Abstract: A method, system, and computer-readable medium for synchronizing policy data on a device based on device usage context. By synchronizing policy data on the device based on device usage context, security, bandwidth and energy efficiency concerns associated with the current data synchronization art by intelligently organizing and prioritizing the updating of policy data in compliance with policy data.

Abstract: Described herein are systems and methods for telecommunications spectrum sharing between multiple heterogeneous users, which leverage a hybrid approach that includes both distributed spectrum sharing, spectrum-sensing, and use of geo-reference databases.

Abstract: Methods and systems described herein relate to enhancing security on a device by configuring one or more software functions in a trusted zone of a processor using object firewalls, IPC mechanisms, and/or a policy engine. An inter-process communication mechanism and inter-process communication bus enable secure inter-process communication between inter-process communication applications within the trusted zone and inter-process communication applications external to the trusted zone. Adapting, filtering, blocking, redirecting, or otherwise modifying inter-process communications is enabled by the inter-process communications mechanism. Modifications may be controlled by a policy engine within the trusted zone.

Abstract: Methods and systems described herein relate to enhancing security on a mobile device. A method for enhancing mobile device security includes providing a trusted zone of a processor, and configuring various items in the trusted zone. Such items may include a specialized debugging interface; a remote auditing tool; an inter-process communication mechanism; a secure daemon; a package manager; a virtual machine, a configuration function, a device management system, touch screen management software, and a geo-localization function.

Abstract: Methods and systems described herein relate to enhancing security on a mobile device. Systems and methods for mobile device security include restricting access to network resources via an in-location access point device, based on whether the mobile device is in proximity of the in-location access point device.

Abstract: Methods and systems described herein relate to enhancing security on a device by enforcing security and access control policies on privileged code execution.
