    (Wydawnictwa AGH, 2008) Laskowski, Maciej
    Due to rapid development of Internet, Web 2.0 in particular, websites need to be protected from automated (and undesired) usage of offered services (eg. mass creating of email accounts) or publishing content. Nowadays, majority of websites use CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) technology, which was invented in late 90s. This solution is often criticized as 'user unfriendly'. In this article usability of chosen CAPTCHA implementations is tested. Token-generation techniques, their advantages and disadvantages are considered. Alternatives for existing solutions are described.
