Researchers have proposed a novel CAPTCHA system that leverages the unique timing characteristics of a graphics processing unit (GPU) during WebGL rendering. This method aims to differentiate between human users and automated bots by analyzing render-timing dynamics, rather than identifying specific hardware or relying on behavioral analysis. Initial tests indicate that software-rendered automation, a common adversary, exhibits significantly different timing patterns compared to genuine GPUs, suggesting a potential for an AI-resistant security measure.
