By choosing image hints automatically, the user does not need to be burdened with unlimited possibilities for hinting. With gesture recognition and length (i.e. number of strokes) guidance, the effort for precision encoding/recall is also significantly reduced. Drawing on Signet also nods at the increasing popularity of touchscreen devices and answers the frustration that is precision typing something complex on touchscreens. Images work as if they were meant to hide a message waiting for the user to uncover and use, thus making them a personal and meaningful cryptography solution. Spending time analyzing allows for deeper memory encoding and the multiple images can have a pleasurable surprise effect in users. All image hint concepts have also proven the power of visual memory in remembering. One of the key to the success of Signet is the combination of visual recall and recognition features in a lightweight manner. Signet also embraces the reality of authentication nowadays. Most passwords are for Internet services and therefore there is no hesitation in relying on a solution that uses the power of cloud computing for guiding the user who still keeps privacy under control.
