Methods, systems, apparatuses, and computer program products are provided for enabling devices to determine the time zone in which they are located. A mobile device may receive location information from one or more sources. Based thereon, the current location of the mobile device may be determined in terms of latitude and longitude. The indication of the current location may be converted to an index value according to a Hilbert curve (or other space-filling curve), and the index value applied to a time zone index file to determine the local time zone. A time zone setting of the mobile device may be updated accordingly. Furthermore, 'geofencing' may be used by the mobile device to detect movement towards and through a time zone boundary, leading to a new time zone determination being initiated.

Automatic time zone detection in devices

One or more techniques and/or systems are provided for dynamically maintaining user centric data. For example, a data provider app may have knowledge about user centric data associated with a user (e.g., a social network app may have contact information for a social network friend of the user). A user centric profile may be defined for the user centric data based upon information provided by the data provider app (e.g., a contact card may be generated for the social network friend). Responsive to receiving a request for the user centric profile from a requestor app (e.g., an event planning app), the user centric profile may be exposed to the user but not to the requestor app for security and/or privacy purposes. For example, an operating system may present at least some of the user centric profile within an operating system user interface.

User centric data maintenance

Systems, methods, apparatuses, and computer program products are described for checking the integrity of applications installed on a computing device and preventing the launch of applications that appear to have been tampered with or modified. In accordance with embodiments, the content of an application is validated at the time the application is to be launched, but before the launch has actually occurred. In accordance with additional embodiments, integrity protection can also be extended to content that is generated by an application (e.g., documents or other files generated by the application), thereby enabling applications to write their own files and data with the same degree of integrity protection.
