Abstract: The CAPTCHA is used to provide the security against the malicious software by generating a test which only a human can complete. The CAPTCHA stands for Completely Automated Public Turing test to tell computer and human apart. Currently, we are using CAPTCHA are image and text-based data. The reusable CAPTCHA security engine will provide a better way to generating the data for CAPTCHA and will increase the difficulty in bypassing the system by use of improved algorithm. CAPTCHAs are designed to prevent bots – programs that pose as humans on the Internet – from abusing internet services. Bots, driven not to dominate but to sell, sign up for thousands of free email accounts every minute, sending millions of spam messages from them. Such reading-based CAPTCHAs exploit the large gap between humans and machines in their ability to read images of text.
