In fairness, we can say that captcha is an excellent way to protect any resource on the Internet from spammers, bots and other types of robot programs. Captcha is a randomly generated set of distorted (twisted, crossed out, etc.) characters of different colors and case, which only a person can recognize. It happens that the authors of captcha are so sophisticated that it becomes extremely difficult for the user to read it. An annoying test of humanity pops up here and there, annoying and taking time to parse sometimes almost hieroglyphic characters. Very often users want to disable captcha, but don't know how to do it.

But there is another side that justifies the existence of this protection mechanism. Automatic programs clutter up resources with ads, flood, spam forums and annoy other unnecessary, and sometimes harmful, garbage. It is worth noting that today captcha is a very simple and at the same time effective way to protect your site from such automatic programs.

However, the excessive zeal of site creators in the general application of captcha is very annoying for users. For some reason, the owners of Internet resources believe that this is not only a way to protect the site, but the squeak of modern fashion on the Internet, and they follow it with enviable persistence.

It does not take a genius to figure out that along with the development of resource protection, ways to bypass them and hack, that is, fraudulent methods. So if you are tired of constantly entering these distorted codes, then you can get rid of them without any problems and very quickly. To do this, you need to learn how to use just a couple of ways to disable captcha.

What are the types of captchas

In addition to the fact that a typical captcha is the input of distorted numbers, there are other types of this computer test.

These include:

• a combination in the code of letters and numbers of various fonts and registers, both Russian and English;
• arithmetic operation, most often elementary, but sometimes quite complex. Usually, complex captchas are placed on serious resources, in which bots are completely limited, and not a single spam will leak into such a system. But users complain that solving such an algebraic captcha requires knowledge of mathematical analysis;
• Pictures. Everything is simple here: a picture appears in front of you in the wrong location, by pressing the button, you put it in the correct position. Another option is to select related images by clicking on them with the mouse.

It should also be noted that the more complex the captcha, the better the site or other resource is protected. Do not forget that today you can prescribe, that is, create a captcha, on your own. It is not difficult, the main thing is to follow the correct, step-by-step and precise instructions, in which everything is explained and shown in detail. In order not to bother with self-writing captcha for your site, you can easily order such a service for a small fee. But sometimes the problem is not writing or buying reliable protection for the site, but rather getting rid of it.

You can disable captcha in several ways, which ones, we will now consider.

Getting rid of captcha

Sometimes the anti-spam mechanism can do a bad job, for example, make it difficult for real users to register on the site. It is especially disappointing when these visitors are attracted and very long-awaited customers. There were cases when the captcha settings were lost on the site and instead of the “Easy” level, “Difficult” was automatically selected. People, unable to decipher the security code, simply left the site.

In order not to nightmare users and, most importantly, not to be nervous yourself when, with every action on the Internet, you need to prove to the system that you are not a robot, you need to know the methods of getting rid of captchas.

So, let's take a closer look at how to remove captcha through the site's admin panel:

1. First you need to go to the editor of the resource itself.
2. After that, in the column, which is located on the right, select the function called "Settings".
3. Now in the settings we will need to select "comments and messages". Here, to the question “Use word verification?”, You must give a negative answer, click on the button with the answer “no”. In this case, a positive answer is set by the system by default.

The reason for the appearance of spam and what to do so that the captcha does not annoy ordinary users

It is the feedback forms that are most often spammed, since the purpose of this attack is to send an advertising type message to the site owner. Spam is poured in bags directly to the addressee, sometimes even bypassing the captcha by guessing. Extremely intrusive and spiteful advertisers do not disdain to work on weekends: by Monday they can put several hundred letters into the mailbox.

The negative consequences of this can be not only the loss of time for sorting mail. In the process of separating the grains from the husk, you can inadvertently remove an important letter. Worst of all - this is a real chance to get blacklisted by the hosting provider, on the site of which your mailbox is located.

It should be noted that the forms are besieged not just by spammers, but also by doormen who do not distinguish feedback form from the form of messages or comments. So everything gets spammed. Disabling captcha means getting rid of protection, so before doing this, think about whether you need it.

To protect your site from spam attacks, but at the same time not to annoy ordinary users with constant captchas, you can use the so-called invisible field. To do this, you need to create the simplest input field, but at the same time, hide it through the CSS system. Then a regular user simply won’t have to fill it out, because this code will be invisible to his eye, but a spam bot will not be able to pass such a check.

How to get rid of captcha

First method: dynamic IP address

There is a simple and effective way to get rid of captcha - order a dynamic IP address in a virtual private network. Usually this service is paid, and its cost depends on the rates of the VPN provider. But it will help protect the user from surveillance and ensure complete anonymity - no one will know what Internet resources you visit. And the site will not understand at all who visited it. Your IP address will change every time you connect to the Internet from any device - be it a laptop, PC or smartphone.

This method is guaranteed to save you from annoying captcha - which means that you will not need to sigh irritably every time the program decides to check you for humanity.

The second way: special services

You can use the services special services, which will enter the captcha for you automatically. The most famous of them are anti-captcha and rucaptcha. This is a paid service, but it is inexpensive - the system will charge 40-50 rubles for solving 1000 pictures (according to Rucaptcha tariffs).

This service has real people. earn money by entering captcha for reward. And you, having paid for their services, will receive a special key that will help you not bother with captcha.

Third way: dig into the settings

First of all, you need to find out why captcha appears so often? It makes sense for Google Chrome users to check extensions. For example, if you disable the ad-blocking AdBlock extension or the RDS bar plugin, then most likely the captcha will no longer appear.

Captcha (CAPTCHA), requiring to prove that "I'm not a robot", appears on an increasing number of sites and services, and annoys users. There are several reasons why sites mistake visitors for bots and require the introduction of verification characters. Is it possible to get rid of the repetitive check, what needs to be changed in the browser settings and the Vkontakte page, how to bypass the captcha using VPN services?

What is a captcha?

CAPTCHA is Turing's automated public test. It allows you to identify a bot among site visitors. The mechanism for protecting web services from spam was developed in 2000 by a team at Carnegie Mellon University. The idea of ​​the test is that the proposed task is easily performed by humans, but inaccessible to machines.

Most often, users need to enter characters from the picture. They are depicted with noise, or translucent, so that the machine could not recognize them. Initially, the system worked well, reduced the load on the sites, saved them from fake comments.

Seven years after the creation of the Turing test, a modification appeared - reCAPTCHA. People were asked to recognize words in scanned editions of The New York Times. Spam protection also helped to digitize the publication.

But computers became more powerful and were able to recognize characters. Therefore, other options appeared: search for cats, road signs in pictures, or a check mark next to the phrase “I am not a robot.”

A useful test for site administration began to annoy users. Sometimes you have to enter captcha several times to see some page. Captcha in VKontakte becomes a separate problem.

There are several reasons why the user has to constantly prove that he is not a robot. Even if a person does not spam, but simply leaves comments or communicates on social networks, he may be harassed by typing characters.

Suspicious traffic from the computer. Browser extensions or viruses on a user's device can become part of a bot network. For this, reCAPTCHA blocks his IP address.

Bad Company. Providers allocate one real IP for a group of subscribers. Therefore, if one of them is a bot, it is blocked, and the whole group is blacklisted.

Turn off JavaScript on your smartphone. The reCAPTCHA mechanism is the JavaScript code on the site. Codes are used not only by services, but also by scammers, so JavaScript is disabled in smartphones for security in browsers. This causes reCAPTCHA to malfunction.

How to get rid of captcha

Change settings

Google Chrome users can get rid of annoying security by disabling a number of extensions. An ad-blocking extension like AdBlock or the RDS Bar plugin often results in captchas.

Another option for computers is to reconnect to the internet. After rebooting the modem or router, the user can get a new external address and get rid of annoying checks.

iPhone owners can open the "Add-ons" tab in the Safari settings section and enable JavaScript. Android users in Chrome, you need to click on the three-dot menu, go to "Settings", open "Site Settings" and also enable JavaScript. Another option for mobiles is to briefly turn on airplane mode, after which the smartphone will be re-registered on the network and will be able to get a clean IP.

You can get rid of VKontakte captcha in a few minutes. In the page settings, go to the "Security" section, click on "Show activity history". A pop-up window will show the history of visiting the site and the IP from which the login was made.

If there is an address in the list that differs from the user's address, you need to click "End all sessions". And then change the password. In addition, captcha appears less frequently if the page is linked to a phone number.

Special Services

If you are too lazy to enter captcha even occasionally, other users will do it for a fee. On specialized web services, they will take about 40 rubles for solving a thousand pictures. The user will receive a special key that allows him to forget about the annoying test.

Dynamic IP

If the witchcraft with the settings did not help, you will have to use VPN services. Large companies provide this service for a fee. But there are also free services with a good interface and easy to use. For example, the CyberGhost VPN program ( free download >>).

The service works with all popular browsers and is perfectly secure thanks to the OpenVPN protocol with 256-bit AES encryption. You can only run it for free on one device. The user will have access to 37 servers in 12 countries, work without interruption for about three hours, after which he must reconnect and continue working.

HOW TO DISABLE "I AM NOT A ROBOT" IN THE BROWSER WINDOW

Often, many computer users are faced with a situation where, when trying to find some information on the Internet in a browser window, instead of search results, they see a picture offering to confirm that they are not a robot. And for further surfing the Internet, unfortunate users have to type captcha or stare at blurry pictures, in general, waste time to prove that they are not robots, but just people who wanted to go online. In this article, I propose to understand why this happens and how to deal with this problem.

For those who are more accustomed to watching and listening than reading, this article is posted on YouTube at this address.

Why is this happening?

First, let's figure out why this happens. First, this problem is due to the fact that some search engines have taken the responsibility to control the "behavior" of users on the Internet. This is usually done to prevent the use of specialized programs that imitate the actions of ordinary Internet users visiting various sites.

Secondly, such a situation can arise when Internet users excessively use the services of various anonymizers, VPN clients, and also use other tricks to hide information about the Internet user or replace it with another one (real or virtual).

In what browsers does it happen?

This can happen in any browser that uses Google or Yandex search engines. Moreover, in this matter, the search engine "Google" shows great "maliciousness". Figure 1 shows the appearance of "distrust" to the user from the search engine "Google". Figure 2 shows a similar situation with the Yandex search engine.

Figure 2 (see 1 Figure 2) shows an example of a captcha for identifying an Internet user in the Yandex search engine. Figure 3 shows an example of identification in the Google search engine.

To deal with this situation, different users use different methods. Someone stubbornly peers into the proposed text or picture, types this text or clicks on the “correct” images, someone fights this trouble with the help of specialized programs, and someone just spits on this situation and stops trying to find an answer on the Internet to his question.

But the solution to this problem is extremely simple (at least at the moment).

Ways to get around the "I'm not a robot" problem when searching for information on the Internet

First, reduce the use of various anonymizers, VPN clients, etc. to the necessary minimum.

Secondly, as noted above, this problem does not depend on the browser used, but only on the search engine. From this it follows - just go to another search engine. At the moment, the most reliable and not biased in this matter are the search engines "DucDucGo", "Yahoo" and "Bing". There are other search engines that, in a rush to block search spam (manual and machine), have not yet tried to mock Internet users who, for some reason, "too hard" disguise themselves. If you do not want to change the settings of search engines and browsers on your computer, once chosen by you, simply set the links to the above search engines to the bookmarks bar of your favorite browsers. And when "Google" or "Yandex" require you to prove that you are not a robot, just open any of these links and re-enter your search query in the search bar.

I do not give direct links to the indicated search engines, because they (links) can change from time to time, and keeping track of the changes is quite difficult, especially remembering in which article and in which place this link was used. You can always find these links on the Internet.

Thirdly, if you still have an urgent need to use the Google or Yandex search engines while searching the Internet (for example, you were blocked on some site), then when searching, use not a search phrase, but a specific URL. Google, unlike Yandex, loves this very much.

Well, in conclusion, as I said above and in the article "", you should not excessively, unnecessarily use the services of anonymizers, VPN clients, etc. and too often hiding on the internet. First, it is easy to calculate. Secondly, despite the fact that the distributors of "anonymous surfing" services shout in unison that their services are absolutely safe, this is far from being the case. Who can be sure that when you install a VPN client on your computer, you do not install some kind of Trojan along with it? Who can be 100% sure that anonymizer servers do not keep a log of your actions through their server? And in general, how did you check the reliability of companies that provide anonymous surfing?

There are other ways to turn off the "I'm not a robot" identification system. I suggested one of them and, in my opinion, the simplest. I do not know how long it will work, because. Recently, most search engines have become too fond of "keeping a finger on the pulse" (more precisely, on the throat) of their users and forcing them to constantly register and give them their confidential information.

Itsenko Alexander Ivanovich

The company claims that its reCAPTCHA system can tell human from machine without any complicated tasks or checks.

What is reCAPTCHA?

reCAPTCHA is the leading CAPTCHA service on the web. Probably, each of you has seen the so-called "captcha" many times when registering on a particular site. To automatically identify people from spam bots, you are asked to enter words or numbers from the image in the required field, select several images containing the desired objects, or simply check the box. But now the captcha will appear less frequently, because Google did her hidden. However, it won't disappear.

How does it work?

The old reCAPTCHA was pretty simple - just a simple "I'm not a robot" checkbox. The new version has become even simpler, there are no tasks or checkboxes in it. It works invisibly and separates bots from people. Google did not go into details about how the system works.

The new version of the system combines machine learning and an advanced risk analysis tool that adapts to new threats.

More information about the system will likely help bot creators come up with a way around it, so don't expect details anytime soon.

Google bought reCAPTCHA in 2009. Some CAPTCHA systems ask users random questions, but the old version of reCAPTCHA was actually used to solve problems that Google needed to solve. Google digitizes millions of books, but sometimes the OCR software fails to recognize a word and it is submitted to reCAPTCHA. If you've ever seen a reCAPTCHA that looks like a string of numbers, it's from Street View cars racing through the streets and identifying house numbers. If the software could not determine the house number, this photo was converted into a captcha for human recognition. Sets of images with requests like "Choose all cats" were used to train computer image recognition algorithms.

When sites switch to invisible captcha, most users won't see it at all. But if your system is marked as "suspicious", you will be asked to solve one of the usual tasks.

Experts have finally improved the captcha, saving the user from having to enter words and perform other incomprehensible actions. From now on, bot recognition technology is able to independently determine whether a person is in front of it or not. figured out how the war with the machines began and who wins in it.

New Hope

Captcha (CAPTCHA - Completely Automated Public Turing test to tell Computers and Humans Apart) is an automated public Turing test aimed at identifying computers among website visitors. This protection mechanism should protect sites from spam, automatic registrations, cheating and other hard-hitting things that bots usually do.

The classic captcha is the need to decipher a heavily distorted text that is difficult to recognize by software algorithms. Google's no-CAPTCHA technology deviates from the standard concept of Turing's automated test and evaluates the user's behavior on the web, and not his ability to guess words.

The user needs to perform the simplest action - tick the statement "I'm not a robot." At this point, a special script evaluates indirect parameters that indicate a possible bot: information about the time spent on the page, IP address, and so on. If No CAPTCHA has doubts that the user is a human, then it will offer to perform a simple task, such as searching for a specific object in pictures or entering a standard captcha.

Compared to the classical system, even the current implementation of No CAPTCHA does not burden users much. And the advanced technology does not even require ticking. When checking, a small window will open on the screen, in which a checkmark is automatically checked, informing the user that he is still not a robot. If the system is not sure about this, it will run the same verification mechanism as before.

Talking about No CAPTCHA, developers are limited to links to machine learning and advanced risk analysis that adapts to new threats. And they can be understood: without knowing the principle of the system, hackers will not be able to bypass it.

Birth of a legend

The original version of captcha was developed in 2000 by specialists from the American Carnegie Mellon University. The team, led by Luis von Ahn, set out to create a defense that is resistant to recognition and guessing. This means that the captcha must be unsolvable for text recognition systems and other algorithms, and also it cannot be guessed in a small number of attempts (less than 1000). But for a person, it does not present any difficulty.

One of the first and easiest ways to bypass protection is to contact a regular user. Spammers simply paid, and ridiculous money - a cent per picture, but in poor countries this is a lot. But in general, the system was effective, and the developers were already puzzled by a completely different problem.

Captcha creators understood that millions of users spend a lot of time solving ciphertext puzzles, and it would be nice to channel these resources into a useful direction. So in 2007, reCAPTCHA appeared, combining, as they say, pleasant with useful. Its key feature is that the system not only protects websites from bots, but also performs the function of decrypting archived documents.

ReCAPTCHA prompts the user to enter not one, but two words, which is quite rare in other systems. The secret is that one word is already known to the system, and it will be checked against it, and the second is taken from a scanned document that cannot be decrypted by the algorithm. Thus, when passing the test, the user helps to decipher the real text from the old document. Of course, no one will pay him for this, and few knew about such a trick.

When archive numbers were decrypted using reCAPTCHA, the authors of this system were noticed by Google. As a result, the “corporation of kindness” bought the service (in 2009) and took up the decoding of old books, and then the recognition of fragments of images from Google Street View. Thanks to the service, approximately 100 million words were digitized per day, which yielded more than two million books a year.

Besides reCAPTCHA, there are many other options. Craftsmen from all over the world create defense systems using logical and mathematical problems, integrate simple games and develop more and more advanced options. But the classic captcha with text remains one of the most balanced systems, although it no longer saves from bots.

Useless defense

One of the main problems of any captcha is its execution. Bots are not a problem for users, but for site administrators. It is incorrect to shift its solution to ordinary people, especially since when entering the next captcha, users experience only irritation.

With the development of algorithms and artificial intelligence, many protection mechanisms have become almost useless. Such a fate befell audio and video captcha, as well as many protection options with logical questions and pictures. In 2014, Google itself demonstrated an algorithm capable of recognizing and cracking even the most complex reCAPTCHA images with a 99.8 percent probability. By the way, this indicator is even higher than that of a person.

There are many complaints about reCAPTCHA itself. First of all, the need to enter two words increases the time to complete the task. We should not forget that the user helps to decipher the books, thereby doing work for Google, and no one pays him for this work. Therefore, the step of the search giant to change the usual captcha to something smarter and more inconspicuous looks right. The only question that remains is how smart the system will work and whether it will definitely make life easier for ordinary users.
