Abstract
A method is provided for generating a human readable passcode to an authorized user including providing a control access datum and a PIN, and generating a unique machine identifier for the user machine. The method further includes modifying the controlled access datum, encrypting the controlled access datum using the PIN and/or a unique machine identifier to camouflage the datum, and generating a passcode using the camouflaged datum and the PIN and/or the unique machine identifier. A mobile user device may be used to execute the method in one embodiment. The passcode may be used to obtain transaction authorization and/or access to a secured system or secured data. The unique machine identifier may be defined by a machine effective speed calibration derived from information collected from and unique to the user machine.
