Abstract: An authorization engine is provided in a remote device for mobile authorization using policy based access control. To ensure that remote devices can enforce consistent authorization policies even when the devices are not connected to the server, the remote device downloads the relevant authorization policies when the business objects are downloaded and enforces the policies when operations are invoked. The memory footprint of downloadable authorization policies is reduced to fit onto a resource-constrained remote device. A policy evaluation engine interprets and enforces the downloaded policies on the remote device using only the limited computational resources of the remote device.

Abstract: A system and method for adaptive and dynamic synchronization includes a data synchronization controller which enables synchronization of a plurality of different data types between a main computer and one or more remotely disposed computer elements. The controller includes an orchestrator which responds to requests for data synchronization for components in accordance with predetermined policies maintained by a policy management system. A synchronization interface is controlled by the orchestrator in accordance with the policies to select a synchronization engine to service requests for synchronization of different data types from the orchestrator. Synchronization may be handled for on demand and/or for on schedule requests for synchronization in the policy-based system and method.

Abstract: A mechanism for end-to-end mobile e-business applications for migration of business processes and business context between two or more clients and servers to provide transparency and reliability given unreliable networks and systems is disclosed. The e-business applications include mobile purchasing, retail point of sales, and inventory replenishment. The design of the novel mechanism takes into consideration migration of business processes and business context between clients and servers making the business activities transparent to the user of the mobile clients or networked clients.
