Number of graphical password scheme has been proposed as options to traditional to text password authentication, namely a new family of graphical password system for Captcha technology with the level of security. We propose a new scheme using CAPTCHA (Completely Automated Public Turing Tests to Tell Computers and Humans Apart) that continuing the advantages of graphical password system; Graphical password using Captcha (RPuC) is a both Captcha and graphical password scheme, RPuC covers a number of security problem altogether, such as online guessing attack, relay attack and shoulder-surfing attacks. The level of security maintained and is improved here by the level Captcha we also developed the primitives options for securing the password and for uploading or downloading the data or file from server. Moreover, some primary tries out are conducted and the outcome indicate that the usability should be improved in the future work.
