CAPTCHAs allows website administrators to curb unwelcome automated activities, such as spam, DDoS attacks, and sometimes web scraping.ĬAPTCHAs also have secondary purposes. ![]() Originally, they helped to digitize badly-scanned text passages that optical content recognition (OCR) technologies couldn’t crack. Nowadays, we provide free labor for Google’s machine learning algorithms by labeling objects in images. How Do CAPTCHAs Work?ĬAPTCHAs function as a final test to determine if a website’s visitor is human or bot. They appear when a website detects unusual traffic then they present the visitor with a challenge. The exact configuration of a CAPTCHA depends on the webmaster: it can protect the whole website or specific pages.

Here are the combinations you can expect and their frequency: Combination They’re combined whenever fingerprinting or another protection method fails to conclusively prove that a visitor is non-human. Simple trigger + passive + active fingerprinting + CAPTCHAĪs you can see, many websites won’t bother implementing elaborate fingerprint checks. That’s because doing so requires a lot of resources, and it can also harm user experience. ![]()
