Can robots read CAPTCHA?

Actually, bots can get around a CAPTCHA. Problem is that the bot needs to know which CAPTCHA system is used and how to proper fool the system to bypass it. In the past, CAPTCHAs would use text in an image but OCR software is capable of reading it.

How does reCAPTCHA pictures work?

reCaptcha gives the same image to a number of users, and if they all agree on what it says, then the picture becomes training data for Google’s AI. From wikipedia: The reCAPTCHA service supplies subscribing websites with images of words that optical character recognition (OCR) software has been unable to read.

Why are CAPTCHAs hard for bots?

Warped words are difficult to read. For many users, they are in an unfamiliar alphabet and have to be typed with a different keyboard setting. And for people with dyslexia or sensory disabilities, text- or image-based Captchas can be flat out impossible to solve.

Why are CAPTCHA images so depressing?

CAPTCHA pictures are often shot from extremely awkward angles — angles that we humans would never pick. When you or I take a picture, we typically shoot from the view from our eyes. We’re usually holding the camera; our body is inherently involved in framing the view.

Why do we use CAPTCHA?

CAPTCHA stands for the Completely Automated Public Turing test to tell Computers and Humans Apart. CAPTCHAs are tools you can use to differentiate between real users and automated users, such as bots. CAPTCHAs provide challenges that are difficult for computers to perform but relatively easy for humans.

What is CAPTCHA and how does it work?

Granted, the creators left out a few words to make the acronym work; “CAPTTTTCAHA” isn’t quite as catchy. Some modern CAPTCHAs work by asking users to click certain pictures. For instance, one popular CAPTCHA tool often asks users to “click all of the images that include a street sign.”

What is Recaptcha and how does it work?

reCAPTCHA is more advanced than the typical CAPTCHA tests. Like CAPTCHA, some reCAPTCHAs require users to enter images of text that computers have trouble deciphering. Unlike regular CAPTCHAs, reCAPTCHA sources the text from real-world images: pictures of street addresses, text from printed books, text from old newspapers, and so on.

How do bots get past CAPTCHAs?

Some bots can get past the text CAPTCHAs on their own. Researchers have demonstrated ways to write a program that beats the image recognition CAPTCHAs as well. In addition, attackers can use click farms to beat the tests: thousands of low-paid workers solving CAPTCHAs on behalf of bots.

Why are CAPTCHAs so hard to read?

CAPTCHAs frustrate users because they’re purposely difficult to read. However, there’s a method to the madness. CAPTCHA tests purposely have poor “segmentation,” which is the ability to separate letters from one another. The letters also vary in style dramatically, as computers cannot easily identify these variables.
