Cursor CAPTCHA — Implementing CAPTCHA using mouse cursor

Abstract

With the growing use of Internet and its services, a large number of organizations are making use of it to provide and seek information of the people using those services. This has raised the chances of attacks on such services by interrupting them sending multiple requests to the servers providing these services programmatically. CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) provides a way to differentiate users into humans and bots, or computer programs. This paper includes a new technique that utilizes image from custom mouse cursors and outperforms some most popular CAPTCHA techniques such as Text - based CAPTCHAs and previous Image - based CAPTCHAs.
