  • Despite several attacks have been proposed, text-based CAPTCHAs are still being widely used as a security mechanism. [...] Key Method Unlike prior machine-learning-based approaches that need a large volume of manually-labeled real captchas to learn an effective solver, our approach requires significantly fewer real captchas but yields much better performance. This is achieved by first learning a captcha synthesizer to automatically generate synthetic captchas to learn a base solver, and then fine-tuning the…Expand Abstract
