Agar apko Artificial Intelligence CAPTCHA koi bhi jankari nahi hai. To aap Bus Is post ko padhe Kyoki aap mai apko Artificial Intelligence CAPTCHA ke bare me Puri Information Details me bataunga. And sath me ye bhi bataunga ki aap Kaise Artificial Intelligence CAPTCHA bna sakte hai.

AI CAPTCHA Kya Hota Hai And Ye Kaise Kam Karta Hai:
Sabse hum baat akrte hai ki Artificial Intelligence CAPTCHA kya hota hai. Friends basically CAPTCHA ka matlab hota hai “Completely Automated Public Turing test to tell Computers and Humans Apart”. And iska use Human aur Machine (Computer) ko alag karne ke liye kiya jata hai.
CAPTCHA Verification ka main aim hai. Human ko verify karna aur Website ko Hacker se bachna. CAPTCHA Code ka Basic use Spam aur Website Protection ke liye hota hai.
Example ke taur par Man lijiye koi Hackers, Machine (Computer) ka use karke Google Gmail par account bnana chahta hai. Machine (AI Human, Computer ) Gmail Account banane ke liye Jaruri sabhi Information ko Fill kar deta hai. But jaise hi Machine(Computer) CAPTCHA ko Verify nahi kar pta hai. Kyoki machine, Human ki Tarah Soch nahi sakta hai.And agar aap CAPTCHA ko Verify karna chahte hai to apko ke ander Sochne ki Capability honi chahiye.
Example ke taur par agar ek Image CAPTCHA ko Verify karna hai. And CAPTCHA Verification ka Question hai “Select Store Front Image”.
Agar aap ek Insan hai to aap ko CAPTCHA Image me dekhker aap soch sakte hai, ki Kaun sa image “Store Front Image” hai. But EK Machine (Computer) ye kaise soch sakta hai ki CAPTCHA me diya gya image “Store Front Image” hai. yah koi aur Image hai.
Iska Matlab aap Machine ka use karke Gmail par Account nahi bna sakte hai. Google Security ke anusar Gmail par keval Ek Human hi Account bna sakta hai. Agar apko detail me pta karna hai ki Google CAPTCHA ka use kyo karta hai to iske liye aap neeche diye gaye link par click kare.
