ReCAPTCHA - the simplest captcha I'm not a robot from Google. Problems with captcha - I'm not a robot How it works I'm not a robot

The inscription "I am not a robot" on the screen annoys many users. There are several reasons why websites mistake visitors for robots. And you can get rid of captcha (CAPTCHA) by correcting your browser settings, pages on social networks or 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.

Why was mistaken for a robot

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.

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.

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?

Dynamic IP

Quite often, users began to contact me with the same question that when searching, the Google search engine constantly asks to enter the code from the image. And for some, when entering Google, it immediately asks you to enter a captcha, without even opening the search line itself.

And, so that there are no questions, I will try to explain why this happens and how you can try to solve this trouble.

Why does Google keep asking for a code?

There are actually not so many reasons, or rather two.

1. The most popular reason is that you have a dynamic ip address (usually from mobile operators), which is used by many users. Not all users are "equally useful".

If some users access the network for work, leisure or communication, then others can spam, parse search results, run various programs (bots) that automatically send many requests to the search engine or other sites, which ultimately leads to that the ip address gets into different blacklists and spam databases.

By the way, not all Internet providers are in a hurry to “pull out” their ip from spam lists.

And some do not get ip on purpose, so that they spam less.

2. An equally popular reason is viruses on your computer. They downloaded a browser extension or a program, and it contained a “surprise” in the form of a virus.

BUT, do not rush to panic, usually viruses want money, and do not force you to enter a code when entering a search engine 🙂

Yes, I almost forgot that in addition to entering the code and phone, it happens that Google simply writes:

"We have registered suspicious traffic originating from your network"

and there is no captcha, but just a white page and the search does not open at all. In this case, it's the full ip bases.

What to do if Google requires you to enter a captcha?

The steps are really simple:

1. If your ip is dynamic, then it changes every time you connect to the Internet.
You just need to reboot the modem, router and reconnect to the network.
It is advisable to restart the computer too, although it is not necessary.

2. Try to register the public DNS of Google itself, in many cases this helps.

How to write:

go to network and sharing management
click on Change adapter settings

In the window you will see all your connections.

Highlight your connection, right-click and select properties.

At the very bottom of the list there will be an item Internet Protocol version 4, select and click properties.

Set the parameter to use the following dns server addresses and write as shown in the screenshot:

we prefer dns-server we enter
8.8.8.8
alternate DNS server
8.8.4.4

Click OK and reboot the router for the changes to take effect.

As a rule, this helps and Google no longer asks you to enter captcha when searching.

If for some reason you want to return everything back, in the same window, check the Obtain DNS server address automatically option and click ok. (this will reset everything to its original state)

You can also write to change the provider that has "gray" ip addresses, but this option is not suitable, since almost all mobile operators have problems with captchas.

Well, not everyone in the cities has the opportunity to choose a provider.

But, if the method above did not suit you and google constantly asks you to enter captcha, there is one more additional method to everything described above, which should save you from the appearance of google captcha.

1. Create a mailbox on gmail.com (if you don't already have one).

2. In the Google Chrome browser, go to the settings and log in with your mail that you created.

Once you do this, google captcha won't show up as often.

If you use a browser other than Google Chrome, but use Google search, there is only one solution, open gmail mail in one tab and be authorized in it.

And lastly, check your computer for viruses and any kind of "bad" that can independently conduct some kind of activity on your computer, just in case 🙂

Hello, dear readers of the blog site. Literally a bit of time I want to devote a relatively new captcha from Google (it was announced about a year ago), which replaced the old and confused one. Previously, probably few bloggers in their right mind could put the brainchild of Google on their website or blog - it was very dreary to solve the letter puzzles offered there. All the convenience of commenting was lost.

Actually, at that distant time, I still used a perfectly working . To pass it, you just had to put check the box "I'm not a robot" and all (of all possible). If the checkbox was not checked, then the message fell into the basket in the WordPress admin panel, or when the basket was disabled (as in my case), it was simply not added to the database. An ideal option, in my opinion, because it did not create any particular inconvenience for the commentator.

Then this plugin stopped working, and I used it with success for about six months, but this method also stopped working after updating WordPress to version 4.4. During this time, I tried a couple of plugins that filtered out spam based on the analysis of the addressee and content (Antispam Bee and CleanTalk). The first confused quite a lot (spam is not spam, but non-spam is spam), and the second, contrary to expectations, did not reduce, but increased the load on the server (and it was also paid).

In general, I decided to return to the proven method - installation of the simplest of the existing captchas. DCaptcha no longer works, but the giant Google has seriously simplified its initially monstrous reCAPTCHA and reduced the entire check to the very “I'm not a robot” checkbox. Unfortunately, I'm too dumb to figure out how to tie this thing to the site without a plugin (although I tried it), so I had to use the services of the No CAPTCHA reCAPTCHA plugin. But first things first.

Spam mitigation techniques and why reCAPTCHA?

As you probably know spam can be manual and automatic. You can protect yourself from the first only by turning on the mandatory moderation of all incoming messages before publishing them on the blog - then for sure no “radish” will break through.

But manual spam is usually a tiny trickle compared to the full-flowing river of autospam. The latter can be generated, for example, by Khrumer in simply fantastic volumes. Personally, it’s not even the fact that several hundred spam comments come to my WordPress admin panel per day that annoys me more, but the fact that they are monstrously long and you get tired of scrolling to the “Delete” button. In general, this problem is real and all the more relevant, the more popular your blog is.

It makes no sense to deal with manual spam (due to the doom of this struggle and because of its insignificant volume), but something needs to be done about autospam. It's like there is two main approaches:

Filter comments already added to the WordPress database for spam / non-spam and shove them into the appropriate folders. Unfortunately, plugins that work on this principle give out a lot of marriage and just clearing the Spam folder without viewing its contents will not work if you do not want to lose dozens of really valuable comments sent by active readers of your blog.
Attach an additional check to the form for adding a comment on who exactly leaves this message - a live person or a bot. The task of identifying this difference is called the Turing test and is solved in the vast majority of cases using the so-called captcha (derived from CAPTCHA, which is an abbreviation for a set of clever words). The main problem with this method of fighting spam is that you strain the commenters by solving the “rebus” (captcha), which can discourage them from even any desire to continue trying to leave a message.

However, captchas, as already mentioned, are quite simple. Google has taken a major step in this direction and now his new reCAPTCHA just an example of simplicity and elegance for the vast majority of users who come to your site (although a small number of them may still be asked to enter characters from the picture if the algorithm has doubts about its humanity).

This is how Google's reCaptcha will look like for 99.9% of your website visitors:

Well, and like this, in the event of a force majeure (if the algorithm, after conducting a dozen tests for humanity, is still confused):

The strength of this protection can be judged by the fact that on services for recognizing captcha (or) they take twice as much money for recaptcha. A very telling figure.

Well, as if the choice is made - it is necessary to implement it.

Registering a site in reCAPTCHA and installing it on your blog

Registration is simply an indication of the name and domain name of your site, where you plan to use this very captcha:

After that, you will be taken to the admin panel of the reCAPTCHA service for your site (it probably makes sense to add it to your browser bookmarks). Over time, statistics on the operation of this captcha will be displayed there, but for now, the most important thing that we can learn from here is just the same keys, without which "I'm not a robot" will not work:

Below are the installation instructions. Everything is clear in the "Client-side integration" area, but simply installing the above code in the indicated places is not enough. Captcha will be displayed, but spam will not be filtered. In the “Server-side integration” area, I don’t understand anything at all. I'm dumb for this.

Therefore, the decision was made use plugin to integrate reCAPTCHA in WordPress, fortunately, there are a lot of options for such plugins (read). True, three of them did not work for me (the captcha did not appear in the comments area). After several unsuccessful attempts, I had to turn to smart people for a solution, where I was noticed and subsequently successfully installed a plug-in with an intricate name (such as non-oily oil) -.

Setting up and working the No CAPTCHA reCAPTCHA plugin in WordPress

Well, actually, go to the WordPress admin panel, select "Plugins" - "Add New" from the left menu, enter No CAPTCHA reCAPTCHA in the search box and install. Do not forget to activate it, and then go to its settings in the usual way (at the bottom of the left menu you will find a new item "No CAPTCHA reCAPTCHA").

Actually, here, of all the settings, the most important is, again, entering the keys obtained just above on the reCAPTCHA website:

After saving these changes, the plugin immediately stands up for your comments from spammers.

And not just comments. In the settings you can protect the WordPress admin login form with this captcha:

Even in the settings, you can replace the light color scheme of the recaptcha with a dark one, and either let the captcha guess the user's language itself, or set it forcibly.

Actually, everything. I haven't forced a cache reset in WordPress yet (I've only updated articles that Hrumer is traditionally not indifferent to), so reCAPTCHA is not displayed on all pages. So far, no complaints have been noticed in the work.

Good luck to you! See you soon on the blog pages site
