A CAPTCHA is a type of challenge-response test used to determine whether or not the user is human. The term stands for "Completely Automated Public Turing test to tell Computers and Humans Apart."
CAPTCHAs are often used to prevent bots and automated scripts from accessing websites or performing certain actions, such as creating multiple accounts or spamming online forms.
They typically involve displaying a distorted image of letters and numbers, which the user must enter correctly in order to prove that they are not a bot.
What are the Benefits of captcha?
CAPTCHAs provide several benefits, including:
Preventing automated bots and scripts from accessing a website or performing certain actions: This is the primary purpose of CAPTCHAs. By requiring users to prove that they are human, CAPTCHAs can prevent bots from creating fake accounts, spamming online forms, and performing other unwanted actions.
Reducing spam and abuse: CAPTCHAs can help to reduce the amount of unwanted messages and content on a website, such as spam comments or fake reviews.
Improving website security: CAPTCHAs can help to protect a website from certain types of cyberattacks, such as brute-force attacks and denial-of-service attacks.
Improving user experience: CAPTCHAs can help to ensure that users are interacting with a real website, rather than a fake or phishing site.
Protecting user data: CAPTCHAs can help to prevent bots from scraping user data from a website, such as email addresses or personal information.
However, it's worth noting that CAPTCHAs can also have drawbacks, such as making it harder for some users, such as visually impaired individuals, to access a website.
