摘要：Use of text-based passwords is common authentication system. This conventional authentication scheme faces some drawbacks with usability and security issues that bring troubles to users. For example, user tends to pick passwords that can be easily guessed. On the contrary, if a password is hard to guess, then it is often hard to remember. An alternative system is required to overcome these problems. To deal with these drawbacks, authentication scheme that use image as password is proposed. In this paper, we combine the features of these three methods. Our proposed system is mainly the combination of Persuasive Cued Click Points and click-draw based graphical password scheme (CD-GPS). In this, users first choose an ordered sequence of 5 images and then select single image to click-draw their secrets. On remaining 4 images we select click points using features of PCCP (viewport and shuffle button). At the time of login images appear as per the decided sequence. For login user should click on the images for which we used features of PCCP for password creation and user should draw a secret on the previously selected image. By adding feature of secret drawing to PCCP , attackers fails to know that there is use of secret drawing technique on a image in between these images, unfortunately if they knows about secret drawing, they don’t get exact idea that on which image secret has to done .Our proposed system provides higher security than other techniques.
