Portable storage device for providing secure and mobile information
First Claim
1. A data processing configuration, comprising:
- a portable personal data device including a storage element, a radio frequency transceiver, and a state machine suitable for implementing a wireless protocol enabling transmission and receipt of data via the transceiver, wherein the storage element includes desktop data personal to a corresponding user and wherein the personal data device is configured to transmit, via the transceiver, a wireless signal identifying the personal data device;
a host workstation including at least one processor connected to a volatile system memory, a transceiver suitable for receiving the wireless signal and for determining the personal data device identifying information;
means for securely accessing a database containing an entry for each of the at least one personal data devices, wherein each entry includes personal data device identification and password information;
workstation means for determining if the wireless signal is being transmitted by a recognized personal data device;
responsive to recognizing the personal data device, means for authorizing a wireless connection between the personal data device and the workstation;
responsive to successfully authorizing the connection, workstation means for wirelessly accessing the personal data stored on the personal data device to enable the user to access the personal data via the workstation.

Abstract
A system and method in which user personalized directories of information are maintained on portable and wireless personal data devices. The personal data devices include a storage medium, a wireless transmitter, and a state machine suitable for implementing a wireless protocol such as Bluetooth or IEEE 802.11b. Typically, the personal data devices are small enough to clip or otherwise attach to a user'"'"'s clothing. The personal data device is configured to transmit a signal that includes personal data device (PDD) identification information. When the user is within range of a suitably enabled workstation, the workstation “hears” the signal and deciphers the PDD ID. If the user attempts to log on to the network, the workstation will prompt the user for a username/password combination and compare the user'"'"'s responses to information password and user ID information stored in a table that is accessible to the workstation. If the workstation is able to confirm the user ID and password, it may then perform a second authorization sequence in which the workstation sends a workstation password to the personal data device. The workstation may also send additional information such as a directory that the workstation proposes to use as a mount point. This proposed directory typically specifies the user'"'"'s personalized directory. If the personal data device is able to confirm the workstation password and the proposed directory as valid, a “connection” is established between the personal data device and the workstation. The workstation is then able to mount the user'"'"'s directory on the personal data device and provide the user'"'"'s personal desktop to him or her.
