What types of Captcha are there?
Today security tests based on tests to differentiate humans from computers have become part of our daily lives, created in order to protect our information, there are different types, seven that we can name: mathematical calculation, word play, answers with time limit, hidden fields, no captcha recaptcha and image recognition or visual captcha.
Of automated solutions
They are those that have automatic response challenges , that is, they are developed with resolution algorithms, as in the case of the ‘no captcha recaptcha’ which consists of clicking on ‘I am not a robot’ and gives us access through the touch imprecision, since a robot would touch exactly in the center.
Of human work
On the other hand, these do have user intervention, since they consist of completing small tests such as recognizing words in an image, identifying objects or distinguishing sounds, they are the simplest Captcha to develop and therefore cheaper than the automatic ones.
What is the use of hCAPTCHA?
hCAPTCHA is a totally free captcha service for all its users , it is also the most used independent service of this type in the world.
In addition, you will notice that hCAPTCHA uses challenges that are easy for humans to perform, but not for bots. When collecting data that is difficult to label in machine learning problems and employing it to differentiate whether a visitor to a web page is a human or a bot.
This hCAPTCHA service does not present differences to the user, it will continue to choose images where an object that is requested is found, for example, cars, bicycles, traffic lights. Eventually it will ask the user to classify an object within an image or to choose a category for a photograph, being simple tasks for anyone.
What are the differences between hCAPTCHA and reCAPTCHA?
Recently reCAPTCHA made the announcement that it was going to charge for the use of its service , it is not yet known if there will be a price rate according to the user. But definitely, it is something that took everyone by surprise and that prompted many to seek an alternative to this problem.
hCAPTCHA is an initiative that provides the same services as Google’s reCAPTCHA with the difference that its main objective is the privacy of users and that it does not charge web pages for their service, on the contrary, it pays them.
How do you operate for the verification of human use on the internet?
Captcha that require user intervention when solving have become very popular in recent years, since being simpler than automatic ones they end up being cheaper and more accessible for web page owners.
To verify the effectiveness of these captcha, before going to the market, the programmers upload them to web pages where people solve them one after another , receiving a small bonus in pennies on the dollar for each one they solve. A very popular page dedicated to offering this job is ‘RUCaptcha’.
How they help combat bots on web pages
The incursion of bots and hackers on the internet should be a matter of concern for everyone. You don’t have to be a web page administrator to watch over your data and security, even social media consumers must. We always recommend using a strong password, which combines the use of uppercase, lowercase, and alphanumeric letters so that you can protect your social networks to the maximum .
Keep bots away from your website
If you are the owner or administrator of a web page, one of the concerns that surely should not let you sleep at night is How to keep your page safe from bot attack? There are several ways to achieve this, the first is to always have users and keys that are difficult to decipher.
Another option to keep your forms safe is adding challenges, and don’t be scared, you don’t have to develop a program or anything like that, actually the process to add reCAPTCHA to your WordPress website is very simple, and it won’t take you more than 30 min implement it.
And it is that not only the forms are a way to try to access your page or implant malware. It can also be through the comments and it is at that moment where it will be useful to have an anti Spam tool such as reCAPTCHA or hCAPTCHA. And one last recommendation is that you activate plugins that automatically block login attempts or comments on your post.
How to earn money with hCAPTCHA?
One of the most striking attractions offered by this initiative is to earn money for each challenge solved by users, and that is that they do not sell the data to advertising companies; Instead, they use a system called Human Protocol , through which they train machine learning models.
By challenging users and tagging large amounts of data reliably and affordably, this information enables machine learning models to be more effectively trained.
Then web pages will receive Human Tokens (HMT) every time users complete a challenge, and machine learning companies pay Human Token (HMT) to tag their data. All through the Ethereum blockchain. hCAPTCHA also offers the ability to donate those proceeds to a charity of your choice.
