1. A method comprising:
- coupling a portable desktop device comprising portable desktop data stored therein to a host computer;
enabling access to the portable desktop data, wherein a user authentication operation is performed prior to supporting the portable desktop application;
executing on the host computer system a portable desktop application received from the portable desktop device;
at intervals known to the portable desktop device, transmitting from the host computer system to the portable desktop device a beat signal indicating a presence and operability of the host computer; and
,when the portable desktop device other than receives the beat signal at the known intervals, disabling access to the portable desktop data and preventing access thereto absent a further user authentication operation;
wherein a content of the beat signal transmitted from the host computer system to the portable desktop device varies in a fashion known to the portable desktop device; and
wherein the beat signal beats at intervals of between 1 and 30 milliseconds, such that timing of the beat signal is less than an amount of time required to disconnect and reconnect the portable desktop device.
