FacePattern: A New Technique for better Graphical Password

Computer Engineering

This concept commencing of user producing of passwords without system being providing of hints to produce passwords, the examples of pure recall technique are Draw-A-Secret technique, Grid selection, and Passdoodle. Here, we discuss two types of picture password techniques: reproducing a drawing and repeating a selection Jermyn, et al. proposed a technique, called “Draw-a-secret (DAS)", which allows the user to draw their matchless password. A user is asked to draw a simple picture on a 2D grid using a stylus or mouse. A drawing can consist of one nonstop pen stroke or preferably several strokes separated by \pen-ups" that restart the next stroke in a different cell. The coordinates of the grids occupied by the picture are stored in the order of the drawing. During authentication, the user is requested to re-draw the image. If the drawing touches the same grids in the same sequence, then the user is authenticated. In this type of system the brute-force attack is possible and the impact of password length and stroke-count as a complexity property of the DAS scheme. Recall-based graphical password systems are occasionally referred to as draw metric systems because users recall and reproduce a secret drawing.
