sneakerbots) or common open source solutions (e.g. These communities gravitate towards common targets (e.g. A bot builder’s experienceīot builders operate as niche communities, assisting each other and sharing knowledge. The consumer is the product, and the currency is time and patience. All of these services leverage human interaction to train a data model for bot detection. Other variations of “modern” CAPTCHA require users to rotate images and move puzzle pieces. Understanding and limiting the differences between headless chromium versus chrome is a (dark) art that enables bots to obtain the same risk score as humans. Google’s reCAPTCHA v3 results in less human impact, but the bots now have a security control that they can evade. Google’s latest (paid) version acknowledges user frustration however, it now requires the application owners to create and manage the risk scores that differentiate humans and bots. Google, amongst a group of other vendors, launched new and improved CAPTCHAs! I have an idea: Let’s build a new CAPTCHA! ReCAPTCHA v3… The rationale that it is cheap, easy, and doesn’t impact performance metrics fails to acknowledge the overall session latency, UX impact, and session abandonment. This relies on consistent human interpretation, which can be limited in many different ways. This is true, too, of the game-like CAPTCHAs (spin the image, etc) where the puzzle is implied in the visual rather than text. Ultimately, all image-based CAPTCHAs are limited by the human versus bot conundrum: how can you make an image test that is consistently too hard for bots, but easy enough for humans to pass? A classic see-no-evil, hear-no-evil scenario. They are black box solutions: no config, no decisions, and limited visibility of the impact on humans or the bots that are getting through. ReCAPTCHA solutions that require human interaction provide application builders and owners an easy out.
Why do 47% of the websites that use Google’s reCAPTCHA service use the “Pick the traffic lights” version? This leads us to an interesting question: Given that every human on the planet hates them and they aren’t effective at blocking bots, why are CAPTCHAs still a thing? The Classic “Please select the photos of the traffic light” CAPTCHA
The biggest of them all, Google’s reCAPTCHA, is used by more than 6.3 million websites. At the time, it was a groundbreaking solution to a niche problem: preventing bots from entering URLs into the web search engine.įast forward to 2021, and there are more than 20 different CAPTCHA vendors. The team at AltaVista (RIP) invented the CAPTCHA in 1997.
