggest) it is hard to believe you wouldn't know what captcha was, but...
If you look it up in the dictionary, it will say:
captcha -
1. pain in the rear.
2. a necessary evil.
It works to stop spammers (at least machines) but it can be very frustrating to us humans that don't see so well. :)

A CAPTCHA (Completely Automated Public Turing Test to tell Computers and Humans Apart) is a challenge-response system test designed to differentiate humans from automated programs. A CAPTCHA differentiates between human and bot by setting some task that is easy for most humans to perform but is more difficult and time-consuming for current bots to complete.

CAPTCHAs are often used to stop bots and other automated programs from using blogs (see splog) to affect search engine rankings, signing up for e-mail accounts to send out spam or take part in on-line polls.

A Captcha is a program that can generate and grade tests that humans can pass but current computer programs cannot pass.These were created in response to bots that automatically fill in Web forms as if they were individual users. Bots are used to overload opinion polls, steal passwords and, most popular, to register thousands of free e-mail accounts to be used for sending spam.

CAPTCHAs are used to prevent automated software from performing actions which degrade the quality of service of a given system, whether due to abuse or resource expenditure. CAPTCHAs can be deployed to protect systems vulnerable to e-mail spam, such as the webmail services of Gmail, Hotmail, and Yahoo! Mail.
CAPTCHAs are used to stop automated posting to blogs, forums and wikis, whether as a result of commercial promotion, or harassment and vandalism.

The CAPTCHA security image works by asking the website visitor to type in a code they see correctly. A human can do this, but an automated computer program cannot.

Captcha is used to know if the user is really a human and not just a programmed robot. It would display figures which contains letters and/or numbers in which the user would identify and the robots wouldn't. That way, spammers would be prevented to spam on your website.

When it comes to integrating that on your website, Google is you best friend! So, good luck!

It is automatically generating challenge that human can pass but not the computer. Humans can read distorted text which can't be read by computers. It is used for preventing comment spam and protecting website registrations, also preventing dictionary attacks and worms/spams.

CAPTCPA is mainly used to prevent automated software (bots) from performing actions on behalf of actual humans. For example while signing up for a new email account, you will come across a CAPTCHA at the end of the sign-up form so as to ensure that the form is filled out only by a legitimate human and not by any of the automated software or a computer bot. The main goal of CAPTCHA is to put forth a test which is simple and straight forward for any human to answer but for a computer, it is almost impossible to solve.

A CAPTCHA is a type of challenge-response test used in computing to determine that the user is not run by a computer. The process involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. A common type of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen.

CAPTCHA or Captcha (pronounced as cap-ch-uh) which stands for “Completely Automated Public Turing test to tell Computers and Humans Apart” is a type of challenge-response test to ensure that the response is only generated by humans and not by a computer. In simple words, CAPTCHA is the word verification test that you will come across the end of a sign-up form while signing up for Gmail or Yahoo account. The following image shows the typical samples of CAPTCHA.

Some people and companies put those on their websites to make sure that the person filling out a form is actually human, and not a "bot" that will just submit a bunch of garbage or spam or try to fish for email addresses and such. The reason it uses highly distorted letters and numbers is that we humans are WAY better at recognizing them, even when they're all bent out of shape, than machines are. Even if a spam bot had optical character recognition (OCR) software, it would still find it nearly impossible to figure out what all those twisty, colourful shapes were, preventing it from giving the right answer to the captcha test, and keeping them out of the form's results. Hope that clears it up!

By now all of us at one time or another have had to read a construed image and type the letters and numbers we saw into a textbox. This test is what is known as a CAPTCHA, and it prevents bots (programs created to spam websites among other objectives) from submitting a form on a website. The reason it prevents bots from submitting a form (and its agenda) is because bots can't decipher the text within an image, and thus it cannot fill out the correct response in the textbox. Although there are ways around CAPTCHAs for the most sophisticated bots, you can be relatively sure that a form submission is from a human in using this test.

Captcha is a method to lessen the spam or bots accessing your websites. One quick note to consider is that it is NOT an additional security. There are alot of systems and programs that bypass captcha. These are free and paid. You can either use a captcha from providers like recaptcha or create one from a script like javascript.

A CAPTCHA is a type of challenge-response test used in computing to determine that the user is not run by a computer. The process involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. A common type of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen.

CAPTCHA is a validation tool that requires a person to type in the text that they see in a graphic in order to submit a form. It is used to confirm that the form is coming from a real person and not something automated.

To check whether the captcha was successsful

Add the following PHP in your form processing page:

require_once('recaptchalib.php');
if ($_POST["recaptcha_response_field"]) {
$resp = recaptcha_check_answer ("private_API_key",
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);

if ($resp->is_valid) {
# they got the captcha right
echo "Do something here, such as setting a variable you can use later.";
} else {
# set the error code so that we can display it
$error = $resp->error;
}
}

Change private_API_key to the one you received when you signed up.
To display the captcha:

Add the following PHP in the page that will display the form:

require_once('recaptchalib.php');
echo recaptcha_get_html("public_API_key", $error);

Change public_API_key to the one you received when you signed up.

It's some sort of validation image that tries to avoid spammers or bots to tented get on your website, the most common is the captcha from google right now, but u can create your own image verification using php and a background image.

The nex methods that the website are implementing is that u have to fill the end of a word, that word is aleatory as well.

Thoose are security measures.

Short for completely automated public turing test to tell computers and humans apart, a technique used by a computer to tell if it is interacting with a human or another computer. Because computing is becoming pervasive, and computerized tasks and services are commonplace, the need for increased levels of security has led to the development of this way for computers to ensure that they are dealing with humans in situations where human interaction is essential to security.

The term CAPTCHA may sound strange at first but honestly we're all using it everyday of our lives. Many Captcha or challenge systems only allow people with perfect vision, perfect hearing, and people who can figure out a specific computer puzzle. It's main goal is to prevent automated actions, in various situations.
