A Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) is a widely used security mechanism for constructing a high-confidence proof that the entity interacting with a remote service is actually a human being. We conducted an empirical study aiming to compare users efficiency and effectiveness in solving localized vs. Latin-based text CAPTCHA challenges. The study embraced a between-subject design using a CAPTCHA mechanism that produced text challenges from different alphabets (Latin and non-Latin). In total, 253 non-native English speakers participated in the context of an ecological valid experimental design. The participants provided 494 CAPTCHA challenge responses. The analysis of the responses draws useful insights that can be utilized in the design of secure and usable CAPTCHA mechanisms.
