摘要:
An accessor function interfaces among a client, a relying party, and an identity provider. The identity provider can “manage” personal (i.e., self-asserted) information cards on behalf of a user, making the personal information cards available on clients on which the personal information cards are not installed. The client can be an untrusted client, vulnerable to attacks such as key logging, screen capture, and memory interrogation. The accessor function can also asked as a proxy for the relying party in terms of invoking and using the information cards system, for use with legacy relying parties.

A user engages in a transaction with a relying party. The relying party requests identity information from the user in a security policy and identifies transaction elements for an on-line business transaction. Typically, the security policy and transaction elements are transmitted together; the security policy can be as little as a request to conduct the on-line business transaction. The user identifies an information card that satisfies the security policy. The computer system requests a security token from the identity provider managing the information card, which can include requesting a transaction receipt for the transaction elements. The computer system then returns the security token (and the transaction receipt) to the relying party, to complete the transaction.

A system and method for dynamic rendering of information cards is provided. A card selector uses policies and rendering content to modify the presentation of information cards in the card selector. The policies and rendering content can be obtained from identity providers and relying parties. The rendering content can be obtained each time the card selector is invoked, just prior to rendering the information cards, or at other times specified in the policy. The rendering content can be displayed in a display area of the information card or in a content canvas outside the display area of the information card.

A relying party can have a security policy. The security policy can include claims that are categorized other than “required” and “optional”. The user can specify, in a user policy, whether or not to include in a request for a security token from an identity provider claims that are not “required”.
摘要:
A computer system accesses metadata about an information card. The metadata can be stored locally or remotely (for example, at an identity provider). A metadata engine can be used to generate data to be provided to the user from the metadata: this data can take any desired form, such as an advertisement, a state of the user's account, or a policy update, among other possibilities.

A user desires to select information about himself. The system uses policies applicable to the display of the user's information and metadata about the user and the information to determine modified presentations of the user's information. The modified information can include visual and non-visual cues (such as aural, olfactory, or tactile). The system then displays the modified information, presenting the user with the visual and non-visual cues about the information.
摘要:
A computer system accesses reputation information about a relying party. The reputation information can be stored locally or remotely (for example, at an identity provider or reputation service). A reputation information engine can be used to provide the reputation information to the user. The user can then use the reputation information in performing a transaction with the relying party.
摘要:
The user can associate metadata with information cards. The metadata can include, among other possibilities, string names, icons, user policies, containers, and hierarchies. The metadata is stored by the computer system. The metadata can then be used to filter the set of information cards that can satisfy a security policy from a relying party.
摘要:
A correlation operator &THgr; provides a way for the results of sub-queries to be correlated. The correlation operator &THgr; has an implied existential quantifier property (i.e., a “for some” property) and is satisfied if any record matches its sub-query. If no record is found that matches the correlation operator &THgr;'s sub-query, then the correlation operator &THgr; query fails. The implicit existential quantifier property of the correlation operator &THgr; can be converted into a universal quantifier property (i.e., a “for all” property) by transformation of the query. The correlation operator &THgr; uses an algebra to resolve into flags attached to appropriate operators in the sub-query. After the correlation operator &THgr; is eliminated from the query, the query can be performed. The operator flags perform the correlation as part of the sub-query. The correlation operator &THgr; can be inserted explicitly by the user if she knows what data she desires to be correlated. Alternatively, the correlation operator can be inserted by the schema automatically to improve the expected results of the query.
