Design of a drag and touch multilingual universal captcha challenge

Abstract

In order to protect sensitive data from bots, service providers protect their Web sites through some of the CAPTCHA tests. This test ensures that protected resources are accessible to only legitimate human users and no computer program (bot) gets their access. With a growing number of Web sites and Web portals offering more and more sensitive data for access by its legitimate human users coupled with the advances in techniques used to break CAPTCHA challenges, more robust and complex CAPTCHA challenges were developed. Though some of these tests offer the desired level of security, however, they often are inaccessible to a large population of the Web sites and also suffer from other usability issues. This paper presents a new CAPTCHA challenge based on the mouse motion event and is also usable on touch screens. This test can be made highly secure, lightweight, multilingual, and universal and does not suffer from any usability issues. The test can be coded for English or any other regional language, therefore, overcoming the language barrier of the CAPTCHA challenges. Experimentation with the proposed model implementation of the CAPTCHA challenge has proved its robustness, diversity, lightweight, and usability.
