![]() ![]() Enter Invisible reCAPTCHA (or reCAPTCHA v3), which uses an internal scoring system to detect abusive traffic and requires no additional user input. While v2 was pretty effective, Google continued to develop a more robust way of curbing spam. Humans tend to move the mouse in curved, irregular patterns, while bots move the cursor in straight lines. Google then created the reCAPTCHA v2, which includes the “I’m not a robot” task - website visitors simply check a box to proceed, and the CAPTCHA detects bots by tracking mouse movement toward the box. Invisible reCAPTCHA automatically snuffs out spam and allows visitors to enjoy an uninterrupted browsing experience without the irritating tests. ![]() ![]() However, this version of reCAPTCHA has been phased-out by Google. Why? The first iteration of Google reCAPTCHA required visitors to identify certain images and interpret distorted text, like in the example above. This complexity led to actual humans finding it difficult to pass tests like these:Ĭan you read that word? I’m not sure I can.Īfter several iterations of its own CAPTCHAs (called “reCAPTCHAs”), Google introduced Invisible reCAPTCHA. While bots learned to simply bypass CAPTCHA more often than not, the program grew more complex to prevent them from infecting websites and crashing servers. However, early iterations of CAPTCHA failed to keep up with the evolution of modern technology. The first CAPTCHAs were introduced in 1997. To understand what sets Invisible reCAPTCHA apart, let’s look back at what led up to this technology. ![]() Because of this, visitors will only need to solve a CAPTCHA problem if their browsing patterns appear suspicious. This technology uses machine learning and risk analysis techniques to analyze web browsing behavior. Invisible reCAPTCHA is a Google CAPTCHA service that identifies spam traffic without additional input from visitors. ![]()
