Claim One:
1. A method for determining that an unknown user is a known user of a touchscreen device, the method comprising: receiving an input via a touchscreen device from an unknown user during an activity performed by the unknown user; determining, during the activity performed by the unknown user, a spatial orientation of the touchscreen device on an x-y-z axis in association with the input received from the unknown user; performing a statistical evaluation whereby one or more features of the input received from the unknown user, in combination with the spatial orientation of the touchscreen device associated with the input received from the unknown user, are compared with one or more features of analogous input, previously received from a known user via the touchscreen device during an activity performed by the known user, in combination with a spatial orientation of the touchscreen device on the x-y-z axis associated with the input previously received from the known user during the activity performed by the known user, wherein the input previously received from the known user and the spatial orientation of the touchscreen device associated with the input previously received from the known user are stored in a profile associated with the known user; and determining, based on the statistical evaluation, a probability that the unknown user is the known user.
