Originální abstrakt

For nearly a two decades, development of new mechanisms for securing web applications from unwanted traffic caused by automated programs called CAPTCHA schemes are under constant improvement. As significant fraction of this defense mechanisms are based on known issues of Optical Character Recognition methods, attackers must help to improve current algorithms to overcame the security measures. The focus of this work is to present an idea of randomly generated pseudo characters for purpose of forming the text-based Captcha challenges. The main part of this article is dealing the problem of transforming the common computer fonts into abstract characters.
