摘要

CAPTCHA现在几乎是一种标准的安全技术，并在商业网站上得到了广泛的应用。可用性和健壮性是CAPTCHA的两个基本问题，它们经常相互关联。本文讨论了在设计验证码时应该考虑和解决的可用性问题。其中一些问题是直观的，但其他一些问题对健壮性(或安全性)有微妙的影响。本文还提出了一个简单而新颖的验证码可用性检验框架。

Usability of CAPTCHAs or usability issues in CAPTCHA design

CAPTCHA is now almost a standard security technology, and has found widespread application in commercial websites. Usability and robustness are two fundamental issues with CAPTCHA, and they often interconnect with each other. This paper discusses usability issues that should be considered and addressed in the design of CAPTCHAs. Some of these issues are intuitive, but some others have subtle implications for robustness (or security). A simple but novel framework for examining CAPTCHA usability is also proposed.
