Abstract

A client-side user agent operates in conjunction with an identity selector to institute and exercise privacy control management over user identities managed by the identity selector. The user agent includes the combination of a privacy enforcement engine, a storage of rulesets expressing user privacy preferences, and a preference editor. The editor enables the user to direct the composition of privacy preferences relative to user identities. The preferences can be applied to individual cards and to categorized groups of attributes. The engine evaluates the proper rulesets against the privacy policy of a service provider. The privacy preferences used by the engine are determined on the basis of specifications in a security policy indicating the attribute requirements for claims that purport to satisfy the security policy.

wherein when the identity manager determines a first user identity that satisfies the security policy and upon the user agent system determines that the privacy policy matches a ruleset associated with a first privacy preference relative to the first user identity, wherein the host computer provides the at least one information card representing the first user identity to the relying party.

2. The user agent system of claim 1, wherein the editor further includes:

enable execution of a process to define at least one category, and populate each category with a respective group of user identity attributes.

3. The user agent system of claim 2, wherein the engine further includes:

perform the evaluation using the privacy preference of any category referencing the at least one required attribute responsive to an indication of at least one required attribute as specified in the security policy requirements.

4. The user agent system of claim 1, wherein the editor further includes:

enable execution of a process to receive from the identity manager at least one indication of the at least one information card each representative of a user identity, and to determine a privacy preference for the at least one information card.

5. The user agent system of claim 4, wherein the engine further includes:

perform the evaluation using the privacy preference of the at least one information card determined by the identity manager to satisfy security policy requirements, in response to an indication of the determination from the identity manager.

6. In a combination including an identity manager and a user agent executing on a host computer, the combination for use in at least one online transaction with a relying party providing at least one security policy having requirements and at least one privacy policy, a method, comprising:

the identity manager managing a plurality of user identities and to determine whether any user identity satisfies the security policy requirements;

the user agent providing at least one privacy preference relative to at least one user identity;

the user agent receiving user selections indicating at least one privacy preference-related input pertaining to at least one user identity wherein the at least one user identity is represented by at least one information card used in completing a first online transaction with the relying party;

the user agent generating at least one privacy preference, using the user selections;

the user agent furnishing the at least one generated privacy preference to the providing step; and

the user agent evaluating at least one privacy preference against a privacy policy associated with the first online transaction and obtained from the relying party, the evaluating using the at least one privacy preference of any category referencing at least one required attribute;

wherein upon the identity manager determining a first user identity that satisfies the security policy and upon the user agent determining that the privacy policy matches a ruleset associated with a first privacy preference relative to the first user identity, the host computer providing the at least one information card representing the first user identity to the relying party.

7. The method of claim 6, further comprises:

the user agent conducting a process to define at least one category, populate each category with a respective group of user identity attributes, and determine a privacy preference for each category.

8. The method of claim 7, further comprises:

the user agent processing an indication of at least one required attribute as specified in security policy requirements; and

the user agent evaluating further includes evaluating the privacy preference of any category referencing the at latest one required attribute.

9. The method of claim 6, further comprises:

the user agent conducting a process to receive from the identity manager at least one indication of the at least one information card each representative of a user identity, and to determine a privacy preference for the at least one information card.

10. The method of claim 9, further comprises:

the user agent evaluating further includes evaluating the privacy preference of the at least one information card determined by the identity manager to satisfy security policy requirements.
