Restricting access to data on portable storage media based on access to a private intranet

摘要

Systems, products, and methods are disclosed for enabling access to encrypted data stored on a portable storage medium. In one embodiment, an attempt to communicate with a certain intranet is made. If this attempt succeeds, then access is granted to the data stored on the portable storage device, but if access to the intranet is not granted, then access to the data stored on the portable storage device is also not granted. Denying access can include preventing the portable storage device from even being recognized by a requesting device, being recognized but not presented, or can include showing that such encrypted data exists, but denying access to the data in an unencrypted format.

主权项

1. A method of enabling access to encrypted data stored on a portable storage medium, the method comprising:
attempting, by the portable storage medium, to communicate with an intranet, wherein the portable storage medium includes a radio configured to communicate directly with the intranet using a wireless communications network independent of a host device to determine if the intranet is a predetermined private intranet; receiving a request at the host device to access the encrypted data stored on the portable storage medium; determining, by the portable storage medium using the radio, that the intranet is the predetermined private intranet that, when identified by the portable storage medium as the predetermined private intranet, allows access to the encrypted data by the host device; and providing the host device access to the encrypted data stored on the portable storage medium in an unencrypted form.
