Nowadays Internet Polls are becoming more and
more important as they are being used on a large scale.
Being a web application a poll can suffer from a variety of
attack. Recently automated web tools are used to attack
Internet Polls in order to alter the results via automatic voting.
Several protection methods introduced to stop automatic
voting including IP Locking, cookie-based, and Human
Interaction Proof. In this article, existing methods for
protection are examined and also we have proposed an
innovative solution, which considerably increases the security
of Internet polls and the reliability of their results. The
proposed solution has two phases: the construction phase in
which the poll content and CAPTCHA test are created and the
utilization phase, in which vote counting operation is done. The
CAPTCHA that is used in the proposed method is an image based CAPTCHA. For the aim of voting, an Internet user has
to drag his or her desired poll option expressed in form of
movable text object and drop it on to the picture of an object
indicated by the CAPTCHA. The proposed method is fair,
robust, and resistant. One of the main advantages of the
method is that it can be used by all ages
