What is captcha? How to enter or remove captcha?

If you are more or less actively using the Internet in your daily work, you probably know about such an unpleasant thing, which is captcha. Sometimes it is so hampered in the work that people often just stop visiting those sites, the owners of which give it too much attention.

What it is?

By the way, and what is captcha? Imagine that you went to some popular file sharing service. To download the file in free mode, you will have to enter in a special field a certain set of symbols (often meaningless), which should be taken from the picture opposite.

The task is complicated by the fact that these characters are sometimes completely impossible to make out, as they are knowingly rendered unreadable.

What is it for?

Having dealt with what a captcha is, it would be nice to talk about its specific purpose. Why do you need to fence such a garden, making it harder to send comments or download files?

Yes, there were times when no one knew about the CAP. She appeared comparatively recently. It happened in the same period when in the open spaces of the Runet a lot of bots were bred, with the help of which enterprising citizens left advertisements in comments, downloaded files and created other disgraces.

Of course, many resources were followed closely by administrators, but in most blogging services the load on them turned out to be such that they banally stopped coping. That's when users found out about CAPTCHA! Acquaintance was quite unpleasant.

If to speak absolutely precisely, the technology itself was originally created in 2000. Initially, it was intended only to determine the "humanity" of your interlocutor on the Internet: then no program for captcha (for its recognition, more precisely) was simply not created.

What is its drawback?

If you carefully read the first part of the article, then most of the negative factors of using CAPTCHA can be guessed yourself. First, users mostly operate in a state of a rush. Simply put, when you see some interesting post in the same LJ, then you want to immediately comment on it.

That's just before you gets indigestible captcha, and most of the characters are so indistinct that it can take many days to solve them. Do you think the user will be engaged in such an ungrateful business?

Of course not! He just goes to another site. Thus, if you are trying to protect your resource from fans to leave spam in the comments, we advise you not to too hard.

If you are too keen on captcha, you will quickly lose many active users. No users - no money from advertising. In addition, most of the normal resources automatically recognizes spam in comments, so there is usually no point in additional protection.

Almost the same can be said about the sites for file sharing. Of course, you can understand their creators: by offering all and free to download information of interest, they will simply miss the profit.

But you can look at the same situation from the opposite side: if the site offers you the opportunity to receive a file for free, it will easily recruit a huge audience that will quickly pay for all costs by attracting advertisers. By the way, this is how the domestic iFolder works, whose creators can not complain about poverty precisely.

So, even from the point of view of making a profit, the very idea of the captcha does not look so attractive.

What to do?

And how to remove captcha, is it really possible to do this? Here the situation is rather ambiguous. The fact is that on many sites that use this type of protection against spam, it is not possible to read every time from the first time, not to mention any applications.

Simple options can be recognized with the help of a small utility Screenshot Reader, which is a part of the software package ABBYY FineReader. But it reads only the simplest forms of captcha, which can be easily recognized by any normal user. In addition, the process itself can not be automated, since for recognition it is necessary to manually select the range of interest.

Captcha input

If you have no particular choice, you will have to deal with this ungrateful work manually. What advice can I give? First, try to do it faster: many sites have a counter that resets the value if you can not enter it within a couple of minutes.

In addition, mistakes when writing characters often occur when JavaScript is disabled in your browser. Do not forget also about the need for Cookie, as they will help the site "learn" you, eliminating the constant passage of bored protection.

Finally, pay attention to what is written on the main page of the site. Typically, captcha for a site can be described in detail in an explanatory note or in a separate article. An excellent example is the file-sharing service Rapidshare, which in its time introduced a unique captcha.

Its symbols were easily distinguishable, no blur or polarization technologies were used that would make it difficult for the programs to recognize it. What was the secret?

And it consisted in the fact that on those letters and numbers that needed to be entered into the appropriate field, sat seals. How many at one time was said impartial words addressed to the creators of such a system! In the end, it was abandoned by the pressure of the user community.

Buy antidote

Another option is to contact a normal programmer (or a group, which is even better) in order to make a utility for recognizing the CAPTCHA on a particular site. Alas, but universal solutions do not exist at least because on each resource the protection is unique. Some typical solutions are very rare.

Of particular interest in this regard are the developments of the company CMS Bitrix, which distributes really effective programs that cope with the CAPTCHA on most popular sites. The developers claim that the effectiveness of their creation is within 95%. Depending on the type of protection, its complexity and specific site, the development of methods for its protection can cost you a couple of thousand dollars, or even more.

In addition, on some resources there is so sophisticated protection that it is difficult for a person to unravel!

Can I earn money by entering it?

Beginners are often interested in whether it is possible to earn somehow by entering protective characters. And this is not surprising, because the Internet is full of ads about a set of groups of people who will receive some money, performing the recognition of captcha. Should I contact this?

In our opinion (perhaps, rather subjective), it is not worthwhile to deal with this matter. You will spend a huge amount of nerves, forces and traffic. And the payment for such a "light earnings" is simply amazing: after spending the whole day at the computer, with maniacal perseverance doing driving captcha, you will earn a maximum of a couple of dollars. Do you want it? Certainly not.

Universal output

If we talk about file sharing, then if you regularly upload files, the only reliable way out of the situation is to buy a paid account. As a rule, its cost is quite adequate. By purchasing such a subscription, you will get the opportunity to download any volumes of information quickly and without inconvenience.

How to remove captcha from your blog?

We hope that you have drawn the right conclusions by reading most of our article. So, let's look at how to remove the capture of captcha on the popular Blogger service from the notorious Google company. It's not difficult to do this, and you bring a lot of joys to the visitors of your site.

First go to the "Editor" of your page. In the left column select the item "Settings". It has a section "Messages and Comments". In the field "Use word verification", set the value to "no", then captcha will not be required when entering messages.

What should I do if I can not enter it correctly?

It happens that the program for entering the captcha or the site itself (if you enter the values manually) constantly produce an error. What could be the reason?

First of all, you need to calm down. As a rule, on the right side of any captcha there is a curved arrow. Clicking on it, you update the set of characters that you need to enter to access the site. Using it, you can change a completely unreadable set. Unfortunately, unreadable letters are very common. So, sometimes the difference between the letters "Q" and "G" is completely indistinguishable.

Finally, on many sites you can avoid entering security characters, if you just register on it. Try this method.

That's what captcha is!
