Abstract

A token-based centralized authentication method for providing access to a service provider to user information associated with a user'"'"'s relationship with the service provider includes the steps of: authenticating a user presenting a user token at a user terminal, the user token having stored thereon a user ID; deriving a resource identifier using at least two data input elements, the at least two data input elements including the user ID of the user and a service provider ID of the service provider, wherein the user information is stored in a storage network and the resource identifier is associated with the user information; retrieving the user information from the storage network using the resource identifier; and providing the retrieved user information to the service provider.

4. The method of claim 2, further comprising the steps of deriving a second resource identifier using at least an ID specific to the user token and a second data element that is not specific to the user token, and retrieving the data container using the second resource identifier.

5. The method of claim 2, wherein the user information retrieving step includes the step of reconstructing the user information from the plurality of storage nodes, wherein the reconstructed user information is provided to the service provider.

6. The method of claim 1, wherein the deriving step includes the step of deriving the resource identifier using a one way function.

7. The method of claim 1, further comprising the step of the one of the user terminal and a service provider agent forwarding the temporary transaction identifier to the other of the user terminal and the service provider agent.

8. The method of claim 7, wherein the authentication system issues the temporary transaction identifier to the user terminal, the method further comprising the step of authenticating the service provider after the user terminal forwards the temporary transaction identifier to the service provider agent.

9. The method of claim 7, wherein the authentication system issues the temporary transaction identifier to the service provider agent, the method further comprising the step of authenticating the service provider before authenticating the user.

10. The method of claim 1,

wherein the temporary transaction identifier is issued to the service provider agent, the temporary transaction identifier including a name identifier associated with the service provider, the method further comprising the steps of:

transmitting the temporary transaction identifier to the user terminal from the service provider agent for display of the name identifier to the user using the token;

receiving a consent indication from the user; and

after receipt of the consent indication, receiving the temporary transaction identifier from the user terminal.

11. The method of claim 1, wherein the storage network stores a plurality of separate sets of user information associated with the user, each set being associated with a respective user/service provider pair, wherein each set of user information is retrievable using a respective resource identifier derived using the user ID and a respective service provider ID.

12. The method of claim 1, wherein the user token is a hardware token.

13. The method of claim 1, further comprising the step of, after providing the retrieved user information to the service provider, receiving a set of user data for the user from the service provider for storage in the storage network in association with the resource identifier, wherein the storage network serves as the service provider'"'"'s permanent storage of the received user data.

14. The method of claim 1, wherein the user data is all or part of the user'"'"'s customer profile with the service provider.

15. The method of claim 1, wherein the step of deriving the resource identifier includes the steps of:

combining the user ID and service provider ID to provide a data element; and

encrypting the data element with a public key of a public/private key encryption pair.

16. A method of providing secure data storage and access to stored data, comprising the steps of:

receiving user information;

storing the user information in a dispersed storage network comprising a plurality of storage nodes in accordance with an information dispersal algorithm (IDA); and

associating the user information with a resource identifier for use in retrieving the user information from the dispersed storage network;

receiving the resource identifier and retrieving the user information from the dispersed storage network using the resource identifier, wherein the resource identifier is derived from an output of a one way function using at least two data input elements comprising a user ID and a service provider ID, wherein the user ID and service provider ID are separately received by an authentication system, wherein the authentication system derives the resource identifier using the user ID and service provider ID after receiving a temporary transaction identifier associated with an access or authentication request, the method further comprising the steps of;

issuing, from the authentication system and to one of a user terminal and a service provider agent, the temporary transaction identifier; and

receiving the temporary transaction identifier from the other of the user terminal and the service provider agent.

17. The method of claim 16, wherein the user information retrieving step includes the step of reconstructing the user information from the plurality of storage nodes.

18. The method of claim 16, wherein the user information is associated with a user'"'"'s relationship with a service provider, the method further comprising the step of providing the retrieved user information to the service provider.

19. A token-based centralized authentication and data retrieval system for providing access to a service provider to user information associated with a user'"'"'s relationship with the service provider, comprising:
