Abstract

A user-portable computing device configured as a smart card enables a user to carry identification information and to generate security tokens for use in authenticating the user to a service provider. The device includes memory for storing user identities as information cards that are exported to a host computer, presented to a user in visual form, and then selected for use in the authentication process. A security token service installed on the device issues a security token in response to a token request sent from the host computer that references the selected user identity. The security token service uses user attribute information stored on the user device to compose the claim assertions needed to issue the security token. The token is returned to the host computer and used to facilitate the authentication process.

a security token generator that;

receives a token request in reference to a first user identity of a plurality of first user identities from an identity management module executing on a host computing system, the receipt of the token request responsive to a security policy from a relying party;

generates a security token in accordance with the token request, using at least one user attribute;

retrieves information related to the user attribute to support claim assertions of the security token; and

issues the security token contained in an information card based on the token request, using the information related to the user attribute, the information card presented visually in a graphical user interface as a card-shaped picture.

2. The system of claim 1, wherein a plurality of information cards are presented visually.

3. The system of claim 2, wherein the information card is a smart card.

4. The system of claim 2, wherein at least one of the visually presented information cards is selectable.

5. The system of claim 2, wherein the information card comprises at least one of:

at least one self-issued card; and

at least one third-party managed card.

6. The system of claim 1, further comprises:

a service provider environment including at least one identity provider and at least one relying party;

the identity management module executing on a host computing system facilitates online interactions between a user and the service provider environment by managing identity requirements of the interactions; and

a network access connection to enable communications between the identity management module and the service provider environment.

7. The system of claim 6, wherein the identity management module executing on a host computing system:

(i) receives identity requirements from the service provider environment relating to a service request, (ii) identifies, as an eligible identity, any user identity among the plurality of first user identities that satisfies the identity requirements, (iii) generates a token request in reference to an eligible user identity, (iv) sends the token request to the security token generator of the user computing device, and (v) receives the security token issued by the security token generator in response to the token request.

8. The system of claim 6, wherein the identity management module further:

provides a plurality of second user identities each associated with a respective identity provider;

responsive to a security policy from a relying party, determines whether any user identity satisfies the security policy from among the plurality of first user identities and the plurality of second user identities;

enables the user to make a selection from among the user identities determined to satisfy the security policy;

responsive to a user selection drawn from the plurality of first user identities, provides a token request based on the selected user identity, communicates the token request to the security token generator of the user computing device, and receives the security token generated thereby; and

responsive to a user selection drawn from the plurality of second user identifies, provides a token request based on the selected user identity, communicates the token request to the identity provider associated with the selected user identity, and receives any security token issued by the identity provider occurring in response to the token request.

9. A method, comprising:

a host computing system generating a token request in reference to at least one exported user identity based on an identity management module executing on the host computing system;

a user computing device receiving the token request relative to the at least one exported user identity; and

the user computing device issuing a security token contained in an information card according to the token request and user attribute information associated with the at least one exported user identity, the information card presented visually for selection in a graphical user interface as a card-shaped picture,

wherein a security token generator retrieves a set of user attributes related to the security token and indicative of the first user identity.

10. The method of claim 9, further comprises:

the host computing system generating a token request based on the selected user identity; and
