Abstract:
1. A system for porting user data from one computer to another, comprising: a memory device configured to store the user data and a public key; and a smart card associated with a user that alternately enables access to the user data on the memory device when both the memory device and smart card are interfaced with a common computer and disables access to the user data when the smart card is absent; wherein the public key is sent from the memory device to the smart card, wherein the smart card contains a private key, and wherein access to the user data in the memory device is enabled upon verification that the public key and the private key are associated as a public/private key pair such that the public and private keys are components of an asymmetric cryptographic system whereby data encrypted by the public key is decrypted by the private key; and wherein the smart card is configured to pass an encryption key to the memory device for decryption of data read from the memory device, and for encryption of data to be stored on the memory device.
