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.
