Searle's paper, titled "Dazed & Confused: A Large-Scale Real-World User Study of reCAPTCHAv2," found that Google's widely-used CAPTCHA system is primarily a mechanism for tracking user behavior and collecting data while providing little actual security against bots. The study revealed that reCAPTCHA extensively monitors users' cookies, browsing history, and browser environment (including canvas rendering, screen resolution, mouse movements, and user-agent data) — all of which can be used for advertising and tracking purposes. Through analyzing over 3,600 users, the researchers found that solving image-based challenges takes 557% longer than checkbox challenges and concluded that reCAPTCHA has cost society an estimated 819 million hours of human time valued at $6.1 billion in wages while generating massive profits for Google through its tracking capabilities and data collection, with the value of tracking cookies alone estimated at $888 billion.
