A CAPTCHA is a program that protects websites against bots by generating and grading tests that humans can pass butcurrent computer programs cannot. For example, humans can read distorted text as the one shown below, but current computer programs can't:

The term CAPTCHA (for Completely Automated Public Turing Test To Tell Computers and Humans Apart) was coined in 2000 by Luis von Ahn, Manuel Blum,Nicholas Hopper and John Langford of Carnegie Mellon University.

A free, secure and accessible CAPTCHA implementation is available from the reCAPTCHA project. Easy to install plugins and controls are available for WordPress, MediaWiki, PHP, ASP.NET, Perl, Python, Java, and many otherenvironments. reCAPTCHA also comes with an audio test to ensure that blind users can freely navigate your site. reCAPTCHA is our officially recommended CAPTCHA implementation.

• reCAPTCHA. Stop spam and help digitize books at the same time! The words shown come directly from old books that are being digitized.

• SQUIGL-PIX. Our newest CAPTCHA!

• ESP-PIX. A CAPTCHA script that's close to our hearts. Instead of typing letters, you authenticate yourself as a humanby recognizing what object is common in a set of images. This was the first example of a CAPTCHA based on image recognition.

CAPTCHAs have several applications for practical security, including (but not limited to):

• Preventing Comment Spam in Blogs. Most bloggers are familiar with programs that submit bogus comments, usually for the purpose ofraising search engine ranks of some website (e.g., 'buy penny stocks here'). Microsoft office for mac os sierra 10.12 6. This is called comment spam. By using a CAPTCHA, only humans can entercomments on a blog. There is no need to make users sign up before they enter a comment, and no legitimate comments are ever lost!

• Protecting Website Registration. Several companies (Yahoo!, Microsoft, etc.) offer free email services. Up until a few years ago, most of these services suffered from a specific type of attack: 'bots' that would sign up forthousands of email accounts every minute. The solution to this problem was to use CAPTCHAs to ensure that only humansobtain free accounts. In general, free services should be protected with a CAPTCHA in order to prevent abuse byautomated scripts.

• Protecting Email Addresses From Scrapers. Spammers crawl the Web in search of email addresses posted in clear text. CAPTCHAs provide an effective mechanism to hide your email address from Web scrapers. The idea is to require users to solve a CAPTCHA before showing your email address. A free and secure implementation that uses CAPTCHAs to obfuscate an email address can be found at reCAPTCHA MailHide.

• Online Polls. In November 1999, http://www.slashdot.org released an online poll asking which wasthe best graduate school in computer science (a dangerous question to ask over the web!). As is the case with mostonline polls, IP addresses of voters were recorded in order to prevent single users from voting more than once. However, students at Carnegie Mellon found a way to stuff the ballots using programs that voted for CMU thousands oftimes. CMU's score started growing rapidly. The next day, students at MIT wrote their own program and the poll becamea contest between voting 'bots.' MIT finished with 21,156 votes, Carnegie Mellon with 21,032 and every other schoolwith less than 1,000. Can the result of any online poll be trusted? Not unless the poll ensures that only humans canvote.

• Preventing Dictionary Attacks. CAPTCHAs can also be used to prevent dictionary attacks in passwordsystems. The idea is simple: prevent a computer from being able to iterate through the entire space of passwords byrequiring it to solve a CAPTCHA after a certain number of unsuccessful logins. This is better than the classic approach oflocking an account after a sequence of unsuccessful logins, since doing so allows an attacker to lock accounts at will.

• Search Engine Bots. It is sometimes desirable to keep webpages unindexed to prevent others from findingthem easily. There is an html tag to prevent search engine bots from reading web pages. The tag, however, doesn'tguarantee that bots won't read a web page; it only serves to say 'no bots, please.' Search engine bots, since theyusually belong to large companies, respect web pages that don't want to allow them in. However, in order to trulyguarantee that bots won't enter a web site, CAPTCHAs are needed.

• Worms and Spam. CAPTCHAs also offer a plausible solution against email worms and spam: 'I willonly accept an email if I know there is a human behind the other computer.' A few companies are already marketing this idea.

If your website needs protection from abuse, it is recommended that you use a CAPTCHA. There are many CAPTCHA implementations, some better thanothers. The following guidelines are strongly recommended for any CAPTCHA code:

• Accessibility. CAPTCHAs must be accessible. CAPTCHAs based solely on reading text — or othervisual-perception tasks — prevent visually impaired users from accessing the protected resource. Such CAPTCHAsmay make a site incompatible with Section 508 in the United States. Any implementation of a CAPTCHA should allow blindusers to get around the barrier, for example, by permitting users to opt for an audio or sound CAPTCHA.

• Image Security. CAPTCHA images of text should be distorted randomly before being presented to the user. Manyimplementations of CAPTCHAs use undistorted text, or text with only minor distortions. These implementations arevulnerable to simple automated attacks.

• Script Security. Building a secure CAPTCHA code is not easy. In addition to making the images unreadable bycomputers, the system should ensure that there are no easy ways around it at the script level. Common examples ofinsecurities in this respect include: (1) Systems that pass the answer to the CAPTCHA in plain text as part of the webform. (2) Systems where a solution to the same CAPTCHA can be used multiple times (this makes the CAPTCHA vulnerable toso-called 'replay attacks'). Most CAPTCHA scripts found freely on the Web are vulnerable to these types of attacks.

• Security Even After Wide-Spread Adoption. There are various 'CAPTCHAs' that would be insecure if asignificant number of sites started using them. An example of such a puzzle is asking text-based questions, such as amathematical question ('what is 1+1'). Since a parser could easily be written that would allow bots to bypass thistest, such 'CAPTCHAs' rely on the fact that few sites use them, and thus that a bot author has no incentive toprogram their bot to solve that challenge. True CAPTCHAs should be secure even after a significant number of websitesadopt them.

• Should I Make My Own CAPTCHA? In general, making your own CAPTCHA script (e.g., using PHP, Perl or .Net) is a bad idea, as there are many failure modes. We recommend that you use a well-tested implementation such as reCAPTCHA.

It is sometimes rumored that spammers are using pornographic sites to solve CAPTCHAs: the CAPTCHA images are sent to a porn site, and the porn site users are askedto solve the CAPTCHA before being able to see a pornographic image. This is not a security concern for CAPTCHAs. While it might be the case that some spammers use pornsites to attack CAPTCHAs, the amount of damage this can inflict is tiny (so tiny that we haven't even noticed a dent!). Free 3d picture converter. Whereas it is trivial to write a bot that abuses an unprotected site millions of times a day, redirecting CAPTCHAs to be solved by humans viewingpornography would only allow spammers to abuse systems a few thousand times per day. The economics of this attack just don't add up: every time a porn site showsa CAPTCHA before a porn image, they risk losing a customer to another site that doesn't do this.

CAPTCHA tests are based on open problems in artificial intelligence (AI): decoding images of distorted text, for instance, is well beyond the capabilities of modern computers. Therefore, CAPTCHAs also offer well-defined challenges for the AI community, and induce securityresearchers, as well as otherwise malicious programmers, to work on advancing the field of AI. CAPTCHAs are thus a win-win situation: either a CAPTCHA is notbroken and there is a way to differentiate humans from computers, or the CAPTCHA is broken and an AI problem is solved.
