Abstract:
1. A method for limiting access to an asset, comprising: creating a graphical passcode by: receiving, via a touchsurface, a plurality of inputted graphical passcodes from a user to be used in generating a passcode template, wherein each graphical passcode comprises at least one swipe and at least one tap; for each of the plurality of inputted graphical postcodes: measuring various parameter values associated with each touchsurface touch of the inputted graphical passcode, the various parameters comprising time, X-axis position, Y-axis position and one or more of pressure, speed, and contact area; and storing the measured parameter values in memory; analyzing the stored measured parameter values of each of the plurality of inputted graphical passcodes to determine baseline passcode parameters and an envelope about x-axis position and y-axis position baseline passcode parameters that circumscribes at least a portion of the plurality of inputted graphical passcodes, storing in memory the baseline passcode parameters and envelope to be used as the passcode template; receiving via the touchsurface a subsequently inputted graphical passcode from the user; measuring various parameter values associated with each touchsurface touch of the subsequently inputted graphical passcode, the various parameters comprising time, X-axis position, Y-axis position and one or more of pressure, speed, and contact area; expanding the envelope of the graphical passcode upon detection of acceleration consistent with a bumpy environment to make it easier for a user to enter a passcode that complies with authentication criteria; comparing the measured parameter values of the subsequently inputted graphical passcode to the passcode template stored in memory; and granting access to the asset if the measured parameter values of the subsequently inputted graphical passcode substantially matches the passcode template, wherein the subsequently inputted graphical passcode substantially matches the passcode template when the subsequently inputted graphical passcode parameters fall within the stored envelope.
