Abstract
Several embodiments include a mobile device that uses a media file to render a passcode entry interface. The passcode entry interface can have an assigned location of an input element that corresponds to an inputtable value in the passcode entry interface. The media file can include a visual depiction having the input element at the assigned location. In several embodiments, the media file does not store the association between the assigned location and the inputtable value. The assigned location corresponding to the inputtable value can be separately stored. The mobile device can receive a coordinate of a touch event on the passcode entry interface. To determine a passcode entry based on the touch event, the coordinate can be compared against the separately stored assigned location to determine a corresponding input value to the coordinate.
