Abstract:
1. A touch-based authentication method of a mobile device comprising: recognizing a tactile pattern on a touch screen without a visual aid as an unlocking gesture and wherein the tactile pattern is independent of a scale value and a position value on the touch screen; storing the unlocking gesture to a memory of the mobile device; associating another tactile pattern on the touch screen with the stored unlocking gesture; transforming the mobile device from an initial state to an unlocked state to operate as a the telephonic communication device based on the association between the another tactile pattern and the stored unlocking gesture and accessing a contact list and a greeting message based on a user profile; associating a set of bookmarks based on the user profile of the telephonic communication device associated with the unlocking gesture to enable customized settings on a browser application of the mobile device; determining that the tactile pattern is placed at multiple distinct locations on the touch screen while recognizing the tactile pattern as the unlocking gesture, wherein the multiple distinct locations are simultaneously and serially placed; designating a region of the touch screen as available to receive the another tactile pattern, such that the another tactile pattern is algorithmically determined to be the unlocking gesture when recognized in the designated region; determining a duration of the another tactile pattern at a particular location of the touch screen to determine whether it is the unlocking gesture; and determining that a total time to create the another tactile pattern is within a permitted amount of time when determining whether it is the unlocking gesture.
