Data access and retrieval for portable devices

摘要

This paper addresses the need of data access and data retrieval when the device loses the access from a legitimate user by defining specific security levels for user defined sensitive data in the MeeGo device. Proposed application provides protection mechanism which manages authentication checks and blocks access to this data for corresponding security levels breeched. It activates predefined cloud resource and transfers critical data after a particular security level-breach because of which critical data no-longer resides on the MeeGo device. It invokes integrated modules for Notifying Unauthorized Access, Approximating the Device Location using GeoClue Services available in middle-layer MeeGo architecture and Cloud Data Syncing to enable the authentic user to retrieve sensitive data from the cloud. Provision for Data Removal from the disk to safeguard it is handled.
