In the past era many of the authentication method can be introduced, but the most common and convenient method for the authentication is traditional alphanumeric password. For security reason the development of graphical passwords as an alternative. They overcome the drawback of traditional password but remains vulnerable to spyware attack.It propose a graphical password scheme by using CAPTCHA (Completely Automated Public Turing tests to tell Computers and Humans Apart). Spyware is software that aims to gather information about a person or organization without their knowledge and that may send such information to another entity without the consumer's consent, or that asserts control over a computer without the consumer's knowledge.
