Abstract: A method, system, and media are provided for enhancing viewability of information presented on a mobile device. The media includes presenting a user interface on a mobile device that includes foreground information that overlaps a background image. The background image may be converted into a first set of color values and the foreground information into a second set of color values. A dominant color may be determined for the background image and foreground information. The dominant colors may be used to calculate a contrast ratio that may be compared to a threshold value. At least a portion of the color values may be modified when the contrast ratio is less than the threshold value. A set of modified color values may then be derived and a modified presentation may be presented to the user that includes the modified color values.

Abstract: Methods are disclosed for determining, based on a pass code inputted by a user, whether the user can access a particular feature of a mobile device. Features may include access to the device itself, products, services, applications, or the like. The mobile device requests access to the feature, and is sent display information for a plurality of icons, which indicates where each icon is to be displayed. An ordered selection of icons is received to determine whether the ordered selection matches a predetermined ordered selection. If they match, the user is allowed to access the feature of the mobile device.
