Marque CAPTCHA- CAPTCHA Implementation Based on Motile Characters

CAPTCHA is a challenge-response test developed to ensure that the user is human and not an automated computer software program (known as bot). CAPTCHAs are used to prevent automated software programs or bots from performing actions that would degrade the quality of a given system. Internet today has occupied a major part in our everyday lives. Several services, including search engine, email and web board on internet are made available to the users without any cost indirectly making them extremely vulnerable. Bots are developed with purpose to use such services illegally and automatically. Therefore today almost all websites deploy CAPTCHAs on their sites in order to counter attacks from automated bots. Unfortunately there are several bots available to break CAPTCHAs. Therefore several alternative methods of implementing CAPTCHAs have thus been developed but making it difficult for the users to decipher the code provided in CAPTCHAs. We therefore propose a new system of CAPTCHA with an aim of providing enhanced security from the bots and at the same time being user-friendly. The proposed CAPTCHA system is based on marque type motile characters. As there is animation included in the form of motile characters, it will be difficult for the bots to attack this type of CAPTCHA meanwhile being easier for the users to decipher.
