The first and second generation of CAPTCHAs had a paradoxical logic that stated humans, comparing to machines, have superiority in recognizing images, numbers, or various objects. Account Takeover: Prevents brute force and credential stuffing attacks and protects account security.Spam Email: Prevents the spread of spam email.Fake Comments: Prevents bots from artificially inflating or deflating public endorsements.Abusive Traffic: Prevents platform resources from being maliciously wasted.Bonus Abuse: Prevents attackers from automatically acquiring bonuses and gifts.Ticket Scalping: Prevents fraudsters from automatically obtaining tickets for resale.Web Scraping: Prevents valuable content theft.CAPTCHA prevents digital criminals from automating their fraudulent tasks by ensuring there is a real human behind each request, thus effectively prevents scammers from scaling their illicit operations and committing online fraud and abuse. The digital-criminals use bot programs to commit fraud and abuse through automation of tasks in a malicious way such as credential stuffing attacks, email or comment spam, online poll fraud, etc. Without CAPTCHA, spam and abuse would take over most of the platforms, and the internet ecosystem as we know today would not exist. CAPTCHA is a gateway that protects websites, mobile APPs, and APIs from these bad bots by presenting a challenge-response that is hard for computer programs to bypass and easy for human users.
If you write a program that automatically generates such a test on the internet, then you got yourself a CAPTCHA: Completely Automated Public Turing test to tell Computers and Humans Apart.Ĭaptcha test is a challenge-response -often in the form of a cognitive task- that requires user interaction to determine whether or not the user is human.Īutomated computer programs -bots- can be used for malicious activities such as spam, brute-force attacks, competitive data mining, etc. Therefore a reverse Turing test is a human convincing a computer that it is not a computer. Turing test is a method of inquiry in artificial intelligence where a computer has to convince a human that it's a human. Lost Ark Plagued by Spam Chat: That's Where You Need CAPTCHAsĬAPTCHA is a module used in websites, mobile apps, and APIs to distinguish automated computer programs from genuine human users.ĬAPTCHA is an acronym for “ Completely Automated Public Turing test to tell Computers and Humans Apart.” GeeTest Named as Selected Vendor in Forrester Now Tech: Bot Management, Q4 2021
