  • Access system utilizing multiple factor identification and authentication
    Patent number: 7178025
    Abstract: A method of authenticating a user to use a system includes using a provider token to generate a random value. The token generates a derived key based at least in part on a token-provided salt value and a user-provided password. The provider generates a token unlock key based at least in part on the derived key and sends it to the token. First and second challenge data instances are generated by the provider and the token, respectively, and the process is terminated if the challenge data instances are determined not to match. If the challenge data instances are determined to match, then an encrypted data transfer system is established between the token and the provider, and the token unlocks locked private data stored on the token. The user is authenticated for secured use of the system based at least in part on the unlocked private data.
