Text CAPTCHA has been an effective means to protect online systems from malicious attacks. However, nearly all the Text CAPTCHA designs are based on English characters, which may not be the most user-friendly option for non-English speakers. Therefore, there is an increasing interest in designing local-language CAPTCHAs, which are expected to be more usable for native speakers. However, systematic studies on the usability of localized CAPTCHAs are rare, and a general procedure for the design of usable localized CAPTCHA is still unavailable. Here, we comprehensively explored the design of CAPTCHAs based on Chinese characters from a usability perspective: a usability comparison of CAPTCHAs based on Chinese and English characters, then the evaluation of intrinsic design factors of Chinese CAPTCHAs. It's found that Chinese CAPTCHAs can be equally usable comparing with alphanumeric ones. Meanwhile, guidelines for designing user-friendly Chinese CAPTCHAs are also presented. Those design practices are further summarized as a general procedure which is expected to be applicable for the design of CAPTCHAs based on other languages.
