Systems and methodologies that proactively push down and enforce policies of a server(s) on mobile devices, when such devices connect to the server(s) for data synchronization. The subject invention employs a policy delivery and enforcement logic that is integrated as part of a communication channel (e.g. a single communication channel) with the mobile device(s). A hand shake can take place between the mobile devices and the server every time that a new policy occurs. Accordingly, non-compliant devices are denied service from the server.

In a system for preventing automobile theft, select automotive components are embedded with digital information and devices, including a unique public key, a unique private key, a decryption/encryption module, and a network address. Upon assembly of a vehicle, the components form addressable nodes of that vehicle. Relevant digital information of all components is recorded in a proprietary, highly secure data base at the time of manufacture, and updated for vehicular repairs. Only registered agents may access the data base or submit updates to the federal network. During refueling or re-charging of a vehicle, a digital handshake compares public keys of the vehicular components to the proprietary data base, and confirms the integrity of at least some components by a public-key/private-key challenge and response. If components have been reported stolen, or other irregularities are detected in the vehicle's network of components during the hand shake process, the vehicle is disabled, and a message is automatically transmitted to one or more law enforcement agencies, identifying the vehicle and its location.

The microcomputer calculates a projection optical axis correction value based on hand shake detection signals from a sensor and controls the aforementioned actuator based on the correction value. With this control, shakes of projected images due to hand shakes are prevented.
