Password protection using spatial and temporal variation in a high-resolution touch sensitive display

摘要

A wearable mobile computing device/appliance (e.g., a wrist watch) with a high resolution display that is capable of wirelessly accessing information from the network and a variety of other devices. The Wrist Watch device/appliance includes a password authentication system for enabling access to secured data stored therein. The authentication system includes a user interface display having a touch sensitive panel for detecting physical user interaction therewith and generating signals accordingly. The Wrist Watch device/appliance generates a sequence of one or more images for display via the user interface, the images of a sequence including that users' password elements which are flashed randomly at different interface display locations and varied temporally. A processor device receives signals generated in accordance with user interaction with the touch sensitive panel at locations corresponding to the locations of a flashed image of the sequence that matches each element of the user password in order to provide verification of the password when all elements of the password have been detected.
