A captcha is an image containing a barely visible code word for an automated Turing test to distinguish between computers and humans . Captcha stands for “ Completely Automated Public Turing test to tell Computers and Humans Apart ”. Specifically, by requiring the input of code from this distorted image, humans and computers can be distinguished. So what are the recognition factors when encountering Captcha is used to differentiate between humans and computers Captcha is used to differentiate between humans and computers What are the characteristics of Captcha? Captchas are often written very difficult to read Captchas are often written very difficult to read Made in a distorted, unclear way Usually can only be read with the human eye The “click here if you are not a computer” checkbox can be used to distinguish between humans and robots, but it is not a Captcha. How does Captcha work? Computers cannot read Captchas like humans Computers cannot read Captchas like humans Captcha operates on a very basic principle of using human language and slang rules, which computers and the internet cannot understand. Thanks to that, Captcha can help distinguish very accurately between humans and computers.
Prevent malware, robots, and computers programmed to attack the system. Entering Captcha will stop illegal intrusions because they cannot pass this verification step. According to recent statistics, people have the ability to enter the correct British Student Phone Number List Captcha at a rate of 80%. Meanwhile, this ability in pre-programmed computers or robots is only 0.1%, extremely low. Why should websites use Captcha? Captcha brings many security features to the website Captcha brings many security features to the website Nowadays people no longer feel bothered when they have to stop to verify Captcha. All large and small services today use Captcha testing . For example, big companies like Google, Gmail, Yahoo,... A question that arises is "Why should websites use Captcha?".
As shared about how Captcha works above, it can be seen that the step of confirming images with Captcha will stop the intention of attacking the website from malicious software and robots. Anti-Spam : is one of the simple but popular attack methods. Spam comments, mass account registrations, and virtual bulk purchases often occur. Using Captcha will force attackers to be real people, which makes them take a lot of time to execute. Protecting information and data : Captcha today is a form of protecting data ports on websites. Prevent automatic access from computers and robots to protect important information on the website. Guaranteed real interaction : What if you run a survey on a website if there are computers involved? Of course, the results will be skewed, as the number of large computers will take up as much traffic as it slows down the web when real people access it.
