Techniques for recovering from unexpected removal of (or other unexpected power loss) a flash memory device from a computer system. An interpolated device driver notes whenever the flash memory device is unexpectedly removed, or otherwise unexpectedly powers off or enters a locked state. If the flash memory device is reinserted, the interpolated device driver reinitializes the flash memory device, and satisfies any flash memory device security protocol, so the flash memory device and the computer system can be restored to their status just before unexpected removal. The interpolated device driver caches requests to the flash memory device, and when status is restored to just before removal, replays those requests to the flash memory device, so the flash memory device responds to those requests as if it had ever been removed. The computer system does not notice any break in service by the flash memory device due to removal and reinsertion.

Recovering from unexpected flash drive removal

A method for transmitting digital data to a recipient via a communications network includes providing digital data and digitally signing the digital data using N cryptographic keys. Each of the N cryptographic keys is associated with a same sender of the digital data, and N&#x3e;1. The recipient receives the digital data and verifies the digital signature using N cryptographic keys associated with the N cryptographic keys used to sign the digital data. In dependence upon verifying the digital signature, the recipient accepts the digital data as being authentic.

Data authentication using plural electronic keys

In accordance with the invention there is provided a method of authorizing an individual comprising the steps of: receiving authorization data from the individual; determining based on previously stored data, at least a processor for performing an authorization process; using the at least a processor and the authorization data, performing the authorization process to one of authorize an individual and fail to authorize the individual; and wherein stored data results in different determined processors for different authorization operations and wherein at least some of the authorization operations are determined for performance by a same server processor.

A biometric sensing device includes sensing arrays for sensing a biological surface swiped across the sensing arrays in an arbitrary direction. This device allows for simultaneously sensing different features of a biological surface where the features have the smallest distinguishable features of different size. Using the technique of interleaving partial images, the resolution of the biometric sensing device is increased. Therefore, a small and robust biometric sensing device is provided, which allows for sensing high resolution images.
